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.
