New F7, G4, Activated Carbon, and Cone Filters available now
24 Nov 2025
At 5Merchants, we always look forward to new product launches and sharing those with you. We have just launched four new filter products that are easy to install, provide excellent filtration for home ventilation units, and are more cost effective than other versions.
G4 and F7 filters
The G4 and F7 filters are designed for the Zehnder ComfoAir ventilation units Q350, Q450 or Q600, and the F7 CA180 filter is designed for the smaller Zehnder CA180 unit. Here are some key features:
- Easy tab for quick replacement
- Sealing flaps to prevent air bypass
- Manufactured to ISO ePM1
- F7 and G4 Dimensions: 50 x 15.5 x 2.5 cm
- CA180 F7 Dimensions: 23.5 x 3 x 12.5 cm
Filters should be inspected monthly and given a light vacuum to remove dirt and dust, and replaced every 6 months to prevent blockages.
DN125 cone filters
Our cone filters are for the Zehnder DN125 exhaust valves, which are generally used for kitchen and bathroom exhaust. Highlights of this product include:
- Two-layer filtering material which provides less air resistance and therefore less energy consumption
- High filtration levels (dust absorption)
- Long filter life
- Machine washable
- Dimensions: 17 x 21 x 2 cm
Activated carbon filters
Our F7 Activated Carbon Filters suit the Zehnder Q350, Q450 or Q600 ventilation unit as well. These filters provide the same benefits as the standard F7 filters, but with the added benefit of activated carbon to reduce exterior smells, harmful particles, and pollution from entering the building.
- Easy tab for quick replacement
- Sealing flaps to prevent air bypass
- Manufactured to ISO ePM1
- Dimensions: 50 x 15.5 x 2.5 cm
