Thread: DIY air purefier and some interesting charts

Some other threads here on the same subject:

Improvised Ambient Air Filter

researching room air filter - Corsi-Rosenthal box- replacin Merv 13- MPR 1800 or 1900

Two downsides about using an axial fan are;

They'll move a lot of air when the filters are clean but much less when the filters clog up. So either be prepared to clean filters often OR use something like a centrifugal fan. I'd like to see the same graph after say 25 hours of use.

Axial fans make a lot of noise - I wouldn't want one running for many minutes in my workshop.

I serious doubt we could get the same parts here in Oz for US$50, I'd expect something like AUD$150

Capture the dust at the machine because catching it after it is in the air is admitting your DE system is not up to the task. Once it is in the air you start to breathe it in and I thought that avoiding breathing dust was the goal of dust extraction.
