The validity period of antibacterial performance in urban outdoor furniture typically ranges from 2 to 5 years, depending on material composition, environmental conditions, and manufacturing quality. Most antimicrobial treatments integrated into materials like polywood, aluminum, or composite lumber maintain effectiveness through regular weathering and use. Permanent solutions like silver-ion technology or copper-infused surfaces can provide protection for the entire product lifespan. Environmental factors such as UV exposure, moisture levels, and cleaning frequency significantly impact duration. Manufacturers usually certify antibacterial performance through standardized testing methods like ISO 22196 or JIS Z 2801. Regular maintenance and proper cleaning help maintain antimicrobial efficacy throughout the stated validity period.
