Introduction of the Waterdrop K19 Countertop Reverse Osmosis System

Dr. Jonathan Doyle - Updated September 23, 2022
We all drink water daily, but only a few of us know the right amount of water our body requires within a day. The U.S. National Academies of Sciences, Engineering, and Medicine reported that men need 15.5 cups or 3.7 liters of water while women need 11.5 cups or 2.7 liters daily. The foods we eat provide 20% of this, while the other 80% comes from water, beverages, and other drinks.
Are you drinking enough water daily? If not, what are the challenges you face in drinking sufficient water? Not having easy access to safe drinking water is one of the leading causes of insufficient water consumption. That is why we highly recommend getting a portable countertop reverse osmosis system.

What Makes Countertop Reverse Osmosis System Stand Out?

Compared with traditional reverse osmosis system, countertop RO system combines the excellent filtration performance of RO system with the portability of countertop water purification products, the strong combination brings a more satisfying water purification effect.

Why Is Reverse Osmosis Systems Better?

There are five different levels of physical water filtration, starting with coarse filtration and ending with reverse osmosis filtration.
  • Coarse Filtration
  • Coarse filtration can filter out substances in the water with a diameter greater than 10um, including rust, sediments, and other large particles. Common coarse filter materials are PP cotton, steel mesh, and others.
  • Microfiltration (MF)
  • Microfiltration is an excellent method of removing sediment, algae, protozoa, or large bacteria. It also eliminates bad odor. MF membranes typically have nominal pore sizes on the order of 0.1–1.0μm. The regular MF filter materials include activated carbon, carbon rods, ACF, and others. MF is commonly used in conjunction with various other filtration processes, such as ultrafiltration and reverse osmosis.
  • Ultrafiltration (UF)
  • Ultrafiltration can be used for the removal of particulates and macromolecules from raw water to produce potable water. In many cases, UF is used for pre-filtration in reverse osmosis plants to protect the RO membranes, achieving 90% to 100% pathogen removal.
  • Nanofiltration (NF)
  • Nanofiltration is a membrane-based filtration method that relies on nanometer-sized pores to remove impurity particles larger than 10 nanometers in size. The pore sizes of nanofiltration membranes range from 1 to 10 nanometers, smaller than the pore sizes in UF and MF.
  • Reverse Osmosis
  • Reverse osmosis relies on smaller membranes than the nanofiltration membranes to remove impurities larger than 0.0001um. Therefore, it can separate unwanted ions and molecules from drinking water. It is also effective against viruses, and other dissolved solutes.
    Osmosis occurs in nature when a solvent moves from a region of low concentration to a region of high concentration, passing through a permeable membrane. As the name suggests, reverse osmosis is the opposite of this natural process. The process relies on hydrostatic pressure to forcefully move solvent molecules from a region of high concentration to a region of low concentration through a semi-permeable membrane. The high efficiency of the reverse osmosis process means it can remove up to 99.99% of contaminants in water. Click here to learn detailed explanation of reverse osmosis and how it works.

    Countertop Reverse Osmosis Water Filters

    The high purification of RO water filters is one of the reasons people choose them. However, this decision often has downsides like single application scene limitations, a challenging installation process, and large space requirements. Manufacturers have released improved countertop reverse osmosis water filter systems to eliminate these downsides.
    The countertop RO systems have simple designs yet efficient water purification performance. They do not alter your existing space design. Instead, they complement it and serve as a good fit for almost all spaces. You can install your countertop RO water filter system in your bedroom, dining room, living room, kitchen, or RV. It works continuously to provide clean, healthy drinking water once it is plugged into a power source, requiring no installation and plumbing.

    What Are Its Key Functions?

  • Easy Handling
  • The countertop RO water filter system requires no plumbing or installation and can be directly used after being powered on. Therefore, you can put the countertop water filtration system in a living room, a bedroom, an RV, or other places wherever you want to go.
  • Outstanding Filtration
  • The PP cotton, activated carbon, reverse osmosis, and UV light combination ensures the excellent filtration of water. The UV light achieves a 99.9% sterilization rate, bringing an incomparable water purification experience.
  • Energy and Cost Efficient
  • The countertop water filtration system K19 is efficient with water and energy usage. It produces only one cup of wastewater for every three cups of pure water and has a filter life of 12 months.
  • 170 oz Large Tank
  • The ergonomic tank of the countertop RO water filter system can conveniently contain 170 oz of water.
  • Easy for Filter Replacement
  • The twist and pull design of the filter unit makes it super easy to replace an old filter with a new one. First, turn counterclockwise to remove the old filter. Second, install the new filter and rotate it clockwise and downwards to the lock. Then hold the “Filter” key on the touch screen for 5 seconds for the filter reset, and the dispenser will enter the automatic flushing status.
  • Smart Design
  • An intelligent display screen shows the filter status, TDS value, present water volume, and other information in real time. The system allows you to choose from 4 modes of fixed water volumes in advance.
  • Applicable to Multiple Scenes
  • For the countertop water purification products, appearance design is an important reference factor for customers. Waterdrop K19 adopts a simple yet fashionable design, matching all application scenes, making it an eye-catching and highly decorative household appliance.

    Essential Facts about Waterdrop K19

    TDS Reduction

    TDS stands for total dissolved solids, which serves as a measurement of the total dissolved solids present in the water. The TDS level helps indicate whether the drinking water is fit for consumption, requires filtration, or is highly contaminated. Parts per million (PPM) is the measurement used for measuring TDS levels in the water. For freshwater, TDS is less than 1,000 ppm. Waterdrop K19 countertop RO system can effectively reduce TDS levels in the water and display TDS values in real time, reassuring your quality water drinking. It’s worth mentioning that bottled mineral water usually contains higher TDS levels than tap water. Drinking with Waterdrop K19 can not only bring you a healthy lifestyle, but also contributes to your part in plastic waste reduction.

    3:1 Pure to Drain

    The pure-to-drain ratio of the Waterdrop K19 countertop reverse osmosis system is one of the best in the present market. Thanks to its innovative drain water recycling technology, it produces only one cup of wastewater for every three cups of pure water. The 3:1 drain ratio helps reduce the amount of water used over time, helping you save more money in the long run. Drinking with Waterdrop K19 instead of plastic bottled water also helps protect the planet from the havoc of plastic pollution.

    Long Serve Life of Filters

    The filters in the Waterdrop K19 countertop RO system are known for their extended lifespan. You can use the filter for up to 12 months before replacement. This translates to 0.2 dollars daily to continuously enjoy a convenient water purification experience.

    To Round Up
