What's Inside Each MXL Filter

  • Icon of a building with water droplets, indicating waterproofing or water resistance.

    Ultra-Fine Sediment Pre-Filter

    Captures rust, sand, silt, and micro-particles as small as 0.01 microns—that’s 100 times finer than standard filters. This first line of defense protects your ionizer’s internal components and ensures the cleanest base water for ionization and mineral retention.

  • Icon of a castle with power lines on top, symbolizing a power plant.

    Premium Activated Carbon Block

    Removes chlorine, chloramines, THMs, VOCs, pesticides, and other harmful chemicals that impact water quality, taste, and odor. This high-density carbon layer delivers crystal-clear, great-tasting water while protecting your body from everyday contaminants.

  • CleanTech™ Metal Reduction Media

    Targets and reduces dangerous metals like lead, mercury, arsenic, cadmium, and chromium, ensuring water meets safe consumption levels. Especially vital for regions with older plumbing, this stage provides peace of mind through advanced heavy metal protection.

  • KDF Process Media

    Remove chlorine and heavy metals. This step extends filter life and keeps your water fresh, clean, and safe for every use.

  • Icon of a water filter with a drop, symbolizing water purification.

    Vitamin C Ceramic Block®

    Infuses your water with Vitamin C to neutralize chloramines and residual chlorine, preventing skin dryness, hair damage, and gut irritation. It’s perfect for sensitive users, promoting healthier hydration from the inside out.

    Mineral Enhancement Stage

    Adds beneficial trace minerals such as calcium and magnesium to boost ionization efficiency and enhance taste. This final stage delivers smoother, more mineral-balanced alkaline water, supporting stronger bones, better metabolism, and optimal hydration.
