Spas used heavily or by multiple people may need more frequent replacement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I clean this filter instead of replacing it?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Regular rinsing and monthly chemical soaking extends cartridge life significantly. However, once the pleated media shows physical damage, persistent discolouration, or your water clarity doesn't improve after cleaning, it's time to replace.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Should I keep a spare filter?\u003c\/strong\u003e\u003cbr\u003eA: Yes, and it's one of the best things you can do for your spa. Rotating between two cartridges means one is always clean and dry, ready to go in while the other soaks or dries. It also extends the life of both filters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What's the difference between a Freeflow 46 and other spa filters?\u003c\/strong\u003e\u003cbr\u003eA: The \"46\" refers to the filter area in square feet. Different spa models require different filter sizes and configurations. The 225 x 135mm dimension is the physical size of this cartridge. Always match both the dimensions and the end cap configuration to your existing filter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this in stock?\u003c\/strong\u003e\u003cbr\u003eA: Stock levels are shown live on this page.
