Comparison with the standard water desinfection method
| Chlorine | Copper/silver |
| 1. Permanent pH monitoring required, at least once weekly | 1. No necessity for pH monitoring |
| 2. Permanent chlorine monitoring required, at least once weekly | 2. Measurement of copper levels every 3 months |
| 3. Causes reddened, irritated eyes | 3. No eye irritation |
| 4. Causes dry, flaking skin | 4. Silky soft skin |
| 5. Storage of the product and frequent replenishment | 5. Electrodes have a life of 4 - 5 years |
| 6. Marked odour, particularly in public baths | 6. Water with neutral odour |
| 7. Corrosive risk to users, particularly if fluid chlorine is used | 7. Fully automatic, risk-free release of ions |
| 8. Use of additional agents required to regulate pH | 8. No agents required for pH regulation |
| 9. Bath requires supervision over longer periods of absence | 9. No supervision necessary during absence |
| 10. Use of additional flocculators necessary | 10. Automatic flocculation |
| 11.Use of agents necessary during winter breaks | 11. No algae formed during winter periods |
| 12. Use of algaecides necessary | 12. No additional algaecidal agents required |
| 13. Showering advisable after bathing | 13. Bathing in drinking quality water |
| 14. Can cause irritation of respiratory tract | 14. Water contains no irritants |
| 15. Risk of corrosive effects on pool elements and environment | 15. No corrosive characteristics |
| 16. Hard water | 16. Detectably softer water thanks to electrolysis |
| 17. Low buffer capacity | 17. Constant release of ions |
| 18.Chlorine is a potential health risk | 18. Copper is healthy (essential element). |
| 19. Expensive to maintain | 19. Maintenance cost less than 50% of chlorine systems |
| 20. Requires extensive maintenance | 20. Minimal maintenance |
| 21. Chlorinated water should be changed once annually | 21. No water change necessary |
| 22. Replacement of filter sand every 2 – 3 years | 22. Replacement of filter sand every 10 years |
| 23. Expensive when basalt and hydroanthracite are used | 23. Standard quartz sand can be used for filters |
| 24. Rapid loss of efficacy if exposed to strong sunlight | 24. Environmental influences have no effect |
| 25. Backwash water must be discarded | 25. Backwash water can be used to water plants |
