How Do You Clean Hot Tub Filters?


Most new hot tub owners are aware that regular cleaning of their spa’s filter is necessary to ensure clean water, optimal performance and a longer lifespan of the unit. But, as a new owner, you may not know how or how often you should be cleaning your filter. In the article below, we will discuss what needs to be done on a weekly, monthly and quarterly basis with your filter and what steps you need to take to keep it sparkling clean.


The Parts of a Filter


hot tub filter is comprised of three main parts, which is important to be aware of.


Core- The core is the main internal structure of the filter. This is what provides a powerful force of water flow - if the core of the filter cannot handle the integrity of the filter, the water flow will be affected.


Media- The media is the exterior fabric-like pleated material covering the filter. Water passes through the media, where dirt and debris become trapped.


End Caps- The end caps are just what they sound like. Plastic material at each filter end which attaches the filter to the spa plumbing.


Cleaning Hot Tub Filters


It is important to know right off the bat that you should purchase a new filter every year or so. Your filter may need to be replaced sooner if the end caps or media has been damaged. Keeping the filter of your hot tub clean is such an important part of hot tub maintenance. In fact, in certain circumstances, a dirty filter can void your warranty. 


Weekly Cleaning


Each week take a minute to remove the filters from your hot tub and rinse them with a garden hose or in the sink under the water tap. Spread apart the pleats in the media to remove trapped hair, dirt and debris. Allow the filter to completely dry before putting back in your hot tub.


Monthly Cleaning


Once a month, you will be required to clean your filter in a specialized chemical rinse. Make sure you ask your hot tub dealer which type of filter cleaner they recommended and buy a bottle when you get your hot tub so that you will be prepared. Remove your filter, spray down with the specialized cleaner and allow it to sit for 15 - 20 minutes. Thoroughly rinse with water and allow to dry before replacing. Make sure to really rinse well - if any spray cleaner has been left on the filter it will cause foam in your hot tub water once you put it back in.


Quarterly Cleaning


Every 3-4 months, the water in your hot tub should be changed. This is also the perfecttime to do a complete filter cleaning, otherwise known as a chemical soak. Remove the filter and place in the chemical solution provided by your dealer and let soak for 24 hours. Thoroughly rinse all of the solution off and allow to dry before replacing.


Additional Tips


Make sure that you never use regular household cleaning products, such as bleach, to clean your filter. Also, never place your filter in your dishwasher to be cleaned. Both of these scenarios will quickly damage your filter.
