Relxtime Blue Filter Cartridge Replacement 6 Pack

You fill your RELXTIME spa, the water’s warm, the jets are going — and the last thing you want to think about is maintenance. But here’s the honest truth: a dirty or worn-out filter is the fastest way to ruin that experience. The water goes cloudy, the pump works harder than it should, and suddenly relaxing doesn’t feel so relaxing. That’s exactly why keeping a good supply of replacement cartridges on hand actually matters. The Relxtime 6 Pack Hot Tub Filter Cartridge Replacement is a straightforward solution to a real, everyday problem. Six quality filters, built specifically for RELXTIME spas, ready to rotate in whenever your current one needs a break.

What Makes These Filters Different?

A lot of replacement cartridges on the market use basic filter paper that does an okay job — but just okay. These use premium blue filter paper that genuinely outperforms the standard stuff. You’ll notice it in the clarity of the water after the first few uses.

The dacron fiber pleats are the other thing worth mentioning. Pleated filters have more surface area than flat media, which means more water gets properly filtered with every pump cycle. They’re also more durable — they hold their shape after repeated rinse-and-reuse cycles instead of breaking down after a week.

Together, these two materials catch what actually ends up in your spa water: hair, leaves, dust, fine sediment, and other particles you’d rather not soak in.

Designed to Fit Every RELXTIME Spa Pool

Compatibility matters, and these cartridges are built with that in mind. They fit all RELXTIME spa pools — no guessing, no sizing charts, no returns because the dimensions were slightly off.

Those dimensions aren’t approximate — they’re exact. The filter seats properly in your water inlet and stays there until you decide to pull it out.

Cleaning and Replacing Takes Two Minutes

This is genuinely one of the easier parts of spa ownership. Here’s the full process:

• Pull the filter out of the water inlet inside your spa
• Detach the cartridge from the housing
• Rinse it with a garden hose — run water through the pleats from top to bottom
• Reinstall it or drop in a fresh one from your pack

That’s it. Most people rinse their filter every 1–2 days during regular use. If you’re using the spa daily, have guests over often, or running longer sessions, bump that up to a replacement every 2–3 days. With six in the pack, you’ve got a proper rotation going without reordering every couple of weeks.

Reusable — But Know When to Replace

These filters are designed to be rinsed and reused — and with proper care, each one holds up through multiple cleaning cycles. The important thing is knowing when a cartridge has reached the end of its life. If you rinse it thoroughly and the water still doesn’t clear up the way it should, it’s time to pull that one out and move on to the next.

Think of it this way: a clean filter protects your pump. Your pump is the most expensive part of your spa setup. Replacing a $3 filter cartridge on schedule is a lot smarter than dealing with a pump that’s been struggling against a clogged one for two weeks straight.

The Right Buy for RELXTIME Spa Owners Across Canada

Whether you’re using your spa through a Canadian summer or keeping it running into the cooler months, consistent filtration is what keeps the water safe and enjoyable. This 6-pack is a practical buy — enough supply to maintain a proper replacement schedule without overstocking.
