How the products work

Air Purifiers draw air into the unit using a fan. In some models, the air first passes through a washable pre-filter, which traps larger airborne particles. Then, the air passes through a high-efficiency True HEPA or HEPA-Type filter, which captures airborne particulates as small as 0.3 microns.

Bionaire air purifiers offer up to 99% (HEPA-Type) to up to 99.97% (True HEPA) particle filtration. Pure, filtered air is then quietly dispersed back out into the room by a powerful three-speed fan.

To enhance effectiveness, some air purifiers come equipped with an ioniser option. The ioniser setting releases negatively charged ions into the air, which join with small positively charged particles such as dust, dander and pollen to form larger particles that are more easily trapped by the HEPA filter.

With proper maintenance, regular use of an air purifier will help rid your home of airborne pollutants, resulting in better air quality and a more healthful home environment – enhancing personal comfort and well being.

The size of airborne particles that an air purifier can capture is measured in microns. A micron is approximately 1/25400th of an inch. Particles that are 10 microns or less are not visible to the naked eye.
