Cons
While the Waterdrop system excels at scale inhibition, it’s important to note that it’s not a traditional filterit doesn’t filter out all water but only treats a portion to absorb polyphosphates, so it won’t remove sediments or particles. This means you might still need a separate pre-filter if your water has high sediment content. Also, the effectiveness can vary depending on local water quality, and the unit requires upright installation for optimal performance, which might limit placement options in some setups.
