I agree with the negative reviews of this humidifier. I've now gone through 2 filters and each one lasts a very short time before getting very smelly and attracts bugs. So when I clean out the humidifier to refill it there are many small dead bugs in the water. And I clean it out every other day! I tried the tip from one customer who said to throw out the filter and just tape the button on the top pressed and that seems to have worked for now. I'm so confused about why the filter even exists if it lasts for that short of a time and stinks up the room. I unfortunately do NOT recommend.
