Looks like what they used in Apollo 13.

Those fans flow a lot of air but not much "pressure".  To improve efficiency, you can stack 2 pieces of filter and use 1 fan.  That'd improve the CADR - clean air delivery rate.

We have 2 of them that we built. But we used the Xiaomi filters.

 

BTW, the only place you can get those Hatari fans (same model) are Global House as Home Pro is sold out of them everywhere in Thailand. Global House had good stock as of last Thursday.

If you guys know how to buy from Taobao, just get one of those from China.   You can get 6pcs of them and it wouldn't take up much space nor cost too much.   CADR would not be high, but it's cheap so you can get half a dozen or so.

BTW, other than relatively low CADR, these things are also loud.  So low airflow + loud.

So be forewarned first.   But if you want it cheap and you want a bunch of them, then this is it.

Not really cheap, but performance is crazy.  Turn your house into near cleanroom with 2 of these?  

Positive pressure chamber.
