How To Choose An Air Cleaner For Your House

Undeniably our atmosphere, our environment, the air that we breath is full of particulates and pollutants that most often pose a danger to our health and well-being. These airborne pollutants such as dust, tiny carbon particles, pollens, allergens, and other irritants may come from several sources: smoke-emitting factories, vehicle exhaust, plants and pets and even from the daily bombardment of cosmic particles. These pollutants then find their way into our homes and if left unchecked may be inhaled by members of our household and lodged into their lungs to cause a number of diseases of the respiratory tract. We cannot take this for granted and compromise the health of our loved ones. You can read more on this at

For this reason it is incumbent upon us to install a good air filtration system to stop or at least minimize these pollutants and irritants from causing harm to us

Here’s how to chose the best air cleaner or air filter for your house:

The quality of any air cleaner or filter whether the cheap ones or the more expensive kind is as good as the proper care and maintenance given to it. The cheaper kind should be changed or cleaned once every 2 or 3 months; the expensive ones may be good for at least every 6 to 12 months. This maintenance should be on a regular basis not at random or as the need arises.

The most common types of air cleaner or filter use in the residential HVAC system are the mechanical air filters. These are made of synthetic fibers fine enough to trap dust, debris and small pollutants in the air. The efficiency of these mechanical filters is measured in Minimum Efficiency Reporting Value of MERV. So the cheaper ones have lower MERV value and therefore less efficient and must be changed more frequently.

Mechanical air cleaner or filter comes in several types:

Fiberglass air filter are very thin and cheap and can remove only ten percent of air pollutants. Their MERV rating is only between 1 and 4.
Pleated air filter with a MERV rating of 10 and 13 is a little expensive and can remove up to forty five percent of the air pollutants in the home. Its efficiency is directly proportional to the number of pleats per foot.
High efficiency air filter is the most practical to use in residential HVAC system with an efficiency rating of eighty five percent and a MERV value of 14 and 16.
High Efficiency Particulate Air (HEPA) filter is the best choice for your house because it can remove ninety eight percent of air pollutants and with a high MERV rating of 17 and 20.

In conclusion, air cleaners or air filter cannot totally eliminate the particulates in the air but can at least minimize them to a safer level. These particulates vary in sizes from the smallest (.001 microns) to the largest (one hundred microns. The fiberglass filters are better at trapping large particulates but not the smaller ones, whereas the high efficiency filter is good for small particulates than the larger ones.
