Product review (2 stars): Disintegrates like the original
These wicks/filters design are flawed. Humidifiers are supposed to help alleviate symptoms associated with surrounding environments. Humidifying the air helps those that are sensitive to whats around them, or lack thereof. As humidification goes, evaporative in its simple form, is probably the best overall as it resembles what occurs naturally. Unfortunately, the mechanism in which evaporative humidifiers are designed (wicks and their materials) is poor, and this is demonstrated with this filter ad the humdifiers that use them.

These wicks disintegrate and im sure owners have touched them and seen all that black residue on your hand. Imagine all the residue that is being blown into the air? Also, when turning off your humidifier, these filters tend to get very moldy and gives off a very mildewy smell. Yes, they can be controlled by the chemicals, but thats another topic of discussion.

All in all, within days of installing, these filters get mold and mildew, and disintegrate particles into the air that you are trying to improve for the sake of whatever condition your are wanting to help.
