Comments about Sunpentown Replacement ION Exchange Filter F-4010:
Received the product quickly. I typically replace my SU4010's ION Exchange Filter seasonally. This product helps stop white dust from forming and keeps my humidifier in good shape. Easy to install. The only thing I wish is that it would last longer.
Bottom Line Yes, I would recommend this to a friend
