How to Choose the Right Air Filters

This is a series of ac maintenance tips. The air filter in your home air conditioning system is extremely important, but it is often neglected. To ensure proper filtration, you need to think about 3 things: the correct filter size, and your individual needs. For example, do you have pets? or allergies? Do you prefer disposables or a permanent filter? There are many types of air filters available, but once you’ve decided on what suits your family best, it’s really simple.

First

The first step is to make sure you know the correct filter size for your system. Using a filter that is too small or too large will not filter properly. The air pressure inside the system presses the air filter against the frame of the filter slot which acts as a seal so that air does not leak around the edges. All you have to do is make sure the filter size fits into the slot and is large enough to touch all four sides of the frame. You can usually find the nominal size of the filter printed on the filter itself. It is important to remember that the nominal filter size is not the same as the actual filter size. The nominal dimensions are usually slightly larger than the actual filter dimensions.

Finally

Finally, when choosing the right air filter for your home, you need to decide whether you prefer a disposable filter, a washable/reusable filter, or an electronic air filter. Disposable air filters are generally inexpensive and should be replaced every three to three months, depending on the filter and the home environment. Washable filters are slightly more expensive upfront but can be reused for several years before replacing them. These filters are designed to be cleaned/washed every month to three months. Electronic air filters are permanent accessories in the heating and cooling system and require an electrical connection. They are more expensive than any other type of air filter, but they are very effective at removing particles from the air. Electronic air filters polarize air particles and collect them in a disposable pad of low static polarized media. To ensure long-term effectiveness, you should regularly clean the unit and replace the filter pads. That is a very important step for your ac service.
