An M5 filter helps protect your ventilation system—especially the heat exchanger—from clogging, while also filtering out PM10 particles common in many European cities. Positioned between G4 and F7 filters, the M5 offers more effective filtration than G4 with lower energy use and a longer lifespan than F7.
Filters are classified by how well they trap particles, and F7 filters fall into the "fine filtration" category. These filters capture small particles (0.3-1 μm) to help maintain good indoor air quality, even in highly polluted areas.
G4 filters are effective at trapping medium-sized dust particles, sand, insects, lint, and even some larger pollen particles. They provide sufficient filtration to keep ventilation systems running smoothly and cleanly.
Original filters often cost up to €40-50 and also need to be replaced 2-4 times a year. But is it really worth overpaying for original filters when there are cheaper alternatives? You can save money by choosing a high-quality analogue filters.
Customers often complain about frequent filter changes. Especially if they use original filters, which cost 2-5 times more. So more frequent filter changes can cost an extra €30-100 per year. Why does it happen?
Many people who change filters for the first time are often surprised to learn that a recuperator needs 2 filters - after all, it needs to filter the air from outside, doesn't it?
AHU filters often travel a long way to the customer. It is therefore important to protect them from possible contamination during this time. Are the filters you have just ordered and received really clean?
