Q: QuestionIf this Blueair purifier is set in automatic, it stays on at all times. Should it be turned off at intervals, or is it ok to keep it running at all times 24/7? Thank you.

Asked 1 year ago by RamonS.

• A:Answer Thank you for your interest in Blueair! Yes, your Blue Pure 311i Max air purifier can operate 24/7, and in fact, continuous use is recommended — especially when set to Auto mode, which automatically adjusts the fan speed based on real-time air quality. This helps maintain optimal indoor conditions.

Q: QuestionHow good is this unit for removing dust and rate of air circulation

Asked 2 years ago by Bb.

• A:Answer I have one cat, hardwood floors and two flat-weave wool carpets, a central HVAC system that is regularly serviced AND I vacuum and dust *everything* at least weekly. If I don't, there's a visible layer of dust on everything (this was true even before I adopted a cat). So: I purchased this unit three weeks ago in the hopes that it would reduce the dust so that I could go longer in between flat-out cleaning sprees-- and also so that my cat's allergies might improve. (Yeah, you read that right: my cat is pretty severely allergic to dust mites and I figured this air purifier is less expensive than a very unhappy cat and repeated vet visits.) So how's it going? The good: rate of air circulation is amazing, truly, especially on setting #2 or 3--and my place feels *fresher* when running it on those settings, if that makes sense. Running it at setting 3 while cooking is also *helpful* in keeping the place smelling fresh, but don't expect miracles-- maybe 50% better? Also: running it 24/7 on setting 2 or 3 isn't practical--it's both loud and windy. I generally leave it on Auto. The bad: my place is still seriously dusty. With the same amount of cat hair forming the same tumbleweeds. Honestly, I didn't notice much improvement on dust or hair, which was v disappointing. Lastly: my cat might be itching less? hard to tell if it's helping but it's not hurting. *My* allergies (pet dander, dust mites) seem to be exactly the same as before (I need benadryl ~2x week, so they aren't severe, ymmv). Do I regret my purchase? No. Do I wish this machine would improve the dust situation: yes.

Q: QuestionCan anybody say if Blueair air purifiers have True HEPA filters? It says HEPASilent but is it the same thing? Their replacement filters do not seem to mention HEPA at all in the description. My Levoit units were stripped of HEPA labeling.
