Why Is It Important to Consider Air Change Rate When Choosing an Air Purifier for VOCs?

It is important to consider air change rate when choosing an air purifier for volatile organic compounds (VOCs) because this measurement indicates how effectively an air purifier can replace or clean the air in a given space. The air change rate, expressed in air changes per hour (ACH), reveals the number of times the air in a room is fully exchanged with clean air within one hour. A higher ACH means more frequent air purification, which can lead to better removal of VOCs.

The U.S. Environmental Protection Agency (EPA) defines air change rate as the frequency at which the air within a defined space is replaced by outside air. According to the EPA, achieving a high rate of air exchange is essential for maintaining indoor air quality, particularly in spaces where VOCs are present.

Understanding the importance of air change rate helps clarify its impact on VOC removal. VOCs are common indoor pollutants emitted from sources such as paints, cleaning agents, and furniture. When an air purifier has a high air change rate, it can quickly reduce the concentration of these harmful substances in the air. For example, if a room has a high level of VOCs, an air purifier that performs three air changes per hour will significantly lower VOC levels compared to one with only one air change.

In technical terms, the air change rate affects the effectiveness of filtration. High-efficiency filters, such as HEPA filters, capture particles effectively, while activated carbon filters neutralize gases and odors. However, if the air change rate is low, pollutants will accumulate faster than the air purifier can remove them, diminishing its effectiveness.

For instance, in a small office space where several aerosol-based products are used, a purifier with an ACH of 5 may be ideal, as it replaces the air five times in an hour. Conversely, in larger spaces where products that emit VOCs are not regularly used, a lower ACH may suffice. Identifying the specific use case helps in selecting an appropriate air purifier that can effectively tackle VOCs based on the air change rate.

Factors like room size, occupancy, and usage of VOC-emitting products impact the needed air change rate. For example, a newly painted room would require more frequent air changes to clear harmful fumes quickly. In contrast, a rarely used spare bedroom may need less frequent air exchanges. Understanding these conditions promotes better decision-making regarding air purification needs.
