Cabin air filter supplier size tables and sample plans

Define the coordination scope

Requirements review

The buyer supplies vehicle year/make/model, HVAC mounting position, OE reference for identification only, length-width-thickness, airflow arrow, media layer, seal edge, packing unit, quantity and destination ZIP. Drawings can follow after contact if they cannot travel with the form.

Supplier questions

Ask cabin air filter manufacturers for the size table used, frame and foam-seal construction, carbon-layer description if claimed, sample piece policy, minimum order quantity and packing photos tied to the quoted SKU. A workshop catalog page is not a plant-specific drawing.

Quote comparison

Separate unit cost, packing, freight, taxes, sample charges and service fees. Keep washable, particulate, split-pack and high-efficiency lines distinct so a cheaper media is not scored against a different BOM.

Order handoff

Record the approved sample identifier, unresolved fitment questions, warranty scope offered by the supplier, and which party books freight. Sample approval is not automatic batch acceptance.
