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

Air Purifier: An air purifier is best described as a device designed to eliminate pollutants from the air in any part of any building. Pure air is proven to be good for those that suffer from asthma and those susceptible to allergic reactions. If you're considering purchasing an air filter you may find the following helpful.

The Benefits of Using 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 Type of Air Purifier do You Recommend?

Different air filters do different jobs so it's paramount that you understand your personal air purifying needs. Where you need to filter out large particles in the air, then a HEPA filter would be your first choice. These can remove over 99% of 0.01 to 0.3 micro-metre particles. They are, however, unsuitable for particles less than 0.01 micro-metres. Use a pre-filter before the HEPA filter for when you need to eliminate very fine particles.

Air particulates of 0.3 micro-metres or more are best extracted with an HVAC at MERV 13 or larger. If you are wanting to extract powerful chemicals and strong odours then it is suggested you use activated carbon filters and then follow this up with a HEPA filter to remove the smallest particles. Moulds, bacteria and viruses should be removed with photo-catalytic oxidation (PCO) - this is quite often incorporated with HVAC systems.

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 Shopping for 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 unreservedly recommends air purifiers, air cleaners or air filters for indoor use - especially where there are allergy or asthma sufferers. If you are seeking further information regarding this topic then I recommend The U S Environmental Protection Agency and its Science Advisory Board publication Indoor Air Quality.
