I know how great it is working when I replace my filter. I like that the light tells you when to replace it and since I have birds and dogs, it really helps with allergies!
I bought 2 PuroAir purifiers. I notice I don't wake up sneezing like I used to. Good quality. Seems to get the job done & the filters show the dirty work!
We had air sensor problems that started last year, but were addressed with a factory calibration reset. The problem started again in June, but the reset procedure didn't seem to work this time. Otto P. was very helpful with suggestions and understanding our problem. He finalized solution to our issue under warranty coverage. I would recommend PuroAir company and products because of quality, service, and remedy of issues.
Bought a PuroAir 240 and did the flour test and nothing happened. Light never changed color. Notified PuroAir they had me do a reset and still never changed color. They replaced it at no charge. Got the new one and have the same issue. It doesn’t matter what we are cooking or what odors are in the house the light never changes from green. Not impressed and would not by another.
