Are water filters worthwhile?

So, that 4392857 filter in your fridge needs to be replaced and you’re wondering if it’s worth the money. There are so many other things you could be spending your money on (like paying those never-ending household bills or putting gas in in your car!) There are so many contaminants out there, though, that could be in your water, it’s hard to say no to a new filter. Lead, mercury, chlorine, benzene, cysts, spores, and so on: depending on where you live and whether you have public or private water, you don’t know which of these your water might have unless you get it tested. It’s always worth being safe instead of sorry.
