The wording makes it sound like you only tested your filtered water. Seems like you'd want to test both the pre-filtered and post-filtered water to really know if your filters are "very effective."
- oil25 7y agoI agree, but the test was pretty expensive (about $400) so I only opted to test the "filtered" output since that's what I end up drinking and cooking with. I would definitely like to do a comparison test in the future.
- skuhn 7y agoTesting your unfiltered water as a control to your filter is a good idea, but also you're still bathing in that water. $400 seems quite high. There are much cheaper tests available, such as the National Testing Labs City Check test ($126 + return shipping) at https://www.purewaterproducts.com/watercheck/ https://www.purewaterproducts.com/watercheck/
