Can Berkey Filter Snow?

Yes. However, make sure to follow these recommendations: 

1. Don’t put ice or snow directly into the upper chamber. Allow it to melt first. The Black Berkey Filters can become damaged and quit working if frozen.

2. Boil first, if possible. Berkeys can filter out at least 99% of over 200 pollutants. However, we don't know what’s in your ice or snow, and neither do you. If possible, boil the water first, and allow it to cool, before putting it into your Berkey filter unit.

Berkeys are made for disasters.

Berkey Filters don’t require power, running tap water, frequent filter changes or refrigeration. They’re durable and long-lasting. You might say Berkey filters were made for disasters. They have the incredible ability to filter over 200 pollutants, ranging from the chlorine in municipal tap water, to microorganisms and bacteria found in lakes, streams, and rivers.

However, without definitively knowing what's in your snow or ice, we cannot be sure that Berkey will filter it out completely. For this reason, we recommend that you boil the snow or ice first, and allow the water to cool before pouring it into your Berkey.

If you can't boil the it, we recommend mixing a small amount of chlorine in the melted snow/ice water. Chlorine is proven effective in killing harmful bacteria. Chlorine has its uses, but we don't want to be drinking bleach. Luckily, you can treat your rain/snow/river water with chlorine and then remove the chlorine (and its byproducts) with your Berkey! Berkey successfully removes over 99% of chlorine from your drinking water.
