Shipping & Delivery

How are shipping charges calculated?

Shipping is calculated automatically before you finish paying for your order. These charges are based on using UPS Ground delivery. For the shopper’s convenience, Keller uses a flat rate shipping charge based on the product weight and box size. For any questions regarding shipping rates, please contact us at

When can I expect my order to ship?

All items listed in the online store are typically in stock items. Smaller items like filter replacements will typically ship within a day or two after an order. The larger filter systems will normally ship in a 3-5 day time period. The products are shipped out of our world headquarters located in Massachusetts.

Does Keller Products ship internationally?

Keller Products does ship internationally. There may be duties or taxes that would be applied to the cost of the order. There may also be additional documentation requirements necessary to ship internationally. If you are located outside the United States, please contact us at to confirm shipping costs and documentation requirements.


Customer Satisfaction Is Our Goal

If, after purchasing, you decide the products will not satisfy your requirements you can return them. Complete refund or credit will be issued for unused and unmarked items returned within 10 days of receipt, not including shipping charges. Defective items will be either replaced or repaired. Refunds do not apply to products that have been used and are not saleable as new. Please contact for a Return Authorization.

What do I do if I receive an order damaged?

Please take extra care to make sure the box or pallet (truck shipments) is delivered in good condition before you sign for it. Keller Products can not accept responsibility for damaged items once they have been signed for in good condition. If you find that after you sign for package there is concealed damage, please contact for instructions.
