When it comes to finding the right filter model, we've got you covered. If you already know your filter's part number, simply check if it is listed below. Alternatively, if you know the brand of your cartridge, you can refer to the compatible models provided.

Please note that the information about manufacturers' names and part numbers is solely for compatibility purposes, and the respective holders retain ownership.

The key features of our filter cartridges include:

1. Sturdy ABS plastic frame that is resistant to melting or cracking.
2. Extra pleats for maximum filtration efficiency, ensuring a sparkling clean pool.
3. Strong triangular plastic frame that firmly supports the filter layer and prevents it from breaking.
4. Easy cleaning - simply rinse the filter every 4-6 weeks for optimal performance, allowing these filters to last 2-3 years with proper use.
5. Plug-and-play installation - just open the cap and replace the cartridge.

It's important to note that the filter has a specific front and back orientation, and installing it the wrong way can damage the filter.

When should you replace your filter cartridges? Here are the key indicators:

1. High water pressure: If the running pressure of your pool filtration system starts to climb and doesn't come down after a thorough cleaning, it's time to replace the cartridge.
2. Cracked frame: If the frame of your cartridge has become brittle and cracked or chipped, it should be replaced immediately to prevent damage to your system.
3. Torn pleats: If the fabric of the pleats is torn or has a fuzzy appearance, the effectiveness of the cartridge has been compromised, and it should be replaced.

Our 4-pack replacement filters are compatible with popular robotic pool cleaner models, including Dolphin M200, M400, M500; Nautilus CC Plus (not for Nautilus CC or Nautilus Pro); Oasis Z5i, Sigma, C3, C4, Triton Plus (old), and Aquarius XL. The dimensions are the same as the original filters, providing a perfect fit.

With their powerful filtration capabilities, premium quality, and reusability, our filter cartridges offer exceptional value and convenience, allowing you to enjoy a sparkling clean pool with minimal maintenance.
