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.
