I have a 63" Mimaki & I bought the Island Clean Air Duster for around the 5K pricetag Barry warned you about (minus all the discounts Advantage gave me on my printer/cutter/laminator/scrubber deal)
I forgot to turn it on a few times that first week & that is the only reason I even know that my inks smell (& eventually my eyes feel irritated too) Now that I have my routines more familiar, I never smell any fumes. The duster is rated for a 2000 sq. ft. room. I have only 750, so often I don't turn the dial up to full blast (it makes a noise like a fan.. not a big deal, but something to be aware of.
You can run duct work ut the roof & put a fan up there to pull out the fumes, but then if you rearrange the shop or move to a new location, you will incur ventilation expenses again. so I went with the duster knowing I would then be set for venting no matter what the future holds.
