A fresh air system (also known as an Energy Recovery Ventilator or ERV) is an independent indoor air replacement and purification circulation system. It exhausts polluted indoor air while simultaneously drawing in outdoor fresh air, which is then filtered, sterilized, and passed through an energy exchange core before being supplied indoors.Simple understanding: If an air purifier is "washing clothes," then a fresh air system is "opening the window for ventilation" — it truly solves the fundamental problems of indoor oxygen supplementation and pollutant removal.
Core Functions
Ventilation: Continuously supplies fresh air (oxygen) indoors while expelling stale indoor air (CO2, formaldehyde, TVOC, etc.)
Deodorization: Quickly removes unpleasant odors caused by various sources such as cooking smoke, cigarette smoke, and renovation smells
Dust Removal: Effectively removes respirable particulate matter including PM2.5, dust, and pollen through multi-stage filters (pre-filter, medium filter, HEPA)
Temperature Regulation: Recovers energy from exhaust air through the total heat exchange core, reducing indoor temperature loss and improving heating efficiency in winter and cooling efficiency in summer
Humidity Control: Removes excess indoor moisture, effectively preventing condensation on walls, furniture mold, and bacterial growth
Sterilization & Disinfection (Optional): Eliminates bacteria and viruses using technologies such as photocatalysis, UV light, or plasma, with a kill rate of up to 99.9%
