The science of shower water — RAINLY
Your shower should leave you feeling clean — not dry, tight or stripped.
What’s in your water?
Tap water can contain more than you think.
Chlorine
Commonly used to disinfect water.
Sediment
Tiny particles can travel through pipes and plumbing.
Heavy metals
Trace metals may be present depending on local water and plumbing.
U.S. tap water is regulated and treated. What reaches your shower head varies by location, supply and plumbing.

Unfiltered Shower
- No built-in filtration
- Chlorine and sediment remain untreated
- Water quality depends entirely on the local supply
Rainly

Inside the filter
Engineered for cleaner, better water.
First stage
Captures larger particles and sediment.
Filtration media
Multi-stage media targets chlorine and impurities.
Final stage
Final filtration before the water reaches your shower.
Performance depends on your incoming water quality, temperature, flow rate and filter age. RAINLY is a point-of-use shower filter, not a whole-home treatment system or a medical device.
