Product review (1 stars): Garbage
For a long while I was buying this product left and right for the two humidifiers I have that take it. No matter what I did, nothing would extend the life. It would work great the first day and quickly fizzle. For a long while I thought it was just my water. The black mesh shield or whatever you want to call falls apart and turns into a sandy sediment polluting the water and preventing absorption - requiring me to constantly rinse out the tub. Even if that weren't occurring, the wick itself just goes to hell quick anyway, unable to absorb and simply falling apart. I tried frequently rinsing it, cleaning it, tried just about everything to prolong its life - it's just garbage, especially for the price. I found a generic brand replacement made out of a synthetic polymer instead of this paper garbage that costs about $8 more but lasts months instead of days.
