The PFAS chemicals have been under critical scrutiny for their devastating nature in the past few years. In the chemical process industries, these are commonly used chemicals.
The PFAS category includes PFOS and PFOA. They’re found in both surface & groundwater. Even PFAS is hard to remove from water, microscopic particles of the compounds can be detected in the drinking water.
At first, I was curious about does a Zero water filter removes PFAS? And after using the filter, I understood that:
Not all Zero water filters remove PFAS. So, if you want to remove PFAS, you should go with the RO, and Activated Carbon based Zero water filters because it removes PFAS up to 99.8%.
Does Zero Water Filter Remove PFAS?
There is no exact answer for this question because I have used various types of Zero water filters, and some of them were able to remove PFAS, but the maximum was not. So it depends on your chosen filter.
As PFAS contamination is still a relatively great finding, none of the common filters sold in shops have been verified or certified to remove PFAS. Simple charcoal filters (such as Brita and Pur) are not tested for PFAS.
Even the most modern filters, like those manufactured by ZeroWater, are incapable of removing PFAS. PFAS cannot be removed by even the most modern filters, like those produced by ZeroWater. Several reverse osmosis processes can reduce PFAS. However, this varies widely amongst units, and most methods have yet to be evaluated.
Now I want to share a list with you to understand which filter removes PFAS and does not. So let’s see:
|Clearly Filtered Pitcher||99.5%|
|Clearly filtered under sink||99.8%|
|Clearly filtered fridge||99.8%|
Does Zero Water Filter Remove PFOA?
No, according to my experience, Zero water filters don’t remove PFOA. However, check the body of your Zero water filter. If the NSF international provides a certification mark, it will remove PFOA. Otherwise, a Zero water filter is not able to remove PFOA.
Does Zero Water Filter Remove Chemicals?
Yes, Zero water filters remove chemicals from the water. In addition, a Zero water filter removes any chemical, metal, or chlorinated smell from the water, ensuring that it is not only hygienic but also tasty.
The Zero Water filter eliminates chlorine, sediments, pollutants, metals, and protons. It also guarantees that the water is free of lead, cadmium, tri, oxyhydroxides, hydrogen sulfide, & chlorine, thanks to its four different filtration systems.
As a result, you may have peace of mind knowing that both you & your family are drinking fresh and pure water at any time by filtering out all of these components, chemicals from the water.
The ZeroWater filter is less expensive than the other filters and may provide great value for money. It also filters your water to eliminate up to 99 percent of pollutants and sediments.
Which Whole House Water Filters Remove PFAS and PFOA?
For removing PFAS and PFOA, I always recommend the Aquasana Rhino Whole House Water Filter. So, here I will add some of the pros and cons of this water filter to understand it better. So let’s see:
Aquasana Whole House Water Filter
This is the greatest whole-house PFOA and PFAS filter for purifying water throughout your entire household. This filtration process uses innovative technology to be last up to 10 years and clean up to one million liters of water. And the best part is, it can clean Sediment and Chlorine up to 97%.
This filtration process may be connected to the main water supply. It purifies and provides safe drinking water from each and every source in your home, guaranteeing that you may shower, bath, cook, clean, and consume water that is PFAS-free.
In addition, the whole family will be protected from dangerous pollutants and PFAS and PFOS chemicals in this manner.

Which Water Treatment Process Removes PFAS and PFOA from Water?
If you want to eliminate PFOA and PFAS from your tap water, several water treatment methods can help. So, here I will discuss some of the water treatment processes, which I follow to remove PFAS and PFOA from water, and it works really well. So let’s see:
Activated Carbon Filters
Activated carbon filters, such as granular Carbon and solid carbon blocks cartridges, are very efficient at eliminating PFOA and PFOS from drinking water supplies in the home. The activated carbon filter is the most researched water treatment choice to make if you’re coping with PFAS pollution in the U.s, as per the EPA. Chlorine, mercury, PFOA, and PFAS are among the pollutants that a granular activated charcoal water filter can adsorb. Activated Carbon is an excellent filtration choice because it is very porous and has a huge surface area, capturing larger pollutants inside the filter pores & permitting only micro water particles to get through.
As per an EPA scientist, granulated activated charcoal can always be completely effective for a short time – and it depends on various aspects, including water temperature and pressure, the thickness of the carbon beds, and the forms of PFAS and PEOA that need to be eliminated. There are a variety of GAC treatment techniques available. However, a GAC filter is often used in an entire-house application for being well and municipal water purification.
Systems for Ion Exchange
Ion exchange can be another water treatment option for eliminating PFAS from tap water. The ion exchange treatment consists of a tube filled with anion exchange resins, usually comprised of refractory hydrocarbons.
Anionic polymers & cationic resin are the 2 kinds of ion exchange polymers available. Because cationic polymers are considered impolite, they are better at eliminating positively charged pollutants, whereas anionic polymers are effective at eliminating negatively charged contaminants because they are positively charged.
Both resins beds attract certain pollutants, which cling to their surface and are impossible to flow through the container with the water particles. Because PFOS and PEOA are usually changing negatively, anionic resins are indeed the best option for eliminating them. Although this method has a larger capacity than active carbon water purification, it has a higher initial cost. However, The ion exchange service, like the activated carcole water filter, is very efficient at eliminating PFAS and PFOA from drinking water.
The reverse osmosis filter cartridge is often among the most comprehensive and versatile water filters widely available. Water is forced through a moderate-permeable membrane with tiny pores measuring roughly 0.0001 millimeters in size at the time of reverse osmosis procedures. While PFAS come in various sizes, they are typically significantly larger than the porous membrane. Therefore, they cannot be filtered through with the water particles.
The reverse osmosis filters may often lower PFOA & PFAS levels by up to 90%. In addition, phthalates and hundreds of many other trace impurities are thrown down at the time of reverse osmosis procedures, ensuring that only pure water reaches your faucet.
Does a Zero water filter remove PFAS? So, in my experience, no, it doesn’t remove PFAS but doesn’t forget to check the certification mark by the NSF international. If there is a certification mark, count your Zero water filter as safe and PFAS removable.
If there is no certification mark, it won’t remove PFAS.
However, be careful when choosing something related to your regular drinkable water because a little risky thing can cause a big health hazard. So, don’t forget to take care of your health and stay safe!
