Works fine, fast shipping, very good contact.
Brand new and genuine sensor for Air Purifier 3. Plug and play, so it’s not big of a deal to change it. I had to replace mine because it started to be very noisy and produced buzzing sound. Everything is calm and quiet now. Seller is very responsive!
P.S. The sensor on the left is the new one and on the right is the old one. No difference, just production date is much newer.
