It forces water through the patented Claryum system — a combination of activated carbon, catalytic carbon, ion exchange, and mechanical filtration — to remove up to 99 percent of 77 different ...

a filter must meet stringent standards in terms of what it can capture from the air that passes through it. This type of pleated, mechanical filter can be effective against a wide variety of ...

4. The types of filters used by air purifiers The air purifiers we recommend use mechanical filtration, meaning that their filters physically trap the pollutants that pass through them.

Mechanical air filters work by trapping particles from the air onto the filter. High efficiency particulate air (HEPA) filters are a type of high efficiency mechanical filter. While mechanical ...

And they can be expensive to maintain. Mechanical filters need to be replaced every six to 12 months; they can cost upward of $200 per filter but typically cost no more than $80. Activated carbon ...

2 Comparing CADR performance of Blueair models with mechanical and electrostatic filtration vs same models with only H13 HEPA mechanical filtration. 3 When similar CADR was measured, Blueair ...

But mechanical filtration alone does not provide enough protection. One solution is to introduce an electric field to give the filter medium an electrostatic charge, which facilitates ultrafine ...

This also benefits the environment. Electrostatic adsorption is an important complement to mechanical filtration for high-efficiency air filtering in the use of face masks. However, the ...
