FilterEasy accepts all major credit cards for payment. When you update your information and select your interval, we will charge your card on file upon shipment. Even though we give you a convenient breakdown of your monthly cost on the site, you are charged only when your filters leave our warehouse (With a few exceptions including custom filters). You will see a $1 pending charge on your account upon signing up, but this is only to verify your card for future orders. This $1 falls off of your account automatically.
