Protect Your Family From Harmful Pathogens

By replacing the water panel in your Aprilaire humidifier you can ensure that harmful pathogens do not build up in your humidifier.  This will keep your air fresh, breathable and pathogen free.  If your water is drawn from an underground well or any other underground water source you absolutely most replace your water panels as scheduled.

Benefits To Your Home & Health

Proper humidity is a great way to ensure a healthy respiratory system, and also helps to protect parts of your home that can be destroyed by dry weather (weather stripping, molding, paint, etc.).  It is very easy to properly maintain your Aprilaire humidifier to ensure that you experience optimal performance all the time.

Proper Maintenance of Your Dehumidifier

Your Aprilaire 12 Water Panel must be replaced once a year on average, but in cases of extreme dehumidifier use your water panel may need to be replaced as often as every six months.  Please refer to the link to the manual below for replacement instructions.

Aprialire water panels are also referred to as humidifier pads, replacement humidifier filters, and water pads.

Customer Reviews

exact fit for my Aprilaire 445

This replacement pad was an exact fit for my Aprilaire 445. It's cheap, so I don't think that changing it once a year will be a problem.
