Sand filter system for your hot tub - better than an EGO3 filter?
When choosing the right filtering system for your hot tub, many owners face the decision between traditional sand filter systems and modern filtering solutions like the EGO3 hot tub filter. While sand filter systems are widespread in swimming pools, it quickly becomes clear with hot tubs that the EGO3 filter is the far better choice. Here you will learn why.
Superior filtering performance for crystal-clear water
The decisive advantage of the EGO3 filter lies in its exceptional filtering performance. While sand filter systems can only filter particles from about 20-40 micrometers, the EGO3 filter achieves filtering down to 1 micrometer. This means that even the finest suspended particles, bacteria, and impurities are reliably removed from the water. Especially with the small water volume of a hot tub, typically 700-2000 liters, and the high water temperatures above 35 degrees, this precise filtering is crucial for hygienically flawless and crystal-clear water and simple hot tub water care.
Space-saving and perfectly sized compared to sand filter systems
Sand filter systems require considerable space and are often oversized for the compact conditions of a hot tub. The EGO3 filter, on the other hand, is specially designed for hot tubs and fits perfectly into any hot tub. No elaborate conversions, additional pumps, or separate technical rooms are necessary. Installation is very simple: Old filter cartridge out, EGO3 filter balls in – done.
Easy to maintain and durable
Another decisive advantage is the simple maintenance. Sand filter systems must be backwashed regularly, which not only wastes water but also means time and effort. Moreover, the sand must be completely replaced every few years – a dirty and tedious task. The EGO3 filter, by contrast, is very easy to clean: simply remove the filter balls, rinse them with clean water or wash them in the washing machine, and put them back. You can immediately see if the filter balls are clean and can reuse them for years.
Higher flow rate and better efficiency instead of backwashing filter sand
The EGO3 filter works on the swirling principle along free flow channels and can practically not clog. Unlike sand filter systems, where the flow rate significantly decreases with increasing dirt, the EGO3 filter maintains its high flow rate. This means: the hot tub pump works more efficiently, energy consumption remains low, and water circulation is optimal. The EGO3 filter even has a 2-3 times higher flow rate than conventional cartridge filters.
Pipe cleaning effect as a bonus
A special advantage of the EGO3 filter is the so-called pipe cleaning effect. Due to the high flow rate, even the finest deposits in the pipes are loosened and filtered out. This leads in the long term to cleaner pipes, less biofilm, and a lower chemical requirement in water care.
Conclusion - sand filter system versus EGO3 hot tub filter
For hot tubs, the EGO3 filter is clearly the better choice compared to sand filter systems. It offers superior filtering performance down to 1 micrometer, is space-saving, easy to maintain, energy-efficient, and specially developed for the demands of hot tubs. While sand filter systems are designed for large swimming pools, the EGO3 filter is the perfect, modern solution for crystal-clear and hygienic hot tub water.
