Would have rated higher but annoyed by the excessive ad emails - every day, or every other day, or every 3 days, seemingly for ever. If it doesn't stop I'll tag it as spam.
Filter came in a timely manner and in great condition. Works well so far, would definitely recommend to others and intend on using filterbuy again in the future.
As I review my problems in my earlier emails on the failure of the unit. The unit had a poorly construction design and the side walls failed while entering the unit in furnace. The side of container unit hung up and by adding more pressure the side walls imploded in and the unit was hung up. It destroyed the unit in trying to remove it from the furnace. Sorry the unit look good, I tried to explain the root cause of failure in my earlier emails. I hope my analysis of the problem can help.
