Product Details

• Article Number: CU 1721-2 — Mann-Filter premium particulate cabin air filter from the professional CU-series range. The "CU" prefix designates Mann-Filter's particulate-only cabin filter line ("Combi Universal"), the standard specification without activated carbon impregnation. The "-2" suffix indicates this is the set version (containing the multiple filter elements required for a complete service).
• Filter Type: Particulate Filter — pleated paper media that captures pollen, dust, mould spores, brake dust, and PM2.5 particulates from incoming HVAC air. Single-layer construction without activated carbon — ideal for customers wanting effective particulate filtration without paying the premium for odour-absorbing carbon.
• Vehicle Equipment: For vehicles with AUTOMATIC climate control — designed specifically for BMW X3 F25 variants fitted with automatic climate control / dual-zone climate.
• Quantity Unit: Set — sold as a complete service set, covering the full cabin filter requirement for the BMW X3 F25.
• Length: 164 mm — outer dimension of each filter element.
• Width: 90 mm — outer dimension. Notably narrower and slimmer than the Mann CUK 19 004 (188×187×25 mm) — confirming this is for a DIFFERENT cabin filter location on the F25.
• Height: 30 mm — depth profile.
• Fitting Position: BEHIND THE GLOVE COMPARTMENT — accessed by folding down the glove box and releasing the retainer clips. ⚠️ This is DIFFERENT to the engine-compartment-mounted CUK 19 004 filter. The BMW X3 F25 has cabin filter access in two possible locations depending on production variant — make sure customers verify their access location before ordering.
• Version with Active Carbon: Article No. CUK 19 004 — if customers want activated carbon (odour absorption + harmful gas filtration) instead of particulate-only filtration, the upgrade product is available separately. Already in your catalog.
• Function: Cleans air entering the cabin through the HVAC system, capturing airborne irritants (pollen, dust, smog, brake dust, PM2.5). A particulate-only filter without activated carbon — suitable for customers in less polluted driving environments or those prioritising cost-effective filtration over odour control.
• Service Recommendation: Mann-Filter recommends replacement at every major service interval — typically every 20,000–30,000 km or every 2 years under European driving conditions. For Tanzanian driving conditions (dusty roads, frequent city traffic, high humidity), consider shortening to every 12,000–15,000 km.
• Condition: New — factory-sealed in Mann-Filter OE packaging.
• Manufacturer: MANN-FILTER (Mann+Hummel) — German OE supplier founded in 1941. Mann+Hummel supplies original-equipment cabin filters directly to BMW factories.
• OEM Cross-References: BMW 64 11 9 237 159, BMW 92 37 1 59 — direct equivalents to these original BMW part numbers.
• Vehicle Compatibility: Designed for the BMW X3 F25 with the behind-the-glove-compartment cabin filter housing variant. Always verify against your vehicle's VIN, existing filter dimensions, and access location before purchasing.
• Quality Tier: Premium OEM-quality — Mann-Filter supplies BMW's factory cabin filters, identical specification to genuine BMW filters.
