Decent, but it's tough on the environment.

TL;DR No published SAE J1858 or ISO 16889 test data · the 22-micron retail spec carries no named test standard. No cut-open review located; bypass is OEM-integrated into the BMW housing, and owners do not report bypass or dry-start failures.
Cartridge-style replacement element for the BMW top-mounted oil filter housing on N52, N54, N55, and N20 engines · only the paper element is replaced; housing and bypass valve stay on the engine. Media is cellulose per the product spec and manufacturer description. No independent multi-pass filtration test data located; the 22-micron retail spec carries no cited method. No cut-open review found; construction quality scored conservatively. Mann+Hummel supplies the OEM BMW filter element · the HU 816 x is the same part without BMW packaging. No fitment failures documented by owners.
Right pick for a BMW N52/N54/N55/N20 owner on 5,000-7,500 mile oil changes seeking OEM-equivalent construction below dealer pricing. Skip for extended-drain programs · a full-synthetic extended-drain filter element is the appropriate choice.
No chemical exposure pathway · cartridge oil filter element is a passive mechanical accessory with no SDS. Spent elements contain residual motor oil, a hazardous waste in most US jurisdictions; drained elements are accepted at most automotive parts stores.
Yes · Mann+Hummel is the OEM manufacturer that supplies BMW's oil filter elements. The HU 816 x is the same filter element sold without BMW packaging. OEM part numbers 11427566327, 11427541827, 11427854049, and others cross-reference to this part.
The HU 816 x kit includes the filter element, an O-ring, and a drain plug washer (copper). These are visible in the product images · the element is a black cylindrical paper cartridge with a green secondary O-ring also included.
The HU 816 x fits BMW models on the N52, N54, N55, and N20 engine platforms, including the 1 Series (128i, 135i), 2 Series (228i, M235i), 3 Series (320i, 328i, 335i), 4 Series (428i, 435i), X1, X3, X5, X6, and Z4, among others. Verify fitment against your specific year and model before ordering.
No · the HU 816 x is a cartridge element and does not incorporate an anti-drain-back valve in the element itself. The BMW oil filter housing integrates the drain-back mechanism and bypass valve. This is the standard architecture for BMW cartridge-style filter systems. No dry-start or slow-pressure-build complaints appear in the available owner reviews.
The Amazon listing for Mann-Filter HU 816 x Cartridge Oil Filter carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including rubber, vinyl, plastic, and metal automotive parts — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive accessory, Mann-Filter HU 816 x Cartridge Oil Filter has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
