Product review (1 stars): Not correct width -- company should refund my $
Am very disappointed in this filter. It is not the same size as the filter that came with my V3100 humidifier. It lacks about 4 inches of width to fill the width of the water tray it sits in. I have to use it for a couple days before I can get to CVS to buy the correct one, otherwise I would return this one. It may be $2 cheaper than the CVS one, but if it's not the right size the $2 savings is worthless.
