Replace your old humidfier wick filter with the new high-quality Aprilaire A12-W Furnance Humidifier Filter A-12W.

This A12 Humidifier Filter has a powdery substance that allows the water to move at a slower pace through the filter to receive the maximum amount of water to be absorbed into the air.

For the best performance and maximum humidity output, wick humidifier filters should be replaced every 30-45 days.

The harder the water, the more it will decrease the lifespan of your wick filter.

Remember to always discard your used panel filter at the end of each season.
