Get Isopod Negative Pressure

They are a common method of infection control and are used to isolate patients with contagious, airborne diseases such as measles, tuberculosis, SARS, MERS, and COVID-19.

Disadvantages of Negative Air Pressure Too much negative air pressure in a house can increase energy costs by drawing in the hot air in winter and cold air in warm seasons. It can also lead to dry indoor air that can result in dry skin, itchy eyes, and nose bleeding.

Negative pressure rooms, also called isolation rooms, are a type of hospital room designed to prevent airborne microorganisms in the room from entering hallways and corridors.

Negative pressure rooms must undergo at least 12 total room air changes every hour. They need to maintain a negative pressure differential of at least 0.01''. Exhaust from these rooms and any connected anterooms or toilet rooms needs to travel directly outdoors with no chance of contaminating exhaust from other spaces.

Ordinarily, negative air pressure isolation rooms are used as prevention rooms, while positive air pressure isolation rooms are used for protection. Therefore, negative air pressure keeps pathogens in, and positive air pressure is intended to keep pathogens out.
