Frozen in Time: Our Extra Hot Tub Filters

Regular Rinsing and Periodic Chemical Cleaning

For best water results, rinse off - with a garden hose - your hot tub filters weekly. (No more force than your standard garden hose spray attachment or you will tear the superfine fibers of the filter material.) Some people might think rinsing weekly is too often. However, we've seen proof that it works. [We have hundreds of hot tub owners/customers, and we witness daily what works and what doesn't.] Why then does a weekly rinse make sense?

All week long, whether you use the hot tub or not, particles collect on the pleats of the filters.(Of course, the more you use your hot tub, the more particle (dirtier) your filter(s) will collect. Hot tub chemicals are applied to hot tub water to kill contaminants and keep the water safe and sanitary. Simply put, they are referred to as "oxidizers". Basically, to oxidize something is to break it down. Sanitizing chemicals break apart - oxidize -algae, bacteria, etc.They will also try to keep oxidizing the dirt that collects on your hot tub filter. Dirty filters will create more demand for sanitizing chemicals (adding a lot more chlorine or bromine).

Rinsing weekly also prevents oil and dirt from permanently clogging the fibers that that provide a superfine filtering surface. Clogged filters will greatly reduce the water's ability to flow at the proper rate through the hot tub's heater. The hot tub is programmed to sense this and will shut off the heater to protect the hot tub. (No water flowing through the heater will cause the heater to burn up or even catch the hot tub on fire!) Permanently clogged filters are useless and must be replaced with new filters.

Remove your dirty filters and set aside for the moment..
...yeah  I thought I'd just rinse them off the next day.
The next day they froze.

Having an extra set of hot tub filters can be a great help for busy hot tub owners. As part of your weekly hot tub maintenance, simply remove the filters currently in use in your hot tub. Set these dirty filters aside for the moment. Replace with clean - DRY - filters. Now if time permits, rinse off the dirty filters you set aside. Store inside in a place where the superfine fibers of the filters can dry. Just keep repeating this rotation on a weekly basis. Hot tub owners that do this on a fairly consistent basis have gotten as much as 5 years use out of these filters. Hot tub owners that just don't have the time or the motivation to perform this regular, routine hot tub maintenance step - are replacing their filters annually. Note: If you are unable to rinse off your filters immediately, then place in a large container of water to soak until you can rinse them off the next day or two..

During the winter months, having an extra set of filters is a great when your garden hose is frozen and you can't rinse them off immediately.



Before removing your hot tub
filters for cleaning, remember to
turn off power  to your hot tub
by turning  the power off at
 your GFCI subpanel.

Why You Need To Periodically Chemically Clean Your Filter:  As noted just above, chemical cleaning of your filter aids removing greases, oils & other bather and environmental waste that will soil your filter and shorten its life.  Normal, regular 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 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 hot tub filter.

Add enzymes to your hot tub weekly, such as SpaGuard Natural Enzyme, on a weekly basis to control bio-film & organic waste build-up at the water line and on the filters. 
How do you chemically clean a filter?  That's easy. Use filter cleaning products such as SpaGuard® Filter Cleaner® that is used when you can soak your filter  for a several hours. 

Avoiding using power washers as they can damage the cartridge material. Tip: allow the filter to thoroughly dry before re-installing.
