Default Fine Dust

I check my Jet air filter and was surprised how much stuff floats around. The blue is the spot I cleaned on the filter the rest is the dust that just builds up.

Dust particles of the size of bacteria gets through most filters including face masks. They can be very dangerous, whether they are fly ash from coal-fired power plants or wood particles from routers, table saws, planers, etc.

I don't think you can have enough filtering . I should add a ceiling mount one while I'm at it .
If I take my mask off 5 minutes after the last cut , I start coughing . Goes to show you how much lingers in the air

Hi Ed, I have 2-Jet air filtrations devices mounted from the ceiling in my shop. The one farthest from the work area runs all the time, and I have to replace the filter more often. They do indeed pick up a lot of dust. I turn the other one on while I am running equipment and all the equipment have either a vac with a HEPA filter on the big dust collector. But I know dust is in the air.

I found the best way to mount the air filtration unit to the floor joists is to put 4-eye bolts in the floor joist and put 4-S hooks on them. Malcolm / Kentucky USA

This makes me wonder if anyone makes a wood dust filtration system that works using a fluid?

As a teenager, my first car was a 1963 Volkswagen Beetle. The air filter was simply a contraption which included a light interior coating of oil. Water wouldn't work because of its affect on humidity and then wood moisture and also tool corrosion, but how about vegetable oil? That VW air filter certainly picked-up a lot of dust and cleaning it out was a breeze (no pun intended).

I just bought a WEN filter unit. I can't really see any difference between it and the Jet, or for that matter, any of the other ceiling mounted filter boxes. It is very reasonable at about $125 right now. Filters are cheaper and same filtration as the Jet. https://smile.amazon.com/WEN-3410-3-...478446647&sr=1

I hung it up single handed to the roof beams in my shop. About 30 lbs, I put four hooks in, perched the unit atop a ladder and hooked the chains to the hooks on top and it was done.. 3 speed, 1, 2, 4 hour auto shutoff, 1/6hp blower (same as jet), painted black crinkle finish. Filters are cheap too. No shipping cost on Prime. I'll be getting a second unit for my garage where I mill my wood. My shop is pretty small (12x24) so I think one unit will do there, but a second couldn't hurt since I too start caughing if I take my mask off . Very happy with the purchase and it is nearly 5 stars on Amazon reviews. With Amazon, if it doesn't work right, send it back with no hassle.

Seems to me you could just spray a light oil on a filter and get that effect. But without a filter medium of some sort a lot of large particles will get through. The dual filter idea is about trapping the large particles so they don't prematurely clog the small particle filter.

BTW, I'm a throat cancer survivor and I am happy to spend whatever I must to keep carcinogenic wood dust out of my throat and lungs. The lungs can't expel the really fine particles, so mask, dust collection and air filtration are not excessive. I read a couple of years ago that the EPA tests of small home shops show dangerous levels of fine dust, far more than the typical commercial shop.

All of the early automotive air filters that I remember were oil bath. I think you filled it with whatever motor oil you were using down in the deep south but up north I would imagine it had to be light weight oil for winter. I think they worked fairly well but I think one of the biggest problems was that they tended not to get serviced often enough. It seems to me that when I worked at a service station in my late teens that we would check the filter to make sure that it had enough oil in it when we were filling the tank. That kind of dates me when you say you remember when they checked under your hood while your gas was being pumped for you.

K & N air filters still use oil but you spray the oil or at least wet a filter media with filter oil and it is captures particles efficiently while allowing more air to go through the filter. I first started using them on chainsaws working as a faller or bucker in the "bush" up here.

Great reminder post, time to clean the filter in mine. No doubt the results will be the same as posted by ed.
