Which safety device uses filters or sorbents to remove hazardous substances, including pesticides, from the air?

Algaecide (Algicide)
A device that stirs or mixes a pesticide product in a sprayer
Air-Blast Sprayer
Air-Purifying Respirator (APR)

The correct answer is: Air-Purifying Respirator (APR)

An air-purifying respirator (APR) is the correct choice as it is specifically designed to filter out hazardous substances, such as pesticides, from the air before it is breathed in. Option A, algaecide, is a type of pesticide used to control algae growth in bodies of water and would not be used as a safety device. Option B, a device that stirs or mixes a pesticide in a sprayer, does not remove hazardous substances from the air but rather is used to mix the pesticide for application. Option C, an air-blast sprayer, is also used for pesticide application and does not have a filtering function. Therefore, the best option for removing hazardous substances from the air is an air-purifying respirator.
