Do you have a WTW unit hanging in your home or building? Then you should make sure that you replace the WTW filters regularly. The heat exchanger filters filter fine dust and polluted air particles from the air flowing into your home through the heat exchanger. Thus, the heat exchanger filter ensures clean air in your home. It is therefore logical that after a while the heat exchanger filter is full of dirt particles through which no clean air can pass. Not only do dust and dirt particles collect on these WTW filters, if you don't replace them regularly, harmful mold can also begin to live there.

In this knowledge article, we take you through the do's and dont's when installing a bathroom fan, mechanical ventilation or heat recovery system (WTW) yourself. Of course, many of these tips you can also apply when connecting other, similar, fans. Let's start with one of the most frequently asked questions:
Air purifiers are increasingly popular, especially with the advent of corona. However, what you need to pay attention to when buying an air purifier is the extent to which the ioniser emits ozone. Ozone can be harmful to humans under certain conditions. What conditions these are, we explain later in this blog.
Fresh and clean air contributes to good health. Unfortunately, air quality has only deteriorated in recent years. A well-known air pollutant is particulate matter. Although you cannot see these particles with the naked eye, they can (seriously) damage your health. With a particulate matter (PM) meter you will gain insight into the amount of PM that is present in and/or around your home. In this way you will become aware of the air you breathe every day and you may be able to take measures to reduce the number of dust particles.
The main reason to ventilate is to positively influence air quality. Therefore, everyone has ventilated at some point or has indirectly come into contact with it. Some examples are: opening a window (blowing air), ventilating via window grilles or fans.
