What to know before buying

Listing details to confirm

The listing presents nominal dimensions of 10 x 24 x 1 inch and actual dimensions of 9.75"x23.75"x0.75". Customer feedback also includes reports that the actual size differs from what was advertised, alongside positive fit reports. Confirm the dimensions of your existing filter and slot before purchase. The 95% particle-capture figure and up-to-three-month service interval are manufacturer claims, not independently verified performance results.

Customer feedback describes the filter as working well, with a specific mention of dog allergens, and includes positive comments about fit. It also reports that several customers found the actual size significantly different from the advertised dimensions. That makes size confirmation especially important for a replacement filter, even though the listing provides nominal and actual measurements. Aggregate ratings are generally positive, but they do not resolve the reported sizing concern.
