Blueair - Pure 411 Auto

Yeah it’s totally fine. I used a 411 auto back in the day. Similar specs and performance. It worked great for my bedroom. It was damaged in a flood incident that’s why I don’t have it anymore but the filters lasted a while. They were definitely sucking up dust/pollen. And I did particularly enjoy that their filters are recyclable. Most true HEPAs aren’t. HEPA status of a filter is a lot less relevant than CADR of the unit in the space it’s being used in.

Ah, that's too bad. We've got a bunch of 411s and they're all still going strong. They're fairly simple, which is I suspect also why they're relatively reliable. I wonder if it's repairable honestly. Like maybe something just came loose inside there. I actually couldn't remember exactly when I bought all of ours so I looked it up in my Amazon history. We have three 411s that are all 8 years old now and still going. We have two 211+ models and they're 7 years old. And then 3 411 Autos that are now 3 years old. So far no problems with any of them running all day every day.

I have a blue air 411a that i got for a steal. I've seen on here they can have issues later on but after a year, it's doing ok. It's pretty solid but you have to make sure to keep your home clean and dust free. I ended up switching back to a bagged vacuum and dust twice a week. An air purifier won't help if you aren't preventing dander build up too. Edit to add: i only paid $70 for it new. You'll probably want to invest in a better model that circulates air more often.

The only thing that will stop dust from your PC is you cleaning your PC and cleaning your house. Regularly. I have a 411 for over a year, and it's been fine. Edit for clarity

I can't say on that purifier (i have a blue air 411a), but a purifier and hot steaming your fabrics really help. Anything over 200F kills dust mites. Get the carpets, couch, curtains, etc. It really helped my dust mite allergies.

I also have always coveted the coway airmega, which has remained high in rankings (though can’t fully ‘trust’ any of them) but also above $200. How much are replacement filters? I bought my blueair 411 (not auto) 2019 for $100 and it remained high in all the rankings until 2022 when other stuff creeped up. My model remains less than $150 and Manufacturer’s replacement filters are $25 a piece but external prefilter cleaning by vacuuming and/or washing makes them last way longer. And they have prettier pre filters than the standard bright spandex ones that come w it. Does airmega have a ‘prefilter’?

I just drafted super long reply re blueair 411 and 411 autos. Light (easy to travel with), easy to use, external filter, have had since 2019 and hasn’t broken despite getting kicked down not infrequently on carpet and hardwood floors. Negatives is bright light on top button, I don’t use the app, and button on the auto models is more finicky than on original model. By reading through this I am rechecked things and it has ‘electrostatic’ as well as HEPA-type filtration (they claim theirs is better). I understood electrostatic was the only thing that could actually clean the air like for gasses or VOCs, not just remove particles. Looking back and re-researching, it looks like anything electrostatic will produce at least some undectectable ozone. So, well I’ll-be-damn! I wanted to not have to worry about ozone! I have never detected an ozone smell like from our previous germ guardian, but dang.

Plus one for this. I have two blue air 411s in bedrooms and they are very good and new filters aren’t too expensive either. 

I also have two blue air 411 for each bedroom. Can't recommend them enough. They just do the job and filters are pretty cheap. 

I second the Blueair purifiers. I have the 211+ non auto in my living room and the smaller versions in my bedrooms. I've had the 211+ running for about ten years and still going strong. The smaller ones I had to replace recently. I got the table top Mini Max through Costco in a 2-pack and I regret that size. I'll get the smaller standing 411 ones again next time.

Blue air junk? I have been using blue air for a decade and got one for each of my staff conference rooms during the COVID response - none of us got sick and we were in person for over a year. These things have been running for years daily and I’m a fan…

We have been using Blue Air for over a decade and have been happy with them. Have the 411, the pure fan, and our first one the 400. Had a couple fan issues over the years but customer service has been good so far.

I think anything name brand with a hepa filter will be fine for you. a small one is fine if its for a bedroom. I adopted a cat and my room began to smell like a petsmart. I was lucky enough to find a $100 air purifier on Facebook market for like 20 bucks, my room smells completely clean and neutral now. I firmly believe its a big difference and helps make your room a more enjoyable space. if you dont wanna do any browsing, I use the blue 411 and I like it a lot.

I have a 411 and it died (wouldn’t run, connect to anything, blinking red light). Their customer support was very bad, multiple times just stopped responding to me until it was out of warranty. Because I had old case numbers they eventually admitted it was broken and reported within warranty and replaced it, but I wished I’d’ve got it from Costco so I could just return it there instead. 

Another vote for Blueair. I’ve had a 411 and two smaller ones running continuously for a few years now and they help with dust, dander, and lessening mildew. The app is pretty cool. The soft white noise is perfect for sleeping. Plus I run HVAC filtration every hour.
