Buying a water filter is important if you have hard water in your home. But to be sure whether the filter you buy will do the job or not, you need to have a proper idea about the level of hardness and the contaminants that are in the water. You need to test it first with a water testing kit like Watersafe and First Alert. These kits come with mechanism that can not only test the hardness but also the different contaminant that are present.
Take An Informed Decision:
Different filters are good for different purposes. For moderate to low levels of impurities, installing a salt free filter is the way to go. For high levels of chemical impurities, salt based filters are the best. If the impurities are both organic and inorganic then RO filters should be opted.
Although a lab test is always better to examine the water properly, the home test kits are now quite improved and will often provide you the same results at the fraction of a cost. Visit http://www.softwaterfiltration.com/ for more information and install the best filtration system for your home.
