What our customer's say!

"A great idea, but problems.", I've had two of these.
When they're working they're great. Unfortunately the plastic mounting rings break occasionally and sometimes the filter gasket leaks.

"It does the job.", I have an undersink filter that came with my house. Changing the filter always meant finding someone to do it for me,since it meant turning off the water and a lot of effort. And always a mess!

This is a simple solution that I can change with zero effort and requires no outside help. A turn in one direction and the filter is off. A turn in the other direction and the new filter is on.

Drawbacks: They need changing very frequently. The cost mounts up. The water doesn't come out with gusto, but not a trickle either. Just less force.

I like the additional settings which bypass the filter, saving on filter usage.

It could be better, but it isn't bad and a whole lot easier than the under the counter type filter.

It is reasonably attractive for what it is.

"Faulty R-8 Replacement Filter", I purchased one of these as a spare. Upon recently installing it the green light - to indicate it's useful life - was not working. I ignored this. Then, 30 days into it's use it's water output suddenly reduced to about 10% of normal. This performance was entirely different from the original cartridge that came with my original filter unit purchase.

I feel I've been had by WaterPik.
