I Love It

I love this system! Not only is it healthy for me but helps the eco system by not having to purchase water bottles! I have already told all my friends and family to make the switch!

Wow, How Times Have Changed!

As someone who used to work in the R&D section of an RO system manafacturer (this was years ago), I'm so happy to see the leaps and innovations made in this field. Back then, you called a plumber to install the system. And if you were a plumber yourself, you'd still call another because the process was so unintuitive and slow. Now it's so simple! Installation was so easy. I just hooked it up under the sink, did a few pre-use washes, and I was done. And, more importantly, the water coming out the other end is pristine. These new guys are putting me to shame!

Under Sink Water Filtration System

We are a family of four, this is all we use when we need to use water for consumption. Our water without the system always smells of chemicals (chlorine) and we just can't stomache drinking it.. We don't like using the water in rooms other than the kitchen to brush our teeth or even take a shower as the smell and taste of the water without the system can be unbearable. We recently have purchased a shower head filtration system to help in the bathroom while taking showers. We feel confident that the water is clean and free of chemicals with this system. We have only had to tighten one of the filter casings once as it started to leak over time. We have had it about 6 months now and may have to change some of the filters , but the water flow is still substantial and it continues to work as intended.
