Home Air Conditioning Filters


 Currently, there are many types of home air conditioning filters available in the market. Everything from 1 inch pleated air conditioner filters to special purpose filters can be found on the market.


 Generally speaking, you should replace your home air conditioning filter once 2 to 3 months but this will depend on the usage of your air conditioner.


 If you go looking for home air conditioning filters before, no doubt you may have come across the term MERV rating.


What Is MERV?


MERV stands for Minimum Efficiency Reporting Values. It is an industry standard used to measure the efficiency of air conditioning filters in filtering out particles between 0.3 and 10 microns.


Although it may seem complicated, in laymen terms, the higher the MERV rating, the better the home air conditioning filter in filtering out particular particles and of course, it is usually more expensive.


Types Of Home Air Conditioning Filters



Generally speaking, all home air conditioning filters sold on the market falls into these 4 categories based on their MERV rating. They are MERV 7, MERV 8, MERV 11 and special purpose air filters.


MERV 7 air conditioning filters provide standard efficiency and can trap larger particles such as pet dander and large dust particles.


MERV 8 air conditioning filters provide better efficiency for HVAC systems and are extremely useful for pet owners and people who suffer from allergies such as dust and pollen.


MERV 11 is the best home air conditioning filter available on the market and it is the most efficient in trapping small dust particles. If you or your family members are suffering from any respiratory illness or if your home has poor indoor air quality, I highly recommend you get MERV 11 air conditioning filters.


Special purpose air conditioning filters are usually used to get rid of odor or to get rid of micro bacteria etc.
