Written by Honeywell dates back to 1885, and produces thermostats, air cleaners, humidifiers, and more. They offer four types of air filters: Replacement Media filters, HEPA air cleaners, Media Air Cleaners, and Electronic air cleaners. The Honeywell Electronic Air Filter destroys almost 98% of pollutants and comes with a 5 year-warranty.
There are many different kinds of air filters available today, such as HEPA, standard, pleated, electrostatic and electronic filters. They should be changed once a month. Pleated Air Filters catch around 35% to 40% of the particles in the air. 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 and air purifiers can help in this regard. Things like foam, ruffled paper, fiber glasses are used as air filters.
In the market these days, you will come across different types of air filters such as HEPA, standard, pleated, electrostatic and electronic filters. 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.
