DIY Solutions for Removing Heavy Metals from Your Drinking Water

Curious to find out how to tackle this alarming concern without draining your bank account on costly water filtering systems? Maybe you’ve considered opting for bottled water, but you’re also aware of its environmental implications. Don’t worry, there’s an array of feasible DIY solutions you can adopt to markedly decrease the concentration of heavy metals in your household’s water supply. If you want to know how, let’s explore some practical techniques right below:

Sedimentation and Filtration

Here’s an easy-peasy approach you can use: Sedimentation. This technique aids in eradicating suspended particles such as dust, sand, clay, or rust from the water. The trick is to let the water rest, undisturbed, for a while, typically about 24 hours. This time allows the weightier particles to settle down to the bottom, leaving the clearer water layer on top.

Next, you’d want to gently pour off this transparent layer, which can then be filtered using earth-given filter materials like sand or activated charcoal.

Let’s now dive into how to create an elemental sand filter right in the comfort of your home:

  1. Make a start with a sizable container or bucket. Near the base, drill a petite hole. Once you have done that, position a piece of cheesecloth or a coffee filter over the recently created hole.
  2. Fill the container with layers of sand, grass, gravel, and activated charcoal in descending order (largest particles at the bottom).
  3. Pour the stored drinking water through this filtration system. Collect the filtered water and repeat the process if necessary to further improve clarity.

Do bear in mind, though, while these procedures can help purge many impurities and heavy metals such as arsenic, they might not be as adept when it comes to tackling certain other metals, like lead or mercury. Moreover, the efficiency of these methods shoots up when paired with others like reverse osmosis or distillation, ultimately yielding superior results.

Activated Carbon Filters

Activated carbon filters are an excellent way to remove heavy metals from your drinking water at home. They work by adsorption- a process where heavy metal ions are attracted and bind themselves to the activated carbon surface. These filters can either be used standalone as pitcher filters or installed on taps/faucets for constant filtering of your drinking water supply. You can learn more about these activated carbon filters at this link.

To make an activated carbon filter at home:

  1. Gather raw activated charcoal from aquarium/filter supply stores or create your own from hardwood materials by burning them in a low-oxygen environment until they turn black and brittle.
  2. Rinse the charcoal with clean water to remove any dust and contaminants present on its surface.
  3. Create a layered filtration system similar to that described under “Sedimentation and Filtration.” However, include more substantial layers of activated charcoal in between sand/grass/gravel layers for better efficiency.

Reverse Osmosis (RO)

Reverse Osmosis (RO) filters are widely popular for their ability to remove a variety of contaminants, including heavy metals. RO systems force water through a semipermeable membrane at high pressure, leaving behind impurities like heavy metals and dissolved salts. Although more expensive and complicated to install in comparison to the previous methods, Reverse Osmosis filters are highly effective at producing safe drinking water.

Now, you might fancy the idea of setting up your DIY Reverse Osmosis filter. Be mindful though, this venture calls for some specific equipment and a dash of plumbing expertise to guarantee its correct assembly and installation. Countless online tutorials and kits are at your disposal that can navigate you through this intricate task, if you reckon you’re up to the challenge.

Ion Exchange Resins

Ion exchange resins work by replacing the heavy metal ions present in water with other less harmful ions such as sodium or hydrogen. The ion exchange process can effectively eliminate a wide range of heavy metals from your drinking water with high efficiency. To create an ion-exchange filter at home:

  1. Purchase ion exchange resin beads or cartridges from specialist stores or online marketplaces (make sure they specifically target heavy metal ions).
  2. Add these beads/resin cartridges to your existing filtration system (sand/activated carbon), ideally after the activated carbon stage.

Alternatively, create a standalone filter by placing the resin within a plastic bottle: make holes near the bottom for filtered water flow and add layers of activated carbon/sand/grass on top of the resins as additional filtration stages.


Preserving a safe and pure water supply in your home is vital in bolstering good health. Yes, there is a plethora of professional water filtration systems in the marketplace designed to combat heavy metal infiltration. But don’t overlook the wealth of budget-friendly DIY alternatives that could deliver equally effective outcomes.

Applying techniques such as sedimentation, activated carbon filtration, reverse osmosis, ion exchange resins–or a harmonious mix of these–you can drink with confidence. The peace of mind comes in knowing that you and your family are sipping on cleaner, and more importantly, safer water.
