## Description

Upgrade your countertop water dispenser with this high-performance RO filter. It reduces TDS, heavy metals, and other impurities for clean, fresh-tasting water.

Review: Quality Filter - Would recommend. - I am happy with the quality of this water filter. It filters out metals, chlorine, fluoride and kills harmful contaminants in water. Easy to install. As this filters out good minerals as well as bad, I think I am correct in saying there is a need to take calcium and magnesium to replace these minerals normally ingested via tap water. Please check this information for yourself although I'm about 90% sure I have this correct.
Review: Super easy to fit and replace provides great filtered water - We use the Waterdrop machine multiple times each day, the filter lasts around 12 months and is easy to fit and replace in the machine. Comes cellophane sealed so nice and fresh when ready to install.

## Features

- This filter is adaptive to WD-K19-H.
- [Superior Filtration Performance] The innovative RO membrane is designed to reduce TDS, chromium, pfas, fluoride, arsenic salt, iron, radium nitrate, calcium, particles, chloride, chlorine and heavy metals.
- [0.0001μm Pore Size] Its superior RO membrane can intercept any impurities larger than 0.0001 micron. This means it can trap most harmful substances in tap water.
