One of my friend’s husband has a lot of allergies. Throughout their house, they have these huge air purifiers made by Blueair. They are also expensive.
When I bought a Blueair several years ago, I purchased one of their newer cylindrical air purifiers and used it a lot. I believe it was the 411 Auto model for medium room. At the time, I also bought a replacement filter, which I finally used today. The 411 Auto’s fan was stuck on high speed which indicated that I need to replace the filter.
The top one is the old filter, and the bottom one is the replacement. I think that is pretty good proof of the air purifier’s effectiveness. Right now, I am sneezing up a storm just from replacing the filter. For Cyber Monday, I had purchased another unit, but got the model wrong. I thought 311 was the same size so I bought a 311i Max. The “i” lets you connect the unit to an app via Bluetooth and allows for Alexa integration. It was bigger than I thought.
The old 411 Auto is naked because the outer cloth enclosure is drying after washing. That was pretty gross too. I think I will leave the huge unit in my bedroom. Since the sale is still on, I purchased two 411i Max units for my two offices. I spend a lot of time upstairs in my house and since it is very dusty, additional air purifiers should help the air quality. Here is the air quality display from the app.
supposedly my room was at 120 for PMI 2.5 and now it is only 24. The gray line is outside, which is currently 4.
