Convenient……………………………………………………………………………………………………..air purifiers

I have 2 of these, they are wonderful at keeping smells and dust down. And its fast

This is my second Blueair product and they never fail to impress. The Blue Pure 511i Max stands just 14-1/2" tall and at only about 9" in diameter, it's very compact and takes up very little space. The cloth-like exterior blends in nicely with any decor and they even have optional filter colors available for purchase. Using the Blue Pure Max is easy as it comes ready to go right out of the box. Simply plug it in, choose one of the three speeds, and you're on your way to cleaner air. There's a night mode which sets the Blue Pure Max to the lowest speed, although it's pretty quiet on all settings. Not only can you adjust the speed, but you can adjust the brightness level of the LED lights. It also offers a child-lock feature which can be turned on/off. It has a reminder light when it's time to replace the filter but they typically last six to nine months. Although the Blue Pure Max will work just fine without the BlueAir app, installing it allows you to monitor the filter and purifier remotely. If you don't connect to WIFI, you can even turn off the WIFI light. I'm using the filter in a guest bedroom, about 12 x 13, and it seems to work great. I can definitely tell the difference as the air smells cleaner! However, the greatest thing about the Blue Pure Max is how quiet it is. At the lowest speed, you can barely hear it, but you know it's working!

Works amazing clears a room much quicker then advertised

Really easy set up. Seems to respond well to scents

Purifier works good just a little noisy. Keeps the odors down in a teenage boys room.

Turns on and off when needed. Like i dont have to do anything but look at an app

A great product! It cleans the air effectively and works exactly as advertised!

Good to have especially if you have furry friends. It’s easy to clean.

Working great so far, when cooking it kicks in when set to automatically.

Ok does the job not so large room. Nice for small space

Good quality and does the job well.Works as expected.

Not bad for the price, still figuring out this unit

Hard to do a total review it’s only been on 2 weeks. But we came back from a 4 day vacation and the house still smells a little stale.

This is my third Blueair air purifier. I own the Blue Pure 311i Max and Blue Pure 211i Max. The 511i Max met and surpassed all the expectations I had from owning the aforementioned models. I saw the diminutive size of the 511i Max and initially thought I would need to use it in a bathroom because it's so small. It's a top performer for its class. It's simple to use and it has all the same great features of the larger models. It quietly and efficiently cleans the air, reminding me that the really good products just work. Blueair makes really good products. I prefer controlling the 511i Max with the Blueair app rather than the device itself because I only run the air filter at night and turn off the button LEDs to keep the room dark. The app provides useful information like particle count and allows for customization of fan speed, LED brightness like I mentioned, and automation settings. The Auto mode seems to work well and maintains the air based on the air quality read by it's onward sensor. Voice control is also possible through Google Assistant or Alexa, enabling hands-free operation. I connected it to Alexa but I might have called on any of the Blueair filters maybe four times ever. The air filter's performance is excellent. It's incredibly quiet on the lowest setting and quickly adapts to changes in air quality in auto mode. It really came up big when my entire family caught the flu and couldn't isolate from the kids. It's also been great when we've cooked or baked smokey foods. The 511i Max almost immediately jumped up a few speeds to clear the air fasters. I really love that the pre-filter, the outer fabric, is machine washable in a delicate setting. The filters are expensive but they last a very long time in normal conditions. No smokers or pets in our home. I highly recommend this air purifier.

Worked great until it didn’t. WiFi stopped working less than 2 months after I got it. Lucky I have Best Buy total so I was able to just return it.

Blueair 511i Max is a great air purifier for a bedroom, office or any similar size room. It's pleasing to look at and fits into any decor with it's soft gray covering. Set up is quick and easy. Touch controls on top of the purifier are convenient and light up to let you know the selection made. The Blueair app connects to the purifier quick and easy. The app gives information on indoor and outdoor air quality, filter life, as well as being able to switch fan speed, led light brightness, set up schedules if preferred, and a convenient link to buy the correct replacement filters when needed. I use my Blueair air purifier on auto mode. I like that it adjusts to what is in the air without my input. The fan will speed up when it is needed and then slow back down and gets very quiet when the air is clear. Most of the time it's very quiet and, if not for the light shining to let me know, I would think it's been turned off accidentally. The outer filter cover is removeable for cleaning, easy to hand wash or can be tossed in the washing machine.

Review for Blueair - Blue Pure 511i Max 465 sq ft HEPASilent Small Room Bedroom Air Purifier I was looking for a less obtrusive bedroom air purifier after using a much larger one during Covid. The Blueair - Blue Pure is perfect in all the ways I was hoping. First, it’s small and light, easy to move, and fits with pretty much any decor. The subtle gray fabric cover looks elegant, but is actually fully functional, too. The fabric covers the HEPA filter and acts as a pre-filter for dust and larger particles. It’s easy to take it off and shake the dust outside, vacuum the fabric, or wash the cover. Second, it’s VERY quiet. Even running on high, it’s not too distracting, but running on Auto lets it adjust the fan for the current conditions. If my wife uses hairspray, the fan cranks up to high for a few minutes and then returns to low. Finally, it allows for peaceful sleep with night mode. This turns the fan to low and turns off the main LED, while dimming the “night” LED. It’s hard to hear that it’s even running and the dim LED is not distracting. Controls are two simple buttons: one for power, and the other for selecting Auto, Night, and fan speed. When you download the Blue app, you get additional features. You can check on the filter’s functioning to see the air quality, you can set a schedule (I set up a schedule to change to Night mode at bedtime and then reset to Auto in the morning), and you can see the condition of the filter to know when it needs replacing. The unit comes with a Particle and Carbon filter to help remove odors, but you can up your game with special filters designed to remove smoke or allergens.

I've been using the Blueair Blue Pure 511i Max (long name) for about two weeks now and it has been going very well. The unit is very quiet, most times I never hear it even though it sits within 15 feet of where I sit in the living room. App: It has an app which is nice to have but I'm not sure I really need an app for an air cleaner. It does have some nice features though. It gives your room an air quality score. It also tells you the fan speed and filter life. You can control the fan speed, LED brightness, and setup a schedule. You can even add a child lock via the app if you have little ones running around. It also has some potentially handy features such as how-to links and videos. Style: The filter looks nice. The top 1/4 is white plastic and the rest is a grey mesh pre-filter. It would likely fit in with most houses. If you don't like the grey, you can order pre-filters in other colors to help match your decor. Filters: I like that the Blue Pure 511i Max filters out allergens like pet dander, dust, and pollen since a few of us in the house suffer from allergies and we have two cats and a dog in the house. It also will filter smoke - even though no one in the house smokes, this is a nice feature. Bottom line: It's a nice air filter. It is quiet and has nice features like the app.
