What is an air filter?

An air filter is a machine that removes dust and other contaminants from the air.

Why use an air filter?

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
* Electronic filters
  • the use of electronic filters electrical charges attract each other and deposit systems allergens and irritants.
* Hybrid filters
  • hybrid filters contain elements of mechanical and electrostatic filters
* In the gas phase 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
  • ozone generators are devices that intentionally produce ozone, which manufacturers claim clean air
