To figure out if it’s worth installing a shower filter in your showerhead, you should do a little research on the water in your area, as different locations will have water of varying qualities and contaminants. If, for instance, you live in a hard water area, it’s absolutely worth your while to install a shower filter, as it will remove all the nasty pollutants hitching a ride in your H2O, contaminants that will otherwise reach your hair and skin as you wash. In fact, even if you live in a soft water area, it’s probably worth installing a shower filter, as main water supplies in houses are almost never entirely clean. There are tons of tiny contaminants in water, and a filtration system will help clean it up before it reaches you. You can also observe your showerhead and ahower area to assess if it’s time to install a shower filter, Should you see build ups of grime and debris, and possibly even discoloration of the walls, a shower filter will bring all that to a stop. Granted, you’ll have to keep on top of filter cleaning and replacements to get the most out of your shower filtration system, but it beats having to deep clean the whole shower every month due to the build up of particulate matter ferrying a ride through your water network.
