Can Water Filters Remove Pesticides?

Pesticides can eliminate or control weeds, insects, rodents, and more. These chemicals also increase crop yields.

Pesticides from farms and other agricultural activities often end up in rivers, lakes, and groundwater, eventually contaminating our drinking water.

Short Answer

Yes, water filters can remove pesticides. Pesticides are best absorbed by activated carbon. These filters absorb contaminants like sponges as tap water passes through them. Carbon block water filters remove pesticides, THMs like chloroform, organic chemicals, and many VOCs.

Tap water is safe to drink after being filtered for pesticides and herbicides. Filters prevent these chemicals from entering the pipes. The Big Berkey Countertop Filter, Clearly Filtered Pitcher, and Berkey Water Filter remove 99.9% of glyphosate from tap water. Depending on the filter model, PUR filters remove disinfection chemicals, industrial pollutants, pesticides, heavy metals, DBPs, particulates, herbicides, and pharmaceuticals.

EPA-approved activated carbon filtration removes almost all herbicides, pesticides, and inorganic contaminants from water. It’s the best way to purify tap water.

As a technician, I’ve seen water filters filter pesticides and other contaminants from tap water. One of my customers worried about pesticides in tap water because they lived near farms. An activated carbon filter improved their water’s taste. The filter gave them confidence that they were drinking clean water.

Activated Carbon

Atrazine and 2,4-D weed killers can be filtered out of drinking water by activated carbon filters.

Because of its many small pores, activated carbon is unlike other filter materials. This can boost a water filter’s effectiveness, especially with other contaminant removal technologies.

All types of activated carbon filter contaminants from air or water. Wood, coal, peat, coconut shells, and other carbonaceous materials are used to make them.

Steam and high temperatures without oxygen create porous carbon with many small, activated pores. Crushing this type of carbon into granular activated carbon or blocks increases its surface area, allowing it to adsorb harmful chemicals.

Reverse Osmosis

Pesticides in your drinking water can harm you and your family if you live in an agricultural area. There are several ways to remove these harmful chemicals from the supply chain.

Reverse osmosis is a proven method for removing these chemicals from water. Pressure forces molecules through semi-permeable membranes that let water pass but not contaminants.

RO removes most drinking water-introduced dissolved organic pollutants. It also removes organochlorines and acetanilides from your water, which can be harmful.

RO systems clean water in several steps before it reaches the tap. The first filter filters your liquid through a semi-permeable membrane to separate large particles from smaller ones, then reduces dissolved solids and adds beneficial minerals.


NSF-certified water filters have undergone rigorous testing and evaluation. This ensures your filter is safe, reliable, and performs as promised.

In addition to pesticides, NSF-certified water filters reduce other pollutants. VOCs, chlorine, and lead are included. (volatile organic compounds).

Choose an NSF-certified water filter for peace of mind and family safety. These filters are also compatible with many water fixtures.

NSF International is a nonprofit that develops and enforces product standards. They ensure water quality and food safety products are safe and effective.


Filters purify drinking water more sustainably. They remove chlorine, pesticides, and other harmful substances from tap water.

They reduce energy costs too. Dishwashers and refrigerators run more efficiently without sediment.

They can also prevent plastic bottle pollution. Most of the 300 million tons of bottles made yearly end up in landfills.

Bottled water is more expensive than filters. Filters save gas, electricity, and the environment by reducing water transport.
