New arrival: AirFree Air Purifiers that are filter & maintenance free

Thursday, October 26th, 2017

Hwee Seng Electronics launches in Singapore 6 models of air purifiers from AirFree. The air purifiers reduce ozone concentrations and destroy 99% of airborne allergens by burning microorganisms at the high temperature of a ceramic core.

The Lotus air purifier from AirFree, capable of covering 60 square metres of indoor space.

The purifiers are maintenance free as they do not use filters – as opposed to most HEPA-filter based air purifiers.

The heated air from the hot ceramic core is released back into the room through the top of the air purifier and cool air is sucked in through the air vents at the bottom of the air purifier because of convection currents.

As a result, the AirFree purifiers do not use a motor like in most purifiers that suck air through a HEPA filter.
