Double The Quality Of Your Home Air - Use An Air Purifier.

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.

What are the Benefits of Air Purifiers?

Relief for those who are susceptible to air-borne allergens - including dust, pet hair, pollens, mould, dust mites and smoke particles. House cleaning is reduced due the amount of dust it will remove from the air. Low energy use and electromagnetic emissions mean a safer environment. Which Type of Air Purifier is Right for Me?

What Air Purifier Should I Choose?

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 operate with charged electrical surfaces to bond to air impurities. These are very effective for large size homes, however, they do emit small amounts of ozone which is environmentally unfriendly so they are much less popular. A further suggestion for larger full size houses are Ozone Generators - these are excellent for removing strong odours that are not easy to remove with other types of air filters. They generate large amounts of ozone gas and are only suitable in unoccupied properties.

What to Look for When Shopping for an Air Purifier?

Check to ensure that the air filter does not emit any hazardous gas by-products, listen to how quietly it operates, check how regularly you need to replace the filters, monitor power consumption and make sure the unit is visually appealing. Most air purifiers generate very low levels of ozone gas and, with excluding Ozone Generator filters, are reliably safe to use. Do not buy an air filter that is described as HEPA-type, HEPA-like or 99% HEPA as these are not the genuine article.

U S Consumer Reports recommends air purifiers, air cleaners or air filters for your home and your office - particularly where people experience allergies or asthma. If you're looking for more detailed information on this topic then I unreservedly recommend the U S Environmental Protection Agency and its Science Advisory Board directive called Indoor Air Quality.
