What is the range of an air purifier's effectiveness?

The effectiveness of an air purifier can vary widely depending on several factors, including the type of air purifier, its design, and the specific contaminants it is intended to address. Generally speaking, most air purifiers are designed to be effective within a specific room size, usually ranging from 100 square feet to over 1,000 square feet. The effectiveness is often linked to the Clean Air Delivery Rate, or CADR, which measures the volume of filtered air delivered by the device in cubic feet per minute. When assessing the range of effectiveness, it is important to consider factors such as the air changes per hour, which indicate how many times the purifier can filter the entire volume of air in the room within an hour. In addition, air purifiers equipped with HEPA filters are particularly effective at capturing small particles, including dust, pollen, and pet dander, which can significantly improve indoor air quality. It is also worth noting that the placement of the air purifier within the room, as well as air circulation patterns, can impact its overall effectiveness.
