Blue Signature

I have two small coways (meh), Dyson (meh, but very good for heating!), Levoit 600S - very good and just got blueair signature - so far very happy. 

Go to the Blueair website and look at all their air purifiers. Some are on sale for almost $100 less. Look at the new Blue Signature on sale. It has a washable fabric pre-filter, which is great for dusty rooms. I think Blueair purifiers are terrific, and never consider buying any other brands any longer.

BLUEAIR for the win. Saved me twice from getting covid (sick visitors). Just upgraded to the newer Signature version.

It’s honestly so good! I initially started with the 511, 5 years ago and recently just upgraded to the blue signature (during Black Friday) which is the prettiest out of the bunch! lol I’d absolutely get the 311 for our other rooms— gotta wait for another sale tho lol

Check out the Blueaire Signature. Looks like a small side table. You can place small items on it like the small holiday display I have on mine.

I just got my Blueair signature and it’s making a loud clicking motor noise on speed 1. I’m returning it. Not sure if I should buy another one.

I have a blue signature and love it (we got it as a gift), the app is very easy to use and I have noticed an improvement in dust and also my allergies. I was really impressed with its ability to detect what’s in the air - I’ll light a candle about 15 feet away and it’ll kick on. I’ve never had a levoit so can’t speak to that.

Seconding this. I have two Blueairs too. I have a 511i Max also for my bedroom and the new Signature for the living room. Works well and good stats in HA, which is all I really wanted.

This website can help you make a choice. https://housefresh.com/air-purifiers/ Last week the Blueair Signature was on sale and I ended up getting two of them. They have been great so far.

I generally just leave them at 2. They are quiet enough where they are not noticeable. When we have the windows open I turn them up to 3 to help with my allergies. Four is on the louder side and not needed in my home so I rarely use it.

I am sitting next to mine (like 2ft away at ear level) and I can't even hear my device at 1. I would definitely either exchange or return it.

I completely understand how you feel; I've had very similar issues and quite a few questions about air quality and breathing comfort. For me, what really helped was a combination of simple things rather than a single "cure." I use a Blueair Signature air purifier, mainly for fine particles (dust, smoke, candles, cooking fumes). I leave it in automatic mode during the day, and in the evening I switch it to night mode, so it continues to filter silently. I've noticed that it reacts quickly to spikes (for example, with a candle) and that the air becomes clean again quite fast. Before going to sleep, I also always ventilate for 5 to 10 minutes, even in winter. It refreshes the air, lowers the CO₂, and clearly improves breathing during the night. Another thing that helps me a lot, especially when the air is dry or irritating, is gentle nasal irrigation. I simply use isotonic Respimer. No need for a strong rinse: just one squirt in each nostril, head slightly tilted to the side, let it flow naturally, then blow your nose gently. The goal isn't to rinse the sinuses thoroughly, but just to clean and moisturize the mucous membrane, remove particles accumulated during the day, and soothe the nose before bed. Since I've been doing this regularly, I have fewer irritations, I breathe better at night, and I focus much less on numbers or sensors. The air purifier helps, but the surrounding habits really make a difference too. Hang in there, these are topics that can quickly become anxiety-inducing, but with simple and regular actions you can really improve your daily comfort.
