The phrases replacement water filters and shower water filters may rhyme with each other but they are completely different in terms of context and content. There is some correlation but replacement filters are not really products like some people think. Any type of water purifier has a filter inside it. The job of the filter is to remove the contaminants present in the water and purify it. While the purifier does this job 24 hours of the day it becomes choked and clogged. At the end of its shelf life is when you need to replace the filter. A water purifier attached to the showers has a specific purpose that many find very useful.
In almost any water purifier the contaminant molecules are either attached to the filter medium or they get stopped from passing through the medium. At the same time the water molecules are allowed to pass through. Now while there is this continuous deposit of contaminant molecules on the filter it can still continue to function for at least a couple of years. However, you need to clean it from time to time so that it becomes clog-free and continues to perform its job. But after a couple of years you need replacement water filters because now the existing filter, no matter how much you clean it and all, will cease to perform.
You should have a water test kit at home that can indicate the purity level of the filtered water. When you find that the purity level has dropped and the flow of water through the filter has also gone down you need to clean the filter. The results will pick up immediately. But continuous wear and tear will ultimately require replacement water filters and you should never neglect this time for change. With kids at home you can never take a chance with the water quality.
Some people also need shower water filters. These are filters that are specifically used on shower nozzles. These filters fit in like caps on the shower nozzles and their job is to purify the bathing water before someone bathes with the water. Most people don't need these filters because the water that is supplied at home is cleaned commercially and is generally within the EPA standards.
However, there are specific locations and specific people that need these filters. There are places in the US where the water quality is not the greatest in the world. And there are people that suffer from skin allergies caused due to impure water. For you and me the water quality could be alright but with those with sensitive skin it could be really bad. Shower water filters are perfect for such people.
You should never take a chance with water filters when you have got used to using them. If you have been using water filter for purifying your drinking water then replacement water filters should be bought at the right time. If you have sensitive skin shower water filters should be used at all cost.
Both replacement water filters and shower water filters are important to consider when you are in the habit of using water purifiers. Online shopping for these products is easy and convenient.
