IIRC, they are around $80. But it's not quite as expensive as it may sound on the surface. With the new filter system, you don't have to spend $60 per year on the disposable microfilters, and you may save another $30 - $40 per year not buying filter cleaner, so now you're withing maybe $50 per year of the previous Sundance filter regimen. The re-usable pleated filters cost around $60, and last maybe 36 months, and you don't need to buy those either, so it reduces your costs a bit more. So the difference may not be as bad as it seems on the surface. When you divide the cost difference out on a per month basis, it only works out to be a few dollars. Minor.
