Can Filter150 weighs 150 pounds!!I put all my fans inside a sealed box lined with foam and egg cartons.
If you don't mind me asking, what size filter weighs 150 lbs?
I use an Organic Air carbon filter [12"]. This thing looks like a huge K&N automotive air filter, weighs 20 lbs, is re-useable, rated at 4000cfm, and costs approx $200.00.
When I researched carbon filters, the standard ones seemed to be overly restrictive, non reuseable, and expensive.
Hope this helps. bg
