My 23G RO system needs endotoxin filters replaced. Where is the best place to purchase them? One place gave me a $750 per filter price. There are 3 filters needing to be replaced in January. If anyone has models and prices it'd be helpful
Merry Christmas!

First off what kind of ultrafilters do you have in the unit? I get my 20" Fiberflo with the 222 O-ring and with the 119 O-ring from Louisiana water purification they run around $ 450.00 per filter plus shipping you can give them a call @ 504-289-1227 Hope this helps
