How Air Purifiers Can Double The Quality Of Your Home Air
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?
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.
What Type of Air Purifier do You Recommend?
Not all air purifiers will remove identical contaminants so you need to be very sure of exactly what your requirements are before you go ahead and shop for an air filter. If you are wanting to remove larger particles from the air then you would be advised to look for HEPA filters. These will remove more than 99% of 0.01 to 0.3 micro-meter particles, however, they are not effective at removing particles less than 0.01 micro-metres. Dusty rooms need a pre-filter before you use a HEPA filter so as to catch the 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 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 Investing in 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 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.
