GW Multi-Round Filter Replacement Pack – Aquametix or KDF55

This replacement pack is designed for the legacy GW Multi-Round systems (GW4, GW5, GW7, and GW9).
Choose between two high-quality filter options to match your water needs.

Filter Options:

• Aquametix – Broad-spectrum performance with effective fluoride reduction, plus many other contaminants.
• KDF55 – Excellent for chlorine, heavy metals, and other common contaminants. Note: KDF55 does not reduce fluoride.

Choosing the Right Filter:

If you are concerned about fluoride, select one of the GW options (Aquametix).
If fluoride is not a concern, you may choose one of the KDF options.

Note: The numbers (4, 5, 7, 9) refer to the number of filters included in your Multi-Round system. Please select the option that matches your system from the dropdown menu before adding to cart.
