What Kind of Air Filter Should I Use?

Al from A&A Cooling & Heating in Apache Junction, Arizona recommends using an inexpensive air filter and checking and replacing the filter for proper air flow. Other types of air filters such as washable filters, allergen sensitive filters, etc actually “restrict” air flow due to dirt build up and can be damaging to your unit. Utilizing an inexpensive air filter but checking it every 2 weeks and changing it monthly is the key to lifespan and efficiency of your A/C unit.
