There are two common types of air purifiers that can remove some or all of the disease and allergy-causing particles in the air: mechanical filters—the most effective are classified as High Efficiency Particulate Air filters (HEPA filters)—and electrostatic precipitators.

Air purifiers depend on its types. HEPA filters are made out of very fine glass threads with a diameter of less than 1 micron. By comparison, a human hair has a diameter of about 75 microns. The fine glass threads are tangled together and compressed to form a filter mat. Because the individual threads are so microscopic, most of the mat consists of air. The openings in the mat are very small, generally less than 0.5 micron. HEPA filters will collect particles down to 0.3 microns in diameter. Even though the filter may only be 0.10 in wide, it would consist of 2,500 layers of glass threads.

Design of an electrostatic precipitator is considerably more complex. Home electrostatic precipitators usually are designed to have two components, an ionizing component and a collecting component. The collecting component consists of a series of parallel steel plates—half are grounded and half carry a positive direct current voltage—thus alternate plates are either positively or negatively charged. The ionizing unit consists of thin wires strung between a separate set of grounded steel ionizing plates parallel to, and set in front of, the collector plates. The positive charges in the wires induce a flow of electrons between the wires and the adjacent ionizing plates. Because there is a very high voltage on the wire, electrons are pushed toward it by an acceleration of around 1,000 times the acceleration of gravity, which accelerates the electrons to very high velocities.

Alpine repair air purifier provides numerous benefits:

1. Removes airborne contaminants and allergens.
2. Removes odours
3. Removes dirt and dust to make breathing and cleaning easier
4. When your system stops providing these benefits then it is time to get it repaired.
