A: The Blue Pure 311i+ Max air purifier cleans up to 1,116sqft large space in 30min on high and has a Clean Air Delivery Rate (CADR) of 300 for fine smoke particles, dust and pollen. The Blue Pure 311i Max air purifier cleans up to 929sqft space in 30min on high. This air purifier has a Clean Air Delivery Rate (CADR) of 250 for fine smoke particles, dust and pollen.
A: 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.
A: Thank you for your interest in Blueair! Our air purifiers feature unique HEPASilent™ technology, which combines traditional mechanical filtration with electrostatic charging to clean the air faster, produce more clean air, and do so much more quietly than conventional HEPA purifiers. This innovative technology, ensures maximum filtration with minimal noise, delivering clean, filtered air to your room as quickly as possible.
Q: How good is this unit for removing dust and rate of air circulation
A: 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.
A: Thank you for your interest in Blueair! The Blue Pure 311i Max quickly cleans 439 sq. ft. in 12.5 minutes and 1,054 sq. ft. in 30 minutes. We recommend placing it on the floor where you spend the most time. For best results, consider having an air purifier on each floor to maintain consistent air quality throughout your home.
Q: Does this have a HEPA filter
A: Yes, it does have a hepa filter and what I like about the air purifier is that it has an outer pre filter which can be machine or hand washed allowing your hepa filter to last a little longer.
Q: Do you have to use the app?
A: Thank you for your question! You do not need to use the Blueair app to operate the Blue Pure 311i Max. The air purifier has a simple, two-button control panel on the unit itself. You can use the On/Standby button to power the purifier on or off, and use the Fan Speed button to switch between modes and adjust the airflow. The purifier offers four fan speeds—with Night Mode being the quietest setting and Speed 3 being the highest.
A: Thank you for your interest in Blueair!
