Will it fit my hot tub?

Yes if your tub uses an O250 spec cartridge. Most Inflatable Spa, MSpa and plug-and-play tubs do; check existing cartridge dimensions to confirm.

How often do I replace?

Every 4-6 weeks of regular use; sooner under heavy bather load or holiday let turnover.

Can I rinse to extend life?

Yes, weekly rinse keeps the cartridge usable through the 4-6 week cycle. Rinse alone will not extend past 6 weeks.

Single cartridge or 6-pack (~6 month supply for a regular use tub).

Generic or brand-specific?

O250 spec is industry standard; works across all compatible tubs regardless of brand.

How do I clean it between changes?

Rinse weekly with garden hose. Once a month soak in Filter Cartridge Cleaner overnight.

Pleated polyester non-woven, 25 micron rating, 8.5 m² area, integrated polypropylene end caps.

Industry-standard hot tub cartridge spec; defined by 203 mm length, 134 mm diameter, threaded centre mount.

Can I bleach it to extend life?

No. Bleach degrades polyester pleats and shortens life. Use only Filter Cartridge Cleaner or equivalent.

Cloudy water with new cartridge?

Sanitiser too low or shock needed; not filter problem.

Replace and lubricate before refit.

Polyester vs paper cartridge?

Polyester pleats wash and last longer; paper is single-use. Polyester is the modern hot tub standard.
