Cartridge Filters. All cartridge
filters have 3 things in common:
1. They all use some type of pleated fiber
2. Dirty water enters in to the filter tank & flows through the
cartridge which filters out the dirt & debris (down to a size of about 10 - 20
microns - much smaller, but still visible dirt & debris & some algae).
Cleaner, filtered water is collected on the other side of the cartridge & pushed
out of the filter & returned to the spa.
Cartridge filters are used almost exclusively on spas & hot
tubs. Cartridge filters can be used with any hot water sanitizing system.
Because of their relatively large filter surface area (the pleated fiber
material can be as large as several hundred square feet as compared to under 4
square feet in the largest residential sand filter), cartridge filters generally
take a long time to get dirty between cleanings.
Care of Cartridge Filters: Clean only when needed.
Usually about once every 6 to 8 weeks.
Cleaning is accomplished by taking the filter
apart & hosing off the accumulated dirt & debris from the cartridge. Chemically
clean every time (after initial cleaning & at mid season) to break up
& remove accumulated greases, oils & dirt that has become embedded in the
cartridge material. Replace the cartridge about every 18 to 24 months of spa
Why you need to Chemically Clean your
filter: As noted just above, chemical cleaning of your filter aids
removing greases, oils & other swimmer and environmental waste that will soil
your filter and shorten its life. Normal, regular backwashing & rinsing
will not remove these wastes. Here's a couple of analogies that will help
you understand the significance of chemical cleaning: do you use shampoo on when
you wash your hair or do you just rinse it? Without shampoo, your hair
would be pretty matted & dirty after a couple of weeks. How about dirty
clothes? Do you only rinse them out in the washing machine or do you add
detergent to release & help remove the dirt & greasy stains? The same
thing goes with your pool filter.
Use enzymes such as SpaGuard Natural Enzyme or Natural Chemistry Spa Perfect on
a weekly basis to control bio-film & organic waste build-up even on the filters.
How do you chemically clean a filter?
That's easy. Use
cleaning products such as
SpaGuard« Filter Cleaner« that is
used when you can soak your filter (soak the elements or AquaFinesse Filter
Cleaning Tabs for removal of biofilm on the cartridge) for a several hours. Avoiding using power washers as
they can damage the cartridge material. Tip: allow the filter to thoroughly dry
The 6 Keys typically take about 30 minutes or less to accomplish
each week. Yes, that's it! Just 30 minutes. Now you can enjoy your
pool more & actually work less. In the long run, you'll also spend less
time & money.
