Itho Daalderop HRU G 225 / 275 + W 250 / 350 MVHR-filters

A MVHR filter is a filter used in an MVHR unit (heat recovery system). The function of an MVHR filter is to purify the incoming and outgoing air of harmful substances, transforming the air into clean and purified air. The filter contributes significantly to improving the air quality in the home. To maintain this improved air quality, it is important to replace MVHR filters on time.

Choosing the right filter for an MVHR unit is a simple task. Make sure you choose a filter that is compatible with 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 house brand Tops filter or an original filter.

A MVHR filter is essential for a MVHR unit. MVHR filters play a crucial role in effectively improving air quality by filtering pollutants from the ventilation system. These filters provide protection against accumulating dust, thus extending the life of the MVHR system. In addition, MVHR filters contribute to optimised airflow, allowing the ventilation system to operate in the most efficient manner. This results in direct savings on unnecessarily high energy costs.

By using high-quality materials and filters that comply with the ISO 16890 standard, formerly known as the EN779 standard, the house brand of Tops filters delivers the same high quality as the original filters. Despite this high quality, it is combined with an affordable and economical price. So you buy extra high-quality MVHR filters at a low price from Tops filters.

A pollen filter or F7 filter, named after the F7 filter class, is designed to effectively filter pollen (pollen) from the supplied 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. Moreover, it offers a high level of protection against other particles, such as dust, mould spores and bacteria, keeping the indoor air quality in the home extra healthy.

If you have only one pollen filter, the pollen filter is placed on the supply air side of the MVHR unit. This side can be recognised by the outside symbol (cloud, tree or sky) present on the unit. The reason for placement on this side is that this is where the supply air, including any pollen, enters the house. However, if you have 2 or more pollen filters, they can be placed on both the supply and exhaust side.

It is strongly discouraged to clean MVHR filters with a hoover or by washing them with water. This can damage the structure of the filters, rendering them ineffective. If the MVHR filters do not work correctly, the MVHR system will also not function optimally, which 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.

On average, an MVHR filter has a lifespan of 6 months, however, this strongly depends 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, the time has come to replace them.

For optimal operation of the ventilation system, it is necessary to replace the MVHR filters at least twice a year. With intensive use of the system or in a newly built house, it is recommended to change the filters more often. Therefore, regular inspection of the filters in the MVHR unit is essential, especially for the accumulation of dust or a dark-grey discolouration of the filters. As soon as this occurs, it is time to change the filters for new ones.

Replacing an MVHR filter is a simple task that is done within moments. Before you actually proceed to replace the filters, it is essential to remove power from the appliance or system by unplugging it. Next, look for the covers behind which the dirty and old filters are attached and remove them. Now insert the clean and new filters into the unit, plug the power back in, and the MVHR unit will automatically run through the start-up programme.

If the MVHR units filters are not replaced on time, they become worn and lose their effectiveness. As a result, the air is insufficiently filtered, allowing harmful substances to enter the interior 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.
