I’m really happy that I made this choice after looking into purifying and distilling my water, I looked into electric ones and natural steam ones and found that both would cost a lot of time and energy waste by needing to purifying the water up to 4hrs at a time. I learned that the materials used in both options was of poor quality!

We were looking for a solid filter that would be easy to maintain, easy to build, long lasting, and effective. Meets the mark on all accounts!

Bought one from Amazon and I must say I had the other well named one from another company and Phoenix is better, the other company is terribly bad at customer services and rude and don’t care if you have a problem like when I ordered things that didn’t come and they literally said I was wrong and I got my things but I didn’t and called me a thief….very rude and unprofessional.
