FAQ

A MVHR filter is a filter used in a heat recovery system (MVHR). Every MVHR unit has at least two filters, both of which have the same function: to purify polluted air. Only the purpose is different. Supply air is stripped of harmful substances so that you enjoy healthy indoor air, while filtering the extract air primarily aims to protect the heat exchanger. To ensure both clean indoor air and an optimally functioning ventilation system, it is important to replace MVHR filters on time.

A MVHR filter is essential for a MVHR unit. First of all, MVHR filters play a crucial role in effectively improving air quality by filtering pollutants from the air. In addition, these filters have a positive effect on the operation of the ventilation system. In fact, they protect against accumulated dust, giving the MVHR system a longer service life, and contribute to optimised airflow. This results in direct savings on unnecessarily high energy costs.

Choosing the right filter for an MVHR unit is a simple task. Make sure you choose a filter that is compatible with both the brand and the specific type of your MVHR unit. After selecting the suitable filter for your MVHR unit, you can choose from different filter classes. Each filter class represents a specific degree of protection against certain (fine) substances. Moreover, you have the option to choose between a Tops filter or an original filter.

By using high-quality materials that comply with the ISO 16890 standard, formerly known as the EN779 standard, Tops Filter deliver the same high quality as original filters. What makes the difference is the price. So with Tops Filter, you always choose quality (and affordable) MVHR filters.

A G3 filter, also known as a coarse filter, is designed to effectively filter larger dust particles from the air. Using a G3 filter reduces the presence of unwanted coarse dust particles in the home. If you want better protection from smaller dust particles, choose an M-class (medium filter) or F-class (fine filter) with higher filter efficiency.

A G4 filter, also known as a coarse filter, is designed to effectively filter larger dust particles from the air. Using a G4 filter reduces the presence of unwanted coarse dust particles in the home. If you want better protection from smaller dust particles, choose an M-class (medium filter) or F-class (fine filter) with higher filter efficiency.

An M5 filter, also known as a middle filter, is designed to effectively remove medium-sized dust particles from the air. Using an M5 filter reduces the presence of unwanted medium-sized dust particles in the home. If you want even better protection from small dust particles, opt for an F-class (fine filter) with higher filtration efficiency.

An M6 filter, also known as a middle filter, is designed to effectively remove medium-sized dust particles from the air. Using an M6 filter reduces the presence of unwanted medium-sized dust particles in the home. If you want even better protection from small dust particles, choose an F-class (fine filter) with higher filtration efficiency.

An F7 filter, also known as a fine filter or pollen filter, is designed to effectively remove the smallest dust particles from the air. Using an F7 filter reduces the presence of unwanted fine dust particles as well as bacteria in the home.

An F9 filter, also known as a fine filter or pollen filter, is designed to effectively remove the smallest dust particles from the air. Using an F9 filter reduces the presence of unwanted fine dust particles as well as bacteria in the home.

A pollen filter or F7 filter, named after the F7 filter class, is designed to effectively filter pollen (pollen) from the incoming air, preventing these allergens from entering the home. This is especially beneficial for people with allergies, as it reduces the likelihood of allergic reactions such as sneezing, itchy eyes and breathing problems. It also provides a high level of protection against other particles, such as dust, mould spores and bacteria, keeping the air quality in the home extra healthy.

An MVHR filter has an average lifespan of 6 months, however, this is highly dependent on the use of the ventilation system. With more intensive use, the filter will become saturated and worn out faster. If the filters have a dark-grey colour, contain a lot of dust or no longer feel solid, it is to replace them.

If MVHR unit filters are not replaced on time, they become worn and lose their effectiveness. As a result, the air is not filtered sufficiently, allowing pollutants to enter the interior rooms of the house. In addition, the MVHR system has to work unnecessarily hard, resulting in higher energy consumption than necessary and faster wear and tear on the system.

It is strongly advised against cleaning MVHR filters with a hoover or washing them with water or any other liquid. This can damage the structure of the filters, rendering them ineffective. If the MVHR filters are not working correctly, the MVHR system will also not function optimally. This can negatively affect the air quality in the house. It is recommended to replace dirty or worn filters to ensure an efficiently functioning ventilation system.

A cooker hood filter is placed in the exhaust system and contributes to healthy air quality in the kitchen. There are two types of cooker hood filters: metal filters (grease filters) and activated carbon filters. Activated carbon filters filter unpleasant odours and fumes from the air, while a metal filter mainly retains coarse grease particles. The grease filter is always placed before the carbon filter and is therefore the most visible filter.

A activated carbon filter is a type of cooker hood filter and its main function is to neutralise unpleasant odours, cooking fumes and cooking smells. Thanks to the use of active carbon, the filter attracts these annoying odours, preventing them from lingering in the kitchen. The carbon filter contributes significantly to improving air quality in the kitchen. To maintain this improved air quality, it is essential to replace the cooker hood filter on time.

A carbon filter plays a crucial role by adsorbing and purifying odours and fumes. Filters with increased activated carbon content have an improved adsorption capacity, allowing them to absorb odours and fumes more effectively. Combined with a grease filter, a carbon filter contributes to fresh and healthy air quality in and around your kitchen.

For the optimal choice of a carbon filter for your cooker hood, it is important to select a filter that is compatible with the specific brand and type of your cooker hood.

It is strongly discouraged to clean carbon filters with a hoover or wash them with water or any other liquid. This can damage the structure and material of the filters, rendering them ineffective. If the carbon filters do not work correctly, the extraction system will also not function optimally, leaving cooking odours and fumes in the kitchen and negatively affecting air quality. It is recommended to replace dirty or worn filters to ensure an efficiently functioning extraction system.

Cone filters are designed to be placed behind an exhaust valve. They purify the air discharged to the ventilation duct through the exhaust valve, protecting the exhaust duct and the ventilation motor. Thanks to their cone shape, these filters are easy to place over the drain valve.

Filter cloth, also known as filter mat, is a filter medium used in MVHR units or air conditioning units. These cloths are made of durable fibre materials that filter unwanted substances from the air, contributing to a clean and healthy indoor climate. Easy size adjustability makes filter cloths versatile.

Filter cloths are available in filter class G3 and G4. A G4 filter cloth filters more unwanted substances than a G3 filter cloth. Some filter cloths also contain active carbon. They then not only filter dust particles, but also neutralise and adsorb odours and gases. This effectively eliminates annoying odours.

A exhaust valve is an air valve used to exhaust air from an indoor space. The valve is designed to control the air flow towards the ventilation duct as well as to remove unwanted substances, such as moisture and odours, from the room. An exhaust valve makes an important contribution to creating a healthy indoor environment and regulating air quality.

The air supply or exhaust through ventilation valves is easily adjusted by increasing or decreasing the space between the centre piece and the rim. The larger this space is, the more air is supplied or removed to the room. It is important to avoid completely closing the valve at all times to keep the room well ventilated.

To ensure that your ventilation system continues to function optimally, it is advisable to clean the drain valve at least twice a year. This will prevent the accumulation of dirt particles in and around the valve. How to clean the ventilation valve:

Step 1: Carefully remove the valve from the ceiling or wall.
Step 2: Rinse the valve with lukewarm water and a soft cloth. Make sure the valve is thoroughly dry before replacing it.
Step 3: Put the right valve back in its original (!) place. This will prevent disruption of the ventilation system.

Did you go through these steps? Top(s)! The ventilation valves are now functioning optimally again.
