How to Clean Hot Tub Filters
In most cases, we recommend you replace your filter(s) at least once per year (Maximum life is 2 years). There are exceptions to this rule…
- The first exception is the Tri-X filter which are can last up to 3 years with regular cleaning. This filter is found on many models of the Hot Spring Highlife Series and does not have the traditional paper filter look, but rather a hard ceramic like material.
- The 2nd exception is the Artesian Island Series filter, which needs to be replaced very four to six months. You will easily recognize this filter because it is purple.
Your spas filter(s) protects not only your health, but also your wallet. In some cases, dirty filters can void your warranty, so we recommend that you clean your spa filter(s) every two weeks.
Cleaning Options For Your Hot Tub Filters
Regular cleaning of your filter(s) will prolong the life of the filter(s), and hot tub . At Coastal Spa and Patio we recommend one of three methods. Watch this video, or read on for more detailed instructions on the various options for cleaning your hot tub filter(s).
1. Rinse Filter with Water (Every 1-2 Weeks)
Turn off the power to your hot tub. Remove the filter(s) from your hot tub and rinse with a garden hose. Be sure to rinse between each pleat to get any dirt, hair, or other debris out.
2. Instant Chemical Rinse (Once a Month)
Purchase a bottle of Freshwater Instant Filter Cleaner. Spray your hot tub filter(s) with the cleaner and allow to soak for 15 to 30 minutes. Then, using the same method as above, rinse down with with a hose. Please make sure that you throughly rinse well. This will reduce the possibility of foam in your spa when you turn on the jets.
3. Overnight Chemical Soak (Every 4 Months)
It is recommended that you change the water in your hot tub every four months (every six with the ACE Salt Water System). It is at this time that we suggest you do an overnight chemical soak of your filter(s).
Using a bottle of Freshwater Filter Cleaner, and in a large bucket (enough to fill and submerge a filter), dilute the product as per the directions on the bottle. Let the filter rest in the solution overnight or 24 hours.
When the soaking is completed, you will want to throughly rinse the filter. This will reduce the possibility of foam in your spa when you turn on the jets.
The “Not To Do List” When Cleaning A Filter
You do not want to damage your spa or filter(s) when you clean them, so we have put together a list of things that you should not do when cleaning your hot tub filter(s).
1. Do Not Use Bleach
Bleach may be great for cleaning around your home, but it is not good for your filter(s). It will whiten them, but the bleach will damage the fibers in the filter, breaking them down, and greatly reducing the life of the filter.
2. Do Not Household Cleaners
Just like beach, household cleaners are great for cleaning, but you will want to avoid using them. They may be safer than bleach, but the foam residual when you go to use your spa could be a nightmare. Better to be safe, than sorry.
3. Do Not Use A Dishwasher
You might be able to fit a filter in the dishwasher, but we do not recommend putting them in there. The dishwashers powerful wash may be more than the filter can handle and it could damage the fibers in the filter, and reduce the quality of the filter.
Exception: There is one exception to the dishwasher rule, and that is the Hot Spring Tri-X Filters. Because they are made of a harder, ceramic like material, you can put them in the dishwasher. However, you should never use soap, and turn the dry cycle off.
- Purchase a spare set of spa filter(s). While you are cleaning one set, the other can be used in the spa.
- If you have more than one filter, and one of the filters is dedicated to a 24 circulation pump, like the tires on your car, routinely rotate the filters so that the filter that is on the 24 circulation pump does not wear out quicker than the other filter(s).
- If there is a ribbon around the filter at the time of purchase, do not remove this. It will protect your filter and maintain a longer life if it is kept in place.
