Disadvantages of old paper cartridge filters
Old paper cartridge filters cause pools with bypass to only recirculate the dirt in a loop, while pools without bypass face the risk of circulation pump failure due to filter clogging.
Paper cartridge filter - a bacteria spreader
Clogged standard filter cartridges are also a perfect breeding ground for all kinds of bacteria, which can occur in such large numbers due to irregular cleaning that standard ozone devices or even salt systems (which are actually not recommended for whirlpools) can no longer kill them satisfactorily. Therefore, another disinfectant must be added, for example chlorine. It can be so simple, because essentially 3 things are essential for clean, beautiful, and odor-neutral pool water
- a strong disinfection system (e.g., ozonator),
- clean and fine hot tub filter as well as
- an optimal pH value.
So the customer usually cannot avoid cleaning the cartridge filters, unless they regularly buy new filters for the hot tub (2-4 times/year).
Paper cartridge filters need more chemicals
Additionally, the water requires more chemicals, and the pH value can fluctuate enormously and constantly with high particle load and poor disinfection, also requiring more time and chemicals. Oils and fats can only be poorly separated by a standard hot tub filter due to the too large pores in the filter material; a flocculant is needed.
Now this cleaning process is usually multi-stage and requires time, or ideally, you have a spare set of spa filters to be able to continue using the pool immediately.
Usually, chemicals or other equipment are needed again for cleaning and disinfecting such cartridge filters, etc. - that costs money.
So if you want to use your hot tub frequently and for longer periods, you also need additional time, money, space for utensils and cleaning, and at the same time produce huge amounts of waste....
Not with EGO3 whirlpool filters!
