LiquaGen KDF 55 Copper Zinc Filter Media – 1 lb Recyclable Granules for Chlorine, Iron, Heavy Metals & Bacteria Removal – Extends Carbon Filter Life for Whole House & Drinking Water Systems

This stuff works great. I use a pound of it in a filter that contains bone char carbon. This media protects the bone char carbon from getting consumed by chlorine in my municipal water. I have a standard carbon block filters after that filter.

Good product, as advertised!

Built a prototype water filter for the homestead, and it seems to be working great. I added the kdf55 media to improve filtration, and it's proven to be a good addition. 1 lb of kdf55 into 2lbs activated carbon, then 1 lb of fine sand. All contained in 14" of 2" pvc, super simple. Water comes out sparkling clear and tastes great.

I spent about a year installing high end water purification products, and kdf55 was one of the products we used on a regular basis when we wanted to go beyond standard charcoal filtration and add in some antibacterial media to a system. Just as a refresher I checked again for research indicating that there were no negative health effects associated with this product, and I was unable to find any issues associated with it. Like the title says, this stuff is what the pros use, and the price is pretty close to what a water treatment guy would pay wholesale. absolutely no complaints there.

Didn't do anything...
