818, DI Resin Refill Bag 16oz (good for up to three refills)
[818]

I've been a customer for years and have urged several people to purchase RODI units and replacement filters and parts for quite some time now.

I just wanted to thank you for the clear, precise order of all I purchase and the quickness of getting orders out. I was amazed and grateful that I actually received this order in only two days.

Sincerely,
michael lanphier
