your tap water is hiding something scary 🫣

🎥 Rachel Cuello

NYC tap water after 10 days 🤮 It’s not the water, it’s the pipes.

The scariest thing in a NYC apartment isn’t the rent 🫣

This mom couldn’t believe she was washing her face with this the whole time 😳

She always had a feeling her building’s water wasn’t clean. Then a neighbor posted her filter in the building group chat… and one month later, this is what came out of her own tap.

No matter how nice your home is, it’s the pipes that make your water dirty.

The Puresoft Filter catches the dirt, rust and sediment before it reaches your face, and food-grade vitamin C neutralizes chlorine. Installs in seconds, no plumber needed ✨

What would you do with one wish?

We installed the Puresoft Filter at Princeton University 🧡

Her dorm is over fifty years. We unscrewed the aerator on her sink and found dirt, rust, and microplastics, all from her water pipes.

But this isn’t just Princeton. It might be your sink too. We’ve visited over 100 homes and found the same gunk everywhere, because the average US water pipe is 45 years old.

The Puresoft Filter:
✅ Catches impurities 50x smaller than a grain of sand
✅ Neutralizes chlorine and chloramine with 99.5% pure food grade Vitamin C
✅ Fits any faucet
✅ Made in Korea

You can’t fix the pipes. But you can filter your water.

NYC tap water is famous for being some of the cleanest in the country. Then it travels through pipes that are 80+ years old. Those pipes break more than once a day, stirring up sediment that ends up at your faucet.

This customer’s cartridge went brown in a week 😳 That’s faster than most. The cartridge is built to last 4 to 6 weeks, and hers pulled a week’s worth of sediment straight out of her building’s pipes.

But this is bigger than New York. It’s a nationwide issue affecting millions of Americans every day. Large historic cities like LA, Chicago and Boston are still running water pipes way past their due date. Chicago has pipes over a century old. Boston has some laid in the 1800s. Nearly 1 in 5 water pipes in the US is past its useful life.

US water infrastructure got a C- from ASCE in 2021, then a C- again in 2025. Nothing changed. We put $50 billion into fixing it. The EPA says we actually need $625 billion over 20 years.

That math doesn’t close anytime soon, and we’re nowhere near fixing the pipes. What we can do is filter the water we use to wash our face, brush our teeth and rinse our food every day.
