What filter set protects against
Filter set includes 2 filters:
- Extract filter – G4 (Coarse 75%) – for MVHR protection
- Supply filter – G4 (Coarse 75%) – for indoor air protection
This filter set follows the ISO 16890 standard for particle filtration efficiency.
The 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 filters the air extracted from your indoor space and protects the MVHR unit by reducing visible dust and general build-up in the ventilation system. Meanwhile, the other one cleans the outdoor air supplied into your premises, improving indoor air quality and protecting your health.
Atrea typically recommends using the same filter grade on both the extract and supply sides (G4+G4 or F7+F7). However, if you prefer a higher filter class for the supply side, we recommend purchasing an additional 2-pack of F7 filters, as they are sold separately. You can find them via this link.
Usage and maintenance
Atrea 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
These filters are manufactured by Atrea, a respected family‑owned company based in the Czech Republic. Alongside its main facility, Atrea coordinates production through branches and authorised partners across Europe, where they maintain strict oversight of product quality. Backed by over 30 years of engineering experience, Atrea designs its products with a focus on energy efficiency, incorporating advanced heat exchange systems, automatic climate control, and cutting-edge airflow technology. All products undergo thorough internal testing and meet stringent European performance and quality standards.
These panel filters are made using Z-line technology, featuring folded filter media bonded with glue and mounted in a cardboard frame. The glue fixation keeps it evenly spaced and stable, ensuring more uniform airflow distribution and consistent filtration across the entire surface. Meanwhile, the folded construction increases the effective filtration area, enhancing particle retention and a lower pressure drop.
Choosing original Atrea filters guarantees your MVHR system performs according to the manufacturer’s specifications, maintaining optimal air quality and energy efficiency.
