Overview of Home Air Purifiers
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.
The second hand smoke produced by cigarettes or other smoked substances can be greatly reduced by using an air purifier. Thankfully, the use of air purifiers goes far beyond just smoke. The vast majority of allergens can be removed from the air through the use of these devices.
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.
There are many techniques that are used to eliminate contaminants from the air. Some of them are fairly simple, but others are quite high tech. No matter which method you choose, you can be sure that your air will be much cleaner after it has been filtered than before.
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.
Those who would greatly benefit from the other techniques are those who are especially prone to getting sick from viruses and bacteria. Techniques like germicidal irradiation blast viruses with specific wavelengths of rays that completely destroy them. Filters are often ineffective because most viruses are not big enough to be caught by them.
Even though filters do not use any advanced technology, they are still quite effective. Most filters can remove 98% to 99.9% of airborne contaminants, as viruses and bacteria make up very little of the total contaminant ratio.
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.
