What filter set protects against
Filter set includes 4 filters of different efficiency classes:
- 2 × G1 filters (Coarse 40%) – for capturing large particles and protecting the MVHR unit
- 1 × G4 filter (Coarse 75%) – for improved coarse-particle filtration and MVHR protection
- 1 × F7 filter – for fine-particle filtration and indoor air protection
This filter set is designed to provide several stages of air filtration. The G1 filters capture approximately 40% of coarse airborne particles, including larger dust particles, plant debris, textile fibres, insects and other visible contaminants. They help reduce dirt accumulation inside the ventilation unit and protect its internal components.
The G4 filter captures approximately 75% of coarse particles, including household dust, larger pollen grains, fibres, sand, sawdust and plant debris. This additional filtration stage helps keep the heat exchanger, fans and ventilation ducts cleaner, supporting efficient airflow and extending the system’s service life.
The F7 filter is designed to capture substantially finer airborne particles than the coarse filters, including fine pollen, mould spores, smog, combustion dust and smoke particles. It cleans incoming outdoor air before it enters your premises, helping improve indoor air quality and providing additional protection for people affected by allergies or respiratory sensitivities.
Usage and maintenance
To ensure optimal air quality and reliable ventilation-system performance, inspect the filters regularly and replace them when they become dirty or clogged. Under typical operating conditions, filters should usually be replaced every 3–6 months. 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 is time to replace them.
Manufacturing quality
This is an original Vallox filter set manufactured by Vallox for compatible Vallox ILMAVA ventilation units. Original filters are produced according to the ventilation-unit manufacturer’s technical requirements, helping maintain the intended airflow, filtration performance and energy efficiency of the system.
The set consists of frameless filter-material elements designed to fit the specified Vallox units correctly. Their synthetic filtration material provides dependable particle capture while allowing suitable airflow through the ventilation system. By using original Vallox filters, you help ensure that your MVHR unit continues to operate according to the manufacturer’s stated technical specifications.
