Scheduling should work better
on February 16, 2026
Posted by: Shelly A.

I need to schedule the Signature to operate during a specified time period at a specified fan speed. I have to take it off its default ‘Auto’ mode to get it to turn off at a specific ‘off’ time. When it comes back on at the specified ‘on’ time, it comes on in ‘Auto’ mode at a lower fan speed. I have to then manually set the fan speed I want. This manual act takes it out of ‘Auto’ mode, which then enables it to turn ‘off’ at the scheduled time. My 211i Max model’s controls operate so much better.

Perfect

Small but powerful unit. It just works, really nothing else to say. All my air purifiers are Blue Aire. I have not tried anyone else and just being don't see a need to try anyone else. No gimmicks, no smoke filled chambers, these work. I owned 10 of them. Enough said.
I would recommend this to a friend!

Totally enjoying the Blue Air. Although we usually have a clean air indicator it picks up something and gets to work.

Unable to register product

When I click on the Devices & Warranty section on your website, the Devices & Warranty window is empty. Therefore, I cannot register my Signature air purifier. I opened a help ticket 662734 but your chatbot could not solve the problem.

I’ve been real happy with the results from my new air purifier. I have dogs in the house and a lot of dust. There has been a notable difference in air quality in the first week.

Great purifier

Easy to use, clearly shows where my home is at. The cool clean air feels really purifying. The equipment really does look very sleek and it’s not loud at all.
