2 Pack Hot Tub Filter Cartridge with Protective Cover

There’s nothing worse than settling into your hot tub after a long Canadian winter day, only to find the water looking cloudy or smelling off. That’s almost always a filter problem. The Relxtime 2 Pack Hot Tub Filter Cartridge is the straightforward fix — two replacement filters built specifically for Relxtime inflatable spas, so your water stays clear and your soaks stay relaxing.

Why the Filter Cartridge Matters More Than People Think?

Most hot tub owners don’t think about their filter until something goes wrong. By then, the pump’s already working harder than it should, and the water chemistry is off balance. A fresh Relxtime replacement filter cartridge takes maybe two minutes to swap in — and it makes a real difference you’ll notice the same day.

These filters use premium blue filter paper paired with dacron fiber pleats, which together trap the fine stuff that regular filters miss: hair strands, leaf fragments, fine dust, and sediment. The result is water that actually looks and feels clean, not just warm.

How to Clean and Replace Your Relxtime Filter Cartridge?

It’s a simple process, and once you’ve done it once, it takes no time at all:

1. Locate the water inlet inside your Relxtime spa.
2. Remove the filter housing and slide out the used cartridge.
3. Rinse the cartridge thoroughly with a garden hose — work from the inside out.
4. Let it dry briefly, then reinstall it. Or drop in the second cartridge while the first one dries fully.
5. Under lighter use, a weekly change is enough. During heavy summer use or after parties, switch it every 2–3 days.

One honest thing to keep in mind: rinsing extends filter life, but it doesn’t last forever. The dacron fiber pleats will eventually wear down after repeated cleaning cycles. Keeping a 2-pack on hand — or ordering a second pack — means you’re never caught without a clean filter when you need one.

Who This Filter Is For?

• Regular Relxtime spa owners who want to stay on top of routine maintenance without overspending.
• Heavy users who run their spa several times a week and need fresh filters more often.
• Canadian spa owners dealing with cooler temperatures and seasonal debris — leaves, pine needles, and outdoor dust all get caught in your filter faster than you’d think.
• Anyone who’s noticed their spa water getting murky and wants the quickest fix possible.

The Relxtime Difference

Relxtime designs these cartridges to fit their own spa range perfectly — no awkward sizing, no guessing whether it’ll thread in correctly. The 100mm outer diameter and 60mm inner diameter match the water inlet on all Relxtime models exactly. You won’t be forcing a generic filter into a space it wasn’t made for.

A clean filter also takes the load off your spa’s pump. When the filter is clogged, the pump works harder, uses more energy, and wears out faster. Staying on schedule with your Relxtime 2 pack filter cartridge replacement is one of the easiest ways to extend the life of your whole spa system.
