Regular filter replacement is essential to maintain the efficiency of your MVHR (Mechanical Ventilation with Heat Recovery) unit, reduce energy consumption, and extend the life of your ventilation system. While changing filters is a simple task, manufacturers often provide only basic instructions, leading to common mistakes.
Coarse filters capture larger particles like dust and sand while ensuring low airflow resistance, quieter operation, and energy efficiency. Ideal for ventilation systems, they extend filter lifespan and protect HVAC components. CleanFilter Coarse filters offer premium materials, high dust-holding capacity, and certified performance for cleaner indoor air.
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.
Knowing the difference of the filtration classes according to the ISO 16890 may help you select the necessary filters according to your needs
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?
