- The Shipping Cost Estimate through our freight estimator does not provide an accurate shipping cost for this item due to the very light weight and large volume of filters. Orders for more than 12 filters will require additional shipping charges. Before an order is processed you will be contacted with the exact additional cost information for approval. This is addressed in the Shipping and Will Call terms under Customer Service on the home page.
