Brita water filters are popular for improving the taste and quality of drinking water, but they do not effectively remove Legionella bacteria. These filters are designed to reduce contaminants like chlorine, lead, and particulates, but they are not certified for removing bacteria or viruses, including Legionella.
What Does a Brita Water Filter Remove?
Brita water filters are primarily designed to enhance water taste and reduce specific contaminants. Here’s what they typically filter:
- Chlorine: Reduces the taste and odor of chlorine in tap water.
- Lead: Removes lead, which can be harmful even in small amounts.
- Mercury: Reduces mercury levels, which can be toxic.
- Benzene: Filters out benzene, a harmful chemical found in some water supplies.
- Copper: Reduces copper, which can cause gastrointestinal distress.
- Zinc: Reduces excess zinc, known for causing an unpleasant taste.
Why Doesn’t Brita Filter Out Legionella?
Legionella is a type of bacteria that can cause Legionnaires’ disease, a severe form of pneumonia. Brita filters are not designed to remove bacteria or viruses because they use activated carbon and ion-exchange resin, which are effective for certain chemicals and metals but not for microbial contaminants.
How to Ensure Safe Drinking Water?
To protect against Legionella and other bacteria, consider these alternatives:
- Boiling Water: Boil water for at least one minute to kill bacteria.
- UV Purifiers: Use ultraviolet light purifiers designed to kill bacteria and viruses.
- Reverse Osmosis Systems: These systems can remove bacteria, viruses, and other contaminants.
- Certified Microbiological Filters: Look for filters certified by NSF/ANSI Standard 55 or 58 for microbial reduction.
Understanding Legionella and Its Risks
Legionella bacteria thrive in warm water environments, such as hot tubs, cooling towers, and plumbing systems. They can be inhaled through water droplets, leading to Legionnaires’ disease. It’s crucial to maintain and clean water systems regularly to prevent bacterial growth.
How to Prevent Legionella in Home Water Systems?
- Regular Maintenance: Clean and disinfect water systems, including water heaters and plumbing.
- Temperature Control: Maintain water heaters at 140°F (60°C) to inhibit bacterial growth.
- Flushing Systems: Regularly flush hot and cold water systems to prevent stagnation.
People Also Ask
Can Brita Filters Remove Bacteria?
No, Brita filters are not designed to remove bacteria or viruses. They focus on reducing certain chemicals and metals for improved taste and safety.
What Filters Remove Legionella?
Filters certified under NSF/ANSI Standard 55 (UV treatment) or 58 (reverse osmosis) can effectively reduce Legionella in water.
Is Legionella Common in Tap Water?
Legionella can be present in tap water, especially if water systems are not properly maintained. It thrives in warm, stagnant water environments.
How Often Should Water Filters Be Replaced?
Brita recommends replacing filters every 40 gallons or approximately every two months, but always follow the manufacturer’s guidelines for specific products.
What Are the Symptoms of Legionnaires’ Disease?
Symptoms include cough, fever, muscle aches, and headaches. It’s essential to seek medical attention if these symptoms appear after exposure to water aerosols.
Conclusion
While Brita water filters improve the taste and quality of tap water by reducing certain contaminants, they are not designed to remove Legionella bacteria. For comprehensive protection against bacteria and viruses, consider using methods like boiling, UV purification, or reverse osmosis systems. Regular maintenance and proper temperature control in home water systems can also help prevent Legionella growth.
