Product review (1 stars): BestAir Ruined a Perfectly Good Filter
BestAir effectively ruined what used to be a fine filter by adding their "Perfect Blue" to it.  This thin layer of blue filter material is supposed to absorb chlorine in the water.  What it does is turn the water and the filter blue, and stain all the plastic it comes in contact with.  As a result, the filter clogs way sooner than it used to, and at that point, doesn't pull any moisture up for the humidifier to fan into the room.  What a STUPID "improvement".  I will never by a BestAir filter again.
