The major drawback of this unit was it’s filter system and lack of power. When comparing similarly priced Ionizers, there are a multitude of other choices which have more plates, more power, and less expensive filters. While measuring the pH of the machine, we noticed a marginal difference between what is advertised compared to actual results, although within acceptable ranges – the BHL-4200 was unable to achieve any impressive figures. They do offer an additional internal mineral filter to improve water quality, but there were no traces of significant minerals present in the final Alkaline water. The machine is covered by a 2 year Warranty.
Overall we have concluded that this machine is easily overshadowed by other, similar units in the same price range.
