The MVHR unit controls the system, but the filters do the real (dirty) work. Large amounts of polluted air pass through the ventilation system every day, where the dust particles are collected by the filters. Over time, these filters become saturated. The result? Air purification decreases and you are no longer guaranteed healthy indoor air. Do you want to enjoy clean air permanently and carefree? Then it is advisable to change the filters on time.

The replacement period depends on several factors, including the intensity of use and the amount of air pollution. For example, a filter in a house in a heavily polluted area will last less time than the same filter in a house close to the nature. In general, we recommend replacing the filters at least every six months; this is the lifespan of a filter in an environment with an average amount of air pollution. Check the filters in between to determine the level of pollution.

Basically, the same guidelines apply to newly built houses as to older houses, provided the work has been fully completed. Do you have a newly built house and is construction in progress in your neighbourhood? Then it is advisable to change the filters every 3 to 4 months. Due to construction, many (coarse) dust particles are released. Preferably choose a coarse filter during this period and check it between times to determine the degree of contamination.

Replacing the filters is an important step in maintaining the MVHR unit. It is also advisable to have a comprehensive maintenance carried out biannually and to have the ducts cleaned every 7 years. Looking for someone to help you with this?

Replacing a filter is easier than you might think. Although the steps may vary (slightly) from unit to unit, you should generally do the following:
Step 1: switch off the system completely by unplugging the power cord, unless the unit explicitly indicates that this is not necessary. It is unwise to remove the filters while the system is on.
Step 2: remove the covers giving access to the filters.
Step 3: remove the old filters and replace the new ones.
Step 4: replace the covers and restart the MVHR unit.
Step 5: go through the steps on your unit's screen to remove the filter notification (if applicable).

You place the pollen filter on the air supply side of the MVHR unit. This way, any pollen and other fine dust particles are filtered out of the air before being blown into the house. You can recognise the supply side by the outside symbol (e.g. cloud, tree or sky) on the unit or by the amount of dirt on the filter. The side with the dirtiest filter is the supply side.

Cooking, baking and frying... delicious! But often also quite polluting for indoor air. Not surprisingly, hood filters become saturated with odours and other particles over time. As a result, polluted air is not only discharged worse; the cooker hood also has to work harder. And that in turn costs extra energy. Replacing the cooker hood filter on time is therefore beneficial for your health, the climate and your wallet.

The replacement time depends on several factors, including the intensity of use and the type and number of (dust) particles to be filtered. Cooking, for example, has less impact on air quality than baking or frying. In general, we can say that a cooker hood filter has an average lifespan of 6 to 9 months. Some cooker hoods give an alert when it is time to change the filters. Does your cooker hood not have this feature? Then use your senses. Do you notice, for example, that odours linger longer or that fumes continue to circulate in the kitchen? Then it's time for Tops!

Changing an cooker hood filter is a quick and easy job. What exactly you need to do? That depends on the brand and type. Your cooker hood manual or instructions will tell you exactly how to change the filter.

To ensure optimal operation of the drain valves, we recommend replacing the cone filters at least twice a year. It is important to check the cone filters regularly, especially for accumulation of dust or a dark grey discolouration. Is this the case? Then it is time to replace the filters.

Carefully remove the drain valve from the wall or ceiling and slide the filter over the valve. Make sure the valve is replaced in the correct position, because of the adjustment of the air valve. Always check that the filter is tight before replacing the drain valve. It's that simple!

Most homes already have ventilation points. You usually find these in rooms with high humidity or a large number of dust particles. You can think of the toilet, the kitchen or the bathroom or bedroom. Do you want to install a new drain valve? Then place it in the most strategic location possible. This way, you ensure that polluted air is removed effectively.

It depends on the situation. You can adjust the air supply or exhaust by increasing or decreasing the space between the centre piece and the edge. The larger the space, the more air is supplied or removed. Do not close the valve completely; only an open valve can ventilate the space.

You can easily increase or decrease the space between the centre piece and the rim using the bolt at the back. Remove the valve, adjust it as required and replace it. It's that simple.

Replacing filters is generally a quick and easy job that does not require a mechanic. If, for whatever reason, it does not work, please give us a call. Our colleagues will be happy to help.
