In terms of performance and efficiency, both Waterdrop and APEC give each other a tough time to take the lead. The purification rate of both brands is
almost the same, i.e., 99%. Waterdrop takes a slight lead in terms of contaminant reduction, as it even targets
microscopic bacteria and TDS
particles.
The filtration procedures for both filters are similar because they feature RO membranes. However, Waterdrop is slightly advanced because it has a
composite filter technology, where a filter handles
multiple stages of filtration. At the same time, Waterdrop has many certifications, such as
NSF/ANSI 42, 58, and 372 certifications, and so on.
