Yeah DEMCIFlex seems like a good manufacturer. I emailed them asking if they could sell just one of the 3 filters that come as a set for the HAF 932 (only the bottom one is needed for the HAF X). They replied promptly and courteously saying they could sell it for $8 w/ shipping included to the US, and they're way down in friggin So Africa! I call that pretty good pricing and service. Only thing I worry about is the durability of the mesh material itself, which is polyester as far as I recall. Polyester doesn't absorb moisture, but it's not exactly known as a durable fiber.
