Question

Which type of air filter removes vapours and gases:

A) Mechanical filter
B) Electronic air cleaner
C) Air washers
D) Charcoal absorbers

Answer 1

Charcoal absorbers are the type of air filter that removes vapors and gases, using activated carbon to adsorb the molecules of the gases.

Step-by-step explanation:

The type of air filter that removes vapors and gases is D) Charcoal absorbers. This type of air filter is designed specifically to trap gases through a process called adsorption. Charcoal, or activated carbon, is commonly used because it has a large surface area which can bond to the molecules of the gases and remove them from the air stream. Other types of filters such as Mechanical filters including HEPA filters, Electronic air cleaners such as electrostatic precipitators, and Air washers are effective in removing particulate matter, but not gases or vapors. For instance, HEPA filters are excellent at capturing microbes, endospores, and viruses, while electrostatic precipitators use charged plates to remove particulate pollutants. However, for gases and odors, nothing beats the effectiveness of Charcoal absorbers.
