HOT TUB FILTER CLEANING
How to Clean Your Hot Tub Filters
Cleaning your hot tub filters improves their efficiency and helps maintain sparkling water.
You should establish a routine filter cartridge cleaning cycle based on the amount of hot tub use and the sanitizer you use. Cleaning hot tub filters every 2 or 3 weeks is the most usual routine. If you use Aquafinesse you will find it preferable to clean your filters weekly. If you use Eco One you will probably find if sufficient to clean them monthly.
Remove
the cartridge from the filter housing and use a garden hose with a
straight flow nozzle or a tap to wash down the filter element.
Work from the top of the filter, with the water flow at a 45 degree
angle, and wash all pleats, ensuring that you remove an debris stuck
between the pleats. Alternatively use our magic
Water Wand or
Easy Clean Nozzle or, to make life really easy, try
the brand new
Blaster Filter Cleaner
Rinse the filter until all dirt and debris are gone.
Soak the filter cartridge for at least 1 hour
(overnight is preferable) in a clean, suitable size bucket using a
proprietary filter cleaner solution. Our
filter soak container will accommodate most filter sizes.
Alternatively spray with
Clean 'n Clear and rinse thoroughly after 10 minutes.
If you want to make it really easy, place the filters upright on the
bottom shelf of your dishwasher, place
filterONE,
Filter Brite or
AquaSparkle
Immerse in the powder compartment and run the machine on a
standard 50 degree wash cycle. If you use a dishwasher
you must make sure that your filters can stand vertically.
Rinse the cartridge again to remove any traces of
cleaning solution.
Always dry the filterst before reinserting
them back into your hot tub. This ensures that the filters perform
optimally and last longer. Let them dry naturally, don't use
artificial heat. It is a good idea to keep a spare
set of filters and rotate them at each clean so that they can dry completely before reuse.
Finally, any grit or debris
inside your filter compartment can easily be removed with a
spa vacuum
cleaner.
IMPORTANT INFORMATION FOR BAQUASPA USERS
BaquaSpa is a coagulant which combines bacterial cells and other small particles into particles large enough to be trapped by the hot tub filter. The resulting deposit is a grey sticky film which can only be removed with BaquaSpa Filter Cleaner or an alternative compatible product, such as Splash Spas Filter Cleaner. If any other cleaner is used prior to stripping the film, the cleaner and the film will combine to form a gum like substance which cannot be removed and your filter will have to be replaced.
Blaster Automatic Filter Cleaner
The Blaster Automatic Filter Cleaner prolongs filter life. the Blaster
automatically rotates cartridge filters whilst a series of powerful jets
direct water to clean between the filter pleats.
The Blaster cleans the filter horizontally allowing the dirt and debris to easily fall from the filter and avoid the risk of it sticking as with vertical or upright cleaning.
To use, simply connect the Blaster to a hose using the hozelock connector (supplied) and rest the spa filter in the Blaster cradle. It takes just a few minutes to clean most filters.
