What's actually in your shower water?
Nearly all US municipal tap water carries chlorine or chloramine by design — it is how water is kept safe on the way to your home. It does its job in the pipes. Then it lands on your skin, twice a day, for as long as you live there.

Your routine starts before the products do
Most US tap water is treated with chlorine before it reaches you. Chlorine is a known skin irritant — it strips the oils that keep skin comfortable and hair manageable. So every morning, you rinse in it, then spend money undoing what it did. PRIMA reduces chlorine before the water leaves your showerhead. Nothing else about your routine has to change.

What changed for them
"I stopped needing conditioner every single day. My hair used to feel like straw after every shower — three weeks in and that's just gone."
"Honestly bought this expecting to return it. The water smells completely different — no more chlorine smell hitting me when I turn it on."
"Took me maybe 40 seconds to install and I am not handy at all. Screwed it on between the arm and my showerhead, done."
"My daughter's eczema flares have calmed way down since we put this in the kids' bathroom. That alone was worth it."
"Pressure is exactly the same, which was my main worry. Only reason it's 4 stars is I wish the cartridge lasted longer than 60 days."
"We're on well water and the buildup on the glass door was constant. Way less scrubbing now. Ordered the 3-pack so I always have a spare."
Try it for 30 days
