Product review (3 stars): Not the same as the filters that came with new humidifier
We have well water with 2 filters for rust/iron and for hardness. I realize this factors in to the lifespan of the filter, the salt build up is pretty obvious. Regardless, we used the original filters from Oct-Jan before they were ready to pitch, and the replacement has been in less than a month and already the build up is concerning. There have been no changes to our water and the humidifier has been cleaned several times. The original filters also seemed to help with the noise, because now we've noticed that it sounds much louder. I can't speak too poorly of them, because I don't think I have any other options, I'm just disappointed that they're a lesser quality than the originals!
