Picture-perfect hot tub water is clean and clear, with just the slightest hint of a blue hue. It’s inviting, rejuvenating, and sets the stage for ultimate relaxation. But the secret to achieving and maintaining that water quality isn’t just about adding chemicals — it starts with proper filtration.
As a hot tub owner, cleaning your hot tub filters is one of the most important things you do to keep the water looking its best. Filters are designed to trap dirt, debris, and other contaminants that you don’t want in the water. However, they can only trap so much dirt before it affects performance. Over time, filters become clogged with oils, lotions, and other particles, reducing their efficiency and potentially compromising your water quality.
Cleaning your hot tub filters on a regular basis not only ensures they work at peak performance, but also extends their lifespan — saving you money and maintaining that crystal-clear water you love.
From understanding how to deep clean to buying replacements, these tips will help you become a pro at cleaning your hot tub filters.
Why clean hot tub filters?
Your hot tub’s filter is a key player in keeping your spa water clean and your equipment running smoothly. It traps a wide variety of contaminants, from leaves and hair you can see to tiny particles and oils you can’t.
The main part is made of pleated, white fabric. Think of this material as a super-fine net that lets water pass through but catches unwanted bits. As water moves through the filter’s folds, it leaves behind debris, keeping your spa water clean.
At each end of the filter, you’ll find plastic caps. These caps do two things: they hold everything together and allow the filter to attach securely to your hot tub.
Master Spas hot tub filters also incorporate an EcoPur Charge core. Secured into the center of your filter, this core releases natural minerals including zinc and copper to clean your water. It also helps reduce heavy metals in the water and controls scale, bacteria, and algae.
Depending on the size of your hot tub, you might have one or two filters. As the filter does its job, it accumulates all the debris it’s been catching and becomes less effective. Dirty filters can negatively impact the quality of your components and even damage your hot tub’s components. Regular cleaning ensures your hot tub runs efficiently and extends the life of the filter.
When should you clean your hot tub filters?
Filter care is a part of any hot tub maintenance routine, just like testing the water and balancing chemicals.
But how often should you clean your hot tub filters?
There are a number of factors that can affect how often you need to clean your filters, including how often you use your hot tub and how many people hop in. As a general rule, though, you should rinse your filters once a week, as it helps remove surface debris such as leaves and pollen.
Master Spas also recommends using a filter cleaner once a month to break down oils and minerals. Traditional filter cleaners require you to soak the filter overnight, rinsing them in the morning. You can also use spray filter cleaners that minimize the cleaning time.
When your hot tub filter begins to show wear and tear, it’s time to replace it. Signs that you need to replace your filter include flat or misshapen pleats and discoloration, even after a thorough cleaning. You can expect to replace the EcoPur Charge core every six months. With proper care, hot tub filters can last a year.
How to clean your hot tub filters
Maintaining your hot tub and the water goes hand in hand with regular filter care. By consistently cleaning your spa’s filters, you’re not just keeping the water clean and clear – you’re also investing in the longevity of your hot tub.
But how do you clean your hot tub filters?
The process starts with turning off the power to your hot tub. This prevents any accidental activation of the system while you’re working on it.
Then, locate your hot tub filter. It is in a specially designed compartment for easy access and maintenance. Twist it out carefully, following the directions in your owner’s manual.
Once removed, you can use a garden hose with a spray nozzle to rinse the filters thoroughly. Start at the top and work your way down, making sure to remove any visible debris. You can also use a hose attachment designed to clean filters. The design of the nozzle allows you to spray water between the pleats, removing any dirt or debris that is closer to the core. Be gentle to avoid damaging the filter elements.
For a deeper clean, soak the filters in a filter-cleaning solution available at your local Master Spas retailer. Follow the instructions on the package for the correct proportions and soaking time. This step helps to dissolve stubborn oils and minerals that a simple rinse might miss. Just a quick note: There’s no need to soak the EcoPur core — it can deactivate the minerals.
After soaking the filters, rinse them thoroughly with clean water to remove any remaining cleaning solution or debris. It’s important to ensure no residue is left behind, as it can affect the quality of your hot tub water.
Once the filters are clean, reinstall them into the filter compartment. Make sure they are securely in place before turning the power back on.
Common questions about how to clean hot tub filters
How do you clean hot tub filters without chemicals?
While some hot tub owners opt for natural cleaning solutions made with vinegar, specialized cleaners are most effective.
Can I use a pressure washer to clean my hot tub filter?
Pressure washers are not recommended, as the high pressure can damage the delicate filter fibers. Stick to a standard garden hose for best results.
How often should I replace my hot tub filter?
Generally, every 12 months, but this can vary based on usage and care. Having a second set of filters and alternating between the two sets can also extend the lifespan. It’s important to replace your filter if you discover damage or notice that your water isn’t as clean and clear as you’d like, even with the water balanced.
Can I clean my hot tub filter in the dishwasher?
Putting your hot tub filter might seem like a good idea. The sprayer might be able to get between the pleats of the fabric, and it keeps your hands free to do other chores. However, it’s not recommended. The high heat and harsh detergents can damage the filter and leave residue that affects water chemistry.
Do you have any tips for extending the life of my hot tub filter?
Absolutely! There are several ways to prolong your filter’s lifespan. First and foremost, it’s important to maintain proper water chemistry. When your water is balanced and chemicals are in range, it puts less stress on your filter. Always shower before using your hot tub to reduce the amount of oils, lotions, and debris entering the water. When filling your spa, use a pre-filter that attaches to your garden hose to remove impurities. Keep the area around your hot tub clean to minimize debris that can enter the water. Lastly, try floating a few tennis balls in your spa – they can help absorb oils and lotions from the water’s surface.
What happens if I don’t clean my hot tub filter?
Neglecting filter maintenance can lead to poor water quality, increased chemical usage, strain on your spa’s systems, and potentially costly repairs.
How can I keep up my maintenance routine in the winter?
Maintaining your hot tub filters is a year-round task, but winter brings a unique set of challenges. To clean your filters effectively during colder months, choose a milder winter day if possible, and set up an indoor cleaning area in your garage, basement, or utility room. This protects both you and the filters from freezing temperatures. Use rubber gloves to keep your hands warm and dry during cleaning, and work quickly when reinstalling to minimize exposure to cold air.
By taking these simple steps to clean your hot tub filters, you’ll ensure your spa remains a haven of relaxation and enjoyment.
