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.

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

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

Blueair Signature purifiers are excellent. The Hepa rating is not necessarily the main factor … what is something is better than hepa… why ignore those purifiers ? Happy with Blueair here.

Have three Blueair purifiers, but not those models. Reading briefly at the site, they both look great for large rooms, but it looks like the Signature does a more superior job controlling odors. You can check that out yourself at the Blueair website. Always check the website, too, for their sales.

The Signature also has pelleted carbon wh

More of a subjective impression. I’m super sensitive to smell, so I notice “bad air” even before any of those purifiers turn on (when in auto mode). If I should recommend something, I’d say go for the largest model you can get (at a reasonable price) and get one with wifi connection. Filter replacem

I have the Winix from Costco and the Blueair Signature SP4i. IMO, they work about the same. The app for the Blueair has a feature I like, where it can be set to know when you’ll be arriving home. It uses your phone’s location to do this. I don’t want it running for the 10+ hours that the house is em

Get an air purifier with a HEPA filter. All of them have a fan inside. The HEPA filter can remove microscopic particles. I have ridiculous allergies and have had 6 sinus surgeries. As a result, I've used several different air purifiers over the years to remove dust from the air. BlueAir is the only
