Blue Pure 211i Max

It works like a charm. I like that it shows me a number and the chart for what that number represents. I think its an excellent product for what it costs. Would highly recommend it.

Reassuring

We have lots of fires where we live in this confidence building to see the low numbers or no numbers on the machine. Two additional illustrations: Purchased a new microwave and learned that popcorn overcooked set off air purifier! Happy it did. Purchased a new stove. Burned off the manufacturing oils in the oven. It said off the air purifier. Again, happy it did !
