Don't Panic. Filter.

My recent series on plastics worried a lot of you. I know, because you told me. The question: okay — so what do I actually do?
Here's my answer: You don't need to overhaul your entire life this week. You need to start with one thing. And if you start with one thing, start with your water.
Why water first
You drink it every day. Your kids drink it every day. It is the single largest, most repeated exposure you have real control over — far more than the occasional plastic-wrapped meal. Fix your water and you've addressed the biggest, most consistent source in your home.
This matters for children more than anyone.
A child's exposure starts earlier and accumulates longer than ours ever will. Microplastics directly disrupt testosterone production. Testosterone is the hormone that drives reproduction in both men and women, and it is being suppressed in a generation that hasn't reached reproductive age yet. Look at where plastic is densest on earth and you find the lowest birth rates ever recorded. South Korea sits at 0.72.
If you protect one person in your household, protect the youngest one. Start with the water they drink.
What I recommend
A countertop reverse osmosis filter. Specifically, the AquaTru Carafe.
Reverse osmosis is the most thorough filtration available for the home. It is the only type independently certified to reduce microplastics, and its membrane physically blocks particles far smaller than that.
I chose the AquaTru Carafe over every other RO unit for three reasons:
It stores your clean water in glass, not plastic. Most filters — including AquaTru's own larger model — collect the filtered water in a plastic tank. After everything I've written about plastic leaching into water, recommending a filter that puts your clean water back into plastic would make no sense. The Carafe uses glass.
It is certified by IAPMO to NSF/ANSI Standards 42, 53, 58, and 401 — the full set that matters, including the microplastics standard. It removes lead, arsenic, fluoride, PFAS, and dozens of other contaminants.
It requires no plumbing. It sits on your counter.
A note on transparency: I earn a small commission if you buy through my link below, at no extra cost to you. I recommended this exact filter long before any commission was involved. The recommendation came first. The link came second. I have this on my own counter.
One caveat about RO: Water waste
Reverse osmosis wastes water. It's how the technology flushes out the contaminants it rejects. The Carafe sends roughly a third of what you put in down the drain.
That is exactly why I do not recommend whole-house RO. Filtering every drop in your home that way wastes an enormous amount of water for no added health benefit. A countertop unit filters only what you drink, so the waste stays small.
And here in Raleigh, we are now under Stage 1 water restrictions in a severe drought. So keep the wastewater, it is just concentrated tap water. Pour it on your plants, your garden, and your lawn. Hand-watering with a nozzle is still allowed at this time. Nothing has to go down the drain.

Just make one change: Filtering your water is the highest-leverage thing you can do this month. It protects the people in your house with the most years of exposure ahead of them.
There will be more coming: food storage, air, mattress covers, etc. But none of it matters as much as the water you and your children drink every day. So start there.
