The air filter is an important part of your air conditioning system that should be changed once every 1-3 months. While one benefit of an air filter is to block allergens and pollutants that affect your health, the actual purpose of the air filter is to protect your air conditioner from damage of incoming debris. A clogged air filter blocks the amount of airflow that is able to move freely into your air conditioning system, reducing its efficiency. Protect your health and your home – don’t forget to replace your AC filter!
