ALNOR filters

Filters for ALNOR ventilation units: maintenance and efficiency

High-quality analog filters are an essential part of your ventilation system, directly determining the efficiency of the unit and the microclimate of your home. Over time, ventilation unit filters inevitably become clogged with dust, pollen, and other environmental pollutants. To maintain optimal heat recovery and prevent system failures, it is recommended to change the filters regularly – every 3-6 months, depending on environmental pollution and usage intensity.

Clean and healthy indoor air

Timely replaced filters guarantee impeccable supply air quality. A clogged filter loses its efficiency and becomes a breeding ground for pollutants, while our newly manufactured filters, designed for various ALNOR HRU-PremAIR and other ALNOR series units, reliably capture even the finest particulate matter, smog residues, allergens, and mold spores, preventing them from entering your living spaces.

Lower electricity consumption

When ventilation unit filters get clogged, the ventilation system's fans have to work with a significantly higher load to push the required airflow through the resulting resistance. Regular filter replacement allows maintaining minimal air resistance in the system, so the ventilation unit consumes significantly less electricity and operates noticeably quieter.

Longer ventilation system lifespan

Clean filters prevent dust and other impurities from entering the unit itself and its electronic components. Investing in new filters helps avoid costly ventilation unit repairs or duct cleaning works in the future.

High-quality analog filters directly from the manufacturer

The analog filters offered in our e-shop are manufactured in the EU using only high-quality, certified filtering materials. All products are precisely designed to fully match the technical dimensions and aerodynamic properties of the respective ALNOR ventilation units, ensuring simple installation, complete airtightness, and reliable protection.
