An air filter is a machine that removes dust and other contaminants from the air.
Why use an air filter?
Both the U. S. Environmental Protection Agency (EPA) and the American Lung Association recommends air filtration for people with allergies and asthma.
Types of air filters
* The mechanical filters
- mechanical filters of air through a special screen that keeps the particles, including allergens such as pollen, pet dander and dust mites.
- mechanical filters also capture of irritating particles like tobacco smoke
- the use of electronic filters electrical charges attract each other and deposit systems allergens and irritants.
- hybrid filters contain elements of mechanical and electrostatic filters
- vapor filters remove odors and non-particulate pollution such as cooking gas, the gas emitted by paints and building materials, and perfumes.
- the gas phase of the filters do not remove allergens
- ozone generators are devices that intentionally produce ozone, which manufacturers claim clean air
- Ozone Generators are not recommended by the EPA or American Lung Association.

The first step in finding the most suitable for the air to assess your needs.
A crucial step of finding an air filter for your needs is to determine the reasons why you buy the air. For example, if your air filter, because you have allergies, you want a filter that a high percentage of efficiency. The higher the percentage, the more types of pollutants the filter trap.
The second step is to find the most appropriate air filter is to determine the nature of the air and the amount of square images that you want to clean your filter.
