Product review (1 stars): Not universal
I bought these as a universal for a starry night Vicks V3700.  They are NOT universal.  I tried what others suggested and wetting them and squeezing them to fit.  It didn't work.  I cut them and tried to adjust the fit.  (they are about 1.5 sizes too big), That didn't work.  Within one week they became slimy and black, despite changing the water every 2 nights, and cleaning the humidifier.  Now, I don't know where to get the real filters.  Don't waste your money.  When you buy your humidifier, keep ALL instructions and buy directly from the company.  I tried that too and couldn't do it, but I won't buy these again.
