Blueair - Blue Pure 511

We have had one in basically every room for years, and it's made my husband's asthma/allergies non existent at home. He used to have them really badly. We also have two dogs and there's never any fur or smell around the house. It also really cuts down on the amount of dust in the house. I always follow wire cutters recommendations. We have blue air blue pure 511 in most rooms and love it. We've had the coway mighty for close to a decade now. We originally bought it back when we lived in a studio, and it now resides in our main bedroom. This has an automatic setting where it increases speed when it detects air pollutants. It's been really interesting over the years to see what sets it off. Aerosols for makeup, shaking out sheets, cooking without windows open, humidifiers without filters. We've changed what we use in the house based on it because I'm concerned about lung health in general, because of my husband's poor lung health. It also is great for smells around the house, and in general for when you accidentally burn something on the stove, etc. it clears it out a lot faster. We do still open windows to air things out and have an HVAC filter, but this just is makes an additional difference on top of it. But also keep in mind we live in the city and have only one level. That probably makes a difference in whether filters are useful or not. Also my husband and I never transfer illnesses to one another anymore since air filters. Not sure if it's related or not As far as features I recommend getting one that has a night mode and keeping it on so there isn't any extra light pollution in the bedroom.

We have this one in our bedroom https://www.blueair.com/us/shop/air-purifiers/blue-pure-311i-max/3539.html Blue Pure 311i Max for medium rooms! Looking online it looks like they've updated the model a little bit, but looks to be relatively the same! The filter we have on auto subscription is for this one too so couldn't have changed too much. We got the Pure 511 version for our nursery though since it's a pretty small room.

I got this Blue Air one that had high ratings on consumer reports. It sits next to the LR3 between it and the door to our hall. I don’t smell anything. BLUEAIR Air Purifiers for Bedroom... https://www.amazon.com/dp/B08KPJCDN6?ref=ppx_pop_mob_ap_share

Blue air is great, they have a smaller purifier for like 80 bucks. I have the 311 auto but I think the 511 is probably what you're looking for. I run mine on low continuously and it's whisper quiet (especially after initial break in period), medium speed is tolerable. I only run it on high if I'm about to leave the space. Where all these purifiers get you in cost is the new filters.

I’m anti-Levoit right now after previously being a fan of their stuff - I had a Levoit Core 300 that developed a fan whine after a year. Went through the RMA process and they sent me a new one, which developed the same noise within a few months. I have several larger Honeywell purifiers throughout the house which have lasted several years, just wanted a smaller one for this smaller less-used room - been running a Blueair 511 in there for the past 6 months and it seems good so far, and very quiet.

Their CADR is in cubic meters per hour, where most purifiers specify CADR in CFM (cubic feet per minute). Multiple this by about .59 to change to CFM, so it's claiming \~250 cfm. (It's actually 264.) Most air purifiers at this price point (the blueair 411/511, the levoit core 200s) have a CADR of 100-150 CFM. 100 is actually sufficient for the room size (160 square feet) you're mentioning. If it's too good to be true and there's no information about them anywhere, then it usually is :)

I mean.... I mentioned the part about them having no reviews and being at a sketchily low price point of 1/2 to 2/3 the cost of everyone else. There are really only a handful of air purifier brands that have demonstrated reliability, affordability, and effectiveness over several years, and don't dabble in post-apocalyptic/steampunk decor -- coway, levoit, blue air, winix. If you want to pay more, there's iq air, alen air, and a few others. For $110, you could have bought a blue air 511 and almost a 411, a levoit 300, almost a Levoit Vital 100s, or a Winix a231. The winix 5500, the coway 1512, levoit vital 200, and the blueair 311 are all at this CADR, but for closer to $200.

The key here is that this is a brand Costco has carried for years AND sells the replacement filters. I have this model in my son's room and it performs very well. Years ago, I bought (an awesome) BlueAir HEPA air purifier from Costco and they no longer sell the replacement filters. Those filters are crazy expensive, so that purchase turned into quite the "investment".

Having lived in fires and smog. Theres two easy brands to pick: Bluair (more expensive but rock - I have a few) Coway Back up is box fan with hvac filter (check which one for smoke / etc. Good luck!

I have terrible allergies and use Blue Air on every level. Works amazing.

Blue Air. You can wash the outer filter to catch big stuff like hair and pet fur. The inner filters last a while, I use mine for a year before replacing them. If you actually need it for allergies, disregard the automatic settings they offer - their sensors can’t pick up most allergens but rather just cooking smoke or something else really obvious. You want to run it at the highest speed when you’re in the room and one notch lower otherwise.

We have multiple Blue Air and a Coway. Happy with all of them. Frequently available on sale.

Blue Air, there is the internal filter that’s replaceable and out filter that is washable. They come in many sizes. I have them all over the house and it’s majorly helped w allergies and dog smell

I have 3 diff sizes and I bought according to the sq foot reccs

It's absolutely worth it, especially if you have an open top cage. I use a Blue Air and it's fantastic in keeping the farm smell to a minimum. I also open my windows at least once a week and turn on all the fans for an hour to cycle in fresh air.

i love my blueair. i have two cats, one is as floofy as they come, and it keeps up easily. the outside cover is machine washable and i wash it every time i do laundry. my only complaint is the filters are pricey and they’re often sold out during allergy and wildflower season. you can’t find them on their website or amazon or anywhere. and the generic ones are garbage. i’ve learned to keep a couple extra on hand.

Made this small flowchart for a friend who kept sneezing through spring but wouldn’t commit to buying an air purifier Step 1: Identify the enemy Is it pollen? Dust? Pet dander? The ghost of springtime past? Yes, yes, and probably yes. Step 2: Must have criteria for air purifier \- can it actually trap allergens? \- won’t sound like a jet engine in baby’s room? \- easy on maintenance? \- doesn’t cost the soul of your firstborn? (ironic but important) Step 3: I went down the rabbit hole Compared Coway vs Levoit vs Dyson vs Honeywell vs one that looked like a spaceship BUT... nothing could compare to [blueair air purifier](https://rantsreviews.com/dp-B073WJL99W) \- Covers big spaces (so your nursery + more = chill) \- HEPASilent tech is real — gets dust, mold, pollen, pet funk, all of it \- Washable pre filter = less guilt about killing the planet \- Doesn’t wheeze like a dying robot at 2am \- Design lowkey slaps too Step 4: Baby sleeps better. You sneeze less. Partner doesn’t threaten to move to the forest. Life improves. You win!!!
