This replacement filter set is designed to fit the ventilation unit precisely, using size 315x310x35 to ensure correct installation and stable airflow. The Minipleat construction provides consistent filtration efficiency across the entire surface area.
If two filtration classes are included, the higher class is used on the supply air side for fine particle capture, while the lower class is installed on the exhaust air side to maintain low pressure drop.
The recommended replacement interval is 6-12 months, depending on usage conditions and the ventilation unit manufacturer's guidelines. This filter is compatible with Compact P2, Combi 400 Polar Top, ensuring correct fit and reliable performance across all supported units.
ADVANTAGES OF FILTERS24:
Certified safety: Filters have passed tests according to REACH for over 250 harmful chemical substances.
Proven efficiency: Performance of filter verified in an independent laboratory according to ISO 16890 standard.
Free from carcinogens: Filters tested for TOF / PFAS particles and confirmed to be completely safe.
Filter material: Modern, synthetic two-layer filtering material which provides less air resistance (and therefore less energy consumption), high filtration efficiency levels (in the form of dust absorption), and a long filter life (involving low pressure drops).
Durable design: Built with a strong frame that resists deformation under challenging conditions. Material is glued to the frame and prevents air leakage.
Competitive pricing: Affordable rates and a large inventory of ready-to-ship filter sets.

WHY CHANGE FILTERS OVER TIME?
The producers recommend that filters be changes at least once or twice a year, at the beginning and end of the heating season. The interval also depends on the location and the intensity of ventilation.
Old and dirty filters lead to a pressure drop in the ventilation system and, as a result, the volume of fresh air inflow decreases, which worsens the indoor climate.
An old, dirty filter can contribute to the spread of mould in the ventilation system. (especially in humid climates), which can be a health hazard.
The new filter has the best air permeability levels and, as a result, savings can be made in electricity costs for the fan unit.
STORAGE AND DISPOSAL:
For long-term storage, keep in a dry place. Used filters can be disposed of with regular household waste.
