Is it time for you to change your HVAC filters? Through December 13th, head over to Filter King where you can score FREE shipping, plus up to 20% off on air filters in any size with our exclusive promo codes!

  • HIP2SAVE20 – 20% off 12-packs or higher
  • HIP2SAVE15 – 15% off 6-11 packs

Filter King carries standard and nonstandard sizes – even custom-made filters you won’t find at the hardware store! Plus, they offer many filtration options, including MERV 8, 11, and 13 filters, as well as odor-reducing options, depending on your household needs and HVAC system requirements.

Hip Sidekick Sara was especially excited to find carbon filter options, as they filter VOCs, and Sara has recently done some painting at home.

We love that shipping is free and Filter King filters are made in the USA. You can schedule recurring deliveries every 1, 2, 3, 6, or 12 months, AND you’ll save an additional 5% with auto-delivery! (Set it and forget it, and never have to run to the store again for last-minute filter changes!)

Plus, if you’re not happy with your filters, you can send them back within 30 days for a full refund.

HIP TIP: It is recommended that you change your air filters every 60 – 90 days, depending on the filter type, thickness, climate, and whether you have pets and allergies. Check out this helpful guide if you’re not sure.

Check out the Hip team’s thoughts on ordering from Filter King…

I recently ordered an 8-pack of 16x20x1 furnace filters from Filter King, and I was really happy with how easy the whole process was! Their website made it simple to find the exact size I needed, compare the different options, and place my order. Shipping was quick, too, and everything arrived nicely packaged. I love having extra filters on hand, so I’m not scrambling to buy one when it’s time to change it out!

One thing I thought was worth mentioning is their customer service! I was browsing reviews on Trustpilot and noticed SO many 5-star reviews from people sharing how helpful Filter King was when they accidentally ordered the wrong size or had shipping issues. I didn’t personally need to contact customer service, but it’s always reassuring to see feedback like that! – Bryn, Hip Sidekick


These filters arrived super fast, fit perfectly in our awkward-sized furnace, and I love that they’re made in the USA! I chose the Carbon filters for our home since they filter VOCs, and we’ve recently done some painting in our home and also bought some new furniture. Thankfully, my husband is always on top of changing our filters, but it’s good peace of mind to know they will remind you when it’s time to change them! We’ll never be making special trips to the big box stores to grab filters again now that I know how simple Filter King makes it…it was effortless. – Sara, Hip Sidekick

  2. Kandia

    • Amber (Hip Sidekick)

      You’re so welcome! So sorry, Kandia! Thanks for letting us know the size you need! I’ve passed this along to the team for if we see that one included soon! 🤞❤️

      • Martin

        Just an FYI… those codes work for any and all sizes available on Filter King website

        • Amber (Hip Sidekick)

          Thanks, Martin! We’re checking on this!

    • Amber (Hip Sidekick)

      Hello again! The code has been extended and should work on all options if you wanted to try once more on the one you need! Let us know if you have any issues!

    Over inflated prices so that the up to 80% discount brings it down for normal price you can find these for online elsewhere!

    • Amber (Hip Sidekick)

      Thanks for sharing your feedback! ❤️ We actually did quite a bit of price comparison before posting this deal, and the prices after applying the discount code are very competitive and best of web compared to other similar online filter delivery companies! And it’s especially helpful to a lot of people unable to find filters for non-standard sizes! We know every deal won’t be the best fit for everyone, but we wanted to share this one for those looking for a good price and more flexibility in finding the right filter for their home! As always, our readers are our #1 priority and we really appreciate your feedback here. 🥰

    Being able to get nonstandard sizes shipped is huge. Our odd-size filter is never in stock at the hardware store. Buying a 12-pack with 20% off and free shipping probably beats the per-filter price at most big-box stores. Good reminder to check ours before winter!

    • Amber (Hip Sidekick)

      YES! Thanks for the feedback on this sale! Such a great offer for all sizes!
