If you need to cancel or modify an order, please call us as soon as possible. We strive to ship within 24 hours, and once your order has shipped, if your order cannot be rerouted, you will need to use our return process instead. 


If you need to return a case of filters, please notify us at your earliest convenience, and no later than 30 days after receipt. Buyer is responsible for return shipping. When we receive your returned product, if it is still in good condition, we will issue a refund for the price of the items to your original payment method, minus a 20% restocking fee. Shipping charges are not refundable.

Address Errors

If you need to correct a destination address, please call us immediately! 

Capital Air Filters, Inc. is not responsible for any lost package that is incorrectly addressed due to customer error. We generate our shipping labels from the information the customer provides, so if you enter an incorrect or incomplete address (incorrect zip code, missing apartment/suite/office number/name etc.) and your package is lost, Capital Air Filters, Inc. is not responsible.

If your order has already shipped and must be re-routed by the carrier, you will be charged an additional fee. 

If you decide you no longer want the order and refuse the package, a refusal fee will be deducted from your refund. (The refusal fee is calculated from UPS return charges.)

If you contact us by phone after your order has been placed regarding an incorrect or incomplete shipping address, we will make every effort to correct your information prior to your package being shipped. However, once your package has shipped, we may not be able to correct or re-route your shipment. If your order is lost or delivered to the incorrect address, Capital Air Filters, Inc. is not responsible.
