A good ventilation system has the ability to protect you from all kinds of health problems. Whether it’s headaches, allergies, asthma, rashes or sinusitis, they can all be reduced by having good ventilation.

By installing a mechanical ventilation system, like those sold at Ventilation Megastore, you’ll be sure to see the health benefits in no time. 

Reducing the spread of respiratory infections

During the COVID-19 pandemic, we saw the world become acutely aware of how to reduce the spread of respiratory infections and the actions we need to take to do this. 

These actions helped to save lives in the pandemic, and the same principles also apply to coughs, colds, flu and other illnesses.

When somebody with a respiratory infection breathes, speaks, coughs or sneezes, they release small particles into the air which contain the infection. These can then be breathed in by other people, come into contact with their eyes, nose or mouth, or even be passed from person to person by touch. 

However, proper airflow and ventilation can reduce the spread of infection by helping to remove air that contains infectious particles. Our mechanical ventilation heat recovery (MVHR) systems work to remove germs by continuously extracting the infected air and replacing it with fresh, filtered air.

Reducing the presence of damp and mould

Mould can be a big problem for our health, making us more likely to have respiratory problems and infections, allergies and asthma. But there is a way to prevent the growth of mould and reduce these health risks.

The only way to truly prevent mould permanently is to remove the conditions that allow it to grow. By providing proper airflow, a quality ventilation system will help to remove moist air before water vapour can settle and soak into surfaces, denying mould the environment it needs to grow.

So, if you want to protect your home from mould, our whole-house ventilation systems are a great solution to help keep it at bay.

Helping to control hay fever

The weather in spring and summer can wreak havoc for hay fever sufferers, causing symptoms like sneezing, blocked noses, itchy eyes, coughs and headaches. 

Many try to avoid spending time outdoors to reduce the risk of hay fever symptoms, but our homes can often be just as bad.

Whilst you’ll struggle to keep pollen out of your home, a good ventilation system can help you to remove the pollen in the air. Plus, it can help to keep things cool without having to open your windows, which would make things worse by letting more pollen in.

An MVHR system fitted with HEPA filters will draw fresh air into the home while capturing the pollen. At the same time, the system will draw stale air out of the property, quietly making the air in your home fresher and cleaner.

If you want to improve your health by installing a ventilation system in your home (and who wouldn’t?) then our team of experts are on hand to help. Contact us today for simple queries, no-obligation quotations or technical advice. 

Ever wondered if there are regulations in place about workplace air quality and ventilation? Well, the answer is yes.

It’s the Health and Safety Executive (HSE) that sets these rules out through the Workplace (Health, Safety and Welfare) Regulations 1992. These make sure that air quality remains adequate and safe for all employees.

You can read the full copy of these regulations here. However, if you’d just like the highlights, then we’ll talk you through what is expected of you as an employer and what you can expect from your workplace as an employee.

Air quality regulations

In the UK, “effective and suitable provision” should be made by employers to “ensure that every enclosed workplace is ventilated by a sufficient quantity of fresh or purified air.” 

This means that any work space, whether it’s an office, factory or shop, should have systems in place which replace unwanted air with fresh, clean air. This will also help to prevent workplaces from getting stuffy and overheating.

The government regulations state that workplaces should normally be supplied with at least 5-8 litres of fresh air per second, per occupant, but more may be needed in more crowded areas, where machinery or equipment is used or where people are doing strenuous work.

This fresh air should be as clean as possible to avoid employees inhaling anything undesirable, like pollution or pollen, that could make them unwell. To do this, employers need to make sure that ventilation systems are located away from places where there could be contaminated air, such as near roads or near an exhaust.

The regulations also state that mechanical ventilation systems should be provided for some or all of a workplace, if this is necessary to ensure adequate ventilation. When re-circulating air, these systems should have adequate filters to remove impurities and their fresh air inlets should always be kept open. All of our units at Ventilation Megastore adhere to these rules.

Systems also need to be regularly cleaned, tested and maintained to ensure they’re kept clean and free from anything which may cause the air to become contaminated.

It is important to note that, while Regulation 6 is a great resource to refer to for general workplace ventilation, it is not designed to help with controlling employees’ exposure to any harmful substances such as asbestos, lead or ionising radiations. More details on these regulations can be found here.

Will my business benefit from mechanical ventilation?

Absolutely! Mechanical ventilation heat recovery (MVHR) systems are the perfect solution if your firm is struggling to meet the required regulations for ventilation, or if you simply want to create a better environment for your staff.

Our MVHR units are designed to help your business reduce energy bills. What’s more, they also look after the environment with a highly efficient heat exchanger.

The system will remove stale air in the workplace while ensuring that your team has access to fresh, filtered air all year round. So you don’t have to worry about opening any windows and making your staff chilly!

What’s more, filters are easy to access and washable, with the heat exchangers removable for hassle-free cleaning, meaning that the units are simple to maintain. Built with efficiency in mind, they’ll fit into small spaces within your premises without taking up too much room.

So, if you’re interested in getting your own MVHR system, we’ll work with you to find the right solution for your workspace. We’ll take into account the size of your workspace, the number of occupants and the nature of your work, to ensure everyone can benefit from safe, clean and fresh air - no matter the weather.

Whether you’re a national house builder looking to appeal to more environmentally conscious house buyers, or simply wanting to reduce your energy consumption within your own home, we’re here to lend a hand!

To help you reduce your energy consumption (also those high energy bills!) and become more sustainable, we’re exploring all of the different options currently available on the market. We'll take a look at both traditional methods and more innovative approaches, such as mechanical heat recovery ventilation systems.

Traditional methods to reduce energy consumption

Double or triple glazed windows

Thanks to its insulating properties of gas (which is in between your windows!), having double or even triple glazed glass in windows and doors will instantly minimise heat loss during winter and heat ingress during summer, reducing your energy bills.

Loft insulation

Approximately a quarter of all heat in a home is lost through the roof of an uninsulated or poorly insulated home. Having effective insulation (check out our sister company, SuperFOIL!) will substantially reduce heat loss and bills.

Draught excluders

Draught excluders are a relatively inexpensive way to help keep out cold draughts, while keeping warm air inside your home. The most common place for these is around your front and rear doors, although some households will have window draught excluders too. Over time, these can become flattened or broken so it’s worth checking if yours can be upgraded.

Cavity wall insulation

Cavity wall insulation is the insulating material that is within the cavity of your property (i.e. the space between the inner and outer walls). The insulation works by trapping warm air while preventing air from circling around the cavity. This can help keep a home warm in winter and cool in summer by preventing heat from making it through the walls.

Thick curtains

Thicker curtains can prevent heat loss through the windows and close off any draughts. Energy efficient curtains (or thermal/insulated curtains) are thick, heavy curtains containing a layer of acrylic foam to provide additional insulation benefits. Thermal curtains can help to prevent heat and air from escaping (or entering from outside) around your windows. 

Smart thermostats

Smart thermostats are an efficient way to control your heating; many of them will allow you to change your heating temperatures remotely or they can adapt to your routine, meaning that your house isn’t being heated while you’re out.

Radiator reflective panels

Radiator reflective panels, such as SuperFOIL Radpacks, use reflective material to encourage heat to come back into the room, rather than being lost through walls behind the radiator.

energy saving

Although these methods help to prevent heat loss, they also prevent air circulation

While all of the above methods are effective in retaining heat and reducing heat loss, they unfortunately also can prevent good ventilation. Newly-built homes can be particularly susceptible to poor air circulation, as they are typically very airtight and highly efficient in retaining heat.

Now that we’re seeing more and more homes become more airtight, this creates a need for improved ventilation. Without this, many problems may arise, including condensation, damp, mould, allergens such as pollen and general poor indoor air quality.

So with this in mind, what if we told you that we can provide effective, energy efficient ventilation in your home AND reduce your energy bills….

Mechanical ventilation will help you to save energy

Our energy efficient Mechanical Ventilation Heat Recovery (MVHR) systems will not only ensure that you have a fresh stream of filtered air within your home 24/7, but will also contribute to reducing the heating and cooling demands of your home - meaning you’ll save money too.

MVHR works by removing polluted air from your property and replacing it with filtered air. Not only does it ensure that you have a fresh stream of air within your home 24/7, the heat recovery element of the system uses the warmth of the extracted air to heat up the inbound air. This means that not only are you reducing your heating bills, you’re also helping the environment by not using that extra energy to heat up your home!

Whether you’re familiar with MVHR systems, or completely new to the concept, our team of experts are on hand to assist in any way they can. Get in touch today for simple queries, no-obligation quotations or technical advice.

Having a constant stream of fresh air is important in every household to help prevent illness, condensation, damp and mould.

While there are many options available to improve ventilation, the advantages of whole house ventilation using a mechanical heat recovery system is often the most effective choice…read on to find out why!

Why do we need ventilation?

Ventilation is the process of removing polluted, stale air from a room and supplying fresh, clean air from outside. This can be done by natural or mechanical ventilation, or a combination of the two.

In 2023, 3.8% of homes in England have some form of damp problem - equating to approximately 912,000 households. What’s more, the NHS estimates that it could save up to £38 million a year on treating patients with damp and mould-related illnesses, if issues were rectified.

Mould and damp is caused by condensation - when humid air comes into contact with cold surfaces to form water droplets. It typically occurs when temperatures drop overnight, resulting in us often waking up with water droplets on our windows (and sometimes walls and ceilings), mainly in winter months.

Good ventilation will help to reduce condensation by removing the moist air from your home before it has a chance to settle on a cool surface. As well as causing damage to your property which may be costly to repair, damp and mould can also have serious effects on your health - especially to individuals with underlying respiratory conditions, such as asthma.

Different types of ventilation

Depending on your home and budget, there are different solutions for increased ventilation that you can adopt, but they vary in their effectiveness.

Natural ventilation

Rather than using any sort of mechanical element to push air around, natural ventilation relies solely on gaps in the building fabric, combined with any trickle vents or air bricks that may have been installed.

Natural ventilation can also be supplemented by opening windows and doors, however this is often only done in the warmer weather.

This type of ventilation is the cheapest and simplest option, and because of this, there are quite a few drawbacks. 

Trickle vents don’t let much air flow unless it’s windy and they can produce a through-draught, whereas opening doors and windows to the outside can quickly make a home cold in winter. In the summer months, this method will likely let in lots of pollen and insects, and can also let in other pollutants from outside such as vehicle fumes.

Extractor fans

Extractor fans are one step up from natural ventilation, and have a simple mechanical element involved. In most houses, they’re typically located in rooms that generate more water vapour, such as kitchens and bathrooms.

They are effective in controlling moisture within the rooms that they are positioned in, however they also suck out the warm air that rises to the ceiling and they are relatively limited in the area they can cover. If you leave a door open after a bath or shower and water vapour escapes, it will travel around the house and can increase moisture levels in areas the extractor fan can’t reach.

While it’s essential to have extractor fans in your home, often these aren’t enough to completely reduce levels of moisture.

Mechanical ventilation heat recovery (whole house ventilation)

Mechanical ventilation heat recovery (MVHR) systems are modern, efficient units that provide ventilation to an entire house.

MVHR systems will ensure that condensation (and therefore damp and mould that can follow) doesn’t become an issue in your home, by removing all moisture-laden air and replacing it with filtered, heated air from outside.

As well as removing moisture, MVHR will also remove any harmful irritants in the air such as germs and pollen, causing illness and hay fever. They are also energy efficient, using no more than extractor fans because the built-in heat exchanger recovers warmth from outgoing air to heat the fresh air coming into the building. This means that it’s highly efficient, and helps to reduce your heating bills.

Sick building syndrome is a real health issue that affects office workers throughout the world.

Shared work environments with poor ventilation allow germs, dust, smoke and fumes to circulate, affecting the health of everyone present and spreading illnesses throughout a workforce.

If your organisation seems to have a high number of people falling ill or if people seem to be battling against constant bouts of coughs, colds or other contagious ailments, it could be time to upgrade your building’s ventilation.

How to improve natural ventilation

The best way to improve natural ventilation is to have windows and doors open throughout the day, however this can be tricky (and unpleasant!) in the colder, winter months when temperatures are low.

It might be tempting to block out every draught in winter, but you should try to keep trickle vents open so that a small amount of fresh air can replace the more polluted air in the building. Trickle vents are small so they don’t have a huge impact but if the wind is blowing outside and there are vents open on windows on either side of your office, they can help to create a gentle current of fresh air to slowly whisk away airborne germs.

In the summer or when the air is still outside, you’ll need to increase the airflow by opening windows but even this might not be enough on a really still day. You can help the air to flow more easily by cleverly positioning fans to direct the air from windows on one side of the office to the other, but this can make life miserable for anyone with hayfever because pollen may also be wafting through your office along with the fresh air.

As well as the problems of letting in pollen and letting out warmth, natural ventilation is also problematic in urban areas because the outside air may be polluted.

Mechanical ventilation should be considered too

Extractor fans are a must in kitchens and toilets, where smells can linger and moisture can build, but just like open windows, they also let out the heat from a room.

The most effective way to improve ventilation in the workplace is by investing in a mechanical heat recovery ventilation (MVHR) system for your office.

MVHR works by removing the old, polluted air from the building and replacing it with fresh air that gets filtered as it comes in. The best thing about MVHR is that it uses the warmth of the air that the system extracts to heat up the inbound air. Using no more power than an extractor fan, these systems help your workplace to have fresh, clean air while also staying warm and energy efficient.

All year round, it’s the perfect solution for any workplace.

Better ventilation can reduce sick days

By installing a mechanical ventilation system within your office environment, this will remove all nasty pollutants in the air and replace it with fresh, clean air for your employees to safely breathe in. This will help to prevent illnesses being passed on to team members, hopefully resulting in less sick days being taken - meaning that your business should be more productive, with everyone feeling happier and healthier.

Everyone is aware of outdoor air pollution and the harmful effects that it can have on humans, but the dangers from indoor air pollution can be equally as damaging - especially for households with children or older people.

High-quality indoor air is absolutely crucial to our health. As we spend a significant amount of time indoors in the UK (especially in winter!), it’s imperative that we don’t expose ourselves to harmful substances while doing so.

What exactly is indoor air pollution?

Indoor air pollution includes dust, dirt or gases that are within the air inside buildings, such as homes, offices or schools. In its simplest terms, it refers to any contamination of the air indoors. 

You’ll probably have noticed when your home feels stuffy, humid or dusty but you might not realise that there can be serious consequences if you allow pollutants to build unchecked.

Most indoor air pollutants are small enough in size to enter your lungs, and can make symptoms of a lung condition (such as asthma) significantly worse.

There are many different types of indoor air pollution, including:

Why is it dangerous?

Indoor air pollution is fast becoming a more significant issue, as homes are getting even more energy efficient.

To keep your home warmer in winter, you’ve probably reduced the number of draughts around windows and doors or have upgraded your insulation. While that makes your home more energy efficient, it will also make your home more airtight, meaning that the air inside can quickly become stagnant and pollution levels will undoubtedly rise as a result.

According to Asthma + Lung UK, poor indoor air quality has been linked to many different lung diseases such as asthma, lung cancer and COPD. It’s also been linked to an increased risk of strokes and heart disease.

Although those with a lung condition are more likely to be affected, anyone can be susceptible to side effects as a result of indoor air pollution. Children are also more at risk, as their lungs are still developing - their airways are smaller, so inflammation can cause them to narrow more easily than adults.

Symptoms of poor indoor air quality include irritation of the eyes, nose and throat, headaches, fatigue, dizziness, shortness of breath, coughing and sneezing, and sinus congestion. The best way to tell if your home is causing your symptoms is to keep an eye on how you’re feeling after a few hours out of the house. If you’re feeling better, it’s likely to be your house doing the damage.

Breathing in dust inside

Here’s some examples of things in your home that produce air pollution

How can I reduce my indoor air pollution?

The best way to quickly and safely reduce levels of indoor air pollution is to invest in reliable, efficient ventilation.

Opening windows throughout the night and day is one solution, but it will also make your home cold, and small openings won’t do much on a still day. Extractor fans are also effective in removing warm, humid air, but let out heat. They also only remove the air from a home and don’t replace it.

Mechanical ventilation heat recovery (MVHR) units are the perfect solution - they ensure that your home has a constant stream of fresh, warm air, while removing polluted air from the property at the same time. Not only that, but they also use the extracted air to warm the air that the system draws into the house, protecting the energy efficiency of your central heating.

The system works by extracting moist, stale air from the home and replacing it with fresh air from outside via a duct network. These ducts bring in clean air from outdoors, passing via a heat exchanger to warm it up on its way in.

The clever central unit will automatically control and monitor the air quality within the home, making any adjustments necessary to ensure that there is a continuous stream of ventilated air at all times in your property. Not only will it remove the pollutants, it’ll also remove any infectious particles along with it - helping to reduce illnesses and air-related symptoms in one go.

The cold, wintery weather often tempts homeowners to try and preserve as much heat as possible inside their homes, which means that moisture-laden air produced by everyday activities has nowhere to escape to, with windows and doors (understandably) remaining closed.

Unfortunately, due to the large difference in temperature between the cold exterior and warm interior of your home, houses are much more prone to condensation and damp in the colder months. However, there is a solution to keep you warm whilst preventing condensation from forming…but before we explain, it’s important to understand what causes condensation and why it’s a problem.

What causes damp and condensation in winter?

There are several different causes of damp and condensation in winter - with each of your efforts to keep your household warm likely contributing.

In order to preserve as much heat as possible, homeowners are a lot more likely to keep their windows and doors closed during the winter months. Unfortunately, this ensures that any moisture created throughout the day - such as from showering, washing, bathing or cooking - will remain trapped inside. As a result, the moisture in the air will then be able to condense and settle on surfaces.

People also tend to invest in draught excluders for the winter months to keep any chilly air from the outside that may slip through gaps and into the home. This also means that any interior humidity and moisture won’t be able to escape through these ‘plugged’ gaps, and will be confined to the building.

In winter, you’re much more likely to have your traditional heating systems on full blast, such as fires and radiators. Whilst it keeps your household warm, it also results in increased water vapour in the air, which can then condense onto cooler surfaces such as windows.

condensation

It’s important to keep damp and condensation to a minimum

Although you may think that condensation is more of an annoying inconvenience to deal with, it can actually cause major problems to your home if you’re not careful.

If causes of damp and condensation are not addressed, it can cause substantial damage to properties and may even result in a hefty bill to replace any affected plasterwork, window frames and door frames. If allowed to damage wooden frames, the fibres within the wood can spread apart, allowing more moisture to soak in - which may then freeze, causing the wood to split.

Treating wood rot is not an easy task, and will often require a professional to carry out expensive remedial works. Condensation can also result in peeling paint and plaster, which again, is not easy to fix and can cause homeowners some serious problems - especially if you ever want to sell up and move home.

Damp and condensation also lead to mould and fungus, which can be a serious health risk.

How can I reduce condensation whilst staying warm?

Luckily for all homeowners, there IS a simple solution to staying warm, whilst also keeping moisture and humidity in your home to a minimum.

At Ventilation Megastore, we are experts in providing Mechanical Heat Recovery Ventilation (MVHR) for your home - allowing you to have access to fresh, filtered (and heated!) air.

An MVHR system will remove the moist, humid air from your home and replace it with fresh, filtered air from outside. Heat energy from the property is also recovered, and then transferred to the fresh incoming air via a heat exchanger - meaning that the fresh air is also heating your home too, which is vital in the colder months (and will save you money on those heating bills!).

By removing the moisture laden air from your house before it has a chance to settle, this will dramatically reduce any dampness and condensation from occurring, whilst allowing you to keep those windows and doors firmly shut.

A hot, stuffy house is never ideal, especially when you’re trying to sleep. If your home is well insulated, then unfortunately, it’ll also be good at keeping the summer warmth in, even when you’d rather it didn’t!

Following our most recent heatwave (and many before that too in 2023), we thought we’d share our advice on how to avoid an overheated home.

How to keep your home as cool as possible

A heatwave in Britain can be very tricky to deal with, as our homes just aren’t built for such hot temperatures - they're designed to keep heat in, not out!

When the weather is hot outside, the temperature of your home will also rise, which can be very uncomfortable for you and your family. Fear not though, as we’ve put together our top tips on how to keep your home cool.

Draw your curtains and blinds

It may be tempting to throw open the windows on a hot day but by closing your curtains and blinds during the day, this will help to block out the heat from the sun. If you can, try to choose a lighter colour, as darker colours may actually add to the heat rather than reflecting it.

Choose when to open and close windows

During the day, it’s best to keep windows closed in rooms that are facing the sun, as this will let in the external heat. When the temperature drops into the evening, this is the perfect time to open them all up to allow for cool air to enter your home - hopefully aiding a better night’s sleep.

Put your extractor fans to good use

Extractor fans aren’t just good for ventilation, they can also remove some of the warm air caused by the weather too. Open up your internal doors and leave your kitchen and bathroom extractor fans running for a while to remove some excess heat - make sure to shut the doors again when you switch the fans off though.

Air conditioning

Air conditioning is great but units can use a lot of power, which can make them costly and bad for the environment. You can boost the efficiency of your system by closing windows, curtains and blinds to keep the hot air out and also prevent the cold air escaping, but you don’t need a big, expensive air-con unit to stay cool.

As well as following the above tips, you can also improvise with a wet sheet and some ice: By hanging a wet sheet in front of an open window, this will cool the warm air as it enters the home.

If you have a fan, then place a deep dish of ice in front of it - the fan will then pick up the water mist and make the breeze cool. If you don’t mind spending a little, then there are many portable, small DIY air-con units available on the market - you’ll just need ice and a power source to use them.

Select your rooms wisely

Some rooms in your house will likely be cooler than others, usually due to whether they’re in the shade or not. Downstairs will typically be cooler than upstairs, as heat will rise - so if it’s unbearably hot at night, you may consider sleeping downstairs for some relief.

Whole-house ventilation will control the heat

The best and most efficient way to ensure that your home maintains a safe, comfortable temperature at all times is whole-house ventilation. Once installed, our high-quality units will do all of the hard work for you - purifying fresh air and circulating it through the house while extracting the hot air that rises to the ceiling.

By investing in a mechanical ventilation heat recovery (MVHR) system, you won’t need to worry about sleeping downstairs or running your extractor fans excessively, because this will ensure that the temperature remains pleasant.

When the outdoor temperature is cooler than indoors, our MVHR systems will work in reverse. The unit extracts warm air from your home and sends it outside, bringing in cooler air from outside. By extracting humid air from inside the house and replacing it with fresh, dry air, the system will improve indoor air quality too.

The flow of cooler air means that you can keep your windows closed during the day and night, whilst still enjoying a cooler home.
