Selvanto Bowel Relief Capsules
MiraLAX every morning for four years and I was still only going once a week. First week on Selvanto, I went every morning without cramping. I stopped the MiraLAX by week six. I'm 53 and I finally feel like my body works again.

How do I install the Selvanto detector?
How do I install the Selvanto detector?
Plug it into any outlet in your RV and give the sensor 200 seconds to calibrate. That's it. No drilling, no wiring, no complicated setup.
CO mixes evenly with the surrounding air, so almost any outlet works — sleeping area, kitchen, dinette. Plug it in and you're covered on the road.
How many detectors do I need?
How many detectors do I need?
One detector in an RV is better than none. But in a small space with a stove, a furnace, and a water heater, one isn't enough. Put one near the sleeping area and one near the propane appliances. At minimum, two.
And the risk doesn't stay at the campsite. Your home has a furnace, a kitchen, maybe a garage. That's why multi-packs exist — cover the RV and the house in one order.
What do the displays mean?
What do the displays mean?
PPM: The concentration of carbon monoxide in your air. Zero means clean air. The higher the number, the more CO is present. Selvanto alerts you before 30 PPM — long before standard detectors are required to make a sound.
GAS LEL: The percentage of natural gas or propane in your air. Zero means no leaks. Anything above zero means gas is escaping somewhere. Act immediately.
Humidity: The moisture level in your air, shown as a percentage. Normal range is 30% to 50%. Helps you maintain comfortable, healthy air inside the RV.
Three values. One screen. No guessing.
How is this different from a standard detector?
How is this different from a standard detector?
Standard detectors show a green light. Selvanto shows live numbers.
Standard detectors are allowed to stay silent until 70 PPM. Selvanto alerts before 30 PPM.
Standard detectors only sense carbon monoxide. Selvanto detects CO, natural gas, and propane.
Standard detectors use basic level 1 sensors. Selvanto uses level 3 sensors — faster, more accurate, longer lasting.
Standard detectors leave you hoping. Selvanto lets you see.
As Seen On
You checked everything. The detector is quiet. So why don't you feel sure?
Because you're right not to.
The detector on your wall is built to a standard that requires it to stay completely silent below 70 PPM — and even after reaching 70, it can wait up to four hours before making a sound. In a space as small as your RV, with your family asleep, it has no obligation to tell you anything until the air is already dangerous.
It's not broken. It's built that way.
Selvanto alerts before 30 PPM. Live numbers on a screen — not silence. CO, propane, and natural gas — not just one. The quiet you've been trusting was never designed to mean safe. Now you can actually see.
You can't see it
No color. No haze. Nothing visible at any concentration. Your eyes are useless against it.
You can't smell it
No odor at any level. The first thing most people notice isn't a smell. It's a headache they can't explain.
You can't feel it building
It rises while everyone sleeps. Your detector can stay silent through all of it until the air is already dangerous.
If you sleep near anything that burns fuel, this applies to you.
An earlier alert means you're still awake when it matters.
Most RV owners assume they're covered. But a smoke detector only detects smoke — not carbon monoxide. A standard CO detector only detects CO — not propane, not natural gas. And most are built to stay silent until levels are already dangerous. That leaves gaps. Selvanto closes all of them in one device.
⚠ What ordinary detectors miss
- ✕ Smoke detectors are blind to carbon monoxide
- ✕ Most CO detectors don't pick up natural gas or propane
- ✕ Standard units can stay silent until 70 PPM — and wait hours after that
- ✕ No protection against gas leaks from your stove, furnace, or water heater
✦ What Selvanto does differently
- ✔ Detects CO, natural gas, and propane — three gases, one device
- ✔ Alerts before 30 PPM — long before standard detectors are required to sound
- ✔ Displays live PPM on screen so you see what's happening, not just silence
- ✔ Plug-in power — no battery swaps, no dead unit you don't know about
Don't wait until the alarm sounds. By then, it's already late.
The real danger isn't carbon monoxide itself. It's believing your detector will warn you in time — when it's built to stay silent through the early stages.
20,000+
ER visits per year
Over 20,000 Americans are hospitalized for CO poisoning annually. Most had a detector. It just wasn't built to speak early enough.
400+
Deaths per year
An average of 430 Americans die from unintentional CO poisoning each year. Most deaths happen in winter, while people sleep.
Your body reacts before your detector does.
Carbon monoxide builds silently. The first symptoms begin long before a standard detector is required to make a sound. By the time it finally goes off, your family has already been breathing it for hours.
30 PPM — Headaches, fatigue, nausea begin. Selvanto alerts here.
50 PPM — Dizziness, confusion, difficulty thinking clearly. Your detector is still silent.
70 PPM — Most detectors are finally required to react. They can still wait up to four hours.
Firefighters see this pattern on every CO call — families who relied on a detector that "worked," but the alert came after the damage was already done. Selvanto was developed from that experience. Make the air visible earlier. Give your family time to act.
Your Detector Is Designed To Stay Silent Below 70 PPM. Ours Alerts Before 30.
The 4-in-1 RV monitor that shows you what's in the air — before your family feels it.
Plugged it in the first night at the campground and it read 0 across the board. Peace of mind I didn't know I was missing. I've had a standard detector for six years and never once knew what the actual number was. Now I check the screen before bed the same way I check the tire pressure before a trip. Should have done this years ago.
My husband ran the furnace overnight and I woke up with a headache two trips in a row. We argued about whether it was the air or just me. Plugged in the Selvanto on our next trip and watched it climb to 24 PPM with the furnace running. Our old detector never made a sound. Found out later the exhaust vent was partially blocked. $50 fix. Could have been a lot worse.
We bought a used fifth wheel last fall and the CO detector on the wall had a 2019 date on the back. Replaced it with this. The fact that I can see the number instead of just a green light changes everything. My wife sleeps better. I sleep better. We run the furnace all night now without one of us staying half awake wondering.

Frequently Asked Questions
No. Selvanto detects carbon monoxide, natural gas, and propane — all three in a single device. In an RV, you're never dealing with just one possible danger.
In an RV, one near the sleeping area and one near the propane appliances — at minimum, two. For your home, add one near the furnace or water heater and one on each additional floor. If your family sleeps there or gas burns there, it should have a Selvanto.
Most cheap detectors only trigger at high concentrations — meaning the air has already been dangerous for a while before you hear anything. No screen. No readings. Just alarm or silence. And you have no way of knowing whether the sensor is still working or has quietly expired.
Selvanto alerts before 30 PPM, shows live readings on screen, monitors temperature and humidity, and tells you when the sensor needs replacing. The real question isn't the price. It's whether you find out early or find out too late.
The sensor is built for continuous use. Selvanto also comes with a 3-year warranty for peace of mind.
Carbon monoxide mixes evenly with the air, so height isn't critical for CO detection. If you're also using it to detect natural gas, mount it higher — natural gas is lighter than air and rises toward the ceiling.
The screen shows live gas values at all times. You don't have to guess or press a test button and hope for the best. If the numbers are on screen, the sensor is monitoring.
No. No app. No Wi-Fi. No batteries. Plug it into any outlet and it starts monitoring immediately.
