How much do you care about your family's health? Believe it or not, this question is directly proportional to the quantum of healthy, wholesome water you wish to provide for it. In these polluted times, simply ensuring the purity of drinkable water is not enough. You need pure water for bathing, washing clothes and utensils, etc. The number of households getting hooked to the whole house water filtration system idea appears to be on the rise. More and more people seem to be making enquiries - both online and otherwise - about the cost-effectiveness of installing water filtering units with their main incoming water supply. Depending on the size and complexity of the unit, you can now get rid of water-borne irritants like rust particles, dirt, and sediment. Not to mention VOCs or volatile organic carbon compounds, iron, sulfide particles, cysts, chloride etc.
When you go in for a heavy-duty filter, make sure that you get one of top quality with the hardware approved by NSF. Also get one with a fairly sizeable diameter inlet to enable a better flow. Also, make sure that you get filter sizes that are pretty standard, so that they can be easily replaced should the need arise. Of course, the original filter itself should be of a high quality with a long life span. It would also be in your best interest if the installation is less complicated in terms of interpreting instructions should things go a wee bit wrong. Also, do get a strong mounting bracket so that it doesn't crumble with the passage of time.
