A properly functioning ventilation system is essential for a healthy and comfortable indoor climate. In a home with an MVHR unit (mechanical ventilation with heat recovery), the filters ensure that dust, pollen and other contaminants are removed from the incoming air. Over time, however, these filters become dirty and need to be replaced to keep the ventilation system operating at its best.
Fortunately, replacing MVHR filters is usually a simple task that you can do yourself. By doing this regularly, your ventilation system will continue to operate efficiently, the air quality in your home will improve, and you will prevent dirt from building up inside the system. In addition, replacing the filters on time can help keep energy consumption low and extend the lifespan of your MVHR unit. But how exactly do you replace an MVHR filter? And what should you look for when choosing the right filters for your system? In this article, we explain step by step how to replace MVHR filters and share practical tips for maintaining your ventilation system properly.
Do you have an MVHR unit installed in your home or building? Then it is important to check your MVHR filters several times a year and replace them when necessary. MVHR filters ensure that fine dust and polluted air particles are filtered from the incoming air before it enters your home through the MVHR unit. In this way, the filters contribute to a healthy and clean indoor air quality.
Over time, however, MVHR filters become contaminated with dust and dirt particles. As a result, less clean air can pass through them and your ventilation system operates less efficiently. If you do not replace your MVHR filters regularly, bacteria and mould can also develop on the filters.
Good and important to know: Do you live along a busy road or is there a lot of construction taking place in your area? If so, your MVHR filters can become clogged and contaminated more quickly. Therefore, check your MVHR filters at least every 3 months and replace the filters of your MVHR unit at least twice a year. Are your MVHR filters visibly dirty or do they appear black from dust and debris? Then it is important to replace them immediately. It is therefore wise to always keep a few extra MVHR filters in stock. This prevents your ventilation system from spreading polluted air throughout your home and helps keep the indoor air quality optimal.
Yes, an MVHR filter in your MVHR unit is easy to replace yourself. Replacing an MVHR filter usually takes only a few minutes and ensures that your ventilation system continues to operate optimally. Clean filters are important for good indoor air quality and also help keep the energy consumption of your ventilation system low.
However, make sure you know which MVHR filters are suitable for your MVHR unit. There are three different types of MVHR filters: filters with a wire frame, filters without a wire frame, and panel filters.
It is important to always choose the correct filter that matches your type of MVHR unit. Later in this blog, we explain how you can easily check which MVHR filters you need. Make sure that your MVHR unit is not switched off longer than necessary. Only during maintenance, such as when replacing the MVHR filters, is it advisable to temporarily turn off the system.
There are different types of filters used in mechanical ventilation with heat recovery (MVHR) units. These filters are divided into different filter classes, depending on how fine the particles are that they filter from the air. The most commonly used MVHR filters are:
MVHR filters are designed for specific brands and types of MVHR units (mechanical ventilation with heat recovery systems). Each manufacturer uses its own filter dimensions, such as length, width and thickness. Which MVHR filters you need therefore always depends on the brand and type of ventilation system installed in your home.
To make sure you order the correct MVHR filters, it is best to check the nameplate of your MVHR unit. This plate shows exactly which brand and model ventilation system you have. By using this information, you can avoid ordering MVHR filters that are too large or too small and ensure that the filters fit properly in your MVHR unit.
You may have heard of it before: the new ISO 16890 filter standard. The old filter classes such as G3, G4, M6 and F7 are gradually being phased out and replaced by this new international standard for air filters. The ISO 16890 standard indicates more precisely what percentage of different dust particles a filter can capture. This allows you to better see how effective an MVHR filter is at filtering fine dust and other pollutants from the air. The higher the percentage and the smaller the ISO ePM value, the better the filter performs.
Would you like to learn more about this new regulation and what it means for your MVHR filters? Then also read our article: New regulations for MVHR filters: ISO16890.
Are your MVHR filters due for replacement? Then it is often also a good time to clean the ventilation valves in your home. These valves collect dust and dirt over time, which can reduce the airflow. You can easily clean the ventilation valves by carefully removing dust and dirt from them. Make sure you remember how far the ventilation valves are opened before removing them. After cleaning, place them back in exactly the same position so that the ventilation system continues to function properly.
Your MVHR unit itself also requires periodic maintenance. It is recommended to have the MVHR installation cleaned by a specialized company and not attempt to do this yourself. Professional cleaning of the MVHR unit is generally recommended once every 7 to 8 years, depending on your living situation. For example, if you live near a busy road, an industrial area or a construction site, more frequent maintenance may be necessary. Once again: a well-maintained MVHR installation and clean MVHR filters are important for a healthy indoor climate and good air quality in your home. By regularly checking and maintaining your ventilation system, your home will remain optimally ventilated.

MVHR Never blow out filters with a compressor. If done carelessly, you may damage the filter material or blow it out of the frame.
Never wash or rinse MVHR filters with water, soap or similar products. This changes the progressive structure of the filter, causing it to lose its effectiveness.
Never place a pollen filter in the exhaust. This creates more resistance and provides no benefit because this filter is only intended to keep coarse dust particles away from the heat exchanger. This air is discharged outside anyway.
