5 Best Water Filter For PFAS, PFOA & PFOS Chemicals [2023]

Let us explain what are PFAS, PFOA & PFOS chemicals before we introduce you to the 5 best water filters for PFAS, PFOA & PFOS.

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS in short) are a group of man-made chemicals that have been widely used in products like non-stick cookware, water-resistant clothing, microwave-safe popcorn bags, pizza boxes, candy wrappers, etc.

According to the Environmental Protection Agency ( EPA), there are thousands of different kinds of chemicals that fall under the PFAS group. Among those chemicals PFOA (Perfluorooctanoic Acid) and PFOS (Perfluorooctane Sulfonic Acid) are the most widely used chemicals.

Chemicals that fall under the PFAS group are known as “Forever Chemicals” because the typical environmental condition can not break the molecular structure of PFAS chemicals. Evidence has shown that the water resources of (at least) 29 states have been contaminated with PFAS chemicals. You can learn more about PFAS chemicals here at the official webpage of EPA.

What are the Dangers Of PFAS, PFOA & PFOS In Drinking Water?

Scientists and the environmental working group have warned that the widespread presence of PFAS, PFOA & PFOS chemicals are now being found in people, wildlife, in natural water sources. Studies have found that PFAS pollution affects the liver and thyroid. It causes impaired immune function, thyroid diseases, high cholesterol, obesity, hormone suppression, and cancer. Toxic Pfas are extremely harmful to pregnant women because it affects reproductive and developmental health and causes low birth weight in babies.

Unfortunately, EPA has yet not passed any regulation that will compel water suppliers to filter PFAS chemicals at their water-filtration plant before sending them out to your homes. So, it has fallen on an individual’s shoulder to protect himself and his family from these fatal chemicals.

Evidence From A PFAS Investigation Done By The New Hampshire Department Of Environmental Services

What kind of water filter is most effective against PFAS, PFOA, and PFOS chemicals?

Based on the investigation conducted by the New Hampshire Department Of Environmental Services, Reverse Osmosis and Carbon-based water filters are effective against PFAS chemicals. Since PFOA and PFOS also belong to the PFAS group, they can be filtered using reverse osmosis or carbon-based water filters.

Body Design and Installation: Since it’s a tankless water filter, it’s pretty compact and lightweight. You can install it under a sink / over a counter, basically anywhere you like. It weighs 32 pounds and has a body dimension of 18.07 x 5.52 x 17.52 inches. Waterdrop G3 comes with a smart faucet and has a TDS monitoring panel on top of it. The panels show TDS ( total dissolved solids ) reading along with other vital information.

The installation process of G3 is fairly simple. Waterdrop says, their intelligently designed water filtration system can be installed in under 30 minutes. But that’s just a marketing stunt. For an average joe, it will take about 2 hours.

Due to its tankless design, Waterdrop G3 prevents secondary pollution. Secondary pollution occurs when freshwater gets contaminated within the water tank itself. It’s a common problem that has been seen in many tank-type water filters. Since G3 doesn’t store filtered water, there’s no chance of clean water getting polluted inside the machine. To us, it is one of the biggest advantages of Waterdrop G3.

Water Supply Rate: According to the water supply rate, Waterdrop G3 is a quite powerful reverse osmosis water filter. It provides clean, fresh, and pure water at a speed of 400 gallons per day. It can fill a cup in about 12 seconds. Since we recommend using it only for drinking and cooking water, 400 gallons per day is more than you will ever need. A quick FYI, an average person needs only 1.5-2 gallons of drinking and cooking water per day.

Do the math, Waterdrop g3 can provide enough fresh water for the largest family you can think of. It can meet the water demand of small companies, restaurants, and motels.

Reverse Osmosis Waste Water Ratio: On a plus, point, Waterdrop G3 has a drain ratio of 1:1. So, in total it needs 2 gallons of water to produce 1-gallon freshwater. For an RO system that has a 400 GPD water flow rate, we are quite impressed with the drain ratio.

Just so know, traditional RO water filters need 3, even 4 litter of water to produce 1 liter of fresh drinking water. Compared to them, G3 is much more efficient and will help you reduce your water bills.

Water Filtration Process: Waterdrop G3 uses 3 composite filters. The first composite filter is 3 layers of paper + activated carbon filter. The 2nd composite filter is a 3-layered RO membrane filter and the last composite filter is a post-activated carbon block filter.

Together they provide a 7-stage deepwater filtration process with an accuracy of 0.001 um. As we have stated earlier, carbon filters and RO filters are most effective against PFAS, PFOS, and PFOA chemicals. And, the waterdrop G3 uses both of them. So, you can be certain that purified water by G3 will be healthy, safe, and tasty. Moreover, the waterdrop G3 filters out heavy metals and lowers TDS as well.

Maintainance: Composite filters used in G3 have a pretty decent lifespan and replacing them is as easy as it can get. You need to change those composite filters every 5-6 months.

Waterdrop G3 comes with a smart faucet that has an led indicator light. g3 keeps track of the filter usage and The light indicates when to replace the composite filters. They are fairly cheap and take only 3 seconds to replace.

NSF Certification: Waterdrop G3 has Nsf 58 and NSF 372 certification. Nsf 58 certifies that it can successfully lower TDS by 90%. Nsf 372 certifies that it’s a lead-free safe product for the consumers.

4. Aquatru Countertop Water Filtration System: Best Installation-Free Countertop Water Filter For PFAS,PFOA & PFOS

The next water filter we recommend is the AquaTru countertop water filtration system. It provides 4 stages of ultra reverse osmosis technology. Since it’s a countertop water filter and stores purified water in a small tank, it doesn’t need any plumbing or installation. It’s a plug-and-play type water filter, suitable for small families living in apartments as well as mobile homes, RVs, etc. It is also a great option for renters who are prohibited to make any plumbing modifications by the rent agreement.

How well is The AquaTru water filter designed? For a water filter that has 2 removable side tanks, we would say AquaTru is pretty well designed. Due to its reduced footprint, it can Be put even on the smallest countertop. It has body dimensions of 14 * 12* 14 inches and weighs about 23 pounds.

Aquatru uses 3 composite filters to purify tap water. this pitcher-style filter has a “digital display screen” that turns on during the water filtration process. It shows estimated water processing time and other important notifications.

How much water can Aquatru Water filter purify in an hour? Of those 2 tanks, one is for unfiltered tap water and the other one is for freshwater. The tap water tank is slightly bigger than the fresh water tank.

The tap water tank can hold 1 gallon ( 16 cups) of water and it takes 12-15 minutes for AquaTru to purify it. After the process, you will get about 10 cups of water. Based on the water supply rate it’s not really a quick one. That’s the reason why we recommend it for smaller families.

What is the drain water to pure water ratio of Aquatru? The wastewater ratio of Aquatru is 1: 1.6. This means, that from 2.6 liters of city water it can produce 1 liter of pure drinking water.

How does Aquatru purify tap water? AquaTru uses 3 composite filters and a 4-stage cleaning process to remove toxic chemicals from your tap water.

The first filter is a pre-activated carbon filter that removes particles like sediment, rust, and chlorine.

The second filter is a RO filter that removes harmful inorganic chemicals like peas, Arsenic, uranium & nitrates.

The last composite filter is the VOC filter. It’s a coconut block carbon filter that clears out organic compounds and prescription drug residues. It also improves the taste of your drinking water.

Does Aquatru require maintenance? Based on the number of impurities present in your tap water, the Aquatru filter can last for 600-1200 gallons. Based on a rough calculation, you will need to change the filters every 6-9 months.

NSF Certification: After a long & rigorous test, Aquatru managed to get Nsf 53,58 and 42 certifications. AquaTru can remove Lead (by 99.1%), Chromium (by 97.2%), Copper (by 95.2%), Fluoride (by 93.5%), Radium (by 96.4%) , Chlorine ( by 96.6%) along with other 1000+ contaminants.

Unless you are a skilled craftsman, we don’t recommend you install it. iSpring is a very popular brand in the USA. And if you want to install the system all by yourself, you will find their video tutorials useful.

What is the function of the Booster Pump included with the iSpring-7 water filter? Included booster pump in the package, is a plus point for this water filter. If needed, the electrically operated pump increases the water pressure and pushes it through the RO membrane for a faster water filtration process. People who have low-pressured water at home will find it extremely useful.

Unlike city water, water from natural sources sometimes contains microscopic bacteria and pesticides that get killed during ultraviolet filtration.

How frequently does it require maintenance? Depending on the water usage, the filter cartridges used in ispring -7 will last for 6-12 months.

Does iSpring-7 come with a Warranty? With this unit, you will get a 1-year limited warranty that includes all the parts that come in the package.

How to Remove PFAS From Water? What kind Of Water Filters are Effective Against PFAS, PFOA & PFOS Chemicals?

According to The New Hampshire Department of Environmental Services (NHDES), there are only 2 types of water filters that can effectively remove PFAS contaminants from water.

1) Reverse osmosis water filters

2) Granular activated carbon block water filters

Reverse Osmosis Water Filters: Reverse osmosis filters are the most effective systems for removing toxic perfluoroalkyl substances from water. They do not only filter out Pfas contaminants but also 1000+ contaminants including lead, mercury, arsenic, chlorine, fluoride, viruses, bacteria, etc. Purified water by a good quality RO filter is considered the safest drinking water on Earth.

RO water filters unit uses multiple composite filters such as sediment filter, carbon filter, and membrane filter. All together they filter water in 4-7 stages clearing out every contaminant larger than 0.0001 micrometers.

Since the average size of PFAS particles ranges from 250 to 450 micrometers, an RO system can filter out every PFAS, PFOA, and PFOS chemical from your drinking water.

Although the reverse osmosis filters are 100% effective against PFAS contaminants, they are not the most efficient systems. The only downside of RO water filters is their low water production rate. Generally, an RO filter can produce only 1-gallon of freshwater out of 3-4 gallons of tap water. However, a modern tankless Type RO filter is much more efficient. They can produce 1-liter freshwater out of 2-liter tap water. To prevent water wastage, reverse osmosis filters should only be used in dedicated locations like the kitchen sink, water dispenser, refrigerators dispenser, etc.

Granular activated carbon filters: As the name suggests granular activated carbon filters use carbon blocks to remove contaminants from Water. Most GAC filters use coconut shell carbon to filter PFAS chemicals and improve water taste.

On the bright side, GAC filters can purify hundreds of gallons of water without wasting any of it. But on the downside, GAC filters are not as effective as reverse osmosis filters. Studies have found that a GAC filter can only remove 90%-95% of PFAS contaminants from water. Water filtration accuracy depends on the size of the carbon block filter, lifespan of the carbon block filter, and of course the quality of the supplied water.

Conclusion

The study conducted by The New Hampshire Department of Environmental Services (NHDES) has also found that PFAS chemicals pose a significant health threat when it is found in drinking water. But exposing skin to PFAS contaminated water is not much of a threat.

So, they suggested using reverse osmosis filters to purify drinking/cooking water and a whole house carbon filter to purify all the water that enters the house.

Based on our research, a RO water filter will be most suitable for those who are looking for a budget-friendly short-term solution against PFAS contamination.

And, a whole house carbon water filter for those who want to invest in their good health for a longer period.
