Topic tags/keywords: question

I would like to hear from those of you that have an air filtration unit set up in your small shop. My “shop” is actually a one car garage approximately 12×20 x 8 feet high. I have the Harbor Freight 2 hp dust collector w/Wynn nano filter cannister.

I hope to order a filtration unit in the near future. Being able to replace the filters with those from the big box stores would make it really nice. Is there such an animal?

Note: Currently I am using a 20×20 box fan with a filter taped over the suction! Believe it or not, it does work.

Your thoughts appreciated.
Thanks in advance.

MT, I have the same DC setup as you. For air filtration I built a box around a HVAC blower. I used this filter from Grizzly between the the blower and a washable pre-filter.

I too am using the box fan and filter econo-dust system until I can reign in my tool buying habits. Current space is 10×12. Looking forward to some ingenious DIY (cheap!) filtration system ideas here. Attached overhead/movable shrouds would be interesting.

Furnace filters catch an amazing amount of airborne dust. I use 3 furnace filters on mine. I’m sure if I were to use the better 3M Filtrete filters, they would work better.

I want to buy one that uses readily available filters.
