Product review (1 stars): Filter is MWFA, not MWF. There is a difference.
This item is not a true MWF filter. Item description reads it's MWF, but the actual product is MWFA, which is of lesser quality/value (see GE's website for a description of MWF vs MWFA). It's basically a "lite" version of the MWF filter and can be purchased direct from GE for only $99 with free shipping.
