Air quality is one of the top ten factors determining how long we will live, and so air cleaners, otherwise known as air purifiers, are becoming increasingly popular. They will be more important as our homes need to become more sealed to conserve energy. Also, there is a misconception that they are only needed in…
If you are looking for an air purifier to improve your air quality, everyone knows they should buy one with a true HEPA filter. So it seems straightforward, but the term CADR keeps coming up. What is it and why does it matter? On the whole, the CADR, the clean air delivery rate, is the…
We live in an age when unfortunately, air pollution is increasingly being recognized as a problem.

Air purifiers are essentially consist of a fan pushing air through a true HEPA filter in an enclosure. So it is quite right to ask why are air purifiers so expensive? Obviously, the fan, motor and the control circuitry is relatively cheap to manufacture. Although there is quite a lot of research and development that…
Particle pollution is very strongly linked to health outcomes and is the 9th most common cause of death in the U.S. Forest fires are a particular problem in the western U.S. and the burning of fossil fuels in the eastern U.S. The smoke from both contains chemicals but also fine and ultrafine airborne particles. In…
