Review: 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 😐…
Review: 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.

## Questions & Answers

**Q: How long does a filter last? I bought mine 3 weeks ago and the red light already came on signaling it needs to be replaced.**
A: Which red light?  The red light for filter replacement is on top and shouldn't come for 6 months or more depending on how long and high the fan setting. Page 11 of manual. The red led on front side is red if polluted air is detected, then yellow then blue when air is clear. Page 10.

**Q: How much do the filters cost and where do I get them**
A: As of 7/13/2022, Amazon sells replacement filters. Original is $21.

**Q: Do you have to use auto mode?  To reduce noise we may want to use low setting at certain times, is that do-able?**
A: You do not have to use these machines in Auto Mode. You can set to a manual speed if you would prefer to have controls over the fan speeds.

**Q: Consumer reports rates the 411 Auto very poorly for filtration at any speed.  Does the manufacturer have a response to this?**
A: I subscribe to consumer reports, but I am not always a fan of their review methodology. I think the problem here is that they compare all sizes of purifiers together, when the smaller units should be compared with other smaller units. Of course, a larger unit with higher CFM air flow and larger filter area will perform better than a smaller unit. Other review sites gave this purifier good ratings for its size. Some recommend just buying the larger unit, which is rated highly by Consumer Reports and running on a lower speed setting.

### ⭐⭐⭐⭐⭐ Review
*by A***. on 30 June 2021*

This is now our 2nd Blue air purifier. I originally bought the smaller Blue 411+ for our bedroom and I was very impressed with how having that in our bedroom improved my lifelong allergies that I take a daily pill for. Prior to getting the smaller 411+ I would very often wake up with a stuffed nose. Yes, we do have 2 dogs but they are not allowed in the bedroom due to my allergies. I honestly didn't have high hopes for the smaller unit but after a couple days of it purifying the bedroom air, I noticed a huge difference. I began waking up with clear sinuses and the room smelled "different". Not a bad smell but maybe just NO smell? Anyhow, after giving the little Blue a good 30 days to prove itself, I knew I needed a larger one for our living room. This is also where our dogs (golden retriever and black lab) spend most of their time with us when they are inside. And having these 2 dogs and allergies doesn't make life super easy as cleaning goes. I have to vacuum daily or every other day (minimum) and will at times pull up what looks like a small dog inside my vacuum canister. Especially, when my golden is blowing her coat. Finally after comparing, I went ahead and ordered the Blue 311 Auto for our living room which is approximately 420sf. I also bought a separate filter cover that's shown in my pictures and an additional filter to have on hand. The unit arrived well packaged and without damage. It came with a main filter installed and a a light gray filter cover but tbh, I will use the light gray cover while cleaning and drying the dark gray cover I have on it now. I as I prefer the dark (name is actually Winter Reed) over the lighter gray. I also like the quality of the upgraded cover. It's a bit thicker and looks nice. The set up was simple. It's really just plug it in and go. I like that this unit has 4 mode settings and indicator lights to show air quality and when the filter needs replaced. I have noticed one time when out of nowhere the air quality sensor light briefly turned from blue to orange then back to blue. The light sensor color indicators and level info are Blue (good), Orange (moderate), and Red (polluted). The main filter change sensor is supposed to switch on after 6 months of use but I haven't had it long enough to confirm if that works yet. For maintenance, I do run my vacuum brush over the outer filter cover once a week to clean any dust off of it which, there always is. This was also an immediate indicator to me that this fella is doing its job! I will also run a damp cloth on the the plastic exterior at the same time just to keep it clean and in the best working condition. Noise Level: This 311 Auto unit has 4 modes. ✔Auto Mode: (fan speed will change depending on the air quality it senses). ✔Night Mode: (whisper quiet, low speed) ✔Everyday Mode: (medium speed) ✔Boost Mode: (fastest speed and very loud). Boost mode is like, wind tunnel loud! Way too loud for us to watch TV in the same room if it was on. But this mode is not for everyday use. The only time I've used boost mode is when there is a specific reason i.e.,dogs came in from rain or I may have cooked/baked something that has a lingering smell, etc. I would just turn it on boost for 10 minutes or so to dissipate whatever the odor issue may be. We typically have it set on auto mode or everyday mode and it's very, very quiet. I would say auto mode is more quiet or no louder than an average fan that's on it's lowest speed and everyday mode is maybe as loud as a fan on medium setting. ▪️Please see video I took of the different modes to show the sound difference between all four settings▪️ I have now had this particular unit running 24/7 for about 2 months and we love it! We live in Washington State so when it rains and our fur babies go out for break, any "wet dog" smell is gone in minutes if I kick in the boost mode but everyday mode will also take care of that within an hour or so. Sadly, I also know fire season will soon be upon us for summer and I have no doubt both units will do a fantastic job at keeping the quality of air inside our home filtered, clean and smelling fresh during the seasonal bad air quality. We will be tackling a full home remodel next year which we'll be adding central heating and air but even then, I plan on keeping both these units up and running! Would I recommend this Blueair 311 Auto? Absolutely 100%. Summary: All in all, if you suffer from allergies/asthma like me, have animals, or simply a home without filtered air and are teetering on whether or not to purchase, go for it! You won't regret it! Personally, these air purifiers have honestly changed my life! I wish I would've found this company sooner! I HIGHLY recommend! If I must find something negative, I guess I would have to say their OEM filter replacements are pricey but this was not a deterrent for me. They also offer an auto ship filter service for a discount. I give this an easy 5 star! (I was NOT paid for this review and was not asked to leave one. I have no affiliation with this company other than being a new-ish forever customer)! Hopefully this will help someone!
