We built Stasis because we got tired of the noise.
Most of what goes on in the world is out of your hands. Your home isn't, and Stasis shows you what's going on in its water, air and light.
Getting a straight answer about your home is hard.
Nobody should need a science degree to know what's in their tap water.
Your feed tells you the water is poisoned and the candles are toxic, and the next post is selling you a filter. A headline says the drinking water limits might be rolled back, and nobody explains what a rollback would mean for the tap in your kitchen.
Between conflicting studies and people selling filters, getting a straight answer starts to feel like a second job.
Nobody should need a science degree to know what's in their tap water.
So we went through the claims about the home one at a time and kept only the ones the research backs. We built Stasis around the three parts of the home that research shows can affect your health: your water, the air you breathe indoors and the light you live in.
- 99%
PFAS, the forever chemicals, turned up in the blood of about 99% of the US adults the CDC tested.
CDC / NHANES - 2 to 5×
Some pollutants are often two to five times more concentrated indoors than outdoors.
EPA - 9,300 lux
In one study an open playground measured about 9,300 lux at eye level, while rooms with windows measured a few hundred. Sitting by a window can mean getting far less daylight than you think.
Measured at eye level (PLOS ONE 2021)
You track what you do and what's going on in your body. Nobody tracks where you live.
Your watch counts your steps and calories, and your blood work shows what's happening inside your body. The home you spend most of your life in probably hasn't been tested in years, if ever.
What's in your water and air, and how much daylight you get, can affect your health for years. There just hasn't been a simple way to keep an eye on a home day to day.
If you're raising kids, you can't control what happens at school or at a friend's house. At home you can know what's in the water they drink and when to keep their bedroom window shut.

Stasis keeps watch on your home.
How the rules for your water and air were written.
- 1908Jersey City starts chlorinating its drinking water.
Jersey City was the first American city to chlorinate, and typhoid deaths fell sharply. In 1974 researchers found trihalomethanes forming in chlorinated drinking water.
- 1923Leaded gasoline goes on sale.
General Motors added lead to gasoline to stop engines knocking. Lead pipes were already carrying water into millions of homes.
- 1938A DuPont lab accidentally makes PTFE, the forever chemical behind Teflon.
Other forever chemicals followed in stain-proofing and firefighting foam. Today PFAS turn up in the blood of about 99% of the US adults the CDC tests.
- 1970Congress greatly expands the Clean Air Act.
The Safe Drinking Water Act followed in 1974. In the same decade the energy crisis pushed people to seal their homes tighter, which kept more of what's in the air indoors.
- 1997The EPA sets its first limit on fine particle pollution.
The limit followed the Six Cities study, which found that adults breathing the dirtiest air died earlier.
- 2026The EPA proposes dropping four of its six PFAS limits.
The limits were set in April 2024, and the May 2026 proposal isn't final yet. Either way, your water system's results don't tell you what's coming out of your own kitchen tap.
- NowStasis keeps watch on your home.
Stasis grades your water, air and light against the health research, not just the legal limit, and tells you what to do first.
How we grade
Most of it isn't in your head.
Some of what people put down to stress, like a scratchy throat or a groggy morning, can start in the house, and many of those causes have a fix.
- “Scratchy throat by the afternoon.”
- Could be
- Smog and fine particles drifting in from outside.
- What helps
- Stasis warns you when smog is forecast, so you can shut the windows before the smog reaches you.
- “Groggy even after a full night's sleep.”
- Could be
- Stale air in a closed bedroom.
- What helps
- Stasis tells you when the air outside is good enough to open the window.
- “Is the water in the baby's bottle actually safe?”
- Could be
- Lead from old pipes, which your water system's report doesn't measure at your tap.
- What helps
- A lab test measures lead in a sample from your own tap and shows how the result compares with health guidance.
- “Wired at midnight, dragging at seven.”
- Could be
- Bright light in the evening and too little light in the morning.
- What helps
- Stasis finds your best hour of daylight to get outside and tells you when to dim the lamps.
Stasis Home, in plain terms
What Stasis Home is, what it does every day, what it tests, and what the numbers on your screen mean.
Want to know exactly how a grade is made? Read our methodology.
- What is Stasis Home?
- Stasis Home is an app that looks after the health of your home. From your address it reads your water system's test results, the air monitors nearest you and your local daylight, grades each against published health research, and gives you a ranked plan for what to fix first. Then it keeps watch every day: it warns you when smoke, smog or pollen is forecast, tells you when the air is good enough to open the windows, finds your best hour of daylight, and updates your plan as new readings come in. A mail-in kit tests your own tap water in an accredited lab. If your readings don't call for any fixes, Stasis tells you that too and keeps watching.
- What does Stasis do day to day?
- The Today screen shows what to do this morning and before bed: when to keep the windows shut, when to open them, your best hour of daylight, and when to bring the lamps down. Alerts warn you about forecast smoke, smog or unhealthy air, and during your quiet hours they wait for the morning brief. Your plan keeps the bigger fixes in order and reminds you about upkeep, like swapping a filter. Your Record shows how your home did each week.
- What does Stasis Home test?
- Your water, your air and your light, the three with the strongest evidence behind them. For water, Stasis reads your water system's own test results, and a mail-in kit tests your tap in an accredited lab for over a hundred substances, each read against the health line and the legal limit. Members save 20% on every lab test, including mold and well water tests. Your air is read hour by hour from the real air monitors closest to you, along with smoke, smog and pollen forecasts. For light, Stasis works out your daylight from your address, season by season.
- What scores will I see?
- You'll see three numbers. The Stasis Score is a zero-to-one-hundred read of your home's water, air and light, where higher is better, shown with one of four states: Good, Fair, Poor or Not yet known. Your first score is a free estimate from public records for your address, and it says so; a tap test replaces the estimate with measured readings from your own home. Today's defense, the ring on Today, fills as you do the day's moves and starts fresh each morning. Your defense is the long view: how well your home is equipped and kept up, and what moved it, like the filter you put in.
- Where does Stasis Home work?
- Anywhere in the US. The app needs only your address to start, and the mail-in kit ships nationwide. Stasis Home launches in late 2026. In-home concierge is coming soon.
- What does Stasis Home cost?
- Your first Stasis Score is free. Membership is $14.99 a month or $99.99 a year, with a 7-day free trial, and you can cancel anytime in the App Store. Lab tests are priced separately, and members save 20%.
