What filter set protects against
Filter set includes 3 filters of different efficiency classes:
- Extract filter – G4 (Coarse 75%) – for MVHR protection
- Supply filter – G4 (Coarse 75%) – for indoor air protection (pre-filter)
- Supply filter – F7 (ePM1 55%) – for indoor air protection
This filter set follows the ISO 16890 standard for particle filtration efficiency.
The two G4 filters capture up to 75% 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 cleans the air extracted from your indoor space and protects the MVHR unit by reducing visible dust and general build-up in the ventilation system. This keeps the unit quiet, and extends your system’s lifespan. Meanwhile, the second one acts as a pre-filter on the supply side, capturing larger particles from incoming outdoor air before it reaches the main filter.
The F7 filter captures around 55% of very fine particles as small as 1 micron, 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
Vallox 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 Vallox, a trusted partner we’ve worked with for many years. By purchasing all products directly from them, we ensure authenticity and consistent quality. Vallox filters are designed and manufactured in Finland, adhering to high European production standards. With over 50 years of experience, Vallox is a leader in ventilation solutions, continuously innovating to improve energy efficiency, reduce noise, and enhance user convenience. Their commitment to quality is reflected in the use of certified materials and thorough testing, ensuring every filter delivers reliable performance and durability.
The F7 filter is made using Minipleat technology, a dense pleating method where the filter media is tightly folded and bonded with glue. This glue fixation keeps the pleats evenly spaced and stable, ensuring consistent filtration across the entire surface. Compared to standard pleat types, this design offers a larger effective filtration area, more uniform airflow distribution, improved particle capture, and a lower pressure drop.
On the other hand, the two G4 filters are made from a durable, fabric-like material designed to capture larger particles. The extract-side filter protects the MVHR unit from internal dust build-up, while the supply-side acts as a pre-filter, helping to prolong the lifespan and performance of the main F7 filter.
Choosing original Vallox filters ensures that your MVHR system operates according to the manufacturer’s stated technical data, maintaining both optimal air quality and energy efficiency.
