How to choose
Consider Filter Efficiency
Focus on the CADR rating for effective air cleaning. Higher CADR values indicate better performance at removing smoke, pollen and dust.

More expensive models often include additional features like HEPA filters or activated carbon layers. Evaluate your needs versus cost to find best value.
Avoid Overlooking Maintenance
Check filter replacement costs and frequency. Frequent replacements can negate initial savings on cheaper purifiers over time.
