How to Choose the Right Home Air Filter

Honeywell dates back to 1885, and produces thermostats, air cleaners, humidifiers, and more. All these filters have advanced technology and meet American Lung Association Health House guidelines. The three-stage filter system includes activated carbon, pre-filter and HEPA filter.

There are many different kinds of air filters available today, such as HEPA, standard, pleated, electrostatic and electronic filters. Generally these filters are located in walls, ceilings, furnaces, or in the air conditioner itself. Electrostatic filters use filter media, which use an electric charge to attract the dirt particles in the air.

The air is required to be pure and without dust in places like research laboratories where even a dust of 1ppm or 1 part per million could contaminate the environment and would cause a lot of effect in the research recordings. Pre-filters can be washed and be reused. A hepa air purifier that uses filters are good at capturing allergens, but lack the ability to trap smaller particles, like chemical gases, odors, smoke, etc. House air filters are very necessary in hospitals where patients suffering from wheezing and asthma have to be in a very pure environment free of dust, else their problem could aggravate. Things like foam, ruffled paper, fiber glasses are used as air filters.

The work of the air filter in an air conditioning system is to keep the cooling coils and air inside the home clean and free from all forms of air contaminants such as pet dander and ozone emissions. The standard air filters, which are made of spun fiberglass with cardboard frames, have the ability to remove 10 percent of the airborne contaminants. Because of their greater surface area with filter material folded back and forth like a paper fan, manufacturers assert that these filters can last between two to four months.
