What are the different types of A/C filters?

Air filters are essential to keeping a clean and healthy indoor environment and they make your system last longer too! It’s recommended to change them every few months to ensure that dirt and dust won’t build up and compromise function. It can be overwhelming with the amount of options there are when shopping for HVAC filters. There are different sizes, types and efficiency ratings that should also be taken into consideration before buying an air filter.

This air filter will capture 99.97% of airborne particles and have a MERV rating ranging from 17 and 20 .This air filter is ideal for businesses.

This kind of filter is usually a little more expensive upfront, but if you stay on top of properly cleaning it, it can last you longer than most filters.
