What We Like:

  • Installing the system requires little to no experience, thanks to a set of inlets and outlets compatible with most plumbing systems out there.
  • The filters come with their own instructions and hardware that make the installation decently straightforward.
  • We found exceptional improvement in arsenic content as well as other contaminants when compared to unfiltered water.
  • It doesn’t hinder pressure or flow in the water, providing maximum quality filtering while keeping the water flow steady.

What We Didn’t Like:

  • Because the filters are large and bulky, setting up in small households could be somewhat complicated.

 


3.InvisiClean 5-Stage Filter Pitcher

A whole-house filter is not always the best idea. In some cases, you only need to clean a few ounces of water now and then. In that case, investing in an extensive system is not the best idea, so a filter pitcher comes as the best choice.

This filter offers a total capacity of 8 cups of water. You can clean that much at once, getting rid of everything that could potentially harmful, going from metals like aluminum, nickel, zinc, manganese to harmful elements like mercury, fluoride, and most importantly, arsenic.InvisiClean

The combination of a coarse filter, ion-exchange filter, a slow distribution filter, a multi-layer carbon filter, a non-woven filter makes this possible. There’s no harmful sediment, chemical, metal, or mineral capable of going through this system.

At a low cost, you also get a small filter. The convenience it offers is other-worldly. You can bring it around as a travel or camping filter if necessary, saving you a lot of space while cleaning your water wherever you go.

Using it is also a piece of cake. You get an easy-to-fill lid that lets you pour water inside even with the lid on. And when it comes to pouring, it has the standard crevice for easy consumption.

Cleaning it and storing it is also a piece of cake. It comes with different parts that last a lifetime while ensuring easy disassembling. Even if you’re continually using the pitcher, the product will handle the strain and use it over time.

Despite its unbeatable convenience and filtering capacity, the system wears out fast. In contrast with other models, this one needs to be changed continuously with a TDS meter to prevent the water from getting over 10 PPM. As long as you do that, the filter will clean up your water effectively.

What We Like:

  • The pitcher design increases the portability, storage capacity, and convenience you get from the filter.
  • After several tries, we found the water to come up super-clean out of the filter despite its seemingly small design.
  • It comes at an incredible price considering how practical and effective it is at filtering water from the faucet.
  • We found it the easiest-to-use filter in the whole list as it doesn’t require any installation type.

What We Didn’t Like:

  • Being smaller than its competitors makes this filter a lot less durable, usually demanding change within the first 6 months of use.

 


4.AdEdge AD2X10C Inline Arsenic Reduction Filter

An under-sink filter to get rid of arsenic is also a valuable piece to go for. The AdEdge AD2X10C will go under your kitchen sink to provide on-demand filtered water that doesn’t have a single particle of arsenic.

It does such excellent work, thanks to the A33 arsenic media. This is a high-quality iron oxide media that removes both +3 and +5 types of arsenic, preventing it from reaching your organism. In the process of removing the arsenic, the filter avoids oxidation so that you can drink clean and healthy water.AdEdge-AD2X10C

There’s another advantage to consider from this filter: it has an in-line design. This design saves you a lot of effort into the installation. But most importantly, it takes little to no space under the sink. If you want to pair it up with other filters from AdEdge, then that’s totally possible.

Types of Arsenic in Water

Arsenic is not like any other contaminant that appears in the water, and you can identify it right away. Instead, arsenic comes in various levels or types. Depending on the one that appears in your water, you can figure out whether the filter you’re choosing can remove the arsenic or not.

The two types you’ll find are organic and inorganic arsenic. Here’s how they differ:

Organic Arsenic

This is the natural type of arsenic found on seafood and different kinds of vegetation. As humans, we can’t process arsenic in our bodies like we do other metals. Luckily, organic arsenic is not harmful, and it is pretty rare to find large quantities of it in the same place. This type of arsenic is usually not necessary to filter.

Inorganic Arsenic

This type of arsenic is produced by chemical reactions from industrial processes on soil and rock. Processes like mining and smelting tend to produce this arsenic, which can adhere to the soil, air, and water. And that’s when it starts to become dangerous.

We can find the arsenite or AS+3 (III) and the arsenate or AS+5 (V) within inorganic arsenic. These arsenic sub-types can cause different kinds of damage to the body in the short and long term. Not everyone suffers from arsenic effects, but it is still worth filtering away from water and air.

If you want to prevent inorganic arsenic from getting into your body, nothing else will be as helpful as the best arsenic removal system. But first, you have to make sure that water is indeed reaching your home with arsenic.

Testing for Arsenic: Harmful Levels

When arsenic was first discovered as a side effect of industrial and commercial processes, testing its different levels wasn’t easy. Luckily, the methods for measuring changed and improved over time. Today, you only need an arsenic kit to test.

These kits usually come with a bottle where you need to pour the water to test. A small strip goes into the water, causing a chemical reaction within the arsenic compounds and zinc that produces arsine gas. This gas is then measured to find out how much arsenic is within the water.

It gives the result via PPB (parts per billion). It is known that even 3 ppb of arsenic in a small bottle of water can cause severe health damage.

Another way to calculate arsenic (by measuring metal in the water) is to use a TDS meter. It refers to a Total Dissolved Solids meter that checks the water’s acidity and conductivity level, telling you an approximate of the particles via PPM (particles per million).

In this case, levels over 5 ppm can be extremely dangerous (if there’s arsenic on the water).

Health Affects of Arsenic in Drinking Water

Now that you have a better idea of measuring arsenic, you may be thinking about what side affects it may cause. Well, you’d be surprised by how harmful it can be.
Some of the different harmful affects of drinking water with arsenic include:

• Stomach pain
• Diarrhea
• Vomiting
• Nausea
• Skin discoloration
• Limb numbness
• Blindness
• Partial Paralysis
• Cancer

These are all short and long-term side effects possible if you ingest too much water with arsenic content.

Can you filter arsenic out of water?

Yes, it is totally possible. However, you will need to use one of the 3 main types of filters to remove arsenic from your water.

Reverse Osmosis (RO) Filters

When it comes to cost per gallon, reverse osmosis (RO) is the most affordable way to filter arsenic out of water. Apart from being inexpensive, reverse osmosis makes it possible to remove everything from iron, lead, and chromium to arsenic from the water. It can remove up to 95% of all arsenic (+3 and +5).

Most reverse osmosis filters, however, are used as an under-sink or faucet-dependent system. In case you need something that filters a lot of water or can handle an entire house water delivery system, then reverse osmosis won’t be your best idea.

Anionic Exchange (Resin) Filters

While RO filters are excellent for reducing the amount of arsenic in the water, they don’t perform as fast as an anionic exchange filter (or resin bed). These resin filters are the most popular because of their capacity to rapidly filter out water, getting rid of metals like iron and manganese while reducing arsenic exponentially.

An anionic exchange filter is also more popular, mainly because these systems come with whole-house designs. Meaning they can filter out water in massive quantities without affecting the quality of the filtering process.

Iron-Oxide Filters

For people who want to increase their filtering capacity, an iron-oxide filter comes like a charm. These excellent filters lower arsenic levels exponentially by using a similar mechanism to the carbon filter. It is made of a specific piece of media made of iron-oxide material capable of trapping metals like arsenic.

The advantage of iron-oxide filters is that they come in both in-line and whole-house designs. You can decide which type to use depending on your needs. Yet, they’re also excellent arsenic-removal systems, typically used as enhancements for other filters or standalone for rapid filtering capacity.

How to Filter Arsenic from Well Water?

The best way to remove arsenic from well water is to use a filtration system like reverse osmosis, iron-oxide, or anionic exchange to filter out – as we explained before.

It is common to find people who affirm that boiling or heating the water removes arsenic. But that’s not true. As a metal, arsenic is not susceptible to heat. Instead, heat boils down water leaving the arsenic behind. By boiling or heating the water, you are increasing the amount of arsenic.

Filtering the entire well is pretty difficult to impossible (unless you count with tons of money to spend). Generally, it is recommended to install the filters on faucets or lines that connect with the well. If you don’t have the well connected to plumbing lines, then distillation and ultra-filtration are also filtering methods worth trying.

Other less practical but still worth-mentioning methods include lime and coagulants, as well as precipitation. These methods are less effective but still worth noting as cheap and accessible options.

How Much Arsenic Is Safe In Well Water?

Whether it is on a well or any other water source, arsenic should be less than 10 micrograms per liter. To make it easier to understand, you should find no more than 10 ppb (parts per billion) of arsenic in the water.

After using a water tester for arsenic, you should make sure the well has less arsenic than 10 ppb. Otherwise, it will be necessary to filter or re-filter the water for consumption (mostly drinking).

Frequently Asked Questions (FAQs)

By now, you should be aware of a thing or two about the best arsenic removal system. But there’s a chance you still have a few doubts about them. Below, we answer some of the common questions, probably including one of your doubts.

How common is arsenic in water?

The answer depends on the place and closeness to industrial processes. Generally, however, arsenic is found on at least 30% of all wells and water sources worldwide. Millions up to billions of people around the world are in contact with arsenic-filled water. In the US alone, 40% of all dug wells contain arsenic.

What is a natural way to remove arsenic from water?

Two natural methods are easy to repeat: coagulation and adsorption. Coagulation is about using metal salts and lime to form flocs that trap the arsenic in the water. Adsorption is about using a solid material that attracts arsenic, like electrostatic metal hydroxide.

Does RO remove arsenic from water?

Yes, reverse osmosis (RO) is one of the best ways to remove arsenic from different water sources. Not only it removes arsenic but many other contaminants and metals, going from manganese and iron to lead and chromium, as well as a wide array of chemicals like sodium and chloride.

What does arsenic in water smell like?

There’s no way to detect arsenic via smell. When arsenic is in incredibly high quantities, it could be dangerous even to smell it. According to experts, arsenic smells similar to metal, so that could give you a better idea. But in small quantities, as you can find it on most water sources, it has no smell or color.

Conclusion

If you want to prevent all the major dangers of drinking arsenic causes, nothing will help you more than having the best arsenic removal system at home.
