Can air purifiers detect carbon monoxide

There are many air purifiers on the market that can detect the concentration of carbon monoxide. Carbon monoxide (CO) gas is a colorless, odorless, non-irritating, toxic gas that cannot be perceived by the five senses, and can inhibit the oxygen-carrying capacity of the blood. Air purifiers installed carbon monoxide sensor can only detect indoor carbon monoxide content, can not remove . Being able to monitor the level is also significant in that when the value is too high, occupants can open windows and ventilate the room to avoid the risk.

Hazards of Carbon Monoxide

Carbon monoxide (CO) is a colorless, odorless, poisonous gas that interferes with the oxygen-carrying capacity of the blood. Carbon monoxide is produced by any inadequately burned carbon-containing fuel, such as coal, natural gas, and oil. Especially in winter when heating is done by fireplaces, the concentration of carbon monoxide in the room can be very high if there is no good ventilation or proper venting. Carbon monoxide reduces the supply of oxygen needed for transport to body tissues by binding to blood red blood cells, leading to tissue hypoxia and even death. The average person has no self-awareness of poisoning, and may be unconscious or even severely impaired or even dead when discovered, so it is known as the “invisible killer”. Organizations such as the U.S. Consumer Product Safety Commission have warned the public about the presence of the deadly toxin, carbon monoxide, in homes.

Sensors in Air Purifiers

Air purifiers are an increasingly important device in modern life. They can effectively purify indoor air and provide a healthier, fresher living environment. Sensors are a key and indispensable component for efficient air purification. The sensors involved in air purifiers include PM2.5 dust sensor, formaldehyde sensor, TVOC sensor, temperature and humidity sensor, CO sensor, CO2 sensor and so on.

Symptoms of Carbon Monoxide Concentration

The following shows the reaction time and symptoms that a healthy adult may experience after inhaling CO at different concentrations:

– 50ppm: The maximum concentration that a healthy adult can tolerate within eight hours.

– 200ppm: slight headache and weakness after 2-3 hours

– 400ppm: forehead pain within 1-2 hours; life-threatening after 3 hours

– 800ppm: dizziness, nausea, cramps in 45 minutes; unconsciousness in 2 hours; death in 2-3 hours

– 1600ppm: headache, blurred vision, nausea within 20 minutes; death within 1 hour

– 3200ppm: headache, blurred vision, nausea within 5-10 minutes; death within 25-30 minutes

– 6400ppm: headache, dizziness, nausea in 1-2 minutes; death in 10-15 minutes
