Arsenic removal systems come in different styles and can offer many different features. When considering the best option for you, it’s important to focus on the features that mean the most for you. For example, installation, how they work, and specific elements they remove can be key features to consider.
After testing various units closely, we are ready to present you with the best units in the market.
Undetectable through both taste and smell, arsenic is a concern even the lowest level. Thankfully, scientists have created several options to detect arsenic and ensure we’re safe.
Below you will find tested and approved models that keep you safe from this invisible and hazardous contaminant.
Two Types of Arsenic
There are two types of arsenic: organic and inorganic. Inorganic arsenic forms when organic arsenic combines with other elements, like metals. Often found in water, the two most common and harmful types of inorganic arsenic are known as As-III and As-V. By comparison, organic arsenic is attached to carbon and typically absorbs into ground materials, not entering your water.
Best Ways to Remove Arsenic
One way to remove arsenic is via reverse osmosis. However, you need to buy a reverse osmosis water filter, which typically won’t remove everything because it’s not made specifically for arsenic removal.
There are other ways to remove arsenic as well, but these are often more complicated. For example, you can absorb arsenic via coagulation with lime, through activated alumina, or via the ion exchange. However, to ensure the best results, it’s best to use a dedicated arsenic removal system.

Frequently Asked Questions
What Are the Main Features and Benefits of Arsenic Removal Systems?
The most effective feature of these systems is their ability to absorb arsenic from drinking water completely. Furthermore, these systems remove many other contaminants that affect water quality.
Although arsenic can not be sensed, those other contaminants may affect the taste and smell of your water. When you remove them, your water is not only safer but also cleaner, fresher, and odorless.
Arsenic Removal Systems vs. Reverse Osmosis Systems
Reverse osmosis (RO) works with membrane purification to remove various impurities. Although it can remove some arsenic V, it still can’t remove arsenic III. Converting arsenic III to V is possible, but is a much longer process, meaning you’ll need to invest more time into a complex system to ensure all arsenic is removed.
Due to the challenges with reverse osmosis systems, dedicated arsenic removal systems were created. While these options often absorb other contaminants, too, their primary goal is to remove arsenic. Although they cost a bit more than casual water filters, they do a fantastic job, removing arsenic more efficiently and with less complexity compared to RO systems.
What is Whole House Arsenic Protection?
Systems that offer whole house protection are usually installed at the water entry point of your home, directly after the pressure tank. This approach means the unit will be capable of cleaning the water throughout the entire home, both hot and cold. Therefore, your whole house will be protected from any arsenic contamination.
Do I Really Need an Arsenic Removal System?
There are many filters on the market that have arsenic removal as an added benefit. Therefore, you may not have to purchase an entire system. However, if you are living in an area with high amounts of reported levels in the water supply, it is best to have a unit dedicated to the removal of arsenic specifically.
Does Boiling Water Remove Arsenic?
According to the Centers for Disease Control and Prevention (CDC), Boiling water can actually possibly increase arsenic levels. Due to the water evaporating, it concentrates the levels of arsenic in the water. Based on this guidance, we don’t recommend boiling water to try and remove arsenic.
Are Arsenic Removal Systems the same as Water Filters?
Generally, yes. There are a lot of arsenic removal systems on the market that also filter out common contaminants. Overall, it is just a matter of paying close attention to what your unit filtration does and does not cover.
Final Thoughts
If your water has arsenic, you need to get rid of it immediately. Even if you suspect you may be at risk for arsenic in your water, you should look into an arsenic removal system. You can either buy one of the proven arsenic removal systems that WaterFiltersAdvisor reviewed or shop on your own.
In any case, be sure to check our buying tips and, before buying, clarify your needs. Arsenic removal systems are quite an investment, so be sure to do your research and buy the unit that will best meet your unique preferences and needs.
