Know your air is safe — before it's too late.
VASAIKO's 6-in-1 smart detector shows real-time CO, gas, smoke, temperature and humidity on one clear display. No guessing. No alarm after the danger has already arrived.
Certified, tested, and trusted in 50,000+ American homes
Not just a beep in an emergency — a real-time readout of every threat in your air, from a brand labs trust.
What your basic detector hides from you.
CO is colorless, odorless and kills silently. Most detectors just beep — you never know if the sensor is still alive. This one shows you what's in your air, every second.
Basic Detector
- ✕ Detects CO only — no gas, no smoke
- ✕ Just a blinking light — no live reading

- ✕ Beep-only warning — too late if you're asleep

See the invisible. Sleep soundly.
Carbon monoxide has no smell, no sound, no taste. VASAIKO turns the invisible into a number you can watch — and act on — in real time.
Explore the technology →See the invisible in real time
A bright HD display shows live CO, gas and smoke levels in parts-per-million — so you act the moment they rise, not after.
Sleep through the noise, wake for the danger
An 85 dB alarm and battery backup keep watching through outages — and the clear display means no more 3 a.m. guessing.
Certified, not a gadget
Every VASAIKO is tested to UL 2034, UL 1484 & UL 217 safety standards and backed by a 5-year warranty — lab-verified protection you can trust at 3 a.m., not a cheap untested gadget.
One detector. Total peace of mind.
Built for the rooms you sleep in — and the ones you travel to.
VASAIKO 6-in-1 Smart Guardian
One alarm isn't enough. Cover every room.
Carbon monoxide builds up in the everyday spaces your family lives in. Here is where a VASAIKO should be watching.
Bedroom & Nursery
Most CO deaths happen at night. Mount one inside or just outside every sleeping area.
Living Room
Gas fireplaces and portable generators leak CO. Protect where the family gathers.
Basement
Furnaces and water heaters hide here — the top undetected CO source in most homes.
Garage & Nearby
A running car hits lethal CO in 10 minutes. Alarm on the living-side wall, 10 ft from the door.
Kitchen
Gas stoves emit trace CO. Place 15 ft from the oven to avoid false alarms.
On the Go
RVs, cabins and boats. Take protection on every family trip, not just at home.
