When this is not a good choice
Every condition below is derived from this product's published specifications and from how it compares with the water treatment products we track — so you can check each one against your own room, supply or budget rather than take our word for it.
You live outside a metro or a major service town
HM Digital's service network is rated limited rather than excellent. Spare parts and callout times decide how a water treatment product holds up over the years, so check service for your pin code before you buy.
