Product review (3 stars): Honeywell Filters/Wicks
The filters I received were not exactly as you will see pictured.  The outside of the filter had a layer of tight meshed blue material.  I can only guess that it functions as an air filter.

However this filter did not last as long as other generic filters I have purchased.

After only a couple of weeks the filter built up deposits and the top of the filter, which is the part that releases water into the air, stayed dry.

If you wonder, I have a particulate filter and a water softener on the water supply to my house.  And, as I said, the generic filters (not Honeywell branded) lasted longer.
