How Effective Are Brita Filters

Is great taste essential for you when drinking water? Probably, it’s a yes since it drives you to drink more. 

However, it is also critical to ensure that you are drinking clean water. Remember that contaminants are often present in drinking water. According to the World Health Organization (WHO), contaminated water transmits diseases such as polio, typhoid, dysentery, cholera, and diarrhea.

That is why more and more people are getting interested in water filtration systems like Brita Filters. If it is your first time hearing about these water filters, keep reading and discover how effective they are.

Let’s get started!

What is a Water Filter?

water filter provides a way to remove impurities and contaminants using a fine physical barrier. It ensures that you have access to safe drinking water. Brita filters may not deliver health benefits, but they help minimize the risks of potential health issues. 

Once you drink contaminated water, you may experience immediate health effects like dizziness and nausea. According to the Environmental Protection Agency (EPA), some contaminants deliver long-term effects, such as liver and kidney damage, nervous system disorders, and increased cancer risk. 

How Effective Are Brita Filters and Are Brita Filters Safe?

Brita filters remove contaminants and impurities from drinking water. They are certified by the National Sanitation Foundation (NSF). In other words, they meet the safe drinking water requirements.

Besides the NSF certification, the Water Quality Association (WQA) also certified these filter systems under the Gold Product Certification Program.

As you probably know, any product with WQA Gold Seal meets or exceeds the industry standards for particular contaminant reduction, material safety, and structural integrity.

How Do Brita Filters Work?

According to Brita, water filters work like a sieve. They use carbon to reduce the mercury content and smell and taste of chlorine. An ion-exchange resin is also present to filter other elements, such as cadmium, copper, and zinc. 

These water filters come with pores that control the components that should get through them. Since these pores have varying sizes, the filtration results vary. 

During the filtration process, pores trap larger particles while the positively charged materials attract negatively charged ions in smaller contaminants. As a result, the water contaminants stick to the water filter.
