Product review (4 stars): Humidifier filters are a good product at a reasonable price
These filters are of good quiality. Their construction is exactly the type that came with the humidifier. They are also not that expensive. I have a lot of minerals in my water here and these filters manage to attract the minerals quite well. If the filter is not cleaned at every change of water, its useful life is shortened. But I have no complaints as they did the job required to operate my humidifier.
