10 facts you should know about your water (before RFK Jr. ruins it)
From shopping for water filters to making distilled water, get familiar with your home (and travel) water supply

Why do you use a water filter attachment on your kitchen faucet? Why do you have a filter in your water pitcher? Is fluoride helping or hurting water? Why does out-of-state water taste so strange?

These are all questions that would’ve stumped me last year. I’ve been using a water filter for so many years I’ve lost count, but I wouldn’t have been able to give an educated answer about why I’m using it — other than saying I don’t want to drink warm tap water. Even before I got a water pitcher with a filter, I would boil huge pots of water on my stove, wait for it to cool and fill up two 32-ounce pitchers to drink from. Why? I didn’t know. I just did it.

However, after thinking about this thoroughly, I choose to continue promoting intriguing products from small businesses, women-owned businesses and (specifically) Black-owned businesses who still feature their items on Amazon. All five of my Substack publications now include a MINIMUM of one product sold by a Black-owned business. (I have visited the seller’s official site, not just the Amazon Black-owned logo, to verify this.) If you still choose to boycott, I 100% respect that decision.

It wasn’t until I wrote a post about how to clean an iron, which included instructions on how to make distilled water, that I started really paying attention to why I’m doing what I do when it comes to water. Because after all the bickering about Robert F. Kennedy Jr., the 26th Secretary of the U.S. Department of Health and Human Services (HHS), about why fluoride in water “is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders, and thyroid disease,” I need to know whether he’s going to ruin water with some of his maniacal ideas — or come up with a few I agree about.
