Yes, Zero Water Filters are designed to remove 99% of arsenic from water for the first 10 gallons that have been filtered. The effectiveness of removing arsenic is reduced to 98% after 20 gallons of filtered water.
Zero Water also offers a free online TDS meter that can measure total dissolved solids in your water, so you can see exactly how effective the filter is at removing arsenic.
The filter has been tested and certified by the American Society of Testing Materials (ASTM) to reduce the amount of arsenic as claimed by the manufacturer. It also meets NSF/ANSI standards 42, 53, and 401 for the removal of chemicals, heavy metals, and VOCs. So zero water filters can effectively remove arsenic.
What Is Arsenic?

Arsenic is a natural chemical element found in soil, rock, water, and air. It is usually released into the environment by activities like mining, burning coal or oil, and manufacturing certain chemicals. Arsenic is used in many industries including electronics, paint pigments, dyes, pharmaceuticals, and wood preservatives.
How Does Arsenic Get Into Your Water?

Industrial Plants: Arsenic can be released into the environment from industrial processes, such as mining and smelting.
Agricultural Activities: Arsenic can contaminate surface water and groundwater through runoff from treated agricultural fields.
Soil Erosion: Natural weathering of arsenic-containing rocks can lead to contamination of nearby surfaces and groundwater.
Old Corroded Pipes: Arsenic can also enter the water supply through leaching from older plumbing systems and corroded pipes.
The Negative Effects Of Arsenic
- It is highly toxic, even at low levels of exposure, and can cause serious illness or death when ingested for an extended period of time.
- Long-term exposure to small doses can cause a variety of health problems, including skin cancer, nerve damage, and reproductive harm.
- It is known to increase the risk of certain types of cancer such as bladder, lung, and liver cancer. It can also affect the heart and immune system.
- In high concentrations, it can cause neurological disorders, including seizures, and damage to the kidneys and liver.
- It increases the risk of diabetes, High blood pressure.
- In infants, it can cause developmental delays and learning disabilities.
What Type Of Cartridge Is Used In Zerowater

- Filter Screen
- Foam Distributor
- Activated Carbon And Oxidation Alloy
- Ion-Exchange Resin
- Ultra-Fine Screen
The Cartridge Used In Zerowater

ZeroWater filters use a patented 5-stage ion exchange filter that is designed to reduce arsenic from drinking water.
Filter Screen: The first layer of the ZeroWater filter acts as a pre-filter, trapping larger sediment and particles to help prevent clogging of the filter.
Foam Distributor: The second layer is a foam distributor, which helps ensure an even flow of water throughout the filter.
Activated Carbon And Oxidation Alloy: Coconut shell activated carbon and oxidation alloy reduce organic contaminants, chlorine taste, odor, and other contaminants such as mercury.
Ion-Exchange Resin: The fourth layer is composed of an ion-exchange resin which reduces organic contaminants, heavy metals like lead and copper, and dissolved solids, while also reducing arsenic.
Ultra-Fine Screen: The fifth and final layer is a fine mesh ultra-fine screen to trap any remaining sediment or particles.
Other Options For Removing Arsenic From Your Drinking Water

Distillation: Distillation is a process that involves boiling water and then collecting the steam in a separate container. The steam produced while distilling water will not contain any arsenic, as it evaporates before entering the second collection unit.
Reverse Osmosis: Reverse osmosis is a process where contaminated water passes through a special membrane, leaving behind pollutants, including arsenic. Reverse osmosis is an effective way to reduce the amount of arsenic in drinking water.


Anion Exchange: Anion exchange involves exchanging charged particles with more desirable ions. This process removes a variety of compounds and metals from water, including some forms of arsenic.

Activated Alumina Filtration: Activated alumina is a type of filtration media that can be used to remove arsenic from water. This process works by trapping contaminants in the tiny pores of the activated alumina, allowing clean water to pass through it.

FAQs
Does A Carbon Filter Have The Capacity To Eliminate Arsenic From Water?
Yes, carbon filters can help reduce the levels of arsenic in water. The amount of arsenic removed can range from 40-70%. The effectiveness of the carbon filter will depend on its efficiency and filtration capacity.
What Is The Best Way To Remove Arsenic From Water?
The most effective way to remove arsenic from water is by using a combination of distillation, reverse osmosis, anion exchange, and activated alumina filtration.
Is Arsenic Soluble Or Insoluble?
Arsenic is actually both soluble and insoluble in water. Inorganic arsenic compounds are generally more soluble than organic ones, meaning that they can dissolve into water more efficiently. As a result, it is possible for zero water filters to remove some levels of arsenic from drinking water. However, the exact amount depends on the type of filter used and the level of arsenic present in the water.
Conclusion
It is important to note that while these filters can help reduce the amount of arsenic in your drinking water, it is still important to test for its presence regularly. This can be done through a local water testing facility or with an at-home water testing kit. By staying on top of your water quality, you can ensure that the water you and your family are drinking is safe.
