Are you considering an Air Purifier for the house? It may help to be familiar with the 5 most popular types so that you can make the best choice.

Hepa Filter Air Purifiers
HEPA air purifiers operate on the basic principle of filtration. HEPA is an acronym for “high efficiency particulate absorbing” or “high efficiency particulate arrestance”. This type of air filtration gets rid of over 99% of dust, mold, pollen, bacteria as well as other airborne particles. HEPA was initially a registered trademark, also now has developed right into a generic term for extremely effective filters. The primary disadvantage of the HEPA air purifier is that you have to periodically change the filter. The main advantage: If it’s HEPA certified, then you already know it works well. Not all HEPA filters are the same. Size matters: the more square feet of HEPA filter, the more particles it will be able to remove. The size, material, and construction of the particular filter media all play a role in the air purifier’s performance and may account for why one HEPA filter is more pricey than another.

Ionic air purifiers
Ionic air purifiers create charged particles (ions) and give off them into the surrounding air. These ions merge with harmful particles (like dust) in the air, driving the impurities to cling to a nearby surface. Ion generators are the second most popular type of air purifiers, however they both emit ozone, a strong lung irritant that’s in particular harmful for those who have asthma along with other chronic lung diseases, both children, and the elderly.

Carbon Air Purifiers
Activated carbon is treated with oxygen, opening up numerous pores in the carbon. There are lots of these little pores any particular one pound of activated carbon has a surface area of 60 to 150 acres. This huge surface area causes it to be well suited for absorbing gases and odors which is too small to be caught by a HEPA filter.

UV Light Purifier
This is basically a sterilization method using ultra-violet light. The UV light needs to be at the right wave length of which the best is 254 nanometers. At this wavelength the UV irradiation breaks the molecular bonds within DNA of microorganisms like airborne viruses and bacteria. This ruins them or makes them harmless. Additionally, it destroys fungal spores and mold spores.

Ozone air purifiers
Ozone air purifiers work like an ionic however it is best on odors. Ozone is a extremely reactive, unstable molecule that oxidizes everything it comes in contact with. The ozone purifiers result in chemical reaction which breaks down the pollutants, but the toxins turn into other pollutants, which is the problem with these machines. It truly is recommended that you simply run the equipment on low, and then available the window to release the ozone.

An air purifier filter can help you get rid of your home’s harmful particles which are flying around in the air. But you better carry out your own analysis to purchase the best and suited for your needs.
