I did a lot of pre purchase research and very happy with my choice to purchase Blue Pure 311+Max. Love the efficiency and operation modes including Night and Auto.
This is my second unit
Great filter. Easy to use. Improved our indoor air quality noticeably.
You can visually see when dust gets accidentally released in the air (my renal unit has crappy metal blinds that gather dust like crazy!) and my 311i+ Max “auto” feature kicks the purifier into high gear to suck it out of the air. I literally saw the dust in the sunlight began to get sucked in toward the purifier like a vortex. Amazing!
I live in a region where climate change has so terribly affected the area, we have destructive wildfires regularly. What was once in a blue moon thing now has become normal to experience multiple every year. I recently moved into 11 miles northwest and in my new city, about 28 miles away from wildfire started. Although my FireWatch app alerted me to the fire it was far enough away and weather conditions were fairly calm so I wasn’t concerned about evacuating at the time & temporarily quieted my notifications for 30 minutes. But then I heard my purifier kick into high gear. Inspecting what was going on causing it to put itself in high gear, I walked to that end of my unit, opened my patio door and slightly smelled the smoke but still didn’t see it. However, my 311i+ Max caught it and cleaned it up in 20 minutes!
I didn’t realize spray deodorant was a problem but my Blueair does. Even spraying it in a second bathroom and waiting a few minutes, if I then walk into my room past my Blueair, it will automatically increase to high to clear out whatever pollutants it’s picking up from my recently sprayed on deodorant. Same when I put my favorite…
I didn’t realize how well this air purifier worked until my Heating and Air people came for my semi-annual check-up. I didn’t need to replace the filter on the furnace because it was clean. I found that amazing and I just put in my new filter in my Blue Air purifier 10 days ago. It lasted almost 9 months.
I have allergies and this has helped enormously.
