AIRFI filters

AIRFI filters

AIRFI ventilation unit filters ensure efficient supply and exhaust air purification while helping maintain optimal ventilation system performance. Regular filter replacement helps maintain high indoor air quality, reduces the amount of dust, pollen and other pollutants entering the premises, and protects ventilation unit components from contamination. Quality filters not only improve living comfort but also contribute to a longer service life of the ventilation system and more efficient energy use.

Compatible models:
  • Various AIRFI ventilation units
  • Residential and commercial ventilation systems
  • Models designed for standard filter sets
Filter classes:
  • G4 – for capturing larger dust particles, insects and other larger contaminants.
  • M5 – more efficient filtration of fine dust and improved indoor air quality.
  • F7 – high-efficiency filtration that captures pollen, fine dust and part of airborne pollution particles.
  • F7/AC – F7 class filter with an activated carbon layer that helps reduce unpleasant odours and gaseous pollutants.
How to choose the right AIRFI filters?

The most important factor when selecting new AIRFI filters is the exact filter dimensions. Before ordering, it is recommended to remove the old filters and check their length, width and thickness or consult the ventilation unit documentation. Even small dimensional differences can result in poor fit, air leakage and reduced filtration efficiency.

It is also important to evaluate the desired filtration level. G4 filters are suitable for basic protection against larger particles, M5 filters provide better fine dust filtration, while F7 filters are recommended for allergy sufferers and people living in urban or high-traffic areas. If you would also like to reduce incoming odours, smoke and gaseous pollutants, F7/AC filters with activated carbon are the ideal choice.

If you are unsure which filters fit your AIRFI ventilation unit, first compare the filter dimensions and determine the level of air filtration you require.

Why replace filters on time?
  • Ensures cleaner and healthier indoor air.
  • Maintains ventilation unit performance and energy efficiency.
  • Reduces strain on ventilation system components.
  • Helps prevent dirt accumulation in ducts and equipment.
  • Reduces the entry of outdoor pollution, pollen and odours.
