Happy with this water filtering system
This is the third year I use this water filtering system and I am very happy with it. The original installation was challenging and I recurred to a handyman to help, but since then replacing the filters has been easy. I will continue using this system.

Love the triple filtration system
I have been using the Crystal Quest undersink triple filtration system for ~20 years and LOVE it. It makes the best tasting water, but also removes dangerous contaminants for much less cost than reverse osmosis. And we only have to replace the cartridges ~ every 3 years.

Coconur Carbon Filter
so far good - time will tell
