Breath You Take Every Moment
Protecting you and your loved ones, with a rechargeable smart CO detector.
Nef-es
Nef-es is a rechargeable smart gas detector that detects carbon monoxide leaks at ppm levels. It provides autonomous protection against stove poisoning and exhaust gas buildup.
Rapidly detects carbon monoxide leaks even at the lowest ppm levels, keeping you safe.
Long‑lasting rechargeable battery eliminates the need for constant battery replacement.
High‑decibel siren that activates for varying durations based on CO concentration (30‑300+ ppm).
Fits homes, modern offices, industrial warehouses, or enclosed parking lots—installs in seconds wherever needed.
You Can't Feel Carbon Monoxide
Carbon monoxide (CO) is a colorless, tasteless, odorless gas. It silently accumulates in many environments, from stove poisoning to exhaust buildup in enclosed garages, often being noticed too late.
False Alarms and Loss of Trust
Standard detectors cannot differentiate harmless concentrations from lethal gases, leading to frequent false alarms that cause users to ignore warnings or disable the device, creating a major safety gap.
The Nef-es Difference
Nef-es focuses exclusively on CO with an advanced sensor, analyzing ppm levels over time. It eliminates false alarms and only triggers during genuine danger.
Rapid Response at Critical Thresholds
Simple alarms sound for every gas indiscriminately. Nef-es reacts strategically based on accumulated ppm, sounding a massive alert at 300 ppm within seconds.
LED Status Indicator
A three‑color LED panel lets you visually monitor air quality and device risk level at a glance, essential for homes and industrial settings alike.
No Installation Hassle
No wiring or specialist needed. Its compact design can be securely placed from living rooms to enclosed garage entrances.
Built with ESCOM‑ES assurance, Nef-es is an elegant pillar that fully protects your living and working spaces.

Every Breath You Take Is Safe
Shield your home or workplace from silently building gases with Nef-es.
Frequently Asked Questions
Nef-es (CO) is an autonomous, rechargeable smart detector that measures invisible carbon monoxide in the air and alerts you audibly before it reaches dangerous levels.
Nef-es is calibrated exclusively for CO (carbon monoxide) – the hazardous gas from stove poisoning or exhaust buildup – and does not detect natural gas or LPG.
Yes. It operates on its internal long‑life rechargeable battery, so it continues protecting your family even during electricity outages.
The system intelligently times alerts: 30‑49 ppm after 120 minutes, 50‑99 ppm within 60‑90 minutes, and 100‑299 ppm in 10‑40 minutes.
It reacts instantly. If CO exceeds 300 ppm, the device triggers a loud alarm within 0‑180 seconds without delay.
A three‑color LED panel visually indicates normal and risk states, while exceeding thresholds activates a powerful audio siren.
No. Besides homes and offices, its robust design is suitable for industrial warehouses, logistics centers, and large enclosed parking areas.
