There was a problem filtering reviews right now. Please try again later.
First, the government CADR rating always has three levels that represent different *size* particles. They name them Dust, Pollen, and Smoke to represent big, medium, and tiny particles (of any kind!). The smallest, "Smoke", represent those tiny HEPA particles such as many allergens. Therefore, if you are shopping for a HEPA filter, you should only focus on the Smoke CADR results.
The second thing to know is that the government believes people with bad allergies need air exchanged in the room 4-5x per hour, and non-allergy sufferers 2x per hour, to make it worth it. Anything lower and the particles may fall to the ground on their own, or you may just not feel a difference. (Once they fall, I recommend a vacuum with a HEPA filter such as Miele). Their calculation includes an open door to another room, and results get much better with a closed door, but you still need fresh air so you don’t get overwhelmed with carbon dioxide imbalance so keep your door open a little.
Finally, CADR is calculated on max fan speed. NOBODY uses their air filter on max, lets face it!! In fact, my goal is to run my air filter on low because I know I can totally live with it no problem.
So now begin your shopping. Find the brands you trust or heard good word of mouth, and visit their websites and download their manuals. There you will usually find the CADR listed and the CFM output at different fan speeds. If only one CFM is listed it is for max speed, so you can look at the power use of the fan and calculate the CFM of different speeds proportionately. For example if the low power setting is 1/3 of the max, you are probably getting 1/3 of the advertised CFM on the low fan speed.
Take the CFM output from Smoke listed in the manual and divide it into the cubic feet of your room. The blue air Classic 205 says low fan speed outputs 75 CFM for smoke sized particles. (Again, smoke size are the HEPA particles that matter). My bedroom is 12 x 12 x 8’, so I divide 75 CFM (low output) into (12*12*8) 1152, and I get about 15. This means it takes 15 minutes to clean the air. Per hour, I will therefore get 4 air exchanges. Perfect! I never have to go higher than low fan speed.
Using this method, I discovered the Rabbit Air is totally useless on almost all settings. Of course people will say the low setting is quiet - its not getting the job done whatsoever. It needed a room so small nobody would live in. So make sure to use this formula and guesstimate or calculate the room you will use it in and the speed you will use. Don’t let them trick you! You may need to buy a larger air filter if you want the lower speeds to be practical. Some brands are pure marketing, and are useless on low speeds.
Finally, the filter replacement usually follows the same rule of max fan speed and 24/7 use. Blue Air says I need to replace it in 6 months. Since I run mine 12 hours per day (overnight) on low, I can calculate the proportion. 75 CFM is 35% of the highest setting 220 CFM, so running it 24/7 would mean I don’t change the filter for about 17 months. Since I will run it half the day, I don’t change it for 35 months! Sounds right; if you google for when to change HEPA filters it says they “typically” need to be changed every 3-5 years. Boom. Saved myself a fortune.
So far, the Blue Air is working great and has a smooth quiet sound. I will give it 5 stars if nothing goes wrong over time.
Hopefully this helps you. Do your own due diligence and good luck
Update : After a year it is working the same as when I bought it so I moved to 5 stars. The app sometimes causes some trouble. I do not like companies that make you connect to the internet because they scrape your data. I believe the EULA says they upload your data to their servers which likely means it gets in giant correlative databases and sell it to unseen third parties, which is the basic business plan of Silicon Valley. For example, maybe people who live in Los Angeles who have their air filter turn on at bedtime who also recently bought fancy cheese are more likely to own a Tesla. This is the how Google and Facebook work and anyone who scrapes your data. I cannot be sure Blue Air does its well known companies are dying to get into your house (Google purchased Nest for this reason).
I also wish I bought the smokestop filter because many times toxic smells came up such as weed killer accidentally used outside etc.
Unfortunately, both the Blueair 205 and Blueair 203 emitted a pesticide-like chemical smell as soon as I turned them on. The smell from the Blueair 203 was unbearable -- it smelled like I was in a chemical factory. The smell from the Blueair 205 was more subtle, but still disturbing.
I hope Blueair can address this issue -- is it a manufacturing/design decision, is it related to the warehouses where the new units are stored and shipped, or what?
The Blueair Friend app to run it SUCKS. They want way too much info and address info and this and that and this and that just to be comprehensive or stalk you or aquire saleable data on you, or, target you for a barrage of focused marketing products. Anyway, too many questions. All I wanted was to be able to control the schedule remotely and get alerts if the filter needs replaced. Keep It Simple, Stupid! It’s a friggin’ air filter. In the end, after getting so pissed at the invasive app, I just manually left the machine on medium and walked away.
My one and only complaint is the WiFi connectivity and mobile app (Android version, not sure if it applies to iOS as well.) Learn from my pain: While not documented anywhere, these filters support only 2.4 Ghz wifi. If your phone is on a 5 Ghz band, change it before attempting to pair (you can change it back once your filters are on the network.) The app has a ridiculously bad pairing experience and will appear to not work at all -- be patient! There is a firmware update happening at first, although the app displays zero indication of such. You'll know things are working if you hear the filter turn off and back on after a few minutes. I ended up killing and restarting my app after that happened and found the filter was paired and ready to be renamed & configured. It's too bad the only way to set up Night Mode or change the front LED brightness is via the app, because if I wasn't a technology person I'd likely have thrown this all out the window. The initial app experience really is that bad -- the fact that someone tested and signed off on it is incredible, especially for the high price these products demand.
The online extended warranty registration is also awful on the website. It's hosted by a 3rd party and has a form that mixed everything up at the end; I have no idea if it worked. I'll try again via the mobile app later.
UPDATE 2/4/2018: Now this device has started beeping irregularly, very faintly, and keeping us up at night. I just tried to submit a support request on their website and got the response "There was a problem with your form submission. Please wait 2592000 seconds and try again." I'm starting to think this company has no reliable grasp on technology and am not sure I can recommend anyone purchase their products until they get their act together.

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.
I gave 3 stars because I ordered this big machine for quietness and it didn't meet my expectations.
So seriously recommended ... and buy the replacement filters on eBay from the States ... a pack of 10 costs about the same as a single filter in the UK, and it's whilst using one of the replacement filters that I did the above measurements. We find the filters last about half a year if the machine is running all day long, even on low at night ...and giving them a hoover regularly is quite an eye-opener just to see how much crud the filters visibly collect.
