Do you suffer from allergies? I know I do. I sneeze in summer, cough in winter, gasp in spring and choke in fall. All year long, they bother me. I tried everything. Allergy shots helped a little, improving my diet helped a little, but nothing did much until I got my air purification system.

There are several types of air purification systems. Mine is of the type called a hepa. A Hepa filter system has a high efficiency filter that traps particles which are blown through the system by a powerful fan. On top of this, it has an activated carbon pre-filter, which filters out molds, and odors. In most tests done by scientific organizations, this type of filter has rated the best of all of them. There's just no comparison. If you turn it on before you go to sleep, you'll be breathing clearly in the morning and be happy and healthy all day.

Another popular type of air purification system is the ionizer. This is a high tech solution, but people don't think it actually works that well. Basically, it takes all the air that goes through it and electrically charges it. This makes it cling to surfaces – carpets, furniture, bedding. Practically anything. It gets the dust out of the air, but does it by just making it settle in the room. Then you have to dust and vacuum, as well as frequently washing your bedding, or else the allergens are just as bad or even worse.

A washable filter air purification system is supposed to be a good choice, although I have never used one personally. In most respects it is like a hepa, running air through its filter and trapping dirt and dust inside. The problem with hepas is that you have to replaice the filter about every six months and the pre filter even more frequently – maybe every month or two. This can add up to a lot of money! But with a washable filter air purifier system, you never or almost never have to replace the filter. Just wash it, and it will be as good as new!

It is a good idea to read scientific reports and studies before buying an air purification system. There are so many on the market, and some are much better than others. They tend to be rated in several ways: how much space they can clean at once and, on average, how much they improve the air quality. So, if you have a small room, a small air purification system will work, but if your room is big, you might need a larger and potentially much more expensive one.
