Letter Re: Doulton Water Filter

I have made a very similar PVC tube filter as in the article. It holds 1/2 gallon at a time. I have an RV filter on the faucet to pre-filter the water. A lot of homemade water filters like this have it sit on top of a 5 gallon food-safe bucket with a spigot towards the bottom. I prefer the one gallon glass jar. – R.V.
