All filters are not created equal!
Beware of the filters you use. When you go to the hardware store to pick up new filters, you may see some filters which are self-described as “miracle filters”. They claim that they will catch a huge amount of the dirt that ordinary filters cannot stop. These filters are ultra dense and can result in a restriction of the air flow and can cause exactly the same problem that a dirty filter will. In our opinion, just stick with a regular filter.
The key is – change those throwaway filters regularly and if you have an electronic air cleaner, which will pick up most of the dirt in the air, wash it regularly. Do this and you’ll have a more comfortable home and a lower utility bill!
