Which of the following is NOT a characteristic of anti-microbial finishes?

Anti-microbial finishes are designed primarily to inhibit the growth of bacteria, fungi, and other microorganisms on surfaces, which contributes to a cleaner and healthier environment. Additionally, these finishes often enhance the overall durability of surfaces by providing a protective layer that can withstand wear and tear, thus improving longevity and reducing the frequency of maintenance required.

However, improving air quality is not a direct characteristic of anti-microbial finishes. While maintaining a surface free of harmful microorganisms can indirectly contribute to a healthier environment, the essential function of these finishes is not to improve air quality but rather to provide a specific barrier against microbial growth. This distinction highlights why the assertion regarding air quality does not align with the primary characteristics of anti-microbial finishes.
