House air purifiers are essential in keeping harmful allergens at bay. However, the matter of choosing which one to get necessitates a lot of consideration and research. What is there to know about house air purifiers anyway?

House air purifiers are devices which reduce the concentration of pollutants from the air inside your home. They are touted to be especially beneficial to those who suffer from allergic rhinitis and asthma. Users may also point out that another benefit of having indoor air purifiers involves the frequency of the need for household cleaning.

When going out to purchase house air purifiers, some things you may want to check out in a product are the kind of air purifier it is, the kind of HEPA filter used in it, the use of ultraviolet rays, its ozone byproduct, its noise level, and frequency of filter replacement.

There are several types of indoor air purifiers. First, you have the filter-based products which physically capture particles as they are air is forced through the filter. The best quality filters are the HEPA ones, which can eliminate at least 99.97% of 0.3-micrometer particles. There are also indoor air purifiers that make use of activated carbon, which can absorb volatile chemicals from the air. However, they usually function best alongside HEPA filters as they are not very good at filtering large particles. Other house air purifiers use photocatalytic oxidation and instead of filtering the air, sterilize it of mold, bacteria and viruses. Like the carbon ones, these indoor air purifiers are most effective when coupled with a HEPA filter. Another type of house air purifiers is the negative ionizer, which draws particles into the machine with the use of electrically charged ions. The particles are then ionized themselves and, negatively charged, they are sent back into the room where they are attracted to the positively charged items in the room, such as the walls and furniture.

The particles stay on these surfaces from which they must be immediately vacuumed or they would lose their charge and float back into the air. There are also indoor air purifiers called ozone generators, which produce the strong gas to clean the air by oxidizing other chemicals in it. Ozone is dangerous to the health, so house air purifiers that actually make use of this gas to function and not only produce it as a byproduct are not recommended.

Each of the indoor of air purifiers has its advantages and disadvantages. Manufacturers, however, are constantly coming up with new technologies to make their products more beneficial and to diminish any of the negative effects they may presently have.
