Hard water leaves minerals and chlorine on your hair and skin every single shower. Purava filters them out — so hair feels softer and skin feels less tight, starting the first wash.
If your glass shower door spots up, that same hard water is landing on your hair and skin. Many people chase it with expensive products when the source is the shower itself.
Hard-water minerals coat the hair shaft and leave it dry and brittle. Many customers say they see less shedding in the drain after switching.
Chlorine and minerals can strip the skin's natural oils, leaving it dry and tight the second you step out. Filtered water feels gentler.
If your hair feels like straw and your color fades fast, hard water is a common culprit. Softer water, softer hair — often in one wash.
Purava runs your water through 15 stages — activated carbon, KDF, and mineral media that capture chlorine, rust, sediment, and hard-water minerals before they ever touch you.
Pop the cartridge after a month and you can see what you'd been showering in. Most people don't want to put it back.
Unscrew your shower head, thread Purava on in between, screw the head back. That's it — no plumber, no tools.
Layers of KDF-55, calcium sulfite, and activated coconut carbon target chlorine and hard-water minerals as water passes through.
Designed for high output — you filter the water without the weak trickle cheaper filters are known for.
Cartridges last around 2–3 months. When it's time, twist the old one out and drop a fresh one in. Two are in the box.
Kids and sensitive skin feel hard water most. One filter treats every shower for everyone in the house.

"After I got this shower filter, it made all the difference in the world. My skin is softer, and my hair has become softer also."
"No reduction in water pressure. Hard water residue is reduced which helps reduce dry skin and dry fly-away hair. Two filters in the package — happy with my purchase."
"Very nice — my sensitive skin is grateful. The water here is horrible, very hard and smells like chlorine."
"Exactly what I needed! We tested the water and it does filter out chlorine — which is the main thing I was looking for. Peace of mind that my family is using this!"
"It was easy to install and pressure is back to normal. I got extra filters with it. We have hard water and this helps remove a lot of the minerals and scale from the water."
"The price was much better than the filter we bought before, and it even comes with a replacement cartridge. My daughter needed one for her dorm because the water is terrible."

The 15-stage media (KDF, calcium sulfite, activated carbon and more) is built to reduce chlorine, rust, sediment and hard-water minerals. It's a shower filter, not a medical device — results vary by your water and hair type.
Typically every 2–3 months depending on your water. Two cartridges come in the box, so you're set for the first several months.
