Three well-known filters—Brita, Pur, Zerowater—and an unknown filter were tested with water containing TDS and lead.
Zerowater filtered out the most TDS.
Water supplies are disinfected with chlorine to reduce disease-causing bacteria and microorganisms. It improves water taste and may reduce odors.
However, chlorine can harm your health, especially if you’re sensitive. Excess chlorine can dry, itchy, and flake skin and hair, causing dandruff and itching.
Get a water filter if you’re worried about chlorine in your tap water. Reverse osmosis and activated carbon filters are popular.
According to the EPA, municipal water treatment facilities should keep residual chlorine levels below four mg/L. However, check with your water company due to slight chlorine variations in tap water.
Lead is a dangerous heavy metal that can cause kidney and heart failure in adults, reproductive disorders in children, and cancer. Due to this information, many people try to limit their exposure.
Before trying any lead removal methods, the CDC recommends testing the water. This can be done with a free test kit from your local water authority.
Consider installing a whole-home lead filtration solution to filter all water in your home if the results show high lead levels. These systems are expensive but worth it for peace of mind.
The Longlast+ and faucet filter are Brita’s lead-removing models. NSF/ANSI 53, the industry standard for a lead reduction in drinking water, is met by both filters.
Filters remove contaminants from drinking water to improve taste, odor, and safety. Certain chemicals may even be reduced.
Many people use water filters to remove contaminants like hardness, arsenic, and low fluoride for health reasons.
Active filter agents and mesh media in Brita’s Elite and Longlast+ filters filter chlorine (taste and odor), copper, cadmium, and mercury, which can be harmful if inhaled.
Both filters cannot completely remove lead from drinking water.
Filters should be changed every 40 gallons to prevent lead in drinking water.
However, if you don’t replace your filters, lead in your tap water can build up and cause health problems. The CDC recommends testing your water for lead to see if it’s safe for your family.
Some water contaminants are harmful at high concentrations. Lead is toxic when ingested.
Brita filters reduce various pollutants, depending on the model. Some remove copper and zinc from water with ion exchange resin.
They have a carbon block that removes taste and odor from water but cannot kill bacteria.
Adsorption traps contaminants in activated carbon, a popular water treatment method. Chlorine, chlorine compounds, and some pharmaceuticals are removed by activated carbon.
The Longlast+ and standard Brita filters reduce contaminants better than others. For instance, the Standard filter reduces 99% of lead, while the Longlast+ eliminates over 80 contaminants.
