People are looking for ways to improve the quality of the air in their home and we've been getting lots of questions regarding pleated air filters. All filters impact your system's "static pressure", which is a measure of resistance to air flow. If the resistance is too high, your system is essentially choking. Amongst other things, this can make your heat exchanger fail and cause your coil to freeze.

As any filter fills up, it increases the resistance to air flow throughout your system. Pleated filters have the potential to hold more dust and allergens and are structurally stronger than regular filters, which poses a greater threat to air flow.

The important thing is to check your filters every 30 days, regardless of how long they are supposed to be good for. If they are dirty, either clean or replace them.
