I buy it from local HVAC wholesale stores. United Refrigeration is normaly the one I use & they are nation wide. As Dave mentioned I'd think the Home Improvement stors would carry it.
It can be rolled to fit in a bucket. When used as an air filter it has to have a frame to support it since it's very pliable.
I would think cutting large holes in the bottom of the bucket would be best & letting the water filter all the way down through the media.
Bruce, I just checked prices, all they had in stock was 25" wide X 90ft long roll for $60.00. I would think that's more than you need but if you can't find any I'd be glad to pick some up & ship it to you. I Should be able to order a shorter roll.
