Partially · and the details matter. Purolator's A+ content references ISO 4548-12 at 25 microns, but the citation is on sibling SKU PBL30001, not PBL14476 directly. Community-reported Ascent Filtration ISO 4548-12 testing (cited on BITOG) shows approximately 88% efficiency at 25 microns; the actual 99% efficiency threshold for BOSS SmartFUSION media appears to be around 46 microns, not 25 microns. The CCT filtration_efficiency score reflects this gap between the marketing claim and the community-reported independent data.

Multiple BITOG (Bob Is The Oil Guy) forum members have cut open PBL14476 and reported positive construction findings: ADBV described as 'absolutely intact' and 'very soft like bubblegum' (consistent with silicone), pleats as 'laser straight,' and overall construction rated above commodity tier. These are independent community cut-opens, not manufacturer-provided imagery.

Its retail price sits below Amazon's standalone-purchase threshold for certain low-priced items, so Amazon flags it as an add-on. To buy it standalone you need a qualifying order minimum in the same cart or Subscribe & Save enrollment. Standalone one-click purchase without other items in the cart is not available.

Purolator's own marketing on the product listing is inconsistent: the lead feature bullet says 'up to 20,000 miles' and the product description paragraph says 'up to 15,000 miles.' The conservative 15,000-mile figure is used here because it is the lower of Purolator's own two numbers. No independent community long-drain cut-open of PBL14476 at extended intervals has been located to corroborate either claim.

Yes · BITOG cut-open owners have confirmed the ADBV is silicone, described as very soft like bubblegum and found 'absolutely intact.' Purolator's feature bullets also confirm: 'Silicone anti-drainback valve protects against dry starts.' Silicone is the higher-quality ADBV material in this category, more heat-resistant than nitrile.

The PBL14476 gasket is ethylene acrylic · Purolator's 'PuroSEAL' branding · per the Amazon feature bullets. Ethylene acrylic is a synthetic elastomer, not natural rubber. There is no latex allergen pathway for this product.
