Disadvantages of old paper cartridge filters
Old paper cartridge filters not cleaned regularly cause pools with bypass to only circulate the dirt in a circle, while pools without bypass even risk the infarction of the circulation pump due to filter clogging.
Paper cartridge filters - a bacteria spreader
Clogged standard filter cartridges are also a wonderful breeding ground for all kinds of bacteria, which can occur in such numbers due to irregular cleaning that standard ozone devices or even salt systems (which are actually not recommended for hot tubs) can no longer kill them satisfactorily. So 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 filters 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 demands more chemicals, the PH value can also fluctuate enormously with high particle load and poor disinfection and also requires more time and chemicals. Oils and fats can only be poorly separated in 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-step and requires time or ideally you have a replacement 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, you additionally need time, money, space for utensils and cleaning, and at the same time produce huge amounts of waste....
Not with EGO3 hot tub filters!
