Frequently Asked
We recommend replacing your filter every 90 days for optimal performance. Subscribers get replacement filters automatically delivered before they expire — so you never have to think about it. Once the filter reaches the end of its lifespan it will begin to lose effectiveness, so staying on schedule keeps your water at peak filtration.
Yes — the Zen Spring Ion Shower Head is designed to fit all standard U.S. shower arms using universal ½" NPT threading, which covers 99% of American homes. No adapter, no plumber, no tools needed. Installation takes under 3 minutes with just your hands and the included plumber's tape and mini wrench.
No — in fact the opposite. We engineered our wide-face design specifically to over-deliver on pressure. Most customers report that their pressure feels better than before switching. Filtration and flow are not a trade-off with Zen Spring — you get both.
Our dual-stage KDF-55 and Calcium Sulfite filtration removes:
- Chlorine — 85% avg reduction across the full 90-day lifespan
- Chloramine — common disinfectant byproduct in municipal water
- Heavy metals — including lead, mercury, and copper
- VOCs — volatile organic compounds that turn to vapor in hot showers
- Scale & mineral buildup — from hard water
- Bacteria — inhibits bacterial growth within the filter

Yes — and we don't just ask you to take our word for it. Our filter is third-party lab tested and proven to reduce chlorine and harmful chemicals in your water. It's been independently verified to exceed NSF117 standards by 2–7x, meaning it performs significantly above the certified threshold for safe water filtration. View our full lab results here →
Most customers start noticing a difference within 1–2 weeks. The most common first signs are softer skin after showering, less dryness, and hair that feels smoother. More significant changes — like reduced breakouts, less hair shedding, and improved scalp health — typically show up within 30 days. Results vary based on your local water quality and skin type.

Yes — Zen Spring is HSA and FSA eligible, which means you can use your pre-tax health spending account dollars toward your purchase. This typically saves customers an average of 30% compared to paying out of pocket. Simply use your HSA/FSA card at checkout.
Yes — hard water is one of the most common causes of dry skin, brittle hair, and mineral buildup in your shower. Our KDF-55 and Calcium Sulfite dual-stage filtration is specifically effective at reducing mineral content and scale from hard water. If you live in a high mineral area, you may notice results even faster than average.
This is the most common misconception. Chlorine, heavy metals, and VOCs are completely invisible — you can't see, smell, or taste them at the levels found in most tap water. 95% of U.S. tested water sources have surpassed safe thresholds for at least one carcinogen, and 80% of U.S. homes have detectable chlorine and heavy metals in their tap water. Clear water is not the same as clean water.
