If your hot tub water looks cloudy or your jets aren’t performing like they used to, your filter could be the culprit. A clean filter is key to keeping your spa water fresh, safe, and circulating properly. With regular use, debris, body oils, and other gunk can clog your filter. This not only makes it less efficient, but also forces your hot tub to work harder than it should.
The good news? With the right steps, cleaning hot tub filters doesn’t have to be complicated.
This detailed guide walks you through how to clean a hot tub filter thoroughly and keep your spa running at its best.
Why Cleaning Your Hot Tub Filter Matters
Your hot tub filter acts like the lungs of your spa. It’s constantly working to trap dirt, hair, oils, and other contaminants that enter the water. But as it collects more and more grime, it becomes less effective. If neglected for too long, a dirty filter can lead to:
- Poor water quality
- Overworked pumps and heaters
- Higher energy bills
- Shortened lifespan of your equipment
Regular cleaning of spa filters extends the life of your filter and helps maintain balanced water chemistry and crystal-clear water.
How Often Should You Clean Spa Filters?
You can use this guide to clean your spa filter:
- Rinse Weekly: Use a hose to spray off loose debris.
- Deep Clean Monthly: Soak your filter in a hot tub filter cleaner.
- Replace Annually: Depending on usage, replace filters every 12 months or sooner if damaged.
Frequent hot tub use, especially with multiple bathers, or if the spa is used daily, may require more frequent cleanings.
Supplies You’ll Need
Before you begin, gather the following items:
- Garden hose with a spray nozzle
- A bucket or a big container to submerge the filter
- Hot tub filter cleaner (liquid or tablet form)
- Soft brush (optional)
- Clean towel or space for drying
Step-By-Step: How To Clean Hot Tub Filter Like A Pro
Turn Off The Power
Always start by turning off your hot tub to avoid damage to the equipment while the filter is out.
Remove The Filter
Open your hot tub’s access panel and gently pull out the filter. Check for visible signs of wear like tears, discoloration, or a brittle feel. If it looks too far gone, it’s time to replace it.
Rinse The Filter With A Hose
Using a garden hose, spray between each pleat to remove surface debris. This quick rinse helps eliminate leaves, bugs, and larger particles. For better results, use a hose nozzle that delivers a narrow stream to reach deep between the folds. Avoid using a pressure washer, as it’s too powerful, and the pressure can damage the fibers of your filter. This step alone won’t remove oils or lotion buildup, but it’s a necessary prep before soaking.
Soak The Filter In Cleaner
Fill a bucket with warm water and add the right amount of hot tub filter cleaner according to the instructions. Submerge the filter fully and let it soak for a few hours.
Why soak? Because rinsing only gets rid of surface grime. Soaking dissolves oily residues, chemical buildup, and bacteria hiding deep in the pleats. If you use your spa heavily or notice an oily film on the water, consider using a degreasing filter cleaner specifically made for spa filters.
Rinse Again Thoroughly
Rinse the filter well after soaking to remove any leftover dirt and traces of the cleaning solution. Make sure no cleaner remains, as it can cause foaming or water chemistry issues if reintroduced to the tub.
Let The Filter Dry
Let the filter air dry completely before reinstalling. While drying helps prevent mold and mildew growth, it’s not a substitute for proper cleaning and chemical treatment to eliminate bacteria.
If you have a second filter, now is the right time to swap it in. Rotating between two filters gives each one enough time to dry and rest between uses, which helps extend their lifespan.
Reinstall The Filter And Restart Your Hot Tub
Place the clean, dry filter back. Make sure it fits snugly and securely. Turn the power back on and let your hot tub run for a few minutes to make sure everything is working properly.
Tips To Keep Your Filter Cleaner, Longer
- Rinsing off lotions, oils, and deodorants before entering the hot tub reduces the amount of gunk that ends up in the filter.
- Keep the cover on to keep out dirt, leaves, and other things when the tub is not in use.
When To Replace Your Filter
Even with good maintenance, no filter lasts forever. Here’s when to toss it and get a new one:
- Visible tears or damage
- Frayed pleats or fibers
- A bad smell that won’t go away after cleaning
- Water pressure issues or slow circulation after cleaning
If your filter shows any of the above signs, it’s the sign for a replacement. A fresh filter is a small price to pay for clean water and a longer-lasting spa.
Summing It Up
Knowing how to clean a hot tub filter properly can save you money, protect your equipment, and give you cleaner, healthier water. Whether you’re doing a quick rinse or a monthly deep soak with a hot tub filter cleaner, staying on top of filter care is one of the best things you can do for your spa.
It’s easy to overlook, but taking the time to clean spa filters thoroughly keeps everything running smoothly and prevents bigger problems down the line. So grab that hose, mix up your cleaner, and treat your filter to the care it deserves.
