Car Air Purifier for BMW 3 Series: Rental Fleets
This car air purifier is the version most often ordered for rental fleets on the BMW 3 Series. It is supplied to a written specification covering material, dimensions, finish and packing, and that specification stays on file — so a repeat order is a reorder, not a new negotiation.
What usually goes wrong is ordinary: inconsistent hardness between lots, or warranty claims traced back to a single lot. Both come from a specification that was never written down.

Fitment notes
Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.
Ordering checklist
- Confirm the model year, market version and mounting points.
- State the duty cycle; rental fleets is not the same specification as occasional use.
- Approve a sample built from bulk material.
- Fix packing and marking before the first container.
- Inspect before balance payment.
Questions buyers ask
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
