What better way to relax than by soaking in a hot tub at the end of the day? Not only is it a great way to relieve stress but the massaging action of the jets can also help relax and soothe tense, tight muscles.
In doing so, it can help relieve some types of pain. For example, it can help those with arthritis and fibromyalgia.
Given that, it’s easy to see why hot tubs are so popular. In the U.S. alone, there are nearly 6 million of them – which isn’t surprising, seeing as how they last decades.
But let’s face it, going to the swimming pool every time just for the hot tub isn’t very convenient. That’s why some people choose to buy one for their homes instead.
While they’re not exactly cheap, they can be a worthwhile investment for those who use them regularly. It’s also a great way to spend time with family and friends.
The only thing is that you do have to maintain them regularly – that means sanitizing the tub weekly and draining and flushing the entire thing three to four times a year.
That’s not all, the filter also needs to be cleaned every month. That way, you won’t have to worry about the water quality causing clogs. For example, algae, bacteria, and other pollutants can build up on the surface and make their way to the filter.
And if that happens, your hot tub pump will have to work harder to pull water through, and over time, that can cause irreversible damage. That’s why it’s so important to keep up with your cleaning schedule.
In terms of how to clean them, it’s best to use a commercial hot tub filter cleaner – they’re specifically formulated to increase the efficiency and lifespan of your filter.

Easy to use, the fast-acting formula is capable of removing suntan, dirt, grease, scale, and other contaminants from the filter. Suitable for hot tubs, home spas, and pools.

Hot Tub Filter Cleaners – Q&A
What is the best thing to clean hot tub filters with?
It's best to use a commercial hot tub filter cleaning product. While DIY options such as vinegar may help remove some deposits, they won't be enough to remove all contaminants from the filter. Commercial products, on the other hand, will effectively loosen grease and oils so that you can easily wash and rinse them away with a hose.
How often do you need to soak a hot tub filter?
Ideally, you want to soak and clean the filter in a cleaning solution every one to two months- when you're changing the water for the hot tub. Never use dishwater detergent, bleach, or other household cleaners. Depending on how often you're using the spa, however, you may want to rinse your filters once a week to prevent residue from building up.
What happens if you don’t clean your hot tub filter?
Over time, sediment and other debris can clog the filters if they're not cleaned properly. That will decrease water flow, which will make it more difficult for water to pump through the filter. Not only that but chemicals can also accumulate and eat away at the filter material. That's why it's so important to keep up with your cleaning schedule.
Why is my hot tub filter turning brown?
Metals in the water such as iron can stain the filter over time, giving them a light brown appearance. In some cases, it may also appear yellow, green, gray, or purple. Fortunately, the presence of metals doesn't affect the filter's performance, or the length of time between cleanings.
Do you need to pre soak hot tub filters?
Unless you're using a non-rinse cleaner, it's highly recommended that you soak the filter for a few hours. Just make sure to rinse it thoroughly with water afterward, otherwise you'll get excessive foaming.
Can I soak my hot tub filter in chlorine?
No, harsh chemicals such as chlorine and bleach should never be used to clean hot tub filters. They can easily damage the filter media and reduce its lifespan. Household cleaners should also be avoided as that can cause significant foaming.
Why does my hot tub filter keep clogging?
Hot tub filters can easily clog with dirt and other debris. If left alone, they can cause the filter to stop working entirely and that can lead to bad odors, cloudy water, and even skin irritation.
How often do you need to change a hot tub filter?
It's highly recommended that you replace the hot tub filter once a year. Some higher-quality products, however, can be used for up to two to thee years, depending on how often the spa is used. Low-quality filters, however, generally need to be replaced much sooner.
