KDF Media vs Silver Impregnated Carbon – which is better in a whole house water filter?
It’s my opinion that bathing in shower water when there is a silver impregnated carbon whole house water filter on the house can harm your skin’s micro-biome. Why? Because silver kills bacteria. It is also a well known fact that the silver leaches into the water supply and needs to be replaced often. KDF Media vs Silver Impregnated Carbon – Which is Better in a Whole House Water Filter?
I use KDF in my Urban Defender whole house water filter. While KDF can be used to turn chlorine into chloride, as it does in shower filters, I use it in the Urban Defender for
- its anti-bacterial properties,
- its ability to remove certain metals from water such as lead, and
- its .01 millivolt electrical ionization.
A comparison shows that KDF is the better choice.
Here’s a chart that shows the difference between the two.
KDF Process Media vs. Silver-Impregnated Carbon
|Life||More than 6 years*||Only 6 to 12 months|
|Bacteria and Algae||Controls Both||Permits Growth|
|pH||6.5 to 8.5||Sensitive|
|Use||POU/POE, Industrial, Commercial||Home Water Filter Products|
|US EPA Registration||Not Required||Required|
While silver impregnated carbon is known to leach silver into household water, what about KDF? A brief internal study shows that there is no obvious leaching of either copper or zinc into household water.
