I was thinking about getting an air filtration unit for my shop, but wanted to know if they make a big difference and are really worth it. It is impossible for me to keep my shop clean right now. I would have to dust like twice a day. It’s not only from my woodworking dust, we live on a gravel road so I get that dust too. So, for those of you that have one, did it really cut down on the dust in your shop?

Does it do any good?

I’d have to say it made a world of difference.
I built my own with a high volume squirrel cage out of a squirrel cage from a roof top RV air conditioner. I built a box around it and use 2 20X25 MERV 13 filters on the intake ends. The exit is out the top.

I have it on a pedestal by the wall about 8’ from my work table and using the belt sander without a vacuum collection the system collects about 90% of the dust. Very little dust is left on the table and none anywhere else in the shop.

I’ve been changing the filters about once a month when I use the shop 3-6 hours a day.

I can always tell, on walking into my shop, whether or not I remembered to turn on the air filter before leaving the last time. If you’ve got the space and have the need, get one.

And I need to start changing my filters more often, too…

I think this is the newer version of the one I have:

http://jdstools.com/air-tech-hp-air-cleaner.aspx

What I like best about it is the remote with the ability to set low-med-high speeds and have a shutoff delay of 1 to 4 hours. You can also do this with buttons on the unit itself, which is useful because my remote batteries died surprisingly fast.

It’s made a huge difference in my shop. I get much less of the fine dust on my machines when I use it at the end of the day. Periodically, I blow out my shop with the shop vac blower, and when I’m done I just set the air filtration unit to run for a few hours. Well worth it in my opinion.

I have the Jet AFS-1000 and like it a lot…

imo you need the thick fabric sock type filter to get the fine stuff….

the hot air furnace type pre-filters won’t cut it by themselves…. even if stacked several deep.

I turn mine on pretty much every time I run a power tool and for sure, every time I run my DC.

My shop is 23’x21’ and the filter turns over the entire air volume of the shop very quickly…..

Just the other day I was hand routing and couldn’t really catch the dust at all….. So I ran the filter on high and the shop air was cleaned up in no time.

Grizzly makes a knock off of the Jet for quite a bit less money.

Make your own.
I made mine, it makes a huge difference.
It is easy and relatively inexpensive to build.

i have a jet afs-1000 also and love it.i hung it over my workbench and it cuts down on alot of dust.you can tell it cuts the dust fog out of the air real quick(sometimes i forget to turn it on).
another thing to help cut down on dust is a down draft sanding table/box make a huge differance also.

Every dust collection/capture/filtration tool is worth it. Breathing is too important.

Now to remember to turn them on, change filters etc.

I use 2 (doubled up) 20×20 filters on my home made unit – a furnace fan inside of a box that I built. I find that if I cover the outside filter with bounty paper towels the paper towels pick up the finest dust. When they start to discolor, its time for new towels on the filter. When the outside filter will start to discolor I will put the new filter on the inside of the stack and use the old inside filter on the outside – the paper towel side. I’ve been using the original filters for over 2 years. I was thinking about putting a timer on the unit but find that if I turn it on when I first start working there is little or no dust in the air by the time I finish cleaning up what I was doing.

Glen That’s a cool idea using the paper towels. I might give that a try.

while you’re waiting, if you can source a 20” box fan cheaply enough, you can do this as a semi permenant or temporary solution:

i got luckily fell into some 1” drywall jchannel . vinyl siding j channel will work equally well. cheap, fast and easy.

i used the 1 hr timer as i had it lying around. this would be a better option, adn i’ll change at some point:
