Large Coverage Area The BioGS SPA-421A air purifier will filter all of the air in a room up to 600 sq. ft. (or 780 sq. ft. for the SPA-582A) twice in an hour on the turbo setting.

Energy Efficient Energy Star Certified. Inexpensive to operate. Only consumes 7 Watts at silent speed.

Zero Ozone Emissions The BioGS air purifier emits ZERO ozone and is absolutely safe to use for asthma and allergy sufferers.

Ultra Quiet The heart of this air purifier is the Brushless Direct Current Motor, an innovative motor with inverter control that offers 5 different speeds of operation. When operating at low speed, the air purifier's motor barely makes a sound.

Superior Quality With a 5 years warranty on parts and labor and 24/7 technical support, the BioGS is one of the highest quality air purifiers you can find.

Four Stage Purification The unit includes a six stage purification system and an activated carbon filter to fight off odors. Our BioGS HEPA filter will trap and reduce 99.97% of particles that pass through the filter down to 0.3 microns in size.

Comparison between BioGS HEPA filter and typical HEPA filter
