Best Air Purifier For Carbon Monoxide (Top 5 Products)

The problem with carbon monoxide is that the gas is completely odorless and colorless. You can detect it neither with your nose nor eyes nor your tongue. This means you can get exposed to it without even knowing. The danger of heavy exposure to carbon monoxide is enormous. CO molecules displace the oxygen when they get in the air. The poisoning can start when people inhale such poisonous air. Even worse, the symptoms of CO poisoning are similar to the flu.

The Centers for Disease Control and Prevention reports that over 400 people in the United States died from CO poisoning. Over 300 people with symptoms linked to CO exposure ask for emergency help each year.

Source control and good ventilation are some of the ways to reduces carbon monoxide and other VOCs (volatile organic compounds) in your air.

If some of these options are limited, it is highly recommended to use an air purifier. However, not every air purifier will help you reduce carbon monoxide. You need to look for a product with active gas and odor removal.

What Are Carbon Monoxide Sources In Our Home?


Whenever you burn any material, you produce unnecessary CO. The main sources of carbon monoxide in our homes are fuel-burning appliances. Another common problem is attached garages. The most common fuel-burning appliance devices that can cause unnecessary CO exposure are water heaters, clothes dryers, boilers or furnaces, gas and wood-burning fireplaces, stoves, tobacco smoke, ovens, motor vehicles…etc.

Other VOCs in the air come in form of vapors and gases. The sources of these VOCs are many. From perfumes, paints, cleaning products, air fresheners… To activities such as cooking, smoking, burning wood.

Toluene, benzene, formaldehyde, ethylene glycol… Are some of the most common VOCs. Long exposure to CO and VOCs can cause health issues. Also, it grows the risk of getting cancer.

Technologies for reducing VOCs, gases, and odors are chemical adsorption, plasma, ozone generator, and photocatalytic oxidation. Chemical adsorption is commonly used in air purifiers. It uses activated carbon to remove the VOCs in the air.

What Is An Air Purifier And What Should You Look For?


An Air purifier is a device made for improving indoor air quality. They are good for removing pollutants like pollen, dust, allergies, pet dander, odor… It depends on the air purifier filter. There are a lot of different particles in the air that can cause problems.

An air purifier works by filtering air and trapping pollutant particles. The air purifier’s internal fans take the air in your room. That air goes through a combination of filters. Particles like dust and pollen are solid. Unlike particles like carbon monoxide or odor. Some air purifiers have more than one filter and try to catch every pollutant in the air.

You should look for an air purifier that has a thick layer of activated carbon. Your air purifier needs to be effective against VOCs. Some of the common absorbing materials: activated carbon, zeolite, activated alumina, potassium iodide, earth minerals.

Try avoiding ozone generators. Yes, they are great at neutralizing VOCs in the air. But ozone generators are not for residential spaces. Also, try avoiding air purifiers with filters like Plasma or PCO. They are slower, and even worse, produce ozone.

For easier air quality control look for an air purifier that has a built-in VOC sensor. Devices with such sensors will automatically control the air quality. They adjust the fan speed based on the information of the sensor.

Measure your room and check the sq ft cover are of your air purifier. The air purifier needs to be appropriate for your room size.

Where To Place Your Air Purifier?


The best way is to put it near the source of pollution. If you think your fuel-burning appliances are causing problems, place them near them. The closer they are to the source of the problem, the quicker they can get rid of it.

It is recommended to lift your air purifier off the ground.  That is because of the air circulation directions. The air purifier can clean your air horizontally if you put It on the ground.  But if the device is too low, it can not cover the vertical air circulation.

It is best to look for the highest airflow. Prevent the air from carrying the pollutants.

Do not put it in the corners and try not to block it. Your air purifier needs to cover your whole room.

Also, do not place it too close to other electronic devices. Some of your devices could operate on the same wavelength. This means they can interfere with each other.
