Wick Filter (Set of 2) for SU-4023B

The Wick Filter (Set of 2) is a white humidifier accessory for the SU-4023B, suited to owners of that model who need replacement wick filters for routine maintenance.

Recommended For

• Owners of the SPT SU-4023B replacing a used wick: Sunpentown recommends replacing the filter about every three months.
• SU-4023B users whose wick is scaled or contaminated and needs rinsing or replacement to maintain humidifier performance.
• SU-4023B owners who want a spare pair of replacement wicks ready for routine or seasonal humidifier maintenance.

Real-World Use Scenarios

• During regular use of an SU-4023B, replace the wick about every three months as Sunpentown recommends; a fresh wick helps the humidifier maintain its intended moisture output.
• If the wick develops yellowish-white limescale during use, rinse it as directed and replace it when needed; Sunpentown notes that scale can reduce humidification performance.
• If the SU-4023B is humidifying poorly or stops working, check and rinse a contaminated wick first; replace it if cleaning does not resolve the issue.
• For seasonal humidifier use, keep a replacement wick available so the SU-4023B can be returned to service with a fresh filter when its existing wick is scaled or worn.
• When storing the humidifier for a long period, remove and air-dry the wick; use a replacement later if the stored filter is scaled or no longer supports normal humidification.
