Buy Wolf CWL 300/400 Excellent Filter Set (525x185x5) online. Complete replacement filter set with two G4 filters included, designed for reliable air filtration in Wolf CWL 300/400 ventilation units with fast EU delivery.
What This Product Is
This filter set provides essential air filtration for Wolf CWL 300/400 Excellent ventilation systems.

This economical filter option maintains healthy indoor air quality while protecting your HRV unit from dust and particle buildup.
Filter Class Comparison
Understanding filter classes helps you choose the right filtration level for your needs:
- G4 filters capture medium-sized particles down to 10 μm, providing effective protection against dust, pollen, and larger airborne particles
- F7 filters capture ultra-fine particles down to 0.3 μm, offering superior filtration against fine dust, traffic pollution, and allergens
- The G4+G4 set is ideal for standard residential environments with normal air quality
- Consider upgrading to an F7 supply filter if you live in urban areas with higher pollution levels or if household members have allergies
For most homes, the economical G4+G4 configuration provides sufficient filtration while maintaining optimal airflow.
