Question

These respirators cleanse a contaminated atmosphere as ambient air passes through an air cleansing element. True or False?

Answer 1

Respirators, such as HEPA filters, cleanse a contaminated atmosphere as ambient air passes through an air cleansing element.

Step-by-step explanation:

The statement is true. Respirators, such as HEPA filters, cleanse a contaminated atmosphere as ambient air passes through an air cleansing element.

For example, HEPA filters are commonly used in hospital ventilation systems and biological safety cabinets in laboratories to prevent the transmission of airborne microbes. These filters have an effective pore size that captures bacterial cells, endospores, and viruses as air passes through, removing them from the air.
