The real reason why HEPA filters are so expensive is a combination of psychology and marketing. We value our health so much that we are often willing to pay a premium to protect it. Low-cost, low-end air purifiers often use air filters that look similar to HEPA filters, but don't provide the same level of filtration. These filters do not meet HEPA standards and may not capture smaller particles, such as microorganisms, including bacteria and viruses.
A genuine HEPA filter is 0.3uM (less than 1 millionth of a meter). It is important to remember that when looking for a cheap purifier, you should look for one with a HEPA or HEPA filter and one that you can find filters for without much trouble. True HEPA filters can effectively filter 99.97% of harmful particles in the air of the size of 0.3 microns and are tested according to HEPA standards set by the U. S.
UU. Budget air purifiers generally use a non-HEPA filter, have lower CADR ratings, produce high levels of noise, and generally have lower performance. Other brands that carry HEPA filters include Cabiclean, Homedics, VEVA, Isinlive, VIEWALL, Housmile, LifeSupplyUSA and Dyson. You can buy HEPA filters in household items, hardware stores, online, or directly from manufacturers via their websites.
If you want an air purifier with an odor eliminator, choose an appliance that uses HEPA filters with activated carbon. They often offer advanced-level HEPA filters with even finer particle size capture capability, more powerful & odor gas absorption filters, very large room size capacity, and different air cleaning technologies that are not available in mid-priced products. HEPA filters meet these standards and consist of a dense, fibrous material designed to collect particles in the air.
