To keep the cost of paper filters to a minimum, we can supply 8 small envelopes, each containing 25 filters by mail. This is enough to refill the Simple Smart Filters box that contains 200 x 26 gsm filters. To keep the cost down, the refills are shipped via the postal system without tracking. We do provide proof of postage via email.

If you want to order 200 filters and have the order tracked, you will need to order the complete box, not the refills.
