What your water
never told you.
The water you shower in isn't neutral. Here's everything worth knowing before you change it.
How it works
Yes. "Treated" doesn't mean clean. City water arrives with chlorine, hard-water minerals, heavy metals (lead, copper), and residue from old pipes. Your skin — your largest organ — meets all of it every shower: hot water opens your pores and lets it in. It isn't your moisturizer or your shampoo falling short. It's the water. That's why we built The Aguacero Report: see what's coming out of the tap in your ZIP code, from public data on 99+ contaminants.
Yes, every 90 days. A filter works by saturation: once it's captured enough chlorine and metals, it stops pulling its weight. Be careful with anyone promising "6 months" — in real testing those filters ran dry in under 3, and their "90% chlorine" claim only held for the first week. Ours holds its strength for all 90 days.
See the replacement filter →Third-party lab testing. Aguacero reduces more than 85% of chlorine across the full life of the filter (90 days of daily showers). For reference, NSF 177 certification asks for just 50%. We beat it by a wide margin — and hold it over time, not only on day one.
Yes, and it exists for one reason: so you're never showering unprotected. Your showerhead ships with a 3-month filter already inside; the subscription sends your next one automatically every 90 days. No reminders, no gaps. Pause or cancel anytime from your account.
It doesn't drop it — it makes the most of it. Aguacero is built to hold (and often improve) the pressure you already have. You filter your water without giving up the feel of the shower.
Under 2 minutes, no tools store required. Unscrew your old showerhead, check the filter is seated inside, wrap the included tape around the thread, and tighten with the wrench that comes in the box. If your current showerhead unscrews, Aguacero fits.
Your skin is your largest organ. And it absorbs what it touches — including the water you shower in every single day.
What else?
For now our product is the filtered showerhead — where you soak in the most water, and the hottest. A faucet filter is on the way. Subscribe to hear about it first.
Lake Vostok, buried under the Antarctic ice — the oldest, purest water on the planet, untouched for millions of years. We can't hand you Vostok. But we can pull out of your water everything that was never supposed to touch you.
Yes. And it absorbs what it touches. Showering in clean water — no chlorine, no hard-water minerals — isn't a skincare luxury. It's the foundation everything else sits on. Water first.
