Product review (1 stars): Poor design but vendor should provide an alternative that can ...
The pack of 3 makes absolutely no sense at all - considering the humidifier I purchased from them requires 2 filters, you MUST buy 2 packs to make it work - filters are paper and cannot - should not be cleaned in vinegar as you can with other filters - one time and they will get clogged and you have to buy more. Poor design but vendor should provide an alternative that can be reused - albeit more expensive.
