Product review (1 stars): smells awful for first 2 days
Smells awful for several days. It is the only filter that fits my awesome humidifier so I feel forced to purchase this item. I have resorted to running the humidifier in a locked room (with the window open) for two days before the stink subsides. Even leaving the filter unwrapped for a few days does not expel the stink. The smell is so awful that it cannot be safe or healthy.
