Guide To Hot Tub Filters

There’s no denying that hot tubs are great for relaxing. However, a hot tub requires regular

attention and upkeep, to ensure they are safe for use. Hot tub filters are no exception.

There are many types of hot tub filters to choose from, but they all do require periodic cleaning

and maintenance. Thankfully, cleaning hot tub filters is an easy job anyone can do! With this in

mind, here’s our guide to maintaining your hot tub filters.

Types of Hot Tub Filters

There are four types of hot tub filters currently on the market. It’s important you choose the

correct one to avoid any issues with your spa. These include:

Cartridge Filters

These are the most popular choices of filter for hot tub owners. Cartridge

filters a cylinder shaped unit that is typically crafted of paper, fabric or plastic. These can simply

slide inside the filter housing space inside the spa and used up to a year with regular cleaning.

Ceramic Filters

These are similar to cartridge filters, but are built with a resilient ceramic that

generally outlives all other types of filters. Ceramic filters can last for several years before

requiring replacement, provided they are regularly maintained.

Sand Filters:

Sand filters are typically spherical containers filled with sand and gravel that pulls

out unwanted substances when water passes through. They commonly sit outside of the hot tub

and require frequent cleaning with a particular type of sand.

Diatomaceous Earth Filters

If you’re looking for an eco friendly hot tub filter, the diatomaceous earth filters is the one for you. These use fossilised diatoms in lieu of activated carbon. However, they work just like cartridge filters and collect unwanted debris from the spa water.

While we don’t currently have diatomaceous earth filters in stock, we do have a range of eco

friendly hot tub filters that not only protect the environment, but are much more reusable than

the typical cartridge filters. Check out our range of EGO3 Filters today

How To Clean A Hot Tub Filter

The best way to ensure good water quality and increase the longevity of your hot tub is to

regularly clean your hot tub filters. We recommend using a hot tub filter cleaner such as Spa

Marvel Filter Cleanser to ensure your filters are clean and operating at their full potential.

Keeping your filters clean is much easier than you think. If you’re wondering how to clean hot

tub filters, here are our recommended cleaning methods for cartridge-style hot tub filters.

  • Weekly Quick Rinse—Remove the hot tub filter once a week and give it a good rinse with fresh water. Make sure to take the time to spread out the pleats and remove any debris or residue. Rinse the filter again, and allow it to air dry before replacing it into the tub.

  • Monthly Chemical Rinse—Once per month, remove the filter and generously spray it down with a hot tub filter cleaner. We recommend using the Yourspa Filter Cleaner and submerge the filter in a bucket of water and solution. Allow the solution to sit for 15 minutes or as directed on the cleaner. Thoroughly rinse and replace into the spa unit.

When To Change Your Hot Tub Filter

As a supplier of the best hot tub chemicals and hot tub filter replacements, Aqua Spa Supplies

recommends changing hot tub filters once a year. Unless your spa uses ceramic cartridges,

which can last for several years.

If the cartridge becomes damaged in any way such as bent or ripped media or brittle end caps,

it’s essential to replace the unit right away. If you are looking hot a replacement hot tub filter,
