What filter set protects against
Filter set includes 2 filters:
- Extract filter – G4 (Coarse 60%) – for MVHR protection
- Supply filter – G4 (Coarse 60%) – for indoor air protection
This filter set follows the ISO 16890 standard for particle filtration efficiency.
The G4 filters capture up to 60% of coarse airborne particles that are larger than 10 microns, such as soil particles, large pollen grains, plant debris, insect wings, sawdust, sand and textile lint. One of them filters the air extracted from your indoor space and protects the MVHR unit; while the other cleans the outdoor air supplied into your home, improving indoor air quality and protecting your health. This helps reduce visible dust, lowers energy consumption, keeps the system running quietly, and extends its lifespan.
Usage and maintenance
Zehnder recommends replacing the filters every 6 months, to ensure optimal air quality and system performance.
However, replacement frequency may vary depending on factors such as:
- Air pollution levels (e.g. urban vs rural areas)
- Allergies or respiratory sensitivities
- Indoor pets or smoking
- Dust from nearby construction sites
If your system includes a filter change indicator, follow its alerts. Otherwise, check the filters visually – if they appear very dirty or clogged, it's time to replace them.
Manufacturing quality
This filter set is manufactured by Zehnder, a trusted partner we’ve worked with for many years. We purchase all products directly from them, ensuring authenticity and consistent quality. Zehnder has its manufacturing facilities in the Netherlands, France, and Switzerland, upholding high European production standards.
The filters are made using Z-Pleat technology, which significantly increases the filtration surface area by folding the material into multiple pleats. This pleated design not only improves particle capture but also reduces air resistance in the system, helping your MVHR unit operate more efficiently.
By using original Zehnder filters, you ensure that your MVHR system operates in line with the manufacturer’s stated technical data, maintaining both optimal air quality and energy efficiency.

Frequently Asked Questions
Frequently asked questions ordered by popularity.
Filter class refers to the size and amount of particles a filter can trap. The higher the classification, the more effectively the filter removes particles from the air.
For incoming outdoor air, it’s generally recommended to use higher-class filters. However, we always suggest following the manufacturer’s guidance and using the specific filter sets outlined in your unit’s eco-commissioning documentation.
For more information, take a look at our comprehensive guide to filter classes for heat recovery units.
It is recommended to change the filters in your HRV every 3 to 6 months, depending on how dirty they become. However, the key signs that your filters need replacing include:
- An increase in noise from the HRV
- A reduction in the amount of air being supplied or extracted
Smart HRVs with an electronic control panel and display screen show the volume of air supplied and extracted per hour.
For example, if a Zehnder ComfoAir Q350 HRV in a 140m² home operates at an optimal rate of 190m³ per hour but drops to 150–170m³, the filters should be replaced.
