How to claim air purifier deals on Koupon.ai:

Some of these deals need a code and some are straight price drops. Our guide on how to use a promo code covers the details; here is the short version.

1. Open the deal on Koupon.ai.
2. For a code deal, tap Copy code. The code is copied to your clipboard and Koupon opens the product on Amazon. For a price drop, tap Get deal on Amazon instead.
3. Check the size, color or bundle on Amazon—the deal is tied to that exact option.
4. At checkout, paste the code into the promo code box and the discount comes off before you pay. Price drops are already applied.

🔹 Pro Tip: match the purifier to the room size, and if you're between two, go bigger. Running a larger unit on low is quieter than running a small one on high.
