Blueair Classic 605 Air Purifier with HEPASilent Technology for Cleaner Air

Worthing: This is a large, well built, and capable air purifier that works well, is relatively quiet at lower speeds and doesn't require constant intervention. I live in a ~1600 square foot house that is two stories and I run the air purifier on the first floor. This purifier sucks air in one side and blows it out the other which I love compared to previous purifiers I've owned (Blue Air 211+, Medify Air MA-25, etc.) which suck air in from 2 or 4 sides and blow it out the top or another side. Since you only have to worry about two sides having enough clearance it makes it easier to place this air purifier near "stuff" and you can set items on the top if you have to.
The item works very well, even on "low" and keeps the air in my house pretty clean according to both the readout of this unit itself as well as another air quality monitor I own. I still keep a smaller unit in my master bedroom (the Medify Air MA-25) but given how much air this unit moves it's really not necessary. I have not had the unit long enough to need to replace the filters yet so I can't comment on how long they last or whether they're expensive for how long they last.
I would absolutely recommend this unit to...

Josue Martinez: This air purifier has amazing coverage. This one air purifier is enough for my entire apartment. This has helped with my dust allergies tremendously. It can be managed through an application, where you can see the particulate levels and also control the fan speed. It is very quiet in low and has an auto mode. It is very high quality and you can even add a schedule. I have had this filter for a few months now and am extremely happy with its performance.

jz: My 605 Classic just arrived. Big box, but once it’s out it’s not terribly large. Very simple unit, filters come pre-installed. Changing them will be a breeze; lift off the top metal screen, lift filters out, drop in new filters. Takes all of 15-20seconds!!

Very simple & EZ to operate. I skipped the Wi-Fi (can turn it off); I’m not that lazy that I need to control it via an app. It’s all of one button to turn on/off.

Fan is ultra quiet on setting 1 & 2. Fugedda ‘aboud it on fan setting 3. Unusably loud. Can’t hear my TV with fan on 3. Only purpose is to quickly fumigate a large room.

Fan speeds 1 & 2 are quiet enough that you could easily sleep with those speeds selected. I have a BA 211 also and fan speed 2 on that is higher. But now that I’m living in a larger home, I definitely went with BA & the 605.

It’s an impressive unit; steel parts, very well made. Wheels/moves around extremely easy.

I’ll just leave it run constantly on fan speed 2 and I’m sure it’ll work just fine. I found it on sale, 42% off which made me jump to buy it immediately. At that price, it was a no brainer. I see the 605 Classic (and...

Akiiki: I like being able to control it from my iPhone. It is very quiet and it’s blue light is strong enough when the room is dark. I have noticed a lot of relief from my allergies since I started using it. Excellent product.

Margaret Eslinger and Ralph: When set on automatic mode, unit controls all functions perfectly, very happy with it, especially when smoke from forest fires are present.

Michelle MacDonald: Very easy to use and works very well. It is loud on high and whisper quiet on low and medium. It’s helped me tremendously and I’m breathing much easier in my own home which is priceless.

Rbt M: I have severe allergies and will DO ANYTHING. This filter definitely has helped reduce allergens. Number 1 and 2 settings I would say are almost indiscernible , and #3 is like a room fan. TOTALLY acceptable, and I would buy another one for the other side of the house shortly. It is heavy, I have it on a set of wheels, but how can it do its job without the inside motors etc? Excellent product. Incredible packing, I think there were four boxes, like a Matryoshka Russian wooden doll.

JwHw: 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...

Roy: Very good product, setting 1-2 its very silent. Has a big filter. SmokeStop filter is not attched. Connecting to WiFi is a bit tricky.

Have been using it daily, a family member had a constant cough. Using this has completely stopped the cough!! Which is quite incredible.

Has no air quality indicator which is a bit inconvenient as we do not know how well its cleaning. But as a basic air filter you cant get anything better than this for your normal sized bedroom.
