Key takeaways

  • Oply users get 15% off Filter King HVAC filters, inside the app.
  • The offer shows up next to the filter reminder you already rely on.
  • A clean filter can cut air conditioner energy use 5% to 15%, according to the U.S. Department of Energy.

The deal

Oply users get 15% off Filter King HVAC air filters. Open your filter reminder or the Savings tab, tap the offer, and check out with Filter King.

Why it matters

The Department of Energy says replacing a dirty, clogged filter with a clean one can lower an air conditioner's energy use by 5% to 15%. It is one of the cheapest jobs on any maintenance list, and one of the easiest to forget.

Oply's filter reminder defaults to every 3 months. A lower price on the filter itself makes the habit easier to keep.

Which filter do I need?

Your size is printed on the edge of the filter you have now, like 16x25x1. Save it in Hub once, along with the MERV rating, so you order the right one every time. Not sure what MERV means? Read Filter King's MERV guide.

How to grab it

  1. Download the Oply app on iOS or Android.

  2. Add your filter size in Hub. Snap a photo of the filter's edge if that's easier.

  3. Open the filter reminder or the Savings tab and tap the Filter King deal.
