** Shipping is calculated by weight **

For filters, parts, and accessories, we use US Postal or UPS Ground services depending on shipping address. It normally takes about 4 to 6 business days for delivery from California to the East Coast.  Please use the shipping calculator on the shopping cart page to obtain an estimate of shipping rate.  It is 95% accurate on most continential addresses.  We reserve the right to make adjustment or cancel order if the estimated rate does not cover actual shipping of the order.

APO/HI/AK/PR/GU/PO box customers: Postal service is utilized, and depend on the filters ordered, sometimes we use flat rate boxes or our own boxes. Flat rate boxes are cheaper and the overpayment will be refunded. International buyers: Either UPS or Postal service is utilized. The shipping calculator on the website is 95% accurate. However, we reserve the right to make adjustment or cancel order if there is variance on the actual shipping cost.
