How do countertop gravity water filter works

Gravity water filters use gravity to push water into the filter to remove contaminants. There are two types of gravity water filters countertop and hanging.

Both types have two chambers, upper and lower. The countertop has a chamber made from plastic or stainless steel, while the hanging is made from silicone and is ideal for travel, backpacking, or hiking.

A countertop gravity water filter uses gravity to pull water through the filter. It consists of two chambers: the upper and lower.

The upper and lower chambers are divided by the filter.

When you add unfiltered water to the upper chamber, it passes through the filter or cartridge that is in between. The filter removes all contaminants, and filtered water goes through the lower chamber.

The lower chamber is where filtered water is stored and has a spout or spigot where treated water gets out.

Advantages of countertop gravity water filter

  • It requires no electricity to operate.
  • No installation is required.
  • It can sit on a tabletop, a desk, a water filter stand, or a kitchen top.
  • It can be used in areas with no running water at the tap.
  • It requires low maintenance; you are only required to change the filter and clean the chambers.

Disadvantages of countertop gravity water filter

  • It is tiresome to keep on adding water.
  • The water filtration process takes a long time.

What to look for when buying

  • Space

The countertop gravity water filter requires space to sit on either the countertop, desk, or table. Make sure the space you choose will fit because they come in different sizes.

  • Chamber size 

As said earlier, the countertop gravity water filter consists of two chambers: the upper and the bottom. The upper holds unfiltered water and the bottom holds filtered water, so you know how much amount of water each chamber holds.

  • Contaminants it removes

Every water source has different contaminants. Make sure you choose a unit that removes contaminants present in your water source.

  • Filter replacement

The countertop gravity water filter uses a cartridge that does not last forever. After treating water for some time, the cartridge needs to be replaced. Do you know after how long you are supposed to change the cartridge?

Most cartridges last for roughly 6–12 months.

See our page about countertop water filter replacement cartridges for help choosing the right filter for your system.

  • Chamber material

Chambers are made of different materials, such as stainless steel, plastic, or even glass.

Choose the material that suits you.

  • Additional features

Remineralization stages- some countertop gravity water filters have a stage called remineralization. Such a unit not only removes contaminants but adds important minerals such as calcium and magnesium that increase the PH of water from 7 and above, providing alkaline water.

When it comes to certification, AquaMetix is made from the highest quality NSF component certified (ANSI 61), coconut shell-based activated carbon, and other superior adsorbent materials, including B2 (ANSI 61).

Both ceramic shells and AquaMetix granular combine mechanical filtration and physical adsorption processes to remove a wide variety of contaminants.

Ceramic shells reduce suspended solids, pathogenic bacteria, cysts, chlorine, chloramine, volatile organic compounds, MTBE, lead, mercury, asbestos, arsenic, and fluoride.

The CeraMetix elements have been tested in accordance with NSF protocols for cysts, turbidity, particulates, lead, chloramines, and chlorine reduction.

The upper reservoir holds 1 gallon of water ready for filtering, and the lower reservoir holds 2 gallons of filtered water ready for use. 

It is pottery made with an off-white glaze finish.

When fully assembled, the AquaVas measures 20” high with the lid in place, and its diameter is 9.5” wide.

  1. Nikken 1 Waterfall Gravity Water Filter Purifier System (1384)

  • Chamber capacity: Fill tank: 1.32 gallons/5 liters; supply tank: 1.45 gallons/5.5 liters (with mineral stones).
  • Materials in the product: Pi material, mineral stones, recyclable polymer, ring magnet (1,200 gausses)
  • Filter life: Filter cartridge: 90 days or 900 liters and Mineral stones: once per year.
  • Size: 17 L x 13 W x 9H inches.

Nikken 1 Waterfall The Gravity Water Filter Purifier System utilizes multiple filtration stages that include:

  • natural carbon filter that captures microscopic particles. This is a charcoal carbon filter that filters water using adsorption principles.
  • mineral stones that produce alkaline water. It adds natural minerals and adjusts the pH value to the 8.5-9.5 range.
  • Corrosion-protected magnets produce a magnetic field surrounding the direction of water flow to reduce sediment agglomeration. 

How it works

Tap water is poured at the top of the gravity-fed system, it passes through the filter, then mineral stones, and finally through a magnetic field.

The Nikken Waterfall has received the coveted Gold Seal of Approval from the Water Quality Association of America.

It is WQA tested and certified according to NSF/ANSI 42 for the reduction of Aesthetic chlorine, Taste and Odor, Chloramines, and Particulate Class III, NSF/ANSI 53 for the reduction of VOCs and Mercury, and NSF/ANSI 372 for low lead compliance as verified and substantiated by test data.

The system comes with a filter and mineral stones. The filter cartridge lasts 90 days or 900 liters, whichever comes first. mineral stones once per year.

It is recommended to change the filter once it treats 900 liters (230 gallons) of filtered water or 3 months of use. To know the exact time to change the filter, the system has an indicator. Once it turns red, it is time to change. The mineral stone is changed once a year or every three filter changes.

The filter is for cold water only and must be soaked in cold water for 8 hours before installation.

This cartridge provides 12 gallons of filtered water each day.

  1. Santevia Gravity Water System – Countertop Model

  • Capacity: The top tank has a capacity of 5 liters (1.32 gallons), while the bottom tank has a capacity of 10 liters (2.64 gallons).
  • Material: BPA free plastic 
  • Filter life: Santevia 5-Stage Filter is good for 4-6 months, Ceramic Pre-Filter 1 year, and mineral stones 5 years.
  • Size: 13Lx13Wx10H

Santevia filters water in eight stages.

Stage 1: 0.3-micron Ceramic Pre-Filter: removes rust, sediments, bacteria, germs, and parasites.

 Stage 2: Granular Activated Coconut Carbon: It filters chlorine, herbicides, pesticides, pharmaceuticals, industrial chemicals, trihalomethanes (THMs), heavy metals, organic chemicals, odor, taste, color, and particulates. This stage also contains a KDF filter medium that inhibits the growth of bacteria in the filter and neutralizes heavy metals. 

 Stage 3: Volcanic Mineral Zeolite

 This stage inhibits bacteria and neutralizes heavy metals including lead, nickel, cadmium, and mercury through an ion exchange process. It filters detergents, ammonium, certain radioactive ions, agricultural chemicals, and other toxins.

 Stage 4: Mineral Stone Infusion

 Highly porous Maifan mineral stones infuse ionized minerals into the water that aid in oxygenation and alkalization.

 Stage 5: pH Mineral Balls

 Mineral ions encased in diatomaceous earth add calcium, magnesium, and other trace minerals to fortify the water and increase the pH.

 Stage 6: Energy Balls

 Constructed from highly compressed and fired earth and mineral oxides, the energy balls assist with pH balancing and emit beneficial infrared energy into the water.

 Stage 7: Mineral Stone Immersion

 During this stage, mineral stones continuously release easily absorbed, ionized minerals into the water, including calcium, iron, magnesium, potassium, zinc, and other trace minerals.

 Stage 8: Magnetic Energy

 Embedded in the Santevia water spout, aligned magnets are suspended in the water, simulating the magnetism emitted by the earth’s core and the forces created as water flows over magnetic, mineral-rich rocks in nature. The magnetic energy breaks the water molecule clusters into smaller structures for greater bio-availability and maximum absorption.

It is made of BPA and BPS-free plastic.

It is suggested not to leave filtered water sitting in the container bottom, as this will diminish the service life of the mineral stones and may add unwanted mineral content to the water. For best results, transfer filtered water to a serving pitcher.
