What filter set protects against
Filter set includes 2 filters:
- Extract filter – G4 (Coarse 70%) – for MVHR protection
- Supply filter – G4 (Coarse 70%) – for indoor air protection
This filter set follows the ISO 16890 standard for particle filtration efficiency.
The G4 filters capture up to 70% 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 premises, 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
Paul 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 part of our carefully developed house brand, manufactured in the European Union by trusted manufacturing partners who follow our strict quality requirements. Our strong cooperation with production partners, combined with our own quality inspections, ensures reliable performance and consistent quality.
These panel filters are made using Z-line technology, with densely folded filter media mounted in a cardboard frame. Such design maximises the filtration surface area, enhancing particle retention and airflow efficiency. This kind of construction offers a larger effective filtration area, more uniform airflow distribution, improved particle capture, and a lower pressure drop.
