What to know before buying

Listing details to confirm

The listing says 90% of airborne particles are trapped, while customer feedback describes effectiveness as cleaning 94% of allergens. These are differently worded, unverified claims and should not be treated as equivalent performance measurements. 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.
