Product review (4 stars): Replacement Filters
The filter design is pretty straight forward so I didn't expect any isues.  I  have began using one of the 4 replacement filters I purchased and it is working fine.  One thing I did notice is that the size of the filters varies slightly from one to the other.  I am sure this is because they were cut to size from a larger piece of bulk product.

The price was great as was the overall value.

I will buy this product again and would recommend it to a friend.
