Mix Box 20"x4.5'' Water Filter System Set Compatible with Big Blue(4PCs)

Protects Appliances: Safeguards your water heater, dishwasher, washing machine, and plumbing fixtures from sediment buildup.

Keep every drop of your household water pure and refreshing with the 20" Complete 3-Stage Replacement Filter Set. Engineered for standard 20-inch filter housings (4.5" diameter), this premium set combines three high-performance cartridges - a sediment filter, a granular activated carbon (GAC) filter, and a carbon block filter - to target a full spectrum of contaminants.

Why three different filters?

Each layer has a specific job. The first stage, a 1-micron melt-blown sediment filter, acts as a sturdy barrier against visible particles like dirt, rust, and sand. It traps large volumes of debris without clogging quickly, so you get consistent flow and fewer mid-cycle changes.

The second stage uses granular activated carbon (GAC) - carbon that has been oxygen-treated and broken into small granules to maximize surface area. As water flows through the GAC bed, chlorine, volatile organic compounds (VOCs), and other chemical impurities bond to the carbon molecules. This dramatically improves taste and odor while removing common tap water chemicals like pesticides and industrial solvents.

The third stage is a carbon block filter. Made from finely ground activated carbon compressed into a solid block, this dense filter polishes what the GAC started. It captures any remaining fine particles and provides extra chlorine reduction, ensuring your water tastes clean, bright, and free of any aftertaste.

Smart two-carbon design - By using both GAC and carbon block in the same system, you get the best of both worlds: the high adsorption speed of granular carbon plus the fine particle-trapping precision of a solid block. The result is consistently better water for drinking, cooking, coffee, and ice making.

Installation & Maintenance - All three filters are standard size (20" long, 4.5" outer diameter) and fit most popular 3-stage slimline housings. Replacement is a straightforward DIY task - no need to call a professional. For optimal performance, change the entire set every 3 to 6 months. Heavier sediment or high chlorine levels may require more frequent changes. Regular replacement not only gives you better water but also protects your housing and any downstream equipment from premature wear.
