Blueair - Blue Pure 211i Max

We love our blueair also. Got a dog a month ago and happy to hear from guests our house doesn't have a dog smell.

There's also the Winix D360/480 series as a Home Depot exclusive, which doesn't have ionizers and has a pretty high CADR rate. I don't think there are after-market filters but Winix said they continue to manufacture filters for 10 years after so maybe you won't have problems. I'm eyeing it. Honestly my first air purifier was BlueAir and I loved it. Dead silent on the first setting (I think having a vertical fan helps), and I could run it on the high setting all day. I have birds and had no idea about the ionizer though. I've gone through one Honeywell which made my room smell like a plastic pool toy, and I'm not so happy with the return-replacement either, I ran it on turbo today and got a pretty big headache and felt like I was having trouble breathing, which sounds insane but it stopped when I turned it off. I'm almost tempted to just go get another BlueAir and remove the ionizer manually, but I also know that their CADRs are based off of ionizer on, and the larger sizes have significantly more expensive filters.

It helps a lot. I bought it due to smoke but I'm happy to get rid of cooking and dog smells. I have one from Blueair.

We run 3 in our house, one in the main living area (diy pc fan with hvac filters), and one in each bedroom (blue air brand or something, I think). Also consider plastic on leaky windows (cheap sliders).

We have a few Blue Air, 4 of them. They are expensive but worth the price for me. The app works great and the filter replacements are a breeze (filters also last). They also don't look stupid which is nice. You can replace HVAC filters with basic MERV5 cheap ones as well. This helps the furnace and AC run better with less restrictive airflow. Big BlueAir guy.

We are a household full of asthmatics with allergies. We have 4 BlueAir purifiers and I cannot recommend them enough.

Blue air. My wife suffers of airborne allergies, and these air purifiers practically eliminated her allergy episodes at home. We know they worked since a couple of times we have tried generic filter replacements and my wife allergies were back, but disappear again as soon as we bought the original brand name filter replacement.

We have the Blue pure 511 for our bedroom and the Blue pure 211i Max for of living room-kitchen (open concept).

Do not buy an Alen, they are not worth the money. I have two Alen and one Blueair purifier. The BlueAir is better and was cheaper.

You say costs don't matter, but what does that mean? There are devices for thousands of dollars out there, and you'd need multiple in a home. My general suggestion is to find a balance between *total cost* (initial, plus ongoing filters, plus electricity) so you can maximize the benefit and not feel pinched. Wirecutter previously did some studies on total costs - you can try to find them online, but it's been some years. If you really have no cost, just get the largest air purifier you can fit for each room and run it at the highest speed. Your home may feel like a wind tunnel, and that means it's working. For most people, Blue Air is a good balance in these various aspects. They are affordable up front, filters from the OEM aren't too bad (and generics are available on Amazon), and they have an outer washable filter (so you don't waste the expensive inner one on say, pet hair, etc.). If it were me, I'd get a large one for the room I sleep in, and at least one or two others. Ignore any automatic sensor based setting they offer. At night, or when you're in the room, you want it on the highest setting possible, and during the day, turn it down just one notch. You want the air flow to circulate and air to essentially be "scrubbed" by the filters. Remember this is only a secondary or tertiary method of cleaning in terms of priorities. Your best bang for your buck is washing your bedding weekly (including the comforter) in unscented detergent, vacuuming or sweeping, and having good airflow in your home to prevent dust and mold build up (leave bathroom and closet doors open). Use your A/C generously to keep humidity levels down in the humid months and for the sake of your sinuses, use a humidifier in the dry cold winter months if your climate has them.

Yes we use Blueair and they make a huge difference especially with dog related smells or puppy accidents. Just make sure you get an air purifier that is built for the size room you will be putting it in. Also account for filter replacement costs.

Blueair has been awesome for our basement, dogs, cats, sometimes chickens and always a burning fire for the wood stove and you would honestly have no idea all of that was going on. I wfh in the basement sometimes and I could tell that without that I was feeling gunky. Buying it made a huge difference!

I have a BlueAir and love it. Highly rated on consumer reports too

I'm also liking Coway. I got 3 of the 1512hh for the bedrooms and so far I'm linking them. Then I got the blueair 211i max and realized that the fabric is the pre-filter. I'm in Los Angeles so I got it because of the wildfires and possible asbestos but I'll be returning it because of this design. I didn't it try at, just took it out, saw how it's all attached together and tomorrow I'll send it back. Waste of time. I now got a Coway mega 1216l I hope it works better, it was only $100

I've been happy with my Blueair purifiers

I also have two blue air purifiers for large rooms. 2 story house. Blue Pure 211i Max Some limited information through the HA integration. There purifiers were rated top at consumer reports and we are very happy with them. No more nasty dog smell in our bedroom.

Blueair , really worth considering.

I have a few Levoit the same size as this one. I don't really care for them compared to the Winix and Blue Air ones I have.

I had a Blueair for a while and they're nice. But I don't like they have an ionizer that you can't disable. Ionizers create ozone, and when ozone reacts with different molecules it creates all kinds of new compounds that can't be predicted. Would highly recommend the Homechemistry playlist on the Home Performance YouTube channel [https://youtu.be/J2iHOCI2hz4](https://youtu.be/J2iHOCI2hz4) My personal favourite air purifier is this one. [https://www.cleanairkits.com/products/luggables-international-california-and-canada?variant=45663048270124](https://www.cleanairkits.com/products/luggables-international-california-and-canada?variant=45663048270124) Nothing comes close to the cleaning performance and low noise ratio of these devices. And since they use standard HVAC filters and PC fans, the filter replacement and power consumption is much cheaper. Here is a video review of this device [https://youtu.be/b2EsBtZEc68](https://youtu.be/b2EsBtZEc68)

Only some blue air models have ionizers. ~~Most/the most common ones do not.~~ The CADR for the 211i max (which I only pick because I have) does not have an ionizer and still rates ~4x a single Merv 11 filter on a box fan. I still think the Merv on a box fan is great. I only use BlueAir because I know it's effective while also being pretty. I also like the pre-filter for pet hair. Edit: I have learned that it apparently does have an ionizer, but, it's CARB compliant and has passed many other tests that certify it's not producing ozone in any amount that could possibly be dangerous. I think people just want to dunk on it (and use words like ionizing [which we should be concerned about] with no nuance) because they're expensive. But it still works very well and is safe.

Yes I know those are really good but they're so expensive. I don't really care where they're made but I just really don't like the idea of that stupid machine washable fabric as a pre-filter

Blue air. I have 2 and love them.

Came here to recommend Blueair. Their app is nice too

I also have 3 dumb air purifiers from BlueAir and they work great on smart plugs

BlueAir! They have a government id.me discount too.

? Yes. The blue air air filters have a really nice app showing PPM, when filters need replacing, control the speed etc. it's a nice app.

Did you like it so far? I've saw one at BJ's and was thinking of getting one. I have Blueair but it's old (5 years now), so I'm kind of torn between these two.

>I've done some research online There is a rabbit hole to go down comparing filter single pass capture-rates and clean air delivery rates. It is possible that a couple of [DIY Corsi-Rosenthal boxes](https://www.webmd.com/allergies/corsi-rosenthal-box) will be more effective, or more cost-effective, than a commercial HEPA filter. Especially for use while doing renovations that generate dust, Where we live, there are days when the AQI gets up to "Health alert: The risk of health effects is increased for everyone." and it is sometimes at "...members of sensitive groups may experience more serious health effects." for multiple days. We just replaced one of our Blueair air purifiers (under warranty). The replacement has a particulate counter that controls the motor when set to "auto". When we fry something on the stove-top -- two rooms and two closed doors away -- it sounds like it is trying to get up to airspeed. I know the Blueair makes difference in the way things *smell* on days when the air outside is purple, so it is not completely ineffective. OTOH, the two Blueair purifiers are on all the time and we have ***not*** noticed a decrease in the rate at which dust accumulates on the woodwork in the house. I've thought of getting an air-quality monitor to try to quantify the efficacy of the Blueair purifiers, but I am not sure what I would do with the information. I've got two double-tall Corsi-Rosenthal filters -- one in the Attic and one in the basement -- that I run when the air gets really bad or when I know I am going to be working in one of those spaces for a long time. The C-R boxes move a lot of air, and do really cut down on the big-enough-to-see dust circulating in the air and piling up on surfaces. * Eykelbosh, A.

I've been super happy with my BlueAirs.

I have a few honeywell hepa filters, a Blueair (for the built in air quality sensor), and 2 Oreck truman cell filters. The Orecks are by far the best but you have to find used ones.

Levoit are good entry purifiers with a lot of feedback on Amazon. Then I like Blueair too.
