But, it's been on the market for almost 5 years, so it's probably getting replaced so app support may fall behind during the life of ownership if you purchased now.

Since they're run continuous rather than cycled like a standard furnace, the filters will clog up quicker. Rather than the typical 90 days, they should be replaced monthly. Mine get changed when I remember, which is closer to every 3 months, but that's enough improvement in air quality for my needs. Need finer filtration, get a better quality furnace filter.
If that doesn't work for you, then this deal is a good option. Just seems like overkill for most people's needs, and a steep initial investment. Worst case you end up with a budget filter for a guest room, and buy this beast for your master.
You need the air to be squeezed through. Air purifiers are designed with air pressure balance in mind. Anything drawn through the box fan is only a fraction of what is in the air. And only the closest segment of air.
Also that's a huge fire hazard.

An engineering professor at the University of Toronto says a box fan & furnace filter combo works great.

According to the specs, it is very quiet at only 43 dB. Would be great for a classroom even running at high!
However, there are less expensive options out there for similar CFM. The Costco Winix models do ~240 CFM for $100 (on sale). The Honeywell HPA 300 does 300CFM for $210–$250. So buying 2 of those would outperform this, but would be louder.
So while your Blueair Pure 211+ may be better for a bedroom, this unit would be much better for larger spaces.
The purifier works great for those debating. I have 3 cats and I can tell the difference when we aren't running it. Captures lots of hair etc.
