What filter set protects against
Filter set includes 2 filters of different efficiency classes:
- Extract filter – G4 (Coarse 60%) – for MVHR protection
- Supply filter – F7 (ePM10 60%) – for indoor air protection
This filter set follows the ISO 16890 standard for particle filtration efficiency.
The G4 filter captures 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. It's designed to clean the air extracted from your indoor space, helping to reduce visible dust and general build-up in the ventilation system. This lowers energy consumption, keeps the unit quiet, and extends your system’s lifespan.
The F7 filter captures around 60% of particles that are 10 microns or smaller, including bacteria, smog, tobacco smoke particles, combustion dust, spores, and wildfire smoke particles. It helps clean incoming outdoor air before it enters your premises, improving indoor air quality and protecting your health.
Usage and maintenance
Salda recommends replacing the filters every 3-6 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 Brink, a long-established ventilation specialist based in the Netherlands. With over a century of experience and a strong focus on innovation, Brink is known for producing reliable, energy-efficient air handling systems. Both their ventilation units and original filters are developed and manufactured in-house at their facility in Staphorst, ensuring full compatibility and dependable performance. The production process meets rigorous European production standards, and each original filter is thoroughly tested for airflow efficiency, filtration capacity, and long-term durability.
The G4 panel filter on the extract side is made using Z-line technology, featuring folded filter media mounted in a cardboard frame. Such design increases the filtration surface area, improves particle retention, ensures a more uniform airflow distribution, and maintains a low pressure drop.
The F7 material filter on the supply side is constructed with a durable galvanized wire frame that resists moisture and deformation, ensuring long-term structural stability. The filter media is made from premium-quality non-woven synthetic fibres - safe, resilient, and highly effective at capturing coarse airborne particles.

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.
- Check the label on the unit itself, which usually displays the manufacturer and model number.
- Contact your installer or the developer/builder of your property for details.
- Measure the width, length, and height of the filter, then use these measurements to browse our online shop. Our system will suggest the correct recuperator filters for your unit.
