Analogous to change in technology and the ever-increasing pollutants in the atmosphere, home air filtering technology has undergone a massive change. Today, many home air filters are layered with chemicals for killing the mold and dust spores, and sanitizing the filter to dispel impurities.

If you live in a heavily populated vicinity, there is a high possibility of dust particles collecting in your air conditioner. These filthy dust particles may probably hold up the condenser of the air conditioner and compel it to work intensely. As this would hamper the longevity of the air conditioner and affect its performance in the long run, make sure you steam-clean the air conditioner at least once in two years. Besides, if you live in a highly polluted area, a yearly clean up would do you good.

Furnace filters and air conditioning filters not only screen out debris and unwanted pollens from the heating and air conditioning (HVAC) systems, but they also increase its productivity. If you replace them often, your air would stay healthy and clean without any allergens and all other types of bacteria that could be harmful to the lungs. Moreover, fresh replacements help in keeping the HVAC system running efficiently by prolonging its lifespan and reducing the utility bills after regular maintenance. Make sure you check your furnace filters and air conditioning filters, the need for replacement or cleaning every month and particularly during cooling or heating season when the system is continuously used. If these filters were not changed on a routine basis, your system would have to work extra hard, increase expenses and reduce performance.

How to Clean or Replace Your Furnace Filter or Air Conditioning Filter

Following are some common steps followed for changing the furnace filter or air conditioning filter:

? Turn off the HVAC system and look for the service panel. You could either use a screwdriver or your hand for removing these panels

? Locate the home air filter close to the intake-outtake blower; it might be behind a panel or door that swings or lifts open. Remove the filter.

? Before you install the new filter, look for an arrow (arrow indicating the direction of airflow) along the edge of the new filter. Install the filter, ensuring the arrow is pointing toward the blower motor and other related machinery. Make sure you don?t install the filter in a backwards airflow manner as this decreases the efficiency of the home air filter.

? Turn your system on and check whether it is functioning properly.

Conforming to the above given steps you would easily be able to change the home air filter. If you are unable to change the air filter, call for a heating contractor and watch how they change the filter.

Furnace filters and air-conditioning filters are available in permanent (with metal framing or fiberglass) or disposable (with cardboard frames). Disposable models are very cheap, but need to be replaced within a time span of a month. Therefore, it is better if you have spare filters on hand to save time during the course of the year. On the other hand, permanent brands are cost-effective. All furnace filters and air-conditioning filters come with a MERV (Minimum Efficiency Report Value) Rating that denotes the capability of the product in comparison with the other various brands. The higher the MERV rating, the more beneficial your filtration will be. Learn more about furnace filters at http://www.webproducts.com/Categories.bok?category=Furnace+Filters.
