Double The Quality Of Your Home Air – Use An Air Purifier. by Janie S Manne
Air Purifier: The definition of an air purifier is a machine whose sole purpose is to remove contaminants and other impurities from the air in any building. Scientists have proven that sufferers of asthma and those with reactions to air-borne allergens can unreservedly benefit from pure air in their immediate environment. The following is valuable information for those who are considering purchasing air purifiers.
The Benefits of Using Air Purifiers?
For those people who are prone to reacting to air-borne allergens – for example pet dander, various pollens, dust, mould spores, dust mites and even smoke particles, air filters offer dramatic relief. A quality air purifier will also help to reduce house cleaning due to the dust being extracted from the immediate air. Given that air purifiers are electrical, energy usage and any perceived danger of electromagnetic emissions, is minimal and does not pose any risk.
Which Type of Air Purifier is Right for Me?
Not all air purifiers will remove the same types of impurities so it is important to make sure you understand what your personal needs are. If trapping larger particles is important then you would need a HEPA filter. HEPA filters can remove 99% of 0.01 to 0.3 micro-meter particles. They are not effective for particles of 0.01 micro-meters or less. For particularly dusty rooms you should attempt using a pre-filter in front of the HEPA filter to arrest the very fine particles.
Air particles of 0.3 micrometers or more are better removed with an HVAC at MERV 13 or bigger filter system. If you are trying to filter volatile chemical mixes and pungent odours then it is recommended you choose activated carbon filters and then follow this up with a HEPA filter to extract the small particles. Mould, bacteria and viruses are more likely to be filtered through photo-catalytic oxidation (PCO) – these are often times integrated with an HVAC system.
Ionizer air purifiers are another type of air purifier. They use charged electrical surfaces or needles to attach to air impurities. These are very suitable for large size rooms. They are known to produce tiny amounts of ozone which, unfortunately, is not great for the environment. This makes them a less popular choice. Another option is Ozone Generators – these are ideal for removing strong odours that cannot be moved with other types of air filters. They generate large amounts of ozone gas and should only be used in unoccupied properties.
What to Look for When Investing in an Air Purifier?
Some of the things you should be looking for include making sure the air filter does not produce any unhealthy gas by-products, generates a low level of noise, how often the filters need to be replaced, level of power consumption and that the visual aesthetics are to your liking. Most air purifiers generate very low levels of ozone gas and, with the exception of Ozone Generators, are perfectly safe air purifiers to use. Be careful not to buy an air filter that is described as HEPA-type, HEPA-like or 99% HEPA as these are not true HEPA filters as far as govt standards are concerned.
U S Consumer Reports fully recommends air purifiers, air cleaners or air filters for use in any property – ultimately where there are people who suffer from allergies or asthma. If you wish to read further information on this topic then I wholeheartedly recommend the U S Environmental Protection Agency and its Science Advisory Board e-book called Indoor Air Quality.
