Aggregate ratings lean positive, with most ratings in the top two star categories, but a smaller low-star share remains and no written customer feedback is available to explain the reasons. These ratings do not establish fit or filtration performance, so check the PR1 dimensions and treat the stated performance claims as listing claims.
