A Guide to Cleaning Your Hot Tub Filter
Ensuring that your hot tub and all its vital components are clean and fully operational is essential when looking to achieve the best bathing experience. Regular maintenance will keep your tub in top condition, and your hot tub’s filter is one key element that will need to be taken care of.
Along with your usual chemicals and water treatment system, your filter works to regulate your water and keep it clean. For this important function to take place, the filter’s efficiency must be maximised through regular cleaning.
Our guide explains how you can go about cleaning your hot tub’s filter to help guarantee your bathers’ safety and enjoyment!

As water circulates throughout your hot tub, it passes through the filter. If working correctly, your filter will catch any small debris and dirt, keeping your water clean.
The usual pleated, polyester filters ensure that the water going back into circulation is clean and safe for bathers.
As the filter is such a crucial part in the circulation process, you can start experiencing numerous issues if you go too long without cleaning and it becomes too dirty.
The following are some problems you will no doubt encounter when your filter is in need of some maintenance:
This is a big one as the filter is one of your main defences against contaminants in the water. Filters are designed to capture hair, dirt and bacteria; if a filter gets clogged with these things, it will become ineffective at filtering out any more debris.
Ultimately, this will mean that the water that filters back into circulation is likely to be dirty, leaving you with a less than desirable hot tub experience!
This has already been alluded to above, but when your filter is clogged, it becomes inefficient and can reduce the water’s flow level, depending on what filter and pump system your tub uses.
A low flow means that water circulation is slow; this can cause unnecessary strain on the pump and will reduce heating and the power of the jets.
A struggling filter will not only put strain on other components, but a very dirty filter can also contaminate certain other parts that are essential to your hot tub.
Dirt from the filter or uncleaned water can end up in the heater, pumps and sensors. Unsurprisingly, this can negatively affect these parts and cause further problems.
So, how do you go about performing this necessary maintenance task?
There are numerous ways to clean your hot tub filter, but sadly it is not a simple case of depositing your usual chemicals in the water and letting them run through the system.
Below, we cover the options.
This is one of the easiest ways to clean a filter and should be the most regular method in your maintenance arsenal.
Remove your filters and rinse them thoroughly with clean water; this can be done with a garden hose or in a big enough sink.
Make sure that you get between each pleat to confirm that every bit of visible dirt or debris is removed.
Let your filter dry before reinserting it back into the tub.
You should look to clean your filter this way around once a week to ensure that you are keeping it in the best condition.
It should be noted that this is not the best method for getting rid of grease and oils, for that you will need something more extensive than water alone.
This option is more thorough than a simple water rinse and should be used monthly. This is a good option if you are trying to combat the grease and oils that collect in your filter.
It is often a good idea to give your filter a quick rinse with water if there are any large bits of dirt, then you can spray your filters with a specialised filter spray. After you have done this, leave it to sit and work its magic for about 15 minutes.
You can also use a brush to help gently lift ingrained dirt.
After the 15 minutes are up, you should thoroughly rinse the filter in clean water and leave to dry before putting it back in your tub. If you do not rinse the filter properly, you may experience foaming.
This is the most time-consuming method and should be undertaken less frequently than the above options, with a schedule of every three or four months. This timeline should align with when you change your hot tub water.
A soak is the most intensive cleaning method as it will allow the cleaning agents to reach every fold.
Once again, it is a good idea to quickly rinse your filter to remove larger debris before attempting a soak.
Here, you should add your chosen filter soak chemical to a large, clean bucket, paying attention to the instructions when it comes to dilution. Once you have done this, you can add your filter to the bucket, ensuring it is fully submerged in the diluted chemical solution.
Leave the filter to soak overnight or, ideally, for a full 24 hours. When the time is up, rinse the filter with water and allow to dry before returning it to your tub.
Although it can be tempting to take shortcuts, this can often do more harm than good and will cost you in the long run!
1. Don’t Use Bleach – It is too harsh for the filter’s fibres, even when diluted.
2. Avoid the Dishwasher – Using the dishwasher is often a bad idea for normal polyester filters as the media can become damaged.
3. Stay Away from Household Cleaners – Using regular household cleaners can cause problems with foaming even when you think the filters have been thoroughly rinsed.
