A Sophisticated (and QUIET) Air Filter
I am reviewing the BlueAir 211i Max and 411i Max series in this review as I bought both – one for living room and one for bedroom. Bottom line, these are very impressive units and for the price I am impressed and pleased with each for functionality and effectiveness.Pros for the BlueAir series. very very quiet. On auto maintenance mode – you can’t hear the thing. These are smart machines. You can monitor every aspect of your air quality through the app. You can adjust the control lights from off to bright. It tracks months of air quality data for the room it is in by month, week, day. You can adjust from sleep mode, auto, and 3 fan speeds using the app remotely. It tells you how much filter life is left. It tells you the outside air quality and compares to your inside.Example of its effectiveness; I was sautéing some Italian sausage and onions, the unit detected the particles and immediately went into high mode for about 5 minutes until all the odor was eliminated and then went back to silent. The front LED bar changes from Blue to Green, orange and red depending on the air quality while at the same time adjusting the fan speed to address the corresponding level of air quality indicated. Same thing happened when smoking some meat on the back patio. I left the door open to bring in the food, the unit detected the smoke and the front LED went red. After closing the door, it ran on high mode until the LED indicators began to regress back to blue and the fan speed decreasing accordingly until all the smoke odor was eliminated from the room.Cons for the BlueAir product. It is a bit pricier than other options – but for all the differences – so far, I feel the Blue Air product is definitely worth the price difference, for me at least.What I have not addressed: the longivity of the products; the life of the filter; ease of maintaining; Both of my purchases are within the first month;

Great little air purifier
I like that it’s portable and very lightweight and seems to do the job. You can put it on a number of speeds and quiet to me. Great that I can move it from room to room. Would definitely recommend. I live in an apartment that has a musty smell in the bathroom and kitchen and it seems to have helped that. I leave it on all the time. Thankfully I’ll be out of here soon but while I’m still here I wanted something to keep me from getting sick.

Lo compré hace un par de semanas y me parece excelente, vivo en CDMX y el aire es de mala calidad, ahora estoy durmiendo toda la noche y se ha reducido mis alergias y el asma.

Highly rated by multiple independent review cites, good controls with variable air speeds, no sign of vibration, and at lower speeds can act as white noise source to mask background noises from interfering with sleep. Replacement filters not overly expensive compared to similar units. Unit comes with couple of different color ‘socks’ that slip over outside of unit, allowing some matching to room decor, but more importantly act as a prefilter that protects and greatly extends lifetime of more expensive main ‘hepa style’ filter. Also, take manufacturer’s filter replacement recommendations with huge grain of salt. Independent tests indicate that in many use scenarios, with prefilter sock installed, the main filter can last for several years. All hepa-style filters actually become more effective after used for a while and partially loaded with particulates; so as long as they pass good airflow they will continue to filter well. The only exception is that the charcoal coated subfilter, which most oem filters for this unit seem to have for absorbing odors and airborne chemicals etc. , lose effectiveness long before the particulate filter becomes clogged. But there’s little evidence that the thin charcoal layer in units like this actually do much even when new – effective charcoal-based gas absorbing air filters are really only found in multithousand $$ air cleaners with filters 6+ inches thick and containing several kilos/lbs of activated charcoal. Got unit as Amazon refurb, was good as new and excellent deal.

We purchased this air purifier because of wildfire smoke in B.C.We ordered this on July 30th as we expected wildfire smoke coming in the next week and this was going to arrive the soonest. However, the purifier took 2 weeks to get here due to multiple delays (on UPS’s part). But it came just in time for more smoke to roll through.The setup was really easy. Just put the “sock” (pre-filter) on the bottom of the purifier, plug it in, and bam! Clean air is on the way.Our house layout is really open and doesn’t have many doors but this air purifier seems to be doing just fine. With the claim that it can clean the air in a 540 square foot room 5 times in an hour that means that it can clean a 2700 square feet room at least 1 time an hour.The carbon filter is made out of coconut shells which gives it a nice coconut smell in the house (at first) but also tells you where the air has and hasn’t been purified in the house.Now the fan is something else. I am currently sitting in my kitchen and it is running on high 15 feet away from me and I can barely hear it over my fridge. On low you can’t hear it at all unless it’s silent.The only thing that I would recommend you get if you buy this purifier would be a indoor air quality sensor as this machine doesn’t have a air quality sensor built in.Overall 10/10 for the product, 5/10 on the shipping.
