Do Brita Filters Remove Lead

What is lead?


Lead is a highly toxic metal that can be found in various sources, including water. It is a heavy metal that has been used in many different industries, such as construction, manufacturing, and plumbing. Due to its widespread use in the past, lead has become a significant concern for public health.

Sources of lead

Lead can enter the environment through various sources, including old paint in buildings, soil contaminated with leaded gasoline emissions, and household plumbing materials.

In the context of water, lead can leach into drinking water when it comes into contact with lead pipes, lead solder, or brass fixtures that contain lead.

Health effects of lead

Exposure to lead can have severe health consequences, especially for infants, children, and pregnant women. Even at low levels of exposure, lead can cause developmental delays, decreased IQ, behavior and learning problems, and damage to the nervous system.

In adults, lead exposure has been associated with kidney damage, cardiovascular effects, and reproductive issues.

The importance of removing lead

Lead exposure risks

Given the harmful effects of lead, it is crucial to minimize exposure to this toxic metal. Drinking water is one of the potential sources of lead exposure, particularly if homes or buildings have old plumbing systems.

Lead can dissolve into tap water, making it necessary to take adequate measures to remove it and ensure safe drinking water.

Health concerns

Exposure to lead, even at low levels, can have serious health implications. Children and pregnant women are especially vulnerable to the harmful effects of lead.

Children who are exposed to lead may experience learning difficulties, decreased intelligence, and behavioral problems. Pregnant women can pass lead to their unborn babies, potentially causing developmental issues.

Legal limits

To address the health risks associated with lead in drinking water, regulatory agencies have established legal limits for lead concentration in tap water. In the United States, for example, the Environmental Protection Agency (EPA) has set the Maximum Contaminant Level Goal (MCLG) for lead at zero.

However, this goal is not enforceable, and the allowable action level is 15 parts per billion (ppb) for public water systems.

How Brita filters work

Filtration methods

Brita filters use a combination of ion exchange, activated carbon, and mechanical filtration to remove impurities from drinking water. The activated carbon in the filter helps to reduce contaminants, including chlorine taste and odor, while the ion exchange resin targets heavy metals like lead.

Contaminant removal

Brita filters are designed to remove a variety of impurities, including certain heavy metals like lead. While the specific effectiveness against lead can vary depending on the model and age of the filter, Brita filters can generally reduce lead levels in drinking water to some extent.

Certifications and testing

NSF International certification

Brita filters undergo rigorous testing and certification by organizations such as NSF International. NSF International is an independent, third-party organization that sets standards for product safety and performance.

Brita filters that carry the NSF certification have been tested and proven to effectively reduce or remove specific contaminants, including lead.

Lead removal testing

To assess the effectiveness of Brita filters against lead, independent testing has been conducted. These tests measure the reduction in lead levels achieved by the filters.

While Brita filters can help reduce lead concentrations in drinking water, it is important to note that their effectiveness can decrease over time and vary depending on factors such as water pH, flow rate, and initial lead concentration.

Effectiveness of Brita filters against lead

Filter lifespan considerations

The effectiveness of Brita filters in removing lead can depend on the lifespan of the filter. Over time, the filter’s ability to reduce contaminants, including lead, may diminish. It is recommended to replace the filters regularly as per the manufacturer’s instructions to ensure optimal performance in lead removal.

Filter pore size

The pore size of a filter can also impact its effectiveness against lead. Brita filters typically have a pore size of around 0.5 microns, which can effectively remove larger particles and some microorganisms.

However, lead particles can be smaller than 0.5 microns, so it is important to consider this limitation when relying solely on Brita filters for lead removal.

Effectiveness against different types of lead compounds

It is worth noting that the effectiveness of Brita filters against lead may also vary depending on the form in which the lead is present in the water.

Brita filters may be more effective at reducing lead ions compared to other forms of lead compounds. It is advisable to consult the manufacturer’s specifications or conduct independent testing to determine the filter’s efficacy against specific lead compounds.

Limitations of Brita filters

Inability to remove all lead

While Brita filters can reduce lead levels in drinking water, it is essential to acknowledge that they may not completely remove all traces of lead. Factors such as the initial lead concentration, contact time with the filter, and the age and condition of the filter can influence its ability to effectively remove lead.

Therefore, it is prudent to consider additional measures to minimize lead exposure, especially in areas with known or suspected lead issues.

Other potential sources of lead contamination

Brita filters primarily address the lead content already present in tap water. However, it is important to recognize that other sources of lead contamination in the household, such as old pipes and plumbing fixtures, can contribute to lead exposure.

For comprehensive lead reduction, it may be necessary to address these potential sources in addition to using water filters.

Usage tips for maximizing lead removal

Flushing the filter

To enhance the effectiveness of Brita filters in removing lead, it is recommended to flush the filter prior to use. Flushing helps remove any trapped air or loose carbon fines, improving the flow of water and allowing the filter to efficiently reduce lead levels.

Replacing filters regularly

Regular filter replacement is crucial for maintaining optimal performance in lead removal. Brita advises replacing the filter cartridge approximately every two months or after filtering approximately 40 gallons of water.

Following the manufacturer’s instructions regarding filter replacement is essential to ensure the continued removal of lead and other contaminants.

Filter maintenance

Proper maintenance of Brita filters can contribute to their effectiveness in lead removal. It is recommended to clean the filter housing regularly, as well as regularly washing the pitcher or dispenser with mild soap and warm water.

Failure to maintain the filter and associated equipment may compromise the performance of the system.

Other water treatment options for lead removal

Reverse osmosis systems

Reverse osmosis systems are highly effective at removing lead from drinking water. These systems use a semi-permeable membrane to effectively filter out impurities, including lead.

However, they often require professional installation and can be more expensive than other options.

Activated carbon filters

Similar to Brita filters, activated carbon filters can help reduce lead levels in drinking water. These filters work by adsorbing contaminants onto the carbon surface. However, their effectiveness in lead removal may vary depending on the specific model and the level of lead contamination.


Distillation is another water treatment method that can effectively remove lead. The process involves boiling water, capturing the resulting steam, and then condensing the steam back into liquid form.

This process effectively removes impurities, including lead. However, distillation systems can be costly and may require regular maintenance.

While Brita filters are a popular choice for improving the taste and quality of drinking water, their effectiveness in removing lead should be considered as part of a comprehensive lead reduction strategy.

While they can help reduce lead levels, it is important to be aware of the limitations of Brita filters and the potential presence of other sources of lead contamination.

Regular filter replacement, filter maintenance, and awareness of additional water treatment options can contribute to maximizing lead removal and ensuring the availability of safe drinking water.
