Hot Tub Filters 101

Your hot tub filters help ensure your hot tub's overall performance and long life. They work in the background, trapping particles and debris as water runs through the filter media and acting as the 1st line of defence dirty spa water.


To put it simply, all the water in the hot tub passes through the filters trapping unwanted particles in their folds.

Most of today's hot tub filters today are designed as cartridges that can be easily removed, cleaned, and replaced and consist a core structure—usually plastic—and a pleated medium wrapped around the core that acts as the filter. These "pleats" or folds work by greatly increasing the surface area of the filter for better cleaning action. The greater the filter surface area, the cleaner your water will be.

The particles trapped by the filters remain until they're cleaned out, so your role in maintaining the filter contributes greatly to its effectiveness. Neglecting regular filter maintenance places undue strain on the water pumps and heating systems and cause dirt and grime to build up.


Keeping your filters clean and replacing them when necessary are the keys to optimal hot tub health, performance, and long life. Luckily, today's advanced cartridges are easy to clean, making your part in hot tub filter maintenance a straightforward matter.

Filter maintenance and replacement schedules will vary depending on how often you use your hot tub and how many people regularly soak in it. The more contaminants that are introduced into the water, the more buildup the filter will collect. When the filtration medium is compromised, so is its ability to hold a strong line of defense against dirty spa water. To keep your hot tub running efficiently, consider calendaring your inspections, monthly cleanings, deep cleanings, and spa-drainage days according to usage over a 12-month period.

Every time you remove your filters for cleaning, be sure to also inspect them for signs of wear, tear, or cracking. Pay extra attention as cartridges grow closer to the end of their lifespans. When it's time to replace your filters, choose only the certified, branded filters designed for use with your hot tub model. When your home spa depends so heavily on maximum filtration power for overall performance, you want to rely on the best.

Monthly Maintenance

Rinse with a garden hose or under a tap and inspect the filter for signs of wear and tear. Using an instant filter cleaner spray can also help to break up oils and other stubborn particles.

Deep Cleaning

Soak the filters in filter cleaning solution for the length of time recommended then allow to dry naturally.


Replace every 1-2 years, depending on usage and visible wear & tear

We recommend rotating between two sets of filters to achieve maximum filter life and ultimate clean water.
