Product review (4 stars): If changed out regularly this works great with my Holmes
If changed out regularly this works great with my Holmes.  Highly recommend this along with the anti-bacterial used when running a humidifier.  Have bought over the course of 2-3 years.  Good investment/product.  Got moldy faster than I wanted, but I don't know if that could even be helped.  I had to change these more often than I wanted (like more than 1x month).  This is not a bad product though.  It's a decent investment and works well.
