Blueair Classic 405 Air Purifier for home with HEPASilent Filtration for Allergies, Pets, Viruses, Dust, Asthma, Odors and Smoke, WiFi Enabled, ALEXA compatible- Medium to large rooms

I purchased this unit based on Consumer Report's review of Blue Air products. They are the highest rated brand and in my opinion, comparable in price to competitors. I read a ton of consumer reviews in addition before purchasing. I've been running this unit in my living room for about a week and it's probably a little too soon to tell if it's helping my allergies. I have both seasonal and winter allergies (dander, dust etc...) when the house is closed up. I live in SW Montana so the house is closed up tighter than a drum all winter. Plus, we use wood heat due to the low cost.I started noticing changes in my breathing every winter a few years ago, I was diagnosed with asthma and I am pregnant now so I can't take the usual medication that helps. I'm stuck with Tylenol and other decongestants that are safe but not as effective as I am used to. I basically have my inhaler and a combination of baby safe stuff that doesn't work well. I am so desperate for relief that I just spent almost $1,000 on air purifiers, special bedding etc... to try to get some relief. I basically struggle with sinus headaches, postnasal drip, a constant cough to clear crap out of my throat and chest plus sneezing...a lot of sneezing. I am already sneezing and coughing less but correlation does not prove causation even though it can make you hopeful!As far as noise, literally 0 reviews were useful in helping me judge the actual noise level to expect. While even Consumer Reports dings this unit on high speed for noise, it did the same for almost every other unit as well so apparently it's a "thing" you have to live with. The most helpful thing for me would have been if someone would have used other sounds to compare for each speed so that's what I'm going to do.Low: indiscernible, especially during waking hours and normal household sounds. It's basically silent for all intents and purposes, I can't think of something to even compare it to it's so quiet. I'll probably start running it on low after running it steady 24hrs a day on medium for a week or so. We're doing construction in the house so we have extra dust in the air.Medium: Seriously, my microwave is louder than this unit. Think of an oscillating fan on low. You can hear it but it's not distracting by any means. Honestly, it fades away when I'm working. I'm finishing up my end of semester papers in the living room and the unit is in the dining room and I find it easy to tune out.High: Yeah, you're going to hear it. To me, it sounds like a big ole box fan. Which, yeah...it basically is. However, I can't really think of a reason to run it on high unless you're like me and you set something on fire in the kitchen. It would probably be useful on high to air something out or get rid of a pungent odor quickly. Otherwise, I can't imagine running it on high. Perhaps if you're in a high fire activity area during the summer in which case I'm sure the relief it provides would be worth it. We have our fair share of fires here and I guess I'll find out then if I need to run it on high.As far as effectiveness, when you walk by the unit and it's on medium, you can feel the air moving around the entire unit. I'll take this as a sign that it's working, taking air in and expelling clean air in the process. This unit is ridiculously easy to set up. The filters are already in place you just have to plug it in. If you don't feel like using the app right away, you can run the unit with the hidden controls. I easily set my unit up on my phone with no issue and it appears to be working fine.It is large, be prepared to make room for it. The casters are super easy to roll and the unit isn't overly heavy as much as it is awkward. Once our renovations are finished I'm sure I'll find a nice hiding spot for it. You can't put anything on the top of it though because the top is part of the ventilation system.Like I said, I'm still waiting to see if my breathing improves but so far I'm encouraged. We live in a home built in the early eighties, we use wood heat all winter, the air is notoriously dry here in the winter and we own two dogs that are outside/inside dogs. One is a hypoallergenic poodle and the other is a slightly neurotic, shedding monster aka mini Aussie. The house can have moisture issues in our master bedroom and bath in the winter when it's closed up which we try to manage the best we can. However, I wouldn't be surprised if there is mold present at times in the winter. I've never been allergic to animals in my past nor have I been diagnosed with anything besides seasonal allergies and difficulties in the winter.We experienced no odor issues as other reviews have mentioned. Perhaps they have something present in their home that is reacting with the carbon filters to create the odor? It's hard to say but I'm thankful we have no odor issues with our unit.Hopefully this review is helpful!

Improved Humidifier. I've had similar humidifiers from CVS and Rite Aid over the years $39 if I recall right. They were simple to use, no filter. The only down side of those was they didn't hold enough water or move the mist far enough in a small bedroom. BUT THIS is perfect in our large bedroom. It is quiet and holds enough water for a few days of night time use. We don't wake up all dried out and stuffed up anymore. It is one of the least expensive ones and it works great!

The air purifier works very well...I have it in my movie room that is 14x25 and it had all the dust out if the air in an hour. Three speed setting are good. Speed one I can't hear at all, speed two is almost double the air movement and I can just barley hear. Speed 3 moves a ton of air and is the loudest setting, although I can still watch tv at this setting.The filter is twice as heavy as my old unit, which means more carbon. The replacement filter I bought is the same way.The unit pulls air from the back not the front. Not a big deal unless you plan to out in the corner or against the wall. You will have to pull away from the wall to give it enough room to pull the air.Very well made and the app was very easy to setup. The app works good and I was able to create some schedules where it kick on at high at night when sleeping and then low during the day. It sometimes says not connected in the app but I have found you just wait a couple seconds and then it pops up.Would buy again

I’ve had a Blueair classic 200 series that I got probably 5+ years ago and have run 24 hours a day. It’s quiet even on the high setting in my opinion. From my past job, I would say it’s almost like airplane noise on high. I now added the Wi-Fi capable 480i that I just got today. It must’ve been a return. I got it “like new” for about $100 off in the original packaging, no damage for a fantastic price! It looks like it was never opened just returned so ecstatic about that! So far I’m playing with the auto mode and not sure because I like it to blow usually at medium speed all the time which you can do with but I am just seeing how the auto works. I am seeing that when I cook. It will look like the air quality is bad because of odors and come on hire for a short time, but then return to low which I feel is not as much as I like for a larger room. But it’s probably a matter of me adjusting to it. I opened my trash that I noticed a smelly odor about 15 feet away from my Blueair and the air quality went to moderate from excellent and cleaned the air of the odors and then went back to excellent. Impressed so far but I don’t know if I’ll use the Wi-Fi -it’s very easy to turn off , with holding down the Wi-Fi button and the filter button for about three seconds simultaneously. You can turn it right back on again by pressing the Wi-Fi button. What I really dislike about the Wi-Fi is it tells you you must put in your precise location in order to use all of the functions in the app and if you look at that I do not want my address and name in there and I can see everyone in my city listed that has one of these. so it looks like I probably will not be using all of the Wi-Fi functions. You can connect to Wi-Fi but you can’t use the app without your location??! Sorry I don’t need to be tracked that much! It is almost the same size as my other one but for larger rooms and the filters do look different and are a bit more expensive. But this one also has the carbon which is more expensive for the 200 series than the basic. I noticed some one said in a review that they wish the duo filters were separate, but you can vacuum them out and keep them going a little longer if you want. You can tell by the color when it’s time to exchange-it’s not quite as white and can go towards a gray ,My 200 has been flawless and I’m hoping this newer version will also. This one’s in the living room the other is in the bedroom. I don’t wake up congested when I have it in my room where I used to wake up several times a night and not be able to breathe out of at least one side. I do have a lot of allergies and there’s a lot of pollen in the air where I live now and it keeps my air “excellent“. Better for everyone including the pets! Really glad I finally bit the bullet and got a second one now that I live in a larger place , PS these are heavy metal but that’s a good thing and medical quality.
