Product Description

Premium refrigeration depends on both water purity and air quality. The Sub-Zero 4204490 Water Filter & 7042798 Air Cartridge Combo Pack delivers complete, factory-approved filtration to help protect taste, freshness, and appliance performance.

Designed for seamless compatibility with Sub-Zero refrigerators, this genuine OEM combo addresses two critical areas at once:

• Water filtration for clean, clear ice and great-tasting water
• Active air purification to reduce odors and slow food spoilage

Replacing both components together helps maintain peak performance and simplifies routine maintenance.

Sub-Zero 4204490 Water Filter – Clean Ice & Better-Tasting Water

The Sub-Zero 4204490 water filter is engineered for refrigerators with built-in ice makers. It reduces common impurities—such as chlorine taste and odor, sediment, and other contaminants—so the water used to make ice stays clean and fresh.

  • Clear, better-tasting ice
  • Reduced unwanted odors
  • Consistent performance of the ice maker
  • Recommended replacement: Every 6 months
Sub-Zero 7042798 Air Purification Cartridge – Active Freshness Protection

The 7042798 air purification cartridge goes beyond deodorizing. Using advanced air-scrubbing technology inspired by aerospace research, it actively cleans refrigerator air every 20 minutes.

  • Odor-causing molecules
  • Mold, bacteria, and viruses
  • Ethylene gas (accelerates ripening and spoilage)

This updated part 7042798 directly replaces the older 7007067 with the same reliable fit and performance.

Key Benefits of the Combo Pack
  • Complete Filtration Solution: Water + air purification in one package.
  • Genuine OEM Components: Factory-certified for exact fit and reliability.
  • Cleaner Ice & Water: Helps reduce impurities and improve taste.
  • Fresher Food Longer: Active air purification helps slow spoilage.
  • Easy Installation: Tool-free replacement for both components.
  • Ideal for Routine Maintenance: Replace together for best results.
Compatibility

This combo pack is compatible with all Sub-Zero refrigerator models, including:

  • Built-In Refrigerators
