Andria A Chicago , IL October 06, 2018 Appliance: Model GE ZONELINE 2500 A/C filters no longer available from GE The GE Zoneline unit in my new condo is a discontinued model. However, I still needed new filters and they're not available from GE. Fortunately, AppliancePArtsPros has them! The sizing was confusing to me but when I called AppliancePartsPros, the reps were extrememly helpful. My new filters arrived just 2 days later and slid in perfectly. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
