Easy install with great tasting results

Other than the usual 'splash' of carbon dust from the new filter, it has performed very well with great taste removal properties. The unit exactly replaced the old one which had been in 16 years (we have very clean water and this is the first I have touched it in 16 years). The filters shipped quickly and at a good price.

Tight fit

They fit my systems and everything works as it should. But it's slightly larger than expected. Though since everything else is perfect I have no complaints.


Just like I remember!

I remember when we didn't need to filter our home water. We just drank it straight from the tap. But, I get it, times have changed, and so must our habits. There are so many pollutants and unhealthy particles in our water it kind of scares me to think about it. So, anyway, a few months ago my Son helped me install a Reverse Osmosis System in the kitchen, so I can drink from the faucet again (just like old times!) The System is great, but it's a bit annoying to buy a new filter every few months. So I decided to start buying them bulk. The 25 filter bundle should hold me over for well over a year. I just want to say thank you for making this crazy, polluted world a little more like how it used to be. Thanks :)
