Frequently Asked Questions

Is this a genuine Paramount or Theralux cartridge?
No — this is a high-quality generic replacement cartridge manufactured to the same dimensions and performance standard as the OEM part #701038. It is a direct drop-in replacement requiring no modifications.

How do I know this cartridge fits my filter?
Confirm compatibility by matching the dimensions: 260mm diameter × 440mm length × 75mm centre hole with open ends. This cartridge replaces OEM part #701038 and suits Paramount Opal 180, Theralux Filter Pro 180, and Theraclear 180 filter housings.

How often should I replace my filter cartridge?
Typically every 2–3 seasons, or when the cartridge no longer returns to clean operating pressure after washing. Regular rinsing and periodic deep-cleaning with cartridge cleaner solution will extend service life.

How do I clean this cartridge?
Rinse from top to bottom with a garden hose at low pressure. For a deeper clean, soak in diluted cartridge cleaning solution for several hours, rinse thoroughly, and allow to dry before refitting. Avoid pressure washing as it damages the trilobal pleats.

What is trilobal filtration material?
Trilobal (three-lobed) fibre has a larger surface area than standard round fibre, which increases dirt-holding capacity and filtration efficiency. It captures finer particles while maintaining good flow rates through the filter.
