BLUEAIR Bedroom Air Purifier, Air Cleaner Dust Pet Dander Smoke Mold Pollen Bacteria Virus Allergen, Odor Removal, for Home Office Kitchen, Washable Pre Filter, HEPASilent, Medium Room, Blue 311 Auto

Tengo 2 purificadores, un dyson y este, el primero tiene control remoto y una pantallita que muestra el funcionamiento tiempo real y coincide con “lo qué pasa” en el consultorio; me recomendaron mucho este otro y en su modalidad automática hace lo que quiere, estas quemando algo y el humo pasa literal frente al aparato y no se enciende 😐…

This air purifier is quiet and efficient. It runs throughout the day mostly silent, cleans our air well, and has a beautiful design. I am impressed by how quiet this air purifier is! I've had many air purifiers over the years and most of them were loud, either with fans or electrical humming. The blueair purifier runs all day completely silent. This is one of the top reasons I wanted it. The only time it becomes louder is if it detects more pollutants in the air, which kicks the fan up higher. Even at it's highest setting it's not loud. I would say it's less quiet than a box fan. I LOVE how quiet it is. I have sensitive lungs and I suffer when the air isn't clean. The pollen in the air has been brutal, so I wanted an air purifier that could work in addition to the other ones in our home. We have a little town home and I use this one in our living room. I have placed it at the corner of the living room by the dining room and kitchen. I accidentally burnt a meal while cooking and the air purifier automatically kicked up to the highest level until the air was clean. That alone is impressive. Recently, all of our windows were open and the air purifier fan kicked up to it's medium level fan, then it's high level. My kids and I were wondering if the fan had malfunctioned, none of us had done anything to cause it to react. I went to the window and realized that it was hazy and smoky outside. We immediately shut all of the windows. The air purifier stayed on until the air in our house was clean again. Then it went back into low-level, silent mode. I absolutely LOVE the auto-detect feature. It's small enough to be out of the way, but big enough to do it's job. I love the beautiful design. It's about the height of a box fan. I love that it's round and tall. We have the original prefilter that it came with but I'd like to purchase more. I'm excited to try out another color, but I also really love the grey. The only downside is the prefilter. As much as I love it, our cat loves it more. She loves to launch herself full speed across the room and do a running leap at the air filer, grab at it with her claws and fling herself around it like it's a toy just for her. She ferociously rips and pulls at it like it's a beautiful scratching post. We've tried putting new scratching pads and all around it to deter her, but she loves the blueair more. I have removed the prefilter in hopes of detering her, so that she'll leave it alone. She has lost all interest in it with the prefilter removed. I'm bummed because I love the look of it WITH the filter on. It is so hard to take the filter off and put it back on. I kind of wish it was able to simply velcro on instead of having to slide it on. It reminds me of trying on prepregnancy pants after I had my kids. So difficult to shimmy into! Despite this one problem, I love this air purifier and will definitely be purchasing another in the future for our downstairs bedroom!

due to a road diversion, my residential road has become a main road with irritating amount of traffic. My baby Was struggling with constant allergies ( running nose, blocked nose, always breathing thru mouth) and i was also constantly having phlegm, dry-red eyes etc. I got this item as it seems to be certifed from the allergy and asthma association. I can tell that it is quite effective in immediately reducing the intensity of allergies. within 2-3 days of using, my baby started breathing easily and my problems also disappeared. interestingly, my quality of sleep has also improved. not having fine particulates in our lungs are far more beneficial than we think. make sure u close your windows and doors of your room when using this. i use it with the AC in the room or the fan in the room and the whole room feels so comfortable. Ease of use - childishly simple, my kid operates it herself as there is only one button. Noise - super quiet when used in night mode. i first run it in the room at max mode for 15-20 mins, then change to night mode when going to sleep. weight - very light, u can carry to any room u want. seems to be just ~1 kg weight. So i am a happy customer. long term review will depend on life of filter and easy availability of replacement filters. wud happily recommend to anyone who struggles with dust allergies or who lives in areas prone to traffic.

I bought this product after going through the review ...but i am very disappointed with it ..it worked for 4 days max and just stopped working. Even when it was working it use to make suction like exhaust fan sound once the bedroom door use to be open. Now only red light is on rest it is dead.

I own 3 of the 411+ that are used in bedroom/office for last few years and I’ve have been very pleased with the 411+ air quality performance so when I saw a deal on the 311+ Auto for $195 I snatched it up instantly. Its a lot bigger then the 411+ but the fan sound is just as quiet if not quieter then the original 411+. It’s just the right size for the living room/kitchen. We always leave all of them running on second speed and you honestly don’t hear them at all but the air quality is much fresher and cleaner. Cooking smells are gone within an hour and lot less dust during the winter months when the furnace is running and no allergies in the summer months. Would recommend any of the blue-air filters when they go on sale from time to time or even buy an warehouse deal open box one on Amazon as most of the time it’s just a return that someone changed their mind. The only con is the original filters can get a little expensive but you can buy third party for a lot less if you choose too but I did notice a difference in the air quality from the original filters vs third party so just a heads up if choosing third party filters for any blue-air air filters.
