Change That Furnace Filter
Regularly changing a furnace filter to keep indoor air clean, fresh, and pure is critical, not to mention it helps to lower your heating costs. Indoor pollutants like dust, pet dander, and allergy-causing pollen can cause havoc with your respiratory system as well as your heat bill. And really, changing out a furnace filter just isn't all that difficult.
A furnace filter, sometimes called a home air filter keeps coils and heat exchangers on your heating system running smoothing by helping them to stay clean. Your system may continue to work, but without changing the furnace filter occasionally, it will work harder and much less efficiently. Changing the furnace filter religiously also prolongs the life of your heating unit.
As mentioned before, a furnace filter also keeps the air breathed by you and your family cleaner. Of course, how dirty your home air gets depends on how many people live in your home, whether or not you have pets that shed, if you smoke, and other things.
Persons suffering from allergies or who have asthma should be conscientious about changing a furnace filter often - even checking it out every couple of weeks or so to check how dirty it's getting.
Even an expensive, high-quality furnace filter can't help clean the air in your home if you do not change it regularly enough. Every month should be a minimum for changing a furnace filter; more often if allergies or asthma act up, you're doing any sort of a remodel job, or if the house is brand new with dust still settling from its construction. Of course, if a dust storm occurs in your area, afterward would be a good time to change a furnace filter, as well.
Even a high-priced furnace filter doesn't cost as much as your health is worth. So a good rule of thumb is to be safe, rather than sorry. The bottom line? Change that furnace filter - often and regularly.
