June 30th, 2017 by Darwilladmin
True enough, there are lots of air filters available in the market. However, it takes a good air filter to provide your home with excellent air quality. On top of that, changing your air filters more often will not only maintain your indoor air quality but it will also keep your air conditioner’s function efficient during its lifespan. But what type of air filter is the best?
The Different Types of Air Filters
So far there are five most common air filters for your air conditioners. Each varies according to their physical design and energy efficiency. The different types of air filters are the flat-panelled fiberglass air filters, the pleated media air filters, high-efficiency air filters, the true HEPA (High-Efficiency Particulate Air) filters, and the washable air filters.
Washable Air Filters
Washable air filters can be made from plastic or metal. They have layers of polypropylene weave or wire mesh material that prevents certain pollutants from entering your household. However, they have a few disadvantages like having a low MERV rating of 1 to 4, an attraction to mold development and are more expensive than the disposable filters.
Flat-Panelled Fibreglass Air Filters
The fiberglass air filter usually carries a MERV rating of 1 to 4. The disposable filter of this model is made up of layered fiberglass fibers. It is inexpensive and is not made for cleaning the air since they only remove 10% of air pollutants in your household. These filters are very thin and are purposely manufactured to provide protection for heating and cooling components instead.
The Pleated Media Air Filters
With a MERV rating of 10 to 13, the pleated media air filters are obviously better than the fiberglass filters. They can remove up to 45% of the air pollutants in your home. However, its structure has similar compositions with the fiberglass filters. It also has disposable pleated polyester filters. However, pleated media filters are often mistaken for HEPA filters because they are large and have a few similarities with HEPA filters, but a lesser airflow resistance.
High-Efficiency Air Filters
These filters are commonly known as the practical filters for most residential HVAC systems. High-Efficiency Air filters have a MERV rating of 14 and 16 and can remove up to 85% of indoor pollutants. They are capable of trapping very fine particles in the air such as pollen, dust, mold and other micro irritants. Some of these filters are even coated with chemicals that kill microbes.
True High Efficiency Particulate Air (HEPA) Filters
True HEPA filters have the best filtration structure for your home and it is highly recognized by the Occupational Safety and Health Administration. These filters can remove up to 98% of air pollutants indoors and can block elements that are 0.3 microns. HEPA filters have 17 to 20 MERV ratings. However, because of its large size and ability to restrict airflow, most residential HVAC units can’t accommodate them. They can be used as a solo air purifier or an entire house filtration system instead.
