There are numerous types of air purifiers so a comprehensive know-how about air purification technology is great for have, particularly if you are planning to get one but don’t know which one to choose.

•    Ionic Air Purifiers: Ionic air purifiers create charged particles (ions) and give off them in to the surrounding air. These ions merge with harmful particles (like dust) in the air, driving the impurities to cling to a close surface. Ion generators are the second most popular type of air purifiers, however they both emit ozone, a powerful lung irritant that is in particular dangerous for people with asthma along with other chronic lung diseases, both children, and the seniors.

•    Hepa Filter Air Purifiers: HEPA air purifiers work on the 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 and other airborne particles. HEPA was first a registered trademark, also now has evolved into a generic term for highly effective filters. The primary problem with the HEPA air purifier is basically you must periodically replace the filter. The leading benefit: If it’s HEPA certified, then you already know it works well. Not all HEPA filters are created equal. Size matters: the greater square feet of HEPA filter the more particulates it will likely be able to remove. The size, material, and construction of the particular filter media all play a role in the air purifier’s overall performance and may account for why one HEPA filter is more expensive than another.

•    UV Light Purifier: This is basically a sterilization method using ultra-violet light. The UV light needs to be at the right wavelength of which the best performing is 254 nanometers. Only at that wavelength the UV irradiation breaks the molecular bonds within DNA of organisms like airborne bacteria and viruses. This kills them or renders them harmless. What’s more, it destroys fungal spores and mold spores.

•    Ozone Air Purifiers: As soon as the term ozone air purifier is used, it is generally conveying an air cleaner that produces ozone to sterilize the air or objects inside a room. Ozone air purifiers release ozone (O3) into the air. This reactive oxidant is most effective against chemical gases, smells and bacteria but cannot eliminate particles and also other allergens. Even so, excess ozone can result in the formation of new pollutants and therefore these purifiers should be used properly.

•    Carbon Air Purifiers: Carbon Air Purifiers are reliable with gas, smokes and smells, although not as efficient with allergens, dust, and bacteria. Carbon air filters are comprised of microscopic exceptionally absorbent pores. They chemically react to the particles that move through them. Much larger particles are caught up in the many pores.

An air purifier filter will help you get rid of your home’ s unhealthy particles which are flying around in the air. However, you better carry out your own analysis to buy the best and suited for your family needs.
