How To Choose Your Air Conditioning Filters
Changing the air conditioning filters on your unit is very important for your health and the longevity of your unit: Clogged filters can greatly reduce the effectiveness of your AC and make it work harder and more expensively, both in energy and in operation costs. A high percentage of AC filter units are full of dirt, grime, hair and other particles that block the air flow. In addition, some filters require replacement after a certain number of years; these filters may have gone bad or are faulty and need to be replaced.
It is not difficult to find air conditioning filters at your local grocery store or hardware store. While most of them are inexpensive and easy to install, there are some things you should look for in an air conditioner filter, or AC filter, when shopping for a new one for your unit:
Air purification is important because it reduces the amount of dust particles entering your unit. You can get this done easily with an air filter. This makes it necessary to make sure the filters you choose are HEPA-filtered. HEPA filters remove 99% of the tiny airborne particles and chemicals that are usually found in your home. This includes pollen, dust mites, mold spores and many other allergens and irritants. If you find filters that do not list these as necessary, check to see if there is a filter out there that is not HEPA-filtered.
Air conditioning filters also need to be changed every few months or so, depending on the age of your unit and the amount of dust in the air inside. Older units are typically more susceptible to these problems than newer models. Older units are less likely to have filters which are designed to keep dust and other materials out of the air. This causes the air conditioning unit to become more clogged, making it work harder and costing more in energy.
An AC filter also needs to be replaced periodically to ensure the continued operation of your AC. If there are any leaks in the ductwork of the unit, the air filter can get caught in the opening and cause a blockage. If the leak is not repaired, the air inside the unit will fill up with air-borne bacteria and dust particles, which in turn can damage your AC. and shorten the life of the unit.
Replacement filters for your unit should be purchased online or at a local grocery store. The best time to purchase an AC filter is during spring or fall, when they are available in your area. They are often discounted. and you are sure to find one that will fit your unit. You can learn more about this topic at https://en.wikipedia.org/wiki/HEPA.
