- DWDeana W.Verified Buyer2 days agoReviewingBlue Signature™ Small Nordic FogRated 5 out of 5 starsSmall but mighty!
I couldn’t be more happy with my Blue air purifiers. Noticeable improvement in my overall quality of life, breathing is not longer a struggle.
Most importantly my migraines have lessened.
Being able to utilize my Hsa/Fsa funds made this possible. Happy customer!
- ABAndrew B.Verified Buyer1 week agoReviewingBlue Signature™ Large MidnightRated 5 out of 5 starsNoticeably reduces dust in the bedroom and quiet
After a few weeks use, we learned that Aerosol deodorant pollutes the air quite dramatically. The filter did a great job in Auto mode - speeding up the fan until the air quality had returned to normal.
It is very quiet.
