InSinkErator CG Evolution Septic Assist Bio Charge Replacement Cartridge Review

If you own an Evolution Septic Assist garbage disposal, maintaining it with the right replacement cartridge is essential for optimal performance and longevity. The InSinkErator CG Evolution Septic Assist Bio Charge Replacement Cartridge offers a natural, enzyme-based solution to keep your septic system running smoothly while breaking down food waste efficiently. In this review, we’ll explore why this cartridge is a worthy investment for any kitchen with a septic assist disposer.

Key Features

• Citrus-Scented Enzyme Treatment: The cartridge contains a natural microorganism blend that helps break down food waste, leaving behind a fresh citrus scent that keeps your kitchen smelling clean.
• Automatic Dispensing: It releases enzymes automatically every time the septic assist disposal is activated, ensuring continuous treatment without any extra effort.
• Long-Lasting Use: One cartridge lasts approximately 3 to 4 months under average household use, which equals the effectiveness of about four bottles of traditional septic treatments.
• Easy Installation: Installing the cartridge is straightforward—simply twist the blue cap counterclockwise until the stem pops up, insert and lock it in place, and prime the disposal by running it four times.
• Trusted American Brand: InSinkErator is America’s #1 disposer brand with a reputation built since inventing the garbage disposal in 1927, offering reliable and innovative kitchen solutions.

Pros and Cons

• Pros:
  • Natural enzymatic action reduces buildup and odors
  • Lasts significantly longer than many other septic treatments
  • Simple, no-mess installation
  • Fresh citrus fragrance enhances kitchen hygiene
  • Compatible only with Evolution Septic Assist disposals, ensuring optimal performance
• Cons:
  • Only fits InSinkErator Evolution Septic Assist models
  • Replacement cartridges can be pricier compared to generic enzyme treatments
  • Requires proper disposal of used cartridges

Performance & User Experience

Users report consistent and effective breakdown of food waste, which leads to fewer clogs and reduced odor problems in septic systems. The automatic dispensing feature eliminates the need for manual dosing, making maintenance nearly effortless. The citrus scent is a pleasant bonus, subtly refreshing kitchen air without being overpowering. Installation is quick, even for first-time users, and the cartridge’s lifespan means less frequent replacements, saving time and hassle.

How Does It Compare?

Compared to generic enzyme treatments or liquid additives, the InSinkErator Bio Charge cartridge stands out by integrating seamlessly with compatible disposals and providing a longer-lasting, mess-free solution. While other brands may offer cheaper one-off enzyme packets, they often require more frequent application and don’t deliver the same automatic dosing convenience. This cartridge’s design specifically complements InSinkErator’s technology, ensuring better synergy and performance.

Who Is This Product For?

This cartridge is ideal for homeowners with an InSinkErator Evolution Septic Assist garbage disposal who want a reliable, maintenance-friendly way to enhance their septic system’s efficiency. It’s especially useful for those seeking a natural, enzyme-based treatment that reduces odors and food waste buildup without the need for additional chemicals or manual intervention.
