Over the summer I purchased a used furnace fan with the intent of building an air cleaner. Have not done it yet, but getting close. In the meantime I have the opportunity to buy an unused, second hand Delta 50-860 for $200.
I am wondering whether it makes more sense to buy the Delta rather than build my own. The filters alone on the Delta are worth $80(?).
What would you do? Does $200 for the Delta seem like a fair price?
