7400 Smart Filter Replacement Compatible with blueair protect smartfilter 7400 Models 7410i 7440i 7470i Air Puri-fier, 4-Stage with H13 True HEPA Filter, Activated Carbon and Dual Pre-filter, 1-Pack

Fits well and so far works fine.

Excellent generic filter for my air purifier. This is a perfect substitute for a filter that is around $75 name brand.

THESE PURIFIER FILTERS ARE SO EASY TO INSTALL IN MY BLUE AIR PURIFIER AND THEY DEFINITELY KEEP THE AIR CLEANER THAN I THOUGHT THEY WOULD. GREAT FOR COOKING ODORS AND FOR CLEANING THE AIR OF DUST AND ALLERGENS. I RECOMMEND THEM

The red light on my filter stayed on from day one. Despite cleaning machine head to toe. Day two I opened up and saw white powder all inside the machine clean it again. Red light still on. This is a piece of garbage. Don’t waste a good expensive Machine by inserting a cheap product.

I was worried about the machine rejecting this replacement as many devices do if you don't buy their exclusive parts. Not the case, so, all that remains is to see if it does the job and for how long. I know the original worked because the A/C filter lasted for 3 months like new.

great thanks

fits well in the air purifier.

Perfect Match
