Discover the Best Arsenic Water Filter Solutions for Pure and Safe Drinking Water

Your home should be a place of tranquility, relaxation, and safety. No matter what kind of challenges you face in the outside world, going home should be your safe haven—a place where no dangers exist.

You’re probably sitting there thinking that your home cannot be safer than it already is. With its locked doors, shut-tight windows, and fortified gates, there’s really no reason not to feel safe. However, there is one intruder that can get past this.

We’re not talking about robbers or anything of the sort. This intruder is something that you welcome into your home with open arms, and it comes in the form of water. If not paid proper attention, the water that goes straight into your faucet may pose thousands of risks to you and your family.

To prevent this from happening, you need a strong filter, and that’s what we’re here to talk about. We’ll let you know about the best water filter for arsenic to bring you one step closer to getting the purest and healthiest drinking water.

What Happens If You Drink Arsenic-Contaminated Water?

What are the dangers of drinking water contaminated by arsenic? How bad can it really be? How does that happen? Is there any way you can prevent that?

Where Is It from?

First of all, arsenic is used in all kinds of pesticides and even in manufacturing alloy and lead products like batteries. Now, imagine if something as strong as that were to be ingested by your family. It can lead to high levels of toxicity that your body won’t be able to suppress it. The bad news is, there is a strong possibility for this to happen.

Arsenic is either organic or inorganic. The latter is quite more dangerous, as it contains more harmful chemicals, but that doesn’t mean that organic arsenic is in any way safer.

To make matters worse, arsenic is found in groundwater and in multiple water sources like lakes, dams, or water reservoirs. This makes it quite easy for this toxic chemical to reach your home.

What Are Its Effects?

Regular consumption of arsenic, even in small doses, may result in skin irritation, compromised nervous system, respiratory problems, weakened vital organs, especially the heart. It also may eventually lead to death.

As the demand for fighting these hazards arise, the development of water-filtering systems that can extract this chemical from your drinking water has been promising, as well. In our quest to make your home a safer place, we found the following products that may help with that matter.

A typical day for us is spent looking for ways in how we can guarantee that you get to choose from the best of the best when it comes to home improvement items. Today, we went around looking for the best filter for arsenic, and here’s what we found.

The Ultimate Guide to Choosing the Best Arsenic Water Filter for Your Home

Choosing a water filtration system is easy if you know what you’re looking for. Still, we understand that it’s quite challenging to take note of all the considerations you may need when finding the best product.

To help you out, we’ve prepared a quick list of the things you may want to keep in mind before installing a water filtration system in your home.

  • Needed Volume of Filtered Water

First, you need to consider the volume of filtered water that you or your family may need. This can be subdivided into a type of filtration system or its output rate.

For example, if you have a big family, chances are you’re going to need more filtered water. This makes the whole-house system a great choice. Alternatively, you can also go for models that have a fast water output rate.

On the other hand, if you live on your own, a tank or tankless option with a low water output rate will do.

  • Filtration Power

Just because it’s a water filtration system does not mean you get the same filtration power with every model. Some filters can remove 95% of contaminants, while others can go for up to 99.99%.

Take note of the mode’s filtration power to understand how much cleaner and healthier your water gets.

  • Installation Space

The area where you’d install your unit is also quite important. For example, a small kitchen will not benefit from tank models compared to under-sink and tankless filter systems.

Consider your installation space before choosing a water filtration system.

Water Filter to Remove Arsenic FAQs:

How does arsenic get mixed with your tap water?

Nature produces arsenic, as this is a compound found in rocks and soil. Aside from that, industrial processes and the use of arsenic in pesticides eventually lead to a deposit of this compound in groundwater.
Unfortunately, sooner or later, this arsenic deposit reaches our water sources. This is the reason why installing a water filtration system for our home is essential.

Why is it difficult to track arsenic in your water?

The problem is that arsenic is tasteless, odorless, and colorless. This makes it extremely difficult to notice whether our water is contaminated. Multiple tests provided by various organizations is one of the few ways in which we can identify whether our water is arsenic-free.

How is arsenic removed from water?

One of the most popular methods in removing arsenic from water is through a process called reverse osmosis. This is done by using multiple filters to remove the impurities from the water, and that is why water filtration systems are important.


After careful consideration of all the features of each product we listed above, we finally have a verdict. If you ask us, the Frizzlife Under-Sink Water Filter System is the best water filter for arsenic.

Aside from giving you arsenic-free water, its under-sink design also helps you save lots of space in your kitchen. However, what really tilted our decision in Frizzlife’s favor is the fact that they considered the plastic waste we carelessly discard when changing filters. Frizzlife not only makes your life healthier but our environment, as well.

On the other hand, if you want to take it to the next level, give the Express Water Whole House Water Filter a try. It definitely made quite an impression on us, with its whole-house integration of their system.
