It depends on when you placed your order. The filter has been sold for at least three different prices: the crowdfunding price, the post-crowdfunding preorder price*, and now at full price.
* There may have actually been two different post-crowdfunding preorder pricing structures, but I can’t remember for sure at this point. I seem to remember a price increase at some point in there but I’m not sure.
You call that a hole? When the Parthenon in Madison, WI decided it wanted to go from a quality gyro place to a blue and white McDonald’s, they dropped the entire building into the foundation. On the plywood-wall keeping pedestrians from falling off the sidewalk and into the rubble filled gaping maw was a sign that said, “Closed for Remodeling.”
Quality gyro place = you must be afraid you’ll catch a communicable disease.
LOL, I contemplated the same thing, but “she who must be obeyed” vetoed it instantly. I am using a window vent instead, which has worked out OK. I contacted GF support and they refunded me for the filter.
