Claims
- 1. A fluid filter arrangement particularly useful in removing selected impurities in drinking water including a hollow casing means, removable top end, and bottom end, defining a chamber and having an inlet in said top end for admission of water to be treated and an outlet in said bottom end for emission of treated water, replaceable treating material retention means to be located within said casing means and having a sidewall of generally the same shape as the inner wall of said casing means so that the sidewall of said replaceable material retention means engages the sidewall of said casing means in sealing relation and where said replaceable material retention means includes a concave water porous, inlet end to be disposed in communicative relation with the water inlet and water porous outlet opposite said inlet end communicating with said water outlet from said casing means and selected absorbent material retained within said replaceable treating material means is replaced by terminating the flow of water to said hollow casing means and removing said top end of said casing means.
- 2. The invention of claim 1 wherein said inlet end is of generally hemispherical configuration.
- 3. The invention of claim 1 wherein said inlet end is of generally conical configuration.
- 4. The invention of claim 1 including sealing means surrounding a portion of the periphery of said treating material retention means to prevent leakage of water between the inside of the casing and the treating material retention means.
