How Do You Clean MVHR Filters?

How Do You Clean MVHR Filters?

Mechanical Ventilation with Heat Recovery (MVHR) systems have become increasingly popular in recent years due to their ability to provide a constant supply of fresh, filtered air while recovering the heat from the outgoing stale air. These systems have filters that need to be cleaned regularly to maintain their efficiency and prevent the build-up of pollutants. So let's talk about how to clean MVHR Filters.

Here are some tips for cleaning MVHR filters:

1. Understand the filter type:

Before cleaning the filter, it is important to understand the type of filter you have. Most MVHR systems have either a washable or a replaceable filter. Washable filters are made of a fine mesh that can be cleaned and reused, while replaceable filters are made of paper or other disposable materials and must be replaced periodically.

2. Turn off the system:

To clean the filter, turn off the MVHR system to prevent the fan from pushing dirt and debris deeper into the system.

3. Remove the filter:

Remove the filter from the MVHR system. This may require unscrewing a cover or removing a panel. Be sure to handle the filter carefully to avoid damaging it.

4. Clean the filter:

Washable filters can be cleaned with warm soapy water or a mild detergent. Rinse the filter thoroughly and let it dry completely before reinstalling. Replaceable filters should be replaced according to the manufacturer's recommendations.

5. Vacuum the system:

While the filter is out, use a vacuum cleaner to clean the interior of the MVHR system. Be sure to remove any visible dust or debris. Pay close attention to the fan blades and the heat exchanger, which are areas where dirt and debris can accumulate.

6. Reinstall the filter:

Once the filter is clean and the MVHR system is vacuumed, reinstall the filter. Make sure it is installed correctly and securely to prevent air leaks.

7. Turn on the system:

Turn the MVHR system back on and allow it to run for a few minutes to ensure proper airflow.

8. Regular maintenance:

Regular maintenance is crucial for the proper functioning of your MVHR system. Clean washable filters every 3-6 months, depending on usage, and replace disposable filters according to the manufacturer's recommendations.

In summary, cleaning the filters of your MVHR system is an essential part of its maintenance. Understanding the type of filter you have and following the manufacturer's recommendations for cleaning and replacing filters is crucial for the efficiency and longevity of your system.

In addition to the filters inside the MVHR unit, some systems also have in-line filters that are located in the ductwork. These filters may be more difficult to access and clean, but they are just as important for maintaining the air quality in your home. Here are some tips for cleaning in-line filters:

Identify the location of the filter:

The first step is to identify the location of the in-line filter. This may require a visual inspection of the ductwork or refer to the system's manual. In-line filters are typically located near the air intake or near the MVHR unit.

Turn off the system:

As with the filters inside the MVHR unit, turn off the system to prevent the fan from pushing dirt and debris further into the system.

Remove the filter:

In-line filters may be located in a filter box or a filter grille. Remove the filter box cover or the grille cover to access the filter. Be careful not to damage the filter or the ductwork.

Clean the filter:

In-line filters may be washable or replaceable. If the filter is washable, use warm soapy water or a mild detergent to clean it. Rinse the filter thoroughly and let it dry completely before reinstalling. If the filter is replaceable, replace it according to the manufacturer's recommendations.

Vacuum the ductwork:

While the filter is out, use a vacuum cleaner to clean the ductwork around the filter. Be sure to remove any visible dust or debris. Pay close attention to the area around the filter and the air intake, which are areas where dirt and debris can accumulate.

Reinstall the filter:

Once the filter is clean and the ductwork is vacuumed, reinstall the filter. Make sure it is installed correctly and securely to prevent air leaks.

Turn on the system:

Turn the system back on and allow it to run for a few minutes to ensure proper airflow.

Regular maintenance:

As with the filters inside the MVHR unit, regular maintenance is crucial for the proper functioning of in-line filters. Clean washable filters every 3-6 months, depending on usage, and replace disposable filters according to the manufacturer's recommendations.

In summary, cleaning in-line filters requires additional effort but is crucial for maintaining the air quality in your home. Identifying the location of the filter, turning off the system, removing the filter, cleaning the filter and ductwork, reinstalling the filter, and turning on the system are the key steps to follow. Regular maintenance is also important for the longevity and efficiency of the system.
