SpectraPure Drinking Water System Cartridge Replacement Kit -FK-DWS

These folks have the best products and the very best customer service. I have been buying my water products from them for many years and can't even fathom buying from anyone else.

I've just installed new filters and a RO membrane in my DW/RO system.
Awesome shipping, great product, clear instructions!
I am a very satisfied customer

After 3 years, my tds reading went up to around 45. Historically, it would read 6 or 7.
I thought it was time to change the ro membrane and 3 filter. The change out was easy and fix’d my problem. My readings are now back to 6. I really like having the tds meter attached to the ro unit. The photo provided showing the location of each filter type was a big help.
Thx
