OnliPure Edition Ion-Exchange Post Filter

Easy to replace once you actually read the instructions

If you don’t have very good strength in your fingers, this won’t work for you. I’ve had the unit for a year now. It’s still very difficult to disconnect the old filter. It takes finesse and super strength! The quality of the water is still excellent, however….once you finally get the filter installed!

I get a lot of use out of this filter. Couldn't install an under-the-sink RO unit at my apartment, but the OnliPure filter is well worth the cash and counterspace. Bought a TDS tester out of curiosity, and its reads 0ppm when I tested water from it.

Ordered replacement filters today for my counter top unit. Barbara at RKIN made ordering fast and easy. Her knowledge of my unit and the filters I needed was helpful and she had answers to all my questions. Outstanding customer service.

0 TDS is real with this post filter. Barbara provides incredible outstanding service, on the phone, via email literally minutes after you sent her an email.
