Spa and Hot Tub Filter Cleaning Tips
Normal weekly cleaning of your filter is required as directed by the spa manufacture when using
Nova Spa Water Conditioner.
Filter Cartridge life and its effectiveness depends on proper maintenance. A dirty filter has the
potential to increase the load on the water pump motor and reduces the effectiveness of the water
heater. During use, filter media begins to lose its filtration ability because it becomes clogged
with particles and other contaminants. This causes the water pump to work harder in order to
push the water through the filter and can result in damage to the pump and motor and/or rupture
the filter. A ruptured filter allows particles and contaminants to freely circulate throughout the
water and deposit on anything with which they come into contact.
Best indication of a clogged or ruptured filter cartridge is an increase in water pressure or no
pressure within the cartridge's housing canister or a visible decrease in the systems water flow
rate. Filter cartridges should be rinsed and cleaned at least once every month or more often if
necessary. The filter cartridge should be cleansed of coarse dirt and debris by pressure washing
inside and out with a garden hose. Apply the water stream at a 45 degree angle and spray between
each filter pleat to make sure all foreign matter is dislodged.
Fine particles of dirt are more easily removed from the filter pleats by a gentle brushing after the
cartridge has been allowed to dry. Caution, do not scrub the pleated surface areas of the filter or
apply a stream of compressed air to the filter surface to remove fine particles, because doing so
can damage the filter media.
Algae, suntan oil, and body oils can form a coating on the filter, which may not be thoroughly
removed by hosing. If these contaminates are left on the filter media the media's efficiency is
reduced and will become clogged more rapidly. Therefore, it is a good practice to remove these
contaminates from the filter cartridge before replacing it.
We recommend soaking the cartridge in a solution of Penetrating Spa Cleanser cleaner to clean
algae, oils, and other gunk from the filter media. Follow the manufactures' directions for proper
use. Allow a minimum of one hour for soaking, and then hose the cartridge thoroughly before
re-installing in the filter housing.
TIPS:
We recommend that filters be replaced yearly. If rotating the filters, then every other year. Use
the rotation method of filter maintenance: while your dirty filter is soaking in a cleaning solution,
replace it with a clean dry spare.
Never use a power washer to clean filter cartridges, the high pressure water will damage the
filter media. Never use household bleach to clean filters. Although bleach may seem to do an
adequate job of cleaning, it degrades and weakens the fibers in most filter media, thereby
decreasing the useful life of the filter.
