## Before you buy

- The listing says 90% of airborne particles are trapped, while customer feedback describes effectiveness as cleaning 94% of allergens.

Customer feedback also reports both successful and unsuccessful fit, as well as some damaged arrivals, so compare the actual dimensions with your existing filter and inspect delivery condition.

These experiences make exact dimensions worth checking against the listed actual size. The reported impressions do not establish particle-removal performance.
