Air filters

Air filtration is the silent component of any ventilation system — it makes no noise, consumes no power, but determines the air quality breathed by the people in the ventilated space and the service life of the equipment in the system.

The Air Filters range on ventilation.ro covers all types and filtration classes used in residential, commercial and industrial ventilation, from AHU intake filters to mobile dust and gas capture units for production halls.

Installed in ventilation systems, air filters capture suspended particles — coarse dust, fine particles PM2.5, pollen, mould spores, bacteria and allergens — before air enters the ventilated space or the ventilation and air conditioning equipment. Filtration quality directly influences occupant health, installation cleaning frequency and the service life of fans and air handling units.

The filtration class defines efficiency and must be selected according to the application: G3-G4 filters capture coarse dust and protect equipment, M5-F6 filters capture medium particles including some allergens, F7-F9 filters capture fine PM2.5 particles and are recommended for offices, schools and spaces occupied by allergy sufferers, and HEPA H13-H14 filters capture over 99.95% of particles, including biological agents, for medical and pharmaceutical applications.

Our range includes compact filters for limited-space equipment, cassette filters with a rigid frame for air handling units (AHUs), filter boxes for direct duct mounting, activated carbon filters for retaining gases, odours and volatile organic compounds (VOCs), and modular filter units for industrial installations with high airflows and multi-stage filtration. Replace filters at the recommended intervals — a clogged air filter reduces airflow and can become a source of biological contamination.

Choosing the right filtration class:

• Compact filters — panel compact for small AHUs
• Cassette filters — Z-Line G4 for AHU filter banks
• Duct filter boxes — for circular ductwork, G4 included
• Activated carbon filters — frames + granules for odour elimination
• Modular filtration units — complete >99% filtration for industrial production
