Blue Pure to the rescue!
I love the Blue Pure 411i Max! It is VERY quiet and efficient. One day I sprayed a cleaning product in the shower and let it set. 5 minutes later I entered the bedroom outside of the shower and I noticed a red light on the air purifier. Although I didn't smell the residual cleaning product, the Blue Pure app showed that the air in the bedroom was actually polluted! Of course my Blue Pure 411i Max cleaned the air completely in a short amount of time. I was impressed!

Disappointing
My husband and I bought this about a year ago and after a couple months the lights and indicators stopped working. It is very disappointing as we are affected by the forest fire smoke right now and were counting on this machine working.

Another tool to help those with breathing problems
We use this in the room where my husband sleeps. He has COPD and has difficulty breathing. He is on oxygen. The Blu Pure provides some relief keeping his air clean.

Fantastic air purifier
I love this air purifier. It works more quickly than any air purifier I’ve ever owned AND it’s quieter too - even at the highest setting!

Quiet, Sleek, Easy to use
Quiet, sleek, easy to use. Perfect for our bedrooms. Setting schedules for it to turn off and on are amazing.

Overly Complex! Frustrating Set Up!
New out of the box. RTFM (Read The Frakin' Manual) Page 3 indicates DO NOT USE AN EXTENSION CORD OR POWER BAR. The "plug" is not a regular plug but some hi tech power converter/sensor. Somehow that dongle knows when an extension cord is used. That really limits room placement options and set up. That's a real show stopper in my books! Why design this unit with that limitation. Plain dumb IMO. Buyer be ware.

Thank you for your review of the Blue Pure 411i Max. While we don’t recommend using an extension cord or power strip for safety reasons, the unit isn’t designed to detect or disable functionality based on how it’s plugged in. What you’ve described doesn’t sound like typical behavior, and we’d like to learn more. We’ve reached out to you directly to better understand your experience and help resolve the issue.

Great air purifier!
Love our air purifier! This is actually the third one in this series that we bought. We first bought a larger one for the main floor of our townhouse. Then we bought a small one for our master bedroom. Then we bought this medium sized one for our vacation condo. The style is simple, and the app and set up is a breeze. Great product!

Very happy with this purchase!
Very good air cleaner, especially for the price. I can sleep with it on low. When I turn it up higher, the sound is similar to the white noise machine my daughter uses.

Weird noise
Always do your research before buying. I was attracted by the modern design of the product so I went ahead and bought it. 1 year and now this purifier makes such a weird rattle noise. Doesn’t matter the fan level, the noise is always there. Such a waste of money

Super quiet room size filter
This is a very quiet and flexible filter. It is a good size for a bedroom and if compeltely quiet when in night mode. It can be programmed to stay in night mode when you are in bed and auto mode when you are not. The filters are a bit expensive but only have to be changed every 6 months.

It works great!
I’ve had one in our bedroom for years that works great. I wanted to get one for our main living room. We had a lighter that caught fire inside our house that created a little bit of smoke and ash and this purifier immediately turned on and helped clear the air. Completely convinced it helps.

Great Product
This air purifier is a wonderful size for a small bedroom or small room. It is quiet and delievers excellent results immediately. Along with frequent dusting and vacuuming the room I have this in makes it much easier to breathe in.

Detects polluted air so easily
Cleans air in tiny litterbox room so fast. Love that it let's us know if the air quality is getting worse. I love to leave it on in my living room where the dogs are in car there's a fire, it'll tell me the air quality is bad. I move it from room to room so it initially struggles to process air quality the first few minutes whenever I plug it back in. If it stays plugged in, it detects air quality faster.

Whisper Quiet
I researched many air purifiers for our bedroom and chose the 411i max because of it was the quietest in a nighttime mode. My wife is a very light sleeper and this one does not wake her. We are very pleased
