The benefits of air purifiers are immense to anybody that uses one. For those with allergies or asthma, the difference that an air purifier makes is astounding and very important.

Air purifiers are especially helpful in drastically reducing or completely eliminating second hand tobacco smoke too. In addition, when allergens come around in the spring, the air purifier will remove virtually all of them from the air inside your house.

There are dozens of potential allergens that are waiting to attack you within your own home! In fact, too many of these allergens and contaminants can lead to serious diseases.

Air filters are also capable of removing almost all viruses and bacterial airborne contaminates. Various processes may be used to remove the different kinds of contaminants in the air. The most common type of purification technique is the size-exclusion filter, but there is also activated carbon, ionizer purifier, photocatalytic oxidation, and liquid ionizer methods.

The latter techniques are quite complicated and are more difficult to understand than the filter. However, just because they are more complex does not mean they are necessarily more effective, and regular filters can do the job for the majority of homeowners.

Due to the size of viruses and bacteria, you need more than just a filter to eliminate them. Methods such as photocatalytic oxidation are effective at killing viruses because they utilize principles that are not dependent on size. Therefore, no matter how small the viruses are, they will still be killed.

Filter based air purifiers are one of the most popular purifiers available in the market today at extremely reasonable rates. These purifiers physically trap the airborne contaminators through the filter. Air purifier filters have the capacity to remove 99.97% contaminates from the air.

The two types of basic filters to choose from are HEPA and MERV. HEPA is sensitive to particles as small as .01 micrometer while MERV is sensitive to larger particles. A HEPA filter is usually placed behind a conventional filter that cleans the coarser impurities. This helps the HEPA filter to remain clean and last longer. The filter based air purifier should be arranged in such a way that no air bypasses the filter. HEPA does not emit ozone or any other detrimental byproducts. Although the confining rate of MERV filters is less than HEPA filters, an air system at the center can move considerably much more air in an equal period of time.
