Arsenic water system filter
I already had a junky filter installed along with a faucet, so t was very easy to pop in the Crystal Quest filter system. Water tastes great now

Thank you so much for your feedback, it is greatly appreciated.

Need a better instruction manual.
This is the second under sink 3 filter system for arsenic removal I’ve purchased. This one is for a rental house. The first I’ve had for a year in my own home. It’s very nice material quality and greatly improves my water taste and quality. I would strongly advise Crystal Quest to improve the installation guide. The writing is very small and overall very poorly illustrated and written. A high quality installation guide would really improve initial purchase satisfaction.
