为给水壶除垢烦恼中,想起磁化去垢。接着搜索了一下,在茫茫广告中发现这个。

虽然磁化有益健康是伪科学,幸运的是文献显示防水垢还是有效果的。

The Effectiveness of a magnetic physical water treatment device on scaling in domestic hot-water storage tanks. C. Smith, P Coetzee and J. Meyers. Water SA 29(3) 2003. Available as a PDF download.

These South African authors have produced what strikes me as a very well-done study, one of the few that reports scientifically credible evidence for the effectiveness of MWT. Their series of experiments in which one of two parallel heaters was fitted with a permanent magnet device showed scale formation reductions varying over a rather wide range (17-70%), with an average of 34%.
