Why Is Clean Air Delivery Rate (CADR) Important for Air Purifiers?

Clean Air Delivery Rate (CADR) is crucial for air purifiers because it indicates the efficiency of the device in removing specific airborne pollutants. CADR measures the volume of filtered air that an air purifier delivers, specifically for smoke, pollen, and dust. A higher CADR value means the air purifier can clean the air more effectively in a given time.

According to the Association of Home Appliance Manufacturers (AHAM), CADR is defined as the rate at which an air purifier can remove particles from the air in cubic feet per minute (CFM). The organization sets the standard for testing and reporting CADR, ensuring that consumers can make informed decisions about air purifiers.

CADR is important because it helps consumers understand the performance of air purifiers. Several factors affect CADR, including the size of the room and the type of pollutants present. For example, a large room requires an air purifier with a higher CADR to effectively clean the air, while smaller spaces may need lower CADR values. Different air purifiers may excel at removing specific types of pollutants. A purifier might perform better in removing smoke particles compared to pollen or dust.

Technical terms involved in CADR include “filtration efficiency” and “air exchange rate.” Filtration efficiency refers to the ability of the air filter to capture particles of various sizes. Air exchange rate is the frequency at which the air purifier can replace the air within a specific space. These factors play a role in determining CADR and overall effectiveness.

The mechanisms involved in CADR measurement include particle filtration, where air passes through filters that trap pollutants. High-efficiency particulate air (HEPA) filters, for example, can capture 99.97% of particles that are 0.3 microns in diameter or larger. The clean air is then released back into the environment.

Specific conditions, such as room size and pollutant concentration, influence CADR effectiveness. In a smoke-filled room, an air purifier must have a high CADR to sufficiently reduce pollutant levels. Conversely, in a room with minimal pollution, even a lower CADR purifier may maintain air quality effectively.
