Know the dimensions.
Before you head to the store, make sure you look at your existing air filter and know the dimensions you will need for your AC unit. Special sizes and shapes of filters are also available for room ac cleaning, register vents and return vents in the floors, walls and ceilings. Adjustable filters are available as well for non-standard ventilation openings.
One thing you should know is that the most common type of filter used in homes, is a mechanical filter. A mechanical filter is one made up of any type of dry media filter. It can be man-made or a natural fiber. One of the first things to look at when you are shopping for a filter is the MERV rating (Minimum Efficiency Reporting Value). This rating system tells you the efficiency of the filter. Generally speaking, the lower the price of the filter, the lower the MERV rating will be.
Why is the MERV rating important?
There are millions of particles in the air and circulating through our homes daily. The most harmful ones are less than 2 microns in size. Part of what makes a filter efficient is the amount of respirable particles it can catch. This is taken into consideration as part of the MERV rating, as you can see in the chart.

Different Materials & Other types of ac filters:
Fiberglass – The least expensive filters which were not originally developed to improve your quality of air and only remove less than 10% of pollutants from your home.
Pleated filters – Remove 45% of pollutants from your home. The more pleats per foot on the filter, the cleaner your air will be.
High Efficiency Filters – The most practical for residential properties. They remove up to 85% of pollutants. These filters are sometimes coated with chemicals that can kill bacteria and mold.
HEPA – These filters provide the best filtration for your home because they remove up to 98% of pollutants from your home. Unfortunately, a typical HVAC system is not equipped to provide enough air pressure to use this type of filter. In order to use this filter, a separate HEPA filtration system would need to be installed.
There are many types of air filters out there for your home. May will have different features and benefits on their packaging. The most important thing to remember is to change your filter regularly. Even the most efficient and highest rated filter won’t be able to properly do its job if it is overloaded with dirt.
