For many homeowners in San Antonio, choosing an a/c filter is really not an easy task; however, it’s not an impossible one either. One thing is for certain; it is the simplest and most basic thing an a/c owner can do to help maintain his a/c unit.
Filters come in two kinds: a Flat Panel or Pleated Filter (extended surface). Flat panels come in fiberglass or polyester materials, with polyester being considered by many as superior. Pros: they are more inexpensive. Cons: they have a short lifespan.
Pleated Filters come in either polyester or all synthetic material. At first glance, they look very similar to an accordion. Pros: the pleating kind provides a more available area to accumulate debris and fewer filter replacement are needed. Cons: they are more expensive than flat panels.
Having figured out which kind to use, the next three most important things to decide are the size, cost, and MERV of the filter. First in order is to determine the filter size depending on the a/c unit which an owner has.
Each unit has a specific size and this information is readily printed on the actual filter itself. If you don’t already have a filter inside the unit, you’ll have to measure the actual filter by taking a tape measure and taking note of the length, width, and depth.
It’s wise to remember that the measurements taken by the buyer are exact, while the manufacturer may have “nominal” measurements. When purchasing, it is necessary sometimes to tell a clerk the figures are exact and not nominal.
The cost as said before depends on the style filter such as either a Flat Panel or a Pleated Filter, which is more expensive. Since Flats last less, it may be a good idea to buy a couple at a time.
The MERV or Minimum Efficiency Reporting Value is the industry standard for purposes of filter comparison. Generally, anything above a 12 is considered as being not appropriate for home users, with a 1-12 being determined to be the best for residential use.
