Filter for air conditioning in shop

I am not going through another summer without an air conditioner in the shop. It’s not just for the coolness but also to cut down on the humidity.

I am hoping someone here can suggest a solution to the filter to keep all the sawdust out of it.

I have a dust collector which I am going to “box in” to one corner of the shop with some kind of filter for the air coming out of the “box” due to all the air being sucked in.

Second I have a dust filter/air cleaner hanging from the ceiling, so with that and the AC on I assume that each will collect half the sawdust floating around.

I don’t want to get a real expensive filter because I will be replacing them all the time. Maybe a bunch of cheap ones?

What I’d really like to do is buy a great washable one that I can keep on using forever.

Any suggestions?

Hello Gary
whenI lived in Memphis, I bought a small cheap used window airconditioner. I didn’t worry about any additional filters other then the foam filter that came with it. It worked fine for three seasons. Just washed the foam when I thought about it. Airconditioner eventually got pretty dirty looking, so I washed it out with the garden hose. When we moved, I gave it away to a friend. They still use.
Regards
DAN

Just an idea here, I use the J. M. insulation around my filter of my large vacumn . I am using this system to pick up dry wall dust. I also leave the vacumn on with the suction tube below the sanding area. The vacumn does not loose any suction for a long time when insulation is used as a prefilter. When it does lose some of it’s suction, I remove the insulation from the filter, and it is not even dirty yet. JUST THROWING this out to start your creative juices flowing. note: without 1 1/2 in layer of the prefilter rubberbanded to the filter, the vacumn looses suction within a few minutes. all the drywall is in the filter, and is imposibal to clean.

Hay Gary,
I use the green fiber filter, that you can buy at Wal-Mart and cut to fit for my hot air furnace. Works great, and as needed, I simply remove it and blow it out with the air compressor or you can simply wash it. You could cut it to size and use Velcro to attach it over the return air side for easy removal. One can never get rid of all the dust, but this does a fair job cutting it down. I also use a box fan with a filter attached setting beside my sanding operations to help collect a lot of the dust before it can get air borne.
Hope this helps you.
God bless

olddutchman – I thought of using insulation a while back but forgot about it. I will look into it.

Gene – That green filter media sounds interesting. I will have to go ckeck it out. Thanks

Has anyone ever used an electrostatic filter?

Gene – I couldn’t find any green filter media at Walmart. What department is it in?

Thanks,
Gary

My air filtration system hangs from the ceiling.

I have three filters that I rotate. When one gets full of dust I replace it with another and then take that dirty filter outside and blow it clean with the air compressor.

I like the pre-filter idea.

Gary, I have a Delta air filter. I retro’d it with an electrostatic filter and it works real nice. Just take it out an wash it. Penn State Industries carries them. Also, on the air conditioner track, when I’m making dust and the a/c is on, I usually just make sure the filter is running also. I just have the foam filter that came with the a/c. Doesn’t get dirty extra fast and I haven’t had any trouble with it. I may look around for an electrostatic filter for it also.

the only solution i know is to reduce the actual dust. any filter will require cleaning.. the less dust the less cleaning.
