- Updated: December 30, 2024
Summary
Copper in drinking water, while essential in trace amounts, can pose health risks when levels are excessive. Testing water for copper levels is crucial, as it can’t be detected by taste or smell. Legal limits set by the EPA and WHO underscore the importance of filtration. Various water filters, including activated carbon, reverse osmosis, distillers, and ion exchange systems, effectively remove copper. Top brands like Berkey, APEC, Aquasana, and ZeroWater offer reliable solutions. DIY methods like letting water run, using cold water, or creating acid-neutralizing filters can also help reduce copper levels temporarily. Regular maintenance and proper disposal of filters ensure their effectiveness and environmental responsibility.
- Health Risks: Excessive copper ingestion can lead to various health issues, emphasizing the need for filtration.
- Testing Methods: DIY test kits or professional services are available to determine copper levels in drinking water.
- Filtration Solutions: Activated carbon, reverse osmosis, distillers, and ion exchange systems effectively remove copper. Top brands offer reliable options, while DIY methods provide temporary solutions.
Copper is essential to health, but when absorbed in high doses through water it can be very unhealthy. Copper also gets into our water supply mostly through copper plumbing piping, especially in newer homes. It is beautiful in taste and color, although it’s not a mere cosmetic issue. When this happens too much, symptoms such as nausea, stomach cramps or even worse disease like kidney and liver damage develop. Filtration can be more clearly understood once you understand the copper effects on drinking water.
Although we need a little copper for health reasons, it’s important that the amount of copper we have in our water is within the recommended safe levels. Copper is indistinguishable from most other contaminants in water, meaning it can’t be seen or smelled, and therefore is a silent risk that needs to be actively tested and monitored.
How to Test for Copper in Your Drinking Water
Copper testing for copper is one of the first things you should do to ensure the health and safety of your family. It comes in different ways to do this. An alternative is DIY test kits, which are cheap, simple and can be found in almost all home improvement stores and online. They typically include instructions on how to draw and analyse water samples in these kits.
The second way is by hiring a professional water testing company, which is more accurate but expensive. : These usually involve professional technicians that take the water sample, test it and report back. This latter option is more accurate, but might not be for everyone, and DIY kits still give you a good indicator of copper levels in the majority of households.
The Legal Limits and Health Guidelines for Copper in Drinking Water
The Environmental Protection Agency (EPA) and the World Health Organization (WHO) have issued stringent regulations on how much copper you can have in your drinking water. Copper’s action limit is 1.3 mg/L (parts per million) according to the EPA. If water passes above this point, then you need to dilute the copper.
In contrast, WHO sticks to the same advice: keep a close watch on copper levels in drinking water. With this information, homeowners and communities can make educated choices about when to start filtering their drinking water for copper.
What are the different types of water filters that effectively remove copper?
Fortunately, many types of water filters can clean out copper from your water. One of the popular ones is activated carbon filters. They’re popular in pitcher filters and refrigerator filters and can remove copper in your water.
A reverse osmosis system is another useful copper depurator. This pump pushes water through a membrane that purges out contaminants, such as copper. Such systems are typically more expensive, but they can screen out most types of pollutants and are highly efficient.
Copper can be removed as well using distillers and ion exchange systems. Distillers evaporate water and hold the steam (as well as the copper and impurities). Ion exchange systems, on the other hand, exchange copper ions for less damaging ones, such as sodium, to get copper out.
Comparing Top Water Filter Brands for Copper Removal
There are so many filters in the market that can be overwhelming. Here are some of the best copper depilatory brands:
Berkey: The gravity-fed filters are popular for filtering 99.9% copper in water.
APEC: Their reverse osmosis systems are very effective for copper elimination and very long lasting.
Aquasana: Sells everything from whole house to countertop filter systems, which reduce copper levels.
ZeroWater: ZeroWater pitcher filters are cheap and come with 5-stage NSF-approved copper-reducing filter.
This list is not an exhaustive list and you will want to take into account other considerations like price, amount of water you need to filter every day, and contaminants in your water before you decide on something.
DIY Methods for Copper Removal
Although professional water filters are the most reliable copper removers, there are some DIY copper water reducers that you can try. These are not as efficient as professional filters, but they can be a one-way street:
Allowing Water to Run: If you have copper pipes, allow the water to run for a minute or so before draining it. This clears the water that has been collecting in the pipes and has probably absorbed copper.
Use Cold Water to Drink and Cook: cold water doesn’t retain copper as much as hot water, so always use cold water to drink and cook.
Acid Neutralizing Filters: You can make a very inexpensive acid neutralizing filter using crushed marble or limestone, which desolves copper.
And please don’t take these solutions for the place of an excellent water filtration system if your copper level is higher than the safe level.
Maintenance and Care for Copper-Removing Water Filters
Maintaining your water filter regularly is imperative if you want it to last and work efficiently. Any type of filter will have maintenance requirements that can be found in the product manual. These might include having to clean certain elements of the filter system on a regular basis, checking for leaks or corrosion, and replacing filters at an early stage.
Keep in mind that copper loss from a filter decreases over time as the filter gets saturated. Therefore, keep track of the age of your filter and replace it according to the instructions from the manufacturer.
Recycling and Disposal of Copper-Laden Filters
Decommissioning comes up at the end of a filter’s lifespan. Spent filters contain copper and may be filled with other contaminants, so don’t just dump them in the trash. Other brands have recycling services where you can recycle used filters and dispose of them.
If filters won’t fit back, ask your city recycling services. They have procedures or day-off for household toxic waste, such as clogged water filters. Reckless filter disposal doesn’t only help the environment, but is an aid in the mission of clean and safe water.
