Product review (5 stars): Works As Expected
Was having a hard time finding these locally. These are OEM quality. For me their mode of failure was always bacteria smell. I throw them away at the end of the season anyway and start with a new set the next year. But I was having to replace them occasionally because of the smell. When I would open up the unit, these filters would be discolored and stinky slimy. I tried Humidifier Bacteriostatic Water Treatment. Found this on Amazon as well. Just put a cap full in the water reservoir every couple of changes and the filters stay nice all season.
