Spas can be enjoyed alone or with company and have become an inevitable solution for relaxation and well-being today. Although spas are designed for relaxation, untreated water can raise concerns among spa users and completely spoil this moment of relaxation. Fortunately, there are simple ways to maintain a spa and keep its water crystal clear.

Is a Filter Necessary?
Yes, all spas need a filter to properly clean the water. Various contaminants such as body oils, lotions, dirt, impurities, and chemicals that make the spa water cloudy need to be filtered. Spa filters trap these debris, ensuring pure and clear water. Without a filter, spas can have green water, sometimes a vector for disease due to an algae infestation. Unfiltered contaminants can also clog spa pumps, leading to blockages and damage.
The mechanisms of a spa can also be damaged by other contaminants in the water, such as water hardness. Calcium can cause deposits inside a spa filter or heater. To reduce the risk of calcium deposits, maintain the pH of your water between 7.2 and 7.3 and alkalinity between 80 and 90 ppm. A pre-filter removes contaminants that compromise spa water quality, such as metals, calcium, and other sediments. Pre-filters attach directly to a hose and filter water during spa filling.
How a spa filter works
Spa filters eliminate body wastes such as hair, oils, lotions, and dirt from the water. They consist of a plastic core and a filtering medium typically made of polyester. Water circulates through the spa, passes through the filter, and is then reintroduced into the pool. When water passes through a filter, its pleats capture unwanted debris that could damage pumps and cloud the water.
It is necessary to clean them regularly to maintain optimal functionality. Debris can accumulate and clog the filter, making it less and less effective.

Cleaning your spa filter properly
Cleaning your filter regularly is the best thing you can do to take care of your spa. Without proper cleaning, a filter will become saturated and won’t be able to capture contaminants as they pass through. Consequently, the water will quickly become dirty, and you’ll end up soaking in murky water filled with impurities. Maintaining a regular cleaning schedule will ensure that your filter operates as efficiently as possible. Regardless of the quality of your cleaning, it unfortunately cannot last forever. When the filter fibers deteriorate, the filtration quality is compromised. Replacement every 1 to 2 years is recommended, or even sooner if you notice a decline in filtration quality.
The best method for thorough cleaning:
• Weekly rinsing
• Monthly chemical cleaning
• Quarterly chemical soaking
Weekly rinsing
Rinsing the spa filter every week allows clean water to flow freely and ensures that debris does not return to the water.
You can rinse the filter with a garden hose or tap.
Do not use water under too much pressure as it can damage the filter cartridge. You don’t need to use any chemicals in this step, as you are simply rinsing with clear water. While rinsing, separate each pleat of the filter to maximize cleaning. Once rinsed, let it air dry naturally before placing it back.

Monthly chemical cleaning
Chemical spa cleaners are available either with a sprayer or in a regular bottle. We recommend using a sprayer to easily apply the chemical onto the filter. If your cleaner needs to be diluted before use, make sure to add the appropriate amount of water beforehand..
Cleaning your filter monthly is recommended. Spray it generously with your cleaning solution and let it sit for fifteen minutes. After this period, rinse it thoroughly with water, just like you would during the weekly rinse. Let the filter air dry before placing it back into your spa. If chemical residues remain, the water may foam when passing through, requiring draining and refilling the spa. The more thorough your rinsing, the lower the risk of foam formation.
Quarterly chemical soak
A chemical soak is necessary each time you change the water in your spa. If you use your spa regularly, you should change the water every three months. If you don’t use your spa regularly, you should still change the water at least every four months. When changing the water in a spa, you should also clean the interior of the tub. A vacuum designed for this purpose is an excellent way to maintain a clean environment.
To soak the filter, you will need a container large enough to fully submerge the filter and a specifically designed cleaning chemical. Fill the container with the appropriate amount of water and chemical as indicated on the bottle. Let the solution sit for 24 hours. Once the soak is complete, rinse the filter thoroughly with water. Allow the filter to air dry before placing it back into your spa. Residue is more likely to stick to the filter during this soaking process than during rinsing due to the duration. Therefore, take your time, as rushing may cause water foaming and require restarting the spa cleaning process.
What you should absolutely avoid doing
Like many spa owners, you might be tempted to use a homemade chemical cleaner. However, many common cleaners can damage a filter or make the spa water unfit for use.
Household cleaners should never be used to clean a filter. This can lead to foaming issues, no matter how much rinsing is done on the filter.

Bleach is also harmful. Spa filters are made of polyester fibers that do not withstand bleach. Whether diluted or not, bleach will damage your filter, rendering it ineffective in capturing debris in your spa.
Running a filter through the dishwasher will make it unusable. Many guides suggest the dishwasher as an alternative to chemical cleaners, but it’s a bad idea and will cost you more money for a new filter. Also, avoid using water under too much pressure during cleaning; this is why dishwasher usage is not a suitable solution.
In the end, suitable chemicals are specially designed to clean your filter effectively without causing damage. To maximize the lifespan of your filter and keep your spa water clean, you should use a specific spa chemical cleaner and follow the appropriate cleaning instructions.
In a way, you will save money and time.
In summary, a spa filter is essential for maintaining clean and pure water. Make sure to regularly clean your filter by rinsing it weekly, performing a monthly chemical cleaning, and quarterly chemical soaking. Avoid using household cleaners, bleach, or a dishwasher to clean your spa filter, as they can damage it. By following these maintenance tips, you can enjoy your spa for as long as possible while maintaining good water quality.
