Common Question: How often should I change my Vapor Pad?
Answer: Your Vapor Pad is constructed using an expanded aluminum base. The aluminum base is coated with a hydrophillic material that absorbs water. As warm air from your furnace passes through the Vapor Pad®, the water contained in the coating evaporates to provide your home with humidity. Over time, water deposits build up on the Vapor Pad®, preventing warm air from passing through. If you wash the Vapor Pad® in an attempt to remove the deposits, you'll also wash off the hydrophillic coating. Your humidifier is then unable to provide humidity to your home.
Common Question: How often should I change my Vapor Pad?
Answer: You'll want to replace your Vapor Pad® 1-2 times per humidification season.
