Product review (4 stars): Honeywell OEM air washing wick filter
Filters work but: I have been following their recommendation to clean the filter after each use (in my case, it is used at night). I place them in a mild solution of Dawn, and move them gently in the water -then air dry them. I find that the filters, after 3 weeks or so of use, become "saggy" and need replacement. Would want that they used a more durable material.
