DISCLOSURE: I was given a promotional price in exchange for an honest review of this product.

If you're looking for these filters, these WILL do the job admirably.  They fit just as well as the default, stock filters, and are infinitely cheaper.  Whether they will truly filter out everything they need to is another thing - I'm not sure, but they feel and look extremely similar to the stock filters.
