Air Purifier HEPA Filter

August 21, 2008

The air purifier HEPA filter is an air purifier that filters the air in the room where the machine is located. The air purifier HEPA filter has a filter and a fan to make the air circulate through the machine. This kind of air purifier is very effective, being capable of removing at least 99,97% of 0.3 micrometer particulates. However, people tend to point out noise levels as a disadvantage of air purification system. This machine is not a ozone generator like ozone air purifiers  or an ionic air purifier like air ionizer purifier . Some air purifier HEPA filter now use UV Lamps to sterilize the micro-organisms trapped in the filter, but the device is not an UV air purifiers . Air purifier HEPA filter has nothing to do with activated carbon air filters or hydroxyl radicals. This device just filters the air. The filters used on this machine can last several years. If the device is being used in dusty environments it’s recommended to use a conventional filter as a pre-filter, so the HEPA filter can last longer. It’s important to have in mind that this air purifier is not effective on odors or removing cigarette smoke. It doesn’t remove germs and viruses also.
