DIY Hot Tub Filter Cleaning | Keep Your Spa Pristine in 5 Simple Steps

You’re ready to unwind after a long day, but your hot tub’s jets sound like a broken vacuum. What’s the deal? Your filter’s packed with gunk—lotions, leaves, and leftover sunscreen. The fix? A quick clean with stuff you already own. No fancy tools or repair calls needed. Regular diy hot tub filter cleaning not only keeps your water sparkling, it also helps extend the life of your spa. Let’s turn that murky mess into a bubbly retreat.

Why Clean Your Filter?

Think of your filter like a coffee filter. If it’s clogged, your brew (or spa) gets gross. A dirty filter strains your pump, hikes bills, and turns water cloudy. Clean it regularly to keep things running smooth and save cash.

How often should you clean it? If you use your tub weekly, aim for a rinse every 2–4 weeks and a deep clean every 3–4 months. But if your backyard doubles as a pollen battlefield or your kids treat the tub like a snack-friendly pool, you’ll want to step up that schedule.

What You’ll Need

Grab these tools (most are probably in your garage already):

  • Garden hose (with a spray nozzle)
  • Filter cleaner solution (like SpaGuard Filter Cleaner)
  • Soft-bristle brush (an old toothbrush works for tight spots)
  • Bucket (for soaking)
  • White vinegar (for mineral buildup)
  • Latex gloves (optional, but grime happens)

Step 1: Pull the Filter—Without the Panic

Shut off the tub’s power (safety first!). Locate the filter compartment—usually under a lid near the center. Twist the filter counterclockwise and lift it out. If it’s stuck, a dab of lubricant on the O-ring next time will help.

Pro tip: Snap a photo of the filter’s position before removing it. Trust me, you don’t want the “how does this thing go back?!” headache later.

Step 2: Blast Away the Gunk

Take the filter outside and use your hose’s jet setting to spray down the pleats, starting at the top. Imagine you’re pressure-washing a greasy baking sheet—angle the spray to force debris out, not deeper in. Avoid high-pressure washers; they can shred the material.

See a chalky white crust? That’s calcium buildup. Soak the filter in a 50/50 water-vinegar mix for an hour, then gently scrub with your brush.

Step 3: Soak for a Deep Clean

Every few months, give your filter a spa treatment. Fill a bucket with warm water and add filter cleaner per the instructions. Let it soak overnight to break down oils and biofilm.

Fun fact: That slimy film? It’s called biofilm, and it’s basically a bacteria condo. The EPA recommends regular filter maintenance to prevent it from taking over.

Step 4: Dry Thoroughly (Yes, Really)

Shake off excess water and let the filter air-dry in the shade. Sunlight can weaken the material over time. Once it’s dry, give it a quick visual check. Frayed pleats or cracks? Time to replace it—most last 1–2 years.

Step 5: Reinstall and Repeat

Slide the filter back into place, twist clockwise, and power up the tub. Check for leaks, then pat yourself on the back. You’ve just saved $100+ on a service call!

Maintenance hack: Keep a spare filter on hand. Rotate them each cleaning cycle to extend their lifespan.

Common Mistakes to Avoid

  • Using dish soap: It leaves residues that foam up your water.
  • Skipping the soak: Rinsing alone won’t kill bacteria.
  • Overcleaning: Too-frequent deep cleans can wear out filters faster.

When to Call a Pro

If your tub’s pressure gauge stays high after cleaning, or water flow’s weak, you might have a pump issue. Book a technician—and pair your clean filter with weekly water testing (those test strips are lifesavers) to keep chemicals balanced.

Final Thought

Cleaning your filter is like brushing your teeth—annoying but necessary. A little effort keeps your spa ready for relaxation. Now go enjoy those bubbles (and brag about your DIY skills).
