Ventilation filter guide

Are you allergic?People who suffer from allergies can benefit a lot from a ventilation system. The most common kinds of pollen particles are around 20-80µm, but some pollen particles, for example from forget-me-nots, can be as small as 2.5µm.If you choose an F7 filter for the intake, 99% of particles larger than 2.5µm will be removed.Particle size of other allergensFungus particles are around 2-20µm.

If the filters get blocked, it takes a lot of energy to force the air through, and some particles might be forced through.You can connect a filter alarm to the controls to remind you when to change it. To keep everything working optimally, you can also enter into a service agreement to have the system cleaned and the filter changed every six months.Need a filter?
