The Best Water Filtration System to Remove Arsenic and Other Toxic Chemicals from Water

Arsenic is a natural element that occurs in rocks and soil – and nowadays – in our precious drinking water. In excess amounts, inorganic arsenic can quickly make its way into ground and surface water as a byproduct of mining and other industrial processes, as well as through agriculture, where it is used in fertilizers, pesticides, and herbicides.

Because arsenic is odorless and tasteless, it can go undetected and affect the human body with dreadful symptoms such as stomach pain, diarrhea, vomiting, nausea, thickening and discoloration of the skin, numbness in the hands and feet, blindness, and partial paralysis. Long-term exposure to this dangerous chemical can have more chronic symptoms, and can even lead to death.

Considering these frightening health concerns, you might be wondering how to remove arsenic from water, especially if you’ve tested positive for the chemical in your home’s water supply. To get the job done effectively, you’ll need more than just a standard carbon filter. The best water filtration system to remove arsenic from your drinking water is none other than a Reverse Osmosis (RO) water filtration system.

Reverse Osmosis, also known as RO, is a process that uses pressure to force water through a special semi-permeable membrane to remove dissolved pollutants. The layer has tiny pores that allow the water molecules to pass through while trapping larger particles like lead, iron, chromium, and arsenic. The best Reverse Osmosis water filtration systems can filter out up 99% of arsenic from water while serving your home with ample amounts of fresh, clean water every day.

But what’s the best Reverse Osmosis Water Filter system to remove arsenic and other harmful chemicals from drinking water? Continue reading to find out.

First of all, why are Reverse Osmosis systems the best water filtration systems for removing arsenic from drinking water?

Good question. The thing is, reverse Osmosis can remove up to 99% of the dissolved salts, particles, organics, and colloids from the feed water. The RO membrane rejects contaminants based on their size and charge. A properly running RO system will likely reject any contaminant that has a molecular weight that is greater than 200. Likewise, the higher the ionic charge of the contaminants, the more likely it will be unable to pass through the RO membrane.

When the feedwater enters the RO membrane under pressure, the water molecules pass through the membrane, and the salts and other contaminants are blocked and discharged through the reject stream (AKA, the concentrate or brine stream). The wastewater can then get washed down the drain or the system channels it can back into the feedwater supply for the system to recycle and save water.

RO systems also employ cross filtration instead of standard filtration, where the filter media trap the contaminants. With cross filtration, the solution passes through the filter, or crosses it, with two outlets. The filtered water goes one way, and the contaminated water goes another way. Cross filtration helps to avoid the buildup of contaminants by allowing the water to wash away the contaminant buildup while allowing enough turbulence to keep the membrane surface clean.

Apart from providing clean, great-tasting water to drink and cook with, RO systems are also energy- and cost-effective. The RO filtration process uses no electricity, and the system itself can produce high-quality water for pennies per gallon. Not to mention the convenience of being able to access it right at your kitchen tap.

Last but certainly not least, the best RO water filtration systems are quite easy to maintain and require no chemicals. All you have to do is swap out the filters and membranes according to your system’s manual. Better yet, you only need to replace most of the filters every six to 12 months, and replace the RO membrane every two to three years, depending on the water quality in your area and the volume of water the system supplies to your home.

And the best water filtration system to remove arsenic and toxic chemicals from water is the Springwell Reverse Osmosis Water Filtration System (SWRO).

The SWRO filtration system is the perfect solution for filtering out dangerous chemicals and heavy metals from your drinking water. It is a compact Point-of-Entry (POE) system that can fit perfectly under almost any kitchen sink. It takes up the space of a gallon jug, but if it cannot fit under your kitchen sink, you can install it against a sidewall.

The best RO systems offer targeted filtration, which means they can target different kinds of contaminants using various filters. While some filtering systems only contain one type of filter, the SWRO unit offers a variety. This powerful system uses a targeted 4-stage filtration process to remove the following contaminants from tap water:

Lead Iron Pesticides
Mercury Aluminum Herbicides
Fluoride Chlorine Chlorine Byproducts
Arsenic Chloramine And more…

During Stage 1 (Sediment Filtration), the system removes all the sediment, dirt, sand, and other large particles that are present in your drinking water. In Stage 2 (Carbon Filtration), it uses carbon filtration to remove rust, pipe residue, chlorine, chloramine, herbicides, pesticides, and others. In the Reverse Osmosis stage (Stage 3), it uses Reverse Osmosis to filter out heavy metals such as lead, aluminum, iron, and mercury, as well as chemicals like arsenic, fluoride, and more. The last stage, Carbon Filtration, finalizes the cleaning phase and removes any addition contaminants that occurred as a result of the three previous steps.

Another remarkable feature of the SWRO water filtration system is its unbelievable water output. This model provides 75 gallons of fresh, clean water per day, adequately serving a good size household.

In terms of maintenance, you must replace the sediment filter every six months, the carbon filter every six months, and the RO membrane every 24 months. To sweeten the deal, this model comes with a lifetime warranty against defects!


There you have it: the best water filtration system to remove arsenic and other toxic chemicals and metals from water. The Springwell Reverse Osmosis Water Filtration System (SWRO) is a robust and cost-effective system that can make your home much safer and more peaceful by removing some of the most toxic chemicals and metal in your water.
