Best Air Purifiers

Best air purifiers offer the best air purification results combined with best overall features.

The discussion as to which air purification methods result in best overall results is still ongoing, but there are several measures that can be compared.

One such measure is the percentage of particles filtered from the air and the effectiveness in terms of how small particles the filter can capture.

If this measure is used, the HEPA (High Efficiency Particulate Air) filter using air purifiers set very much the standard. The best HEPA purifiers can clean up to 99.97% of the particles in the air of as small as 0.3 micron in size.

However, there is a technology titled ULPA (Ultra Low Penetrating Air), which removes 99.999% of airborne particles as small as 0.1 micron. Based on this measure, these purifiers are the best.

Best Air Purifiers - ULPA and IQAir HealthPro

There is an increasing number of air purifier products that feature the ULPA technology.

However, these are expensive purifiers and are mostly used by companies and organizations (such as hospitals) that need the best in air cleaning technology.

Available air purifiers with ULPA technology include:

Bionaire UA0860
Bionaire UA2560

Finally, in addition to the ULPA products, you may want to take a look at IQAir HealthPro air cleaner. According to some sources, this brand was chosen by the Hong Kong Hospital Authority to be used with the control of the SARS outbreak.

According to resellers of this system, the HealthPro actually delivers clean air that is in the range of hundred times cleaner that that of most conventional HEPA and ULPA air cleaners.
