When all else fails, check with this group. Reading past comments, the JDS Air -Tech 750 ER seemed to be one of the better ambient air cleaners used by members. Where can you get a price/buy one?? None of my normal sources seem to carry them....or is there a better system (cost effective) out there? Thanks for the help and input.
I went to the JDS website and it appears that they no longer make the cleaner. They are still stocking replacement filters for it. As for alternatives, there are several good ones. I don't have a recommendation for you.
Buy a box fan or pick one up at a yard sale, Goodwill, etc.
Go to Amazon and look for a MERV RATED Electrostatic Washable Permanent Furnace A/C Air Filter. Prices range from the $20-40's. I bought one at a box store years ago with a .3 micron rating for under $30.
Tape the filter to fan's frame on the inlet side. You could even put a cheap 99 cent filter on the fan exhaust side just taped (held in place) on the top to direct the air down.
I use one at my lathe instead of my dust collector. Three speeds, much quieter, and VERY effective.
