Product review (2 stars): Too flimsy to wick well.
This is cheaper,but it is no bargain. I could never get the humidity to 40% with this filter. I went back to genuine Honeywell filters, which can get humidity to 50%+. It's important to understand this is not just a filter; it is a wick that holds the moisture to be circulated by the fan. This knock-off is too flimsy to be up to that task.
