Rating : - Fits Well - Close Facsimile to Filter that Ships with Unit
Overall I'm happy with these filters - but if you compare the filter material with that of the filter that shipped with the unit initially, it is not exactly the same quality - which surprised me because I thought it would be exactly the same. Nonetheless, this is a good, low price way to buy the filters.
