Generalaire 990-13 Evaporator Pad

Humidifiers raise humidity levels in your indoor spaces to comfortable levels to bring moisture back into your home or office. Dry air in your indoor spaces can make you more susceptible to preventable illnesses such as dry skin, bloody noses, itchy eyes and a number of other detriments to your health. Installing Generalaire humidifier filters into your filtration system can rejuvenate your indoor space and protect your home from the dangers of low humidity.

The Generalaire 990-13 evaporator pad (AKA humidifier filter, water panel, water pad) is a critical part of your humidification system. The filter is composed of an aluminum mesh enclosed in a heavy wire frame and channeling, then coated with a super absorbent material for maximum water distribution. As water flows through the humidifier valve and comes into contact with the water pad, the humidification process begins. The evaporator pad absorbs the water. Hot, dry air from the furnace or fan coil passes through the humidifier filter and produces water vapor. The water vapor is then distributed throughout your indoor space via the forced-air duct system. This process brings moisture to your indoor environment, alleviating the effects of uncomfortable dry air.

To ensure that your whole house humidifier system is running at maximum efficiency, you should change your humidifier filter at least once per heating season. When your evaporator pad is in use for extended periods of time, the constant contact with water and foreign particulate can cause build-up to accumulate on the filter media. This will make your water panel work less efficiently and make your HVAC system more susceptible to maintenance issue. To save you time and money in the future, routine filter changes should be performed. Areas with hard water may require two changes per season to ensure peak performance.
