Fiber filter balls or cotton balls - the crucial question
For several years now, the ego3 hot tub filter a completely new filter option for whirlpools. Our filter makes use of the excellent filter properties of 3-dimensional filter balls and is therefore far superior to the old filter cartridges in terms of filter performance, filter capacity and ease of use.
And they are also much cheaper and do not produce any residual waste, but only recycling Müll and only very little.
What "filter balls" are there?
In the meantime there is different filter balls on the market. These can be divided into two categories:
fiber balls filter balls
These are made of recycled PET continuous fibers that are suitable for the Zero Dirt technology. There are also different versions of the fiber balls (e.g. in blue, gray, green without bacterial protection for Koi ponds, green with bacteria protection=original ego3 filter ball). These variants are optimized for the application in terms of diameter, fiber thickness and composition. Therefore, you should only use original ego3 Filter balls for your hot tub These are exactly the right size/fiber stiffness for the pressure conditions in whirlpools. This guarantees that it is the cheapest and best Lsolution. Just because fiber balls (such as blue Fibalon pool filter balls) are cheaper, that is not really an advantage, since the lifespan is much shorter due to the thinner fiber. These blue fiber balls are optimized for sand tank systems (with backwash) for swimming pools with 10 times less suction. The best combination of price and durability are the original ego3 filter ballsOtherwise we would use and sell other filter balls!
cotton balls filterballs
(mostly in white) - a very cheap variant of round filter material. Unfortunately, these are completely unsuitable for our intended use in whirlpools and swim spas. Their structure is far too compact/dense and their firmness is far too soft for our hot tub Pressure conditions. These balls clog the ego3 Filter system within a very short time and must therefore be changed again within days, which unfortunately means that the cost advantage is already gone. In addition, there is a risk that if these clump together, such high pressure in the ego3 The bottom or the entire container can break. The pumps are immediately affected when these cotton balls become compacted and in the worst case scenario, the pump burns down or the container breaks and parts of it destroy the pump or clog pipes.
cubes or cylinders made of fibers
Another special form is cubes or cylinder discs made of fibres. Cubes are punched out of filter mats. These are made of a similar material to fibre balls but have three crucial disadvantagesFirstly, they are not as stable in structure as filter balls and therefore clog the filter very quickly. Secondly, due to the square shape, they cannot be used in the filter container with the hot tub Application necessary intermediate channels, as they arise with round filter balls, in the ego3 Filter containers are arranged, which again leads to rapid clumping and thirdly, countless fibres come loose from the filter cubes and end up in the water because the edges are cut and thus the fibres are interrupted.
We have tested all variants very extensively and are constantly testing new filter balls Products. And so far only the green filter balls with disinfectant effect are 100% suitable. All other variants are unfortunately not even close to suitable. They are actually just copies of the form or the material without taking the necessary properties into account. Unfortunately, the manufacturers completely lack the know-how of what a filter ball can do for a hot tub Unfortunately, just being round or made of one fiber is not enough.
Therefore use only original ego3 filter material!
No other filter material offered is even remotely suitable for the intended purpose and will cost you more work and money combined with the risk of damage to the ego3 filter container or your hot tub.
