Discounts for our Honored Military Personnel

From all of us at Filter King, we would like to sincerely thank you for all of your service. We know that serving, in any capacity, demands sacrifice - often tragic, immeasurable sacrifice. There's no way we can ever properly show our gratitude. But here's a start.

All active duty personnel, veterans, and their families are eligible for a $5 discount on all Filter King products, forever. It's our way of paying your sacrifice forward.

Use the code MILITARY5 to receive $5 discount on your next order.

Thank you for your service.
