Filters in the ePM10 class must capture at least 50% of PM10 particles (0.3–10 μm) during testing. For instance, a filter rated as ePM10 55% captures more than 55% of PM10 particles. The term "ePM" stands for Efficiency of Particulate Matter.
These filters are especially useful in areas with high PM10 pollution and can trap allergens like pollen, improving indoor air quality.
Filters in the ePM1 class must capture at least 50% of PM1 particles (0.3–1 μm) during testing. For example, a filter rated as ePM1 70% captures more than 70% of PM1 particles. The term ePM stands for Efficiency of Particulate Matter.
These filters effectively remove fine solid particles, ensuring healthier indoor air. They are the most efficient filters in the ISO 16890 classification.
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?
