How It Works

We make it easy to install the right type of filter each season. You’ll receive a unique sequence five Seasonal Air Filters™. Each will be dated and color-coded telling you exactly when to replace the air filters. We’ll also send you an email notice to remind you that it’s time.


  • Select your state

    We build you a cost-optimized SeasonSmart Plan based on your zip code.

  • Select the number of air filters

    Select how many filter locations are in your home. Often filters will be of different sizes.

  • Select filter sizes

    Choose your filter size. The proper size should be listed on the side of your current filters. That’s it. We’ll take care of the rest.

Did you know?… the Department of Energy says you can save up to 15% on your energy bill just by changing air filters at least every 90 days! That’s why we offer a FREE email reminder service. And because every 90 days isn’t optimal for everyone, we can customize your schedule based on where you live and on your local air quality to maximize your savings. So sign up, receive an email reminder, and start saving today.
