What This Product Is
The Wolf CWL-2-225 Filter Set (400x215x5) is a compatible replacement filter set designed for the Wolf CWL-2-225 heat recovery ventilation system. This set filters both incoming supply air and outgoing extract air, maintaining clean indoor air quality while protecting your HRV unit from dust and particle buildup. The standard set includes two G4 filters, providing balanced medium-level filtration for both airstreams.
Filter Class Comparison
Understanding filter classes helps you choose the right filtration level for your needs:
- G4 filters capture medium-sized particles down to approximately 10 μm, including larger dust, pollen, and debris. Suitable for both supply and extract air in standard residential environments.
- F7 filters capture ultra-fine particles down to 0.3 μm, including fine dust, bacteria, and allergens. Recommended for supply air filtration when enhanced indoor air quality is required, particularly for allergy sufferers or urban locations.
For standard residential use, the G4+G4 combination provides effective filtration. For improved air quality, consider upgrading the supply air filter to F7.
