Refresh and protect your water at home with a four-pack of M3005 filters

The Frizzlife M3005 replacement filter cartridge set is built to refresh SP99 and SK99 under-sink filtration systems. Featuring a 0.5 micron purification stage, this advanced filtration helps reduce common impurities while preserving minerals that contribute to water’s body and flavor. This four-pack is compatible with SP99, SK99, SP99 NEW, and SK99 NEW models, making it easy to keep your filtration performance consistent with minimal downtime.

What you get and how it helps

Each cartridge works in concert to target different particle sizes, delivering cleaner water at the tap. The 0.5 micron stage offers refined filtration that can lessen chlorine taste and odor and small particulates. The result can be water that tastes crisper and feels smoother, without sacrificing beneficial minerals that contribute to overall mouthfeel.

• Compatible replacement filters for Frizzlife SP99 SK99 and their NEW variants
• High filtration performance with 0.5 micron accuracy
• Reduction of lead, chlorine, tastes and odors, and particulates

Long-lasting, cost-effective filtering

Replacing the cartridges is designed to be affordable compared to buying bottled water. The twist-in design makes swaps quick and toolbox-free with the included housing wrench, so you can maintain your system with minimal downtime.

• Twist-in operation for fast, tool-free replacements
• No additional tools required beyond the included housing wrench
• Ongoing savings versus bottled water delivery

Maintenance guidance for steady performance

To keep filtration performing as intended, follow the recommended replacement schedule. Change the sediment filter every 3–6 months, the 3–5 micron CTO every 8–12 months, and the 0.5 micron CTO every 12–18 months. Actual longevity varies with water quality and daily usage.

Why choose the Frizzlife M3005 four-pack

Having a four-pack on hand supports continuous filtration without frequent shopping trips. The combination of high filtration precision, broad compatibility with key SP99 SK99 models, and a simple replacement process makes it a practical option for households seeking reliable, at‑home water filtration.
