Since the necessity of the situation of each allergy and asthma has different needs, it is a very difficult decision to choose the best air purifier. In addition to this tough task, it is a different allergen and the type of household pollution is removed in different ways. Below are some comparisons of some of the more popular types of air purifiers. .
Air purifiers with HEPA (high energy particle eye-catching) filters were originally developed for nuclear mission, dust and other airborne in commercial cleanrooms and very small holes with this paper or polymer sheet It becomes the material of circulation of air. Because the holes are so small, a lot of surface area is required due to the reasonable amount of air flow passing through the material. For this reason, the medium is always folded accordion or zigzag to get a lot of surface area in small areas. Which attracts smaller particles than HEPA filter holes are slightly larger to promote more air flow, but where the air is also filled with static electric thin rods and also through the mixing holes of the technology. The HEPA filter works well at home to capture particulates. The downside is that filters need to be replaced on a regular basis (5- to 6-month by 6 months by manufacturer). Before you buy, you also want the filter is good for the price of both the original unit and replacement filter How much air bypass filter, fa any HEPA unit review, efficiency (how much air filter ), Fan noise, filter life and price.
Ultraviolet air purifier uses ultraviolet rays. Ultraviolet rays of the right intensity destroy microbial DNA like bacteria and virus. A disadvantage of ultraviolet air purifiers is that they do not remove very few gas contaminants and air particles. It is then necessary to purchase an ultraviolet air purifier with one that combines with another type or another filter system.
Ion generators' air purifier is a small air purifier device that eliminates negatively charged ion flow. These ions meet the contamination of the microparticles and are attached due to electronic charging when the particles hit against something. These devices are used in US submarines and poultry industry to keep wing dust.
These air purifiers do what they say, but there are some very clear drawbacks. The wall behind the fine walls is also a device close to black. Secondly, it is a local area that must be a general fan. But do nothing It may be gas pollution and it is dangerous.
You can see the difference of the air purifier in just the above three cases. Study - comparison It is a specific case of a purifier even though shopping is necessary. Promotion excitement shake is judged by the customer himself, and it is said to be bad as a wrong air purifier.
