Filter balls are the backbone of our innovative unique filter method.
There are various filter balls on the market. Basically, they can be divided into 2 main categories:
Fiber balls:
These are filter balls made from continuous fibers, just like the Ego3 filter balls. There are also various versions here depending on the application. There are specially optimized ones for swimming pools, machine tools, and pond systems. Ego3 filter balls for Ego3 hot tub filter are, for example, specially optimized in terms of fiber and composition for use in whirlpools to offer our customers the best value for money. Their advantages are:
- hardly any flow resistance due to the open structure
- very high dirt absorption due to the open structure
- very easy to clean also due to the fiber structure
- filters out every particle from 1 micron
Cotton balls (mostly white):
These are filter balls made of compressed cotton. They are very dense and compact. Actually, this is a Chinese imitation of fiber balls, but just an imitation, because there is a patent and a lot of know-how involved. Their disadvantages are:
- expensive, although they cost very little, because you need much more due to the short shelf life and the difficult cleaning
- clumping: the filter balls are much too dense and this quickly leads to clumping and flow problems in the pool and hot tub (they cannot be backwashed in the pool either)
- difficult to clean, as the dirt is hardly removable from the dense filter ball structure
- must be cleaned very often.
In summary, it can be said: Filterballs made of fiber material are the right and best solution for water filtration and hot tub water care. Filter balls made of cotton are a cheap and poor copy of fiber filter balls, which, although cheap, are expensive overall and require much more effort or can even damage the hot tub.
