I now have 4 of these air purifiers running in my 2 story house. They went to working right away and I am amazed at how quickly they detect things in the air that I can't even see. The best part of my experience with them is my sneezing stopped within a day after I started running them.
This is very nice so far. Hopefully it lasts more than a few months unlike my Shark. This cleans the air quick! I have had it for a week or so now and my nose is not stuffy anymore! Also, all other air purifiers must make a very high pitch noise that scares my dogs- as soon as I replaced my Shark with Blue- my dogs stopped shaking and pacing around! LOVE IT- so far.
Blue Pure 311+ Max Cleaner Review. Works well. Others had reported it was noisy but I don't have an issue. There is a slight noise on #2 but it isn't that loud to me. I find it easy to ignore sound.
I was disappointed in the silver base as it is too large for this model. It probably is meant for a larger model. I found out later you didn't need the silver base but I had already bought it. At first I worried the cat would knock cleaner over as it isn't fastened to base. It is just loosely sitting on base. Cat initially checked cleaner out but now ignores it.
Thank you for sharing your detailed feedback on the Blue Pure 311i Max. We’re glad to hear it’s performing well and that the sound level has been comfortable for you. We appreciate you noting the chrome ring base experience. It is designed for our larger Blue Signature models, which explains the fit. Thanks for choosing us and for welcoming cleaner air into your home.
I purchased the Blue Pure 311i+ Max for my ~600 sq ft finished basement to add some flow to what felt like stagnant air and to help with a persistent odor that I couldn't identify. Not only has the unit solved both issues, but it's super quiet and the air feels fresh and pure 100% of the time. I'm so happy with this device.
Even though we have an overhead vent above our stove I often stink up the house when I'm cooking. The Blue Pure unit does a good job removing the smell. It's easy to tell with the color coded air quality indicator. The app is nice for keeping track of the filter 'health'. We still have quite a while before a new filter will be needed. I was concerned about having to replace it too often but that doesn't look like an issue.
Thank you for the great feedback on your Blue Pure 511i Max. We’re glad to hear it’s helping tackle cooking odors and making a noticeable difference in your home. It’s great that the air quality indicator and app are making it easy to track performance and filter life. We appreciate you choosing Blueair and hope it continues to support a fresher, more comfortable space.
