Description

Blue Pure 511i Max HEPASilent smart air purifier quickly cleans up to 465sqft living space in 30min or 193 sqft in about 12.5min on high. Independently evaluated for safety standards and third-party tested for performance as part of the AHAM Verifide Program for air cleaners, this air purifier has a Clean Air Delivery Rate (CADR) of 125 for fine smoke particles, dust and pollen. Get more out of the filter thanks to our proprietary RealTrack algorithm where fan speed, usage time and pollution levels are used to calculate exactly how dirty the filter is based on actual usage and tells you more accurately when to replace it within 9 months.

*Comparing pollen CADR on high fan speed (Blue Pure 411a Max & 411i Max vs. Blue 411 Auto), other units may vary.Based on AHAM maximum allowable certified rating which may vary from the AHAM seal claimed valued.Noise refers to the dB(A) difference in acoustic power. **When similar CADR was measured, Blueair models with mechanical and electrostatic filtration achieved less noise with less energy than same models with only H13 HEPA mechanical filtration. ***Tested PM 2.5 (0.1 - 2.5 microns) up to 90min in a 30m3 room. Tested to remove min. 99.9% of S. aureus, K. pneumoniae, P. aeruginosa, MS2, E.Coli, H1N1, A.Niger.

    Auto Mode Limited to 2.5PM Particles

    The product description is misleading because nowhere does it mention that auto mode only activates when the particle sensor detects PM2.5 particles. So if you’re concerned about smaller particles like smoke, viruses, and bacteria, which are PM1, this purifier won’t automatically filter them. I plan to return it.
    1 reply from Blueair Support Team team - 18 days ago
    Thank you for taking the time to leave a review. We’re sorry for the confusion and appreciate you sharing this feedback. The 511i Max filters are designed to capture particles smaller than PM2.5, including smoke, bacteria, and viruses. As you mentioned, Auto mode is triggered by the unit’s PM2.5 sensor, which adjusts performance based on those readings specifically. We understand this may not have been clearly communicated and apologize for any frustration. Your feedback will be shared with our team, and we encourage you to reach out to our support team and reference this review if you’d like help finding a better fit.

    Small but Mighty!

    I love my 511i! I really have enjoyed using this product. I find the app super simple and convenient. I look forward being able to watch the light go from red to blue and show me in real time how clean my air is becoming. I have also noticed less congestion. We live / rent an older house and the air quality is not as good. I will be picking up a couple of more units here soon to help the whole house be a bit fresher and cleaner air for us to breathe!

    Great purifier wifi not so great

    [This review was collected as part of a promotion.] I do like this a lot. It is so quiet and barely uses much energy. Really noticed a difference in air quality in the basement since we put it out. But heres the thing the wifi set up isn't the greatest. I get why they would only want it on not the full throttle wifi but I dont have the option for wifi splitting so it just purifies rhe air really well. Can't really read anything on the air quality.

    For when its like someone kicks up dirt and suddenly you cant breathe anymore without cleaner air.

    I had to buy this. And it helps and it makes me feel so snobby about air quality but i got so self conscious and aware about the particulate matter and household level of pollution it’s like I couldn’t breath anymore and was forced to purchase things.

    Clean Air!

    As a first time buyer I’m very impressed with my 511i, unlike most other brand such as Shark, Blueair has the app that works great and it’s very convenient. Only down side is that after some time the device gets bit dirty and requires me to clean more often then usual. But least I know it’s doing exactly what it’s intended to do! Overall the 511i Max makes a great air purifier for any bedroom or nursing room!

    fabric sleeves and coverings

    my last blue air the motor burned up due to the fabric cover making it overheat. I returned it for that reason, and also the fabric cover is attached by a screw instead of just slipping it over it, both of which are not ok. also I would want an air purifier, not a digital anxiety, but just and on and off switch.

    Very Effective

    Recommended by Consumer Reports and -as usual- CR knows. Quiet, small, nice looking. The very first morning I awoke with noticeably less congestion. Money well spent.
