Furnace filter cleaning tips
Which way is airflow for the filter?
Always pay attention to the arrow on your filter; it should always face the unit and away from the return air duct that carries the air that will be heated or cooled. HVAC systems push the cool or warm air out and pull spent air in, recirculating the air throughout your home.
How do I know which way the airflow is on my furnace?
Try to find the arrow that indicates the proper airflow direction. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.
Are Filtrete filters worth the money?
The short answer to this question is Yes, in general, the more expensive air filters are more productive, but a single person with no pets and allergies might not need as much filtration as a family of five with three pets and a child with asthma. Also, consider how long your air filter will last.
How often should you change the filter on your furnace?
Here are averages that may help you know how frequently you should get a new air filter at your residence: Vacation house or single occupant and no pets or allergies: every 6–12 months. A typical suburban home without pets: every 90 days. One dog or cat: every 60 days
