Frequently Asked Questions
Click a question below to reveal the answer.
How often should I replace these?
We recommend replacing both filters every 6 to 12 months. If you live in an area with poor water quality or have high usage, change them closer to the 6-month mark.
Will these fit my RO system?
If your under-sink system uses "inline" filters (filters that look like white cylinders with tubes connecting directly to them), these will likely fit. They are the standard 10-inch size used by most brands.
Do I need a plumber to install them?
No. These utilize a "Push-Fit" design. You simply push the tubing into the end of the filter to lock it in place. No special tools are required.
