Best praise vs top criticism for Blueair Blue Pure 211i Max

Best Praise

At some point one unit can only do so much, when areas and airflow are this big, people/companies consider tailored ventilation/filtration systems. I think the ProX and the blueair 211i max are the best candidates you will find before having to consider a more complex solution. There is a third option I just remembered, the smartair blast mk ii. I believe a third version is coming up soon? You could reach the vendor to confirm. I personally don't like their units, mostly because of the aesthetics but the numbers they showcase are very good. Nothing can match the price to airflow of the blueair unit though, especially if you are in the US/Canada where blueair is super cheap.

I'm also liking Coway. I got 3 of the 1512hh for the bedrooms and so far I'm linking them. Then I got the blueair 211i max and realized that the fabric is the pre-filter. I'm in Los Angeles so I got it because of the wildfires and possible asbestos but I'll be returning it because of this design. I didn't it try at, just took it out, saw how it's all attached together and tomorrow I'll send it back. Waste of time. I now got a Coway mega 1216l I hope it works better, it was only $100
