Large Replacement filter This is as good as the original. I've used one of these filters for over four months now and there are no signs of deterioration or mildew anywhere. I will have two helpful tips to consumers: (1) Make sure you have an antibacterial additive in your humidifier every time you fill your tank and (2) always rotate the filter up and down every time you water. This will greatly increase the life of your filter. Moreover, Twin Pack is a good buy! Replacement of filters, I have one of these a few months ago and it works fine. Then I got one second without it, and my account was charged. I contacted the seller and I await a response.
