Why should I change my air filter every three months?

  • Lower energy usage by up to 15%: According to the Department of Energy, a dirty, clogged filter can obstruct airflow and cause a decline in the performance of your HVAC unit.
  • Improve air quality in your home: Filters keep pollutants like mold spores, pet dander, smoke and pollen from circulating around your home.

How do I know when to change out my filters?

When you place your order with us, we will automatically send you email reminders throughout the year, notifying you when it’s time to switch them out. If your inbox is already flooded, you can change how often you receive them or unsubscribe from those reminders completely.

What is a MERV rating?

MERV stands for “Minimum Efficiency Reporting Value” or the effectiveness of the air filter. The higher the MERV rating, the more efficient the filter is at keeping out dust particles and other contaminants.

How do I know what size I need?

Most filters have the size printed on the frame. If your current filter is a good fit, order the same size. If there’s not a filter in your system, turn it off and measure the opening. If you have questions, call 1-888-44-SMART and one of our specialists will help you.

Where do I find my filter?

Look in one of two places – around the blower or behind a return grate (which could be on a wall or ceiling). When installing your new filter, make sure to follow the directional arrows on the frame.

What if the filter in my system lists two sizes?

You may notice two sizes printed on your filter. The “nominal” size is the rounded number used by most manufacturers. The “actual” size is the true measurement of the filter. Use the “nominal” size measurement when ordering.
