The Essential Guide to Replacing Your Spa Filter Cartridges

Maintaining a pristine and healthy spa environment is not just about keeping the water chemically balanced; it's also about ensuring your spa's filter cartridges are in top condition. This guide will provide you with the knowledge and confidence to assess when your spa filter needs replacing and how to select and install the correct replacement cartridge.

Understanding the Role of Spa Filters

Spa filters are crucial in maintaining the cleanliness and clarity of your spa water. They trap debris, dirt, and other particles, playing a pivotal role in providing a safe and enjoyable spa experience.

Types of Spa Filters

  • Pleated Filters: These are common and effective at trapping particles larger than 20 microns.
  • Micron/Purezone Filters: Designed to capture smaller particles down to 5 microns, these filters reduce the need for additional chemicals.

When to Replace Your Spa Filter Cartridges

Regular inspection and timely replacement of spa filter cartridges are essential. Indicators that your filter needs replacement include a cracked end cap, deteriorating water quality, or visible damage. Pleated filters generally last 12-18 months, while micron filters should be replaced every 3-6 months, depending on usage.

Steps to Replace Your Spa Filter Cartridges

1. Removing the Cartridge Filters:

  • Open the skimmer of your spa.
  • Grasp the handle of the cartridge filter.
  • Gently turn and unthread the filter for removal.

2. Assessing the Need for Replacement:

  • Examine the filter for wear or damage.
  • Look for cracks, poor water quality indicators, or visible wear.

3. Choosing the Right Replacement Filter:

  • Measure the outside diameter and overall length of the cartridge, including end caps but excluding handles or strings.
  • For a more accurate measurement, measure through the center of the cartridge when possible.
  • Note the inside diameter of the opening if the top and/or bottom is open.
  • Identify any unique features of the end cap (e.g., handles, threads, knobs).
  • Record the manufacturer (OEM) and model number of the filter.
  • Count the number of pleats and note the presence of a center cone.
  • Types of ends to identify include Open, Closed, Semi-circle handle, Thread, Female thread, Injection moulded knob handle, Open cross castle, Male slip fitting, Injection moulded cone adapter, Twist lock bayonet.

4. Installing the New Filter:

  • Carefully thread the new filter into place, ensuring it's securely fitted but not over-tightened.
