How the products work

Air Purifiers draw air into the unit using a fan. In some models, the air first passes through a 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® Replaceable HEPA-Type filter and HEPA-Type carbon filters are 99% efficient in removing particles larger than 2 microns in size passing through the filter.

To enhance effectiveness, some air purifiers come equipped with an Ionizer* option. The Ionizer 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 reduce airborne pollutants in your home, resulting in better air quality and a more pure 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.

Size Item

100 microns - The diameter of human hair
25 microns - Debris and other particles
10 microns - Heavy dust, spores from plants & pollen
5-10 microns - Skin flakes, moulds, pollen, average dust, pet dander
1-5 microns - Light atmospheric dust, dust mite debris
0.3 to 1 micron - Tobacco smoke, metallic fumes



*The ioniser's in Bionaire's appliances are compliant with regional regulations in that they product less ozone than the ozone emission standards set forth in the regional regulations. However, in high concentrations ozone can be harmful to birds and small pets. To prevent ozone build-up, we suggest using the independently controlled ioniser function in well ventilated areas
