I want to test the quality of water coming out of our faucet + out of the fridge filter. The purpose is two-fold: to see how bad or good the water is to begin with and whether it's really that critical to replace the fridge filter as often as it is indicated.
Can you recommend any specific test kits? I found several on Amazon but not sure what to pick.
Keep in mind a filter "gets better with age". As it loads up with contaminants, it actually allows less and less to pass thru. The negative side of that is that less and less water will pass thru also and eventually the flow becomes affected. Not something I'd ever recommend for your car because the side effects are much more significant i.e. gas mileage, power etc..., but I don't change my fridge filter until the flow starts to become reduced. Usually about 8-9 months.
If you don't stand behind our troops, please feel free to stand in front of them.
