ZOTEE Pool Filter Cartridges – Inner & Outer Set for Sta-Rite 25021-0200S/25022-0201S (S7M120)

Upgrade your pool filtration with the ZOTEE Pool Filter Cartridges Inner & Outer Set, designed to replace Sta-Rite components in System 3 configurations. This complete cartridge pair blends durable materials with a high-capacity design to help keep your water clear and inviting through the season. While results can vary with pool size, climate, and usage, many pool owners notice easier maintenance and steadier flow when using quality replacements like this set.

What’s Included and How It Works

• Inner filter: outer diameter 8-3/4", length 25-1/4"; filtration area around 100 sq. ft.
• Outer filter: outer diameter 16-1/2", length 18-3/4"; filtration area around 200 sq. ft.

This pairing is built to mirror the filtration footprint of Sta-Rite’s System 3 S7M120, offering a straightforward swap for compatible setups. Expect efficient water flow and a substantial filtration surface to capture particulates as you swim or treat the pool.

Durability and Filtration Performance

• Reinforced structure with thick trilobal fabric for robust use and chlorine resistance
• Heavy-duty end caps and reinforced center support help maintain shape under pressure
• Advanced pleated design increases surface area, improving debris capture from hair and leaves to dust and sediment

The combination of sturdy materials and a high-pleat count aims to deliver continuous filtration power, helping your pool water stay crisp and clear between cleanings. While not a guarantee of never requiring maintenance, the design supports consistent performance over time.

Maintenance and Practical Use

• Easy to clean: trilobal fabric releases impurities during rinsing, simplifying periodic upkeep
• Recommended maintenance cadence: consider cleaning every two weeks to help preserve flow and efficacy

In real-world use, this set can be a practical upgrade when you’re restoring filtration capacity after seasonal shutdowns, or when you want to refresh a tired system. It supports smooth, predictable operation that many pool owners appreciate for weekend swims and family gatherings alike.

Overall, ZOTEE’s inner and outer cartridge set offers a balanced mix of compatibility, durability, and filtration capacity. It’s a thoughtful option for those who value clear water, manageable upkeep, and a straightforward replacement path for Sta-Rite System 3 configurations.
