No matter which size BTU a commercial or central home heating systems happens to be, furnace filters are required to be replaced. Replacing furnace filters is crucial to efficient operation. The cleaner the air circulated through the furnace, the less mechanical problems or, in the worst-case scenario, furnace failure, will occur. The cost of furnace filters being relatively inexpensive, it’s prudent to purchase enough furnace filters for a full winter season.

How Often Should Furnace Filters Be Replaced?
Professional heating and cooling experts recommend replacing furnace filters every 6 weeks, depending on age and furnace use and type of furnace filters recommended by the furnace manufacturer. Check the furnace operations and maintenance manual, or “Users Manual”, supplied by the manufacturer and provided by the installer. These manuals serve as a reference point for the correct type of furnace filter and for the types of parts that may need replacement.

One of the most important things to keep in mind is the specific size of the furnace filter. During time of purchase, it will be necessary to choose the correct size. Look for a number that is indicated by width, length and thickness. As an example, one of the most common furnace filter sizes is 16 x 25 x 1, although there may be others that are smaller or larger than this.

Types of Furnace Filters
The materials from which furnace filters are made are also fairly common:
1. Fiberglass
2. Electro-static synthetic fibers
3. Polypropylene

The types of furnace filters available range from the least expensive fiberglass filters to the most expensive which are a combination of an electrical air filtration and an air cleaner system.

Furnace Filters for Specific Needs
If allergies are a serious problem, furnace filters with the designation “HEPA”, are most effective in reducing dust and pollen in indoor air. There are other types of furnace filters that are designed with a 90% arrestance of irritating substances in air flow. Take note of the sizes of micron particles a furnace filter is designed to capture.

Installing a Furnace Filter
Installing a furnace filter is relatively simple. Do not attempt to replace or install a furnace filter without first turning the furnace blower to the “OFF” position. Check your Users Manual to locate the blower section of your furnace. In most cases, a slot is located between the blower and filter housing. Simply, slide the furnace filter in with the air flow arrow pointed in the designated direction on the furnace filter and replacement is complete.
