Proper Hot Tub Filter Cleaning

Keep Your Water Clean

Cleaning isn’t just limited to things inside your home…the laundry piling up in the corner, the ring around the bathtub, or the dust bunnies collecting in every corner of the house. In fact, cleaning your hot tub is just as important as making sure the dishes don’t pile up in the sink. The longer your hot tub goes without a proper cleaning, the more likely it is that something will go wrong. The last thing you want to do is stress about your dirty spa water when you are kicking back and relaxing at the end of a long day. 

At Parnell Pool & Spa, we recommend that you keep your spa and filters as clean as possible to limit any potential issue. Spa filters are the number one part of your spa that keeps your water clean and are the frontline fighters against all the nasty contaminants/debris that is found in your hot tub’s water. Dirt, hair, beauty products, bacteria are just some of the things that your filters collect to keep your water looking and feeling clean. 

When/How To Clean

The best way to remember to clean your filters is to set up a weekly/monthly reminder of what needs to be done for your hot tub. 

  • Weekly Cleaning

Ideally, you want to do a quick rinse of your filters every week. To do this, remove your spa filters and give them a thorough cleaning with the “jet” setting on your garden hose. Make sure to spread apart the pleats and rinse each section completely to remove any debris.

A helpful hint is to not use a high-pressure washer to blast off the residue on your filters because it may tear or break the material. A filter flosser attachment is always helpful when spraying your filters each week. This easy to use tool attaches to your garden house and can give your cartridge filters a good, deep clean.

  • Monthly Cleaning

Every month, it is a good idea to do a deeper, more thorough cleaning of your spa filters to remove any build-up residue and contaminants that require more than a simple rinse. To do this, generously spray your filters with a cleaner such as SpaGuard Filter Cleaner and allow it to sit for 15 minutes. To clean, spray the filter completely with water and make sure all of the water running through the filter comes out clean (no bubbles).  

  • Water Change Cleaning

Every three to four months, it is best practice to complete a chemical soak for your hot tub filters. We recommend doing this when you change your hot tub water — think of it as “spring cleaning” for your spa filters. In a large clean bucket, dilute your filter soak chemical and submerge the filters for 24 hours (or at least overnight). Remove the filter from the soak and rinse completely. 

Whenever you clean your filters with a solution or spa filter cleaner, make sure to rinse the filters completely. If there is any cleaning residue left on the filter, it will cause your hot tub to foam, and you will likely have to drain and refill your spa. 

When To Replace Your Filters? 

Spa filters can wear out! Plan to change your spa filters once a year. If you typically have a high bather load and frequent your spa on a daily basis, you may have to replace them more often. At Parnell, we suggest that you purchase filters that are of higher quality, like Jacuzzi Brand Filters, so that you get more bang for your buck. We even recommend purchasing two sets of filters so you can rotate them each month to limit wear. 

Bottom Line

Clean filters are happy filters! When your filters are free of contaminants and debris, your hot tub water will be clean and silky smooth.
