Product review (4 stars): Good price + performance
Price is the key difference between this and a factory original. Performance wise it lasts a month or two on daily use. I did notice that my humidifier " filter change indicator" only works for the first few days when I replace it with this brand of filter, which I'm not certain whether it's an indication that the filter is not up to standards or just because this is an OEM product. Regardless I'm satisfied with this product and purchase price.
