Blueair signature auto mode
Personally, I would set the purifier to the highest airflow speed whose noise levels you can tolerate. Unless the Blueair Signature is already hugely oversized for the room or space, the "low" airflow speed might be too low. Unfortunately most purifier brands do not list Clean Air Delivery Rates (CA

User feedback on the Blueair signature
I just got a blueair signature used from Amazon. It was marked mint in box but it seems loud at the lowest fan speed. I measured it at 32db at fan speed 1. There’s also a smell coming from it, like an air freshener. I’m guessing it’s embedded from the home it was used in previously. I’ll give it ano

Smart Air Blast Mk II vs. Coway Airmega ProX
Have you considered a few different smaller units instead of one big unit? It’s a large space and normally you get better coverage and flow from multiple units. It would also keep the noise down because you could run them all on the lower setting. Also a good idea, and yes I did consisder that, sinc

Help! I suffer from allergic rhinitis, doctor told me to buy air purifier from brands specifically dyson or Rowena or teqoya. People say those brands not good for price . I don’t know what to buy anymore . I spent 3 hours about what to buy. please help me 😢
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, sm

Yes, the noise is problematic. But worse: On their European Blueair website you cannot find filters for Blueair Signature. And Blueair Support is non responsive for more than one month. Consider this before buying Blueair products

Air purifier to address upper airway resistance during sleep?
That's a MUCH better response that the first one you gave me, since it actually has some substance, rather than just calling something "shit". So let's talk. Your point about a good seal being needed to keep the fan blades from getting dirty is an excellent one. Do all the major purifiers (Coway, Wi

Air purifier to address upper airway resistance during sleep?
That's not what the data shows. I've not tried the Alen, but I've tried several other air purifies, and have found the reviews on Consumer Reports and HouseFresh.com to be accurate. And based on those reviews there are other units that provide less noise for the same clearance rate. Specifically:SPE
