VASAIKO

PPM means parts per million — the standard unit for carbon monoxide in the air. A basic alarm only beeps once CO crosses a danger line. VASAIKO shows the live number, so you see it climb from 0 and can act before the alarm ever sounds.

A basic alarm is blind — it stays silent until CO is already dangerous, then just beeps. VASAIKO shows the real-time reading, covers 6 hazards in one device (CO, natural gas, smoke, temperature, humidity, combustible gas), and keeps watching through power outages with battery backup.

Follow NFPA guidance: one detector on every floor and inside or just outside each sleeping area. Keep it about 15 ft from the kitchen oven to avoid false alarms from cooking. Mount one in the bedroom, living room, basement and garage-side wall.

The live display is your friend here — if it's just burnt toast, you'll see the number stay low and know it's not CO. Place units 15 ft from ovens and bathrooms, and the 85 dB alarm only triggers on a genuine CO rise.

The 6-in-1 Guardian includes battery backup, so it keeps monitoring through blackouts — exactly when portable generators make CO risk spike.

Every VASAIKO is tested to UL 2034, UL 1484 & UL 217 standards and backed by a 5-year warranty. The CO Alarm Pro uses a 10-year sensor. We stand behind the device that protects your family at 3 a.m.
