Black Mold In Brita Pitcher

Maybe you may have noticed this green mold in Brita pitcher growing around the brim of our utensils. Many of us can’t elaborate on what they are.

These are the most headstrong bacteria that always manage to grow around us. As unwanted as these ubiquitous microbes are, it becomes even harder to eliminate them from our homes forever.

You can call them the top species, given how simply these bacteria can survive and breed in any environment.

It is easy for them to grow in suitable areas, which makes it difficult to destroy them forever.

If these bacteria are not removed quickly, they can seriously harm the longevity of the host property.

In addition to being slimy, disgusting mites, mold, and mildew can also threaten the host’s structural well-being.

Brita filter claims to purify your water, and Brita can’t remove Coliform Bacteria, Fungus, Viruses, Fluoride, and Arsenic.

The activated carbon property of the charcoal in Brita products will do nothing to cause any mold to grow around it. Even if there are some traces of organic material

Molding spores can’t grow on activated carbon. What you are looking at is black mold on the Brita filter pitcher. It is a form of mold that only grows in a bio-film or a relatively narrow habitat.

Which is equivalent to a 2-inch weed-covered patch of ground. The mold grows in the narrow habitat, not in the larger environment or surrounding space.

It was first known as a mold because it looks like mold, which appears black on a white object.

Difference between mildew or mold

The main difference between mold and mildew

Molds are categorized as fungi that have multiple identical nuclei.

These bacteria can see in greenish and blackish colors. However, mildew is nothing but a particular subspecies of molds.

Now, mainly molds are a dangerous threat because they are identified to plunge into the surfaces of things and decide to grow deeper into them.

The risk of mildew is slightly lower as they only survive and breed in flat areas and can be easily eradicated.

You can easily find mold on old walls, cracks, surprisingly on food, and sometimes in Brita water filter pitchers.

However, it grows in wet areas such as organic materials, paper, plastic, etc.

Pink mold in Brita pitcher

Pink mold in Brita pitcher

Few Brita customers face pink stains or residues that hardly develop in their Brita water filter pitchers.

It can grow around the sink, tub drains, toilet bowls, shower curtains, and even in pet water bowls.

Users naturally want to understand if something is wrong with their drinking water.

No, a pink deposit is not a problem with your hard water and is not dangerous in this condition.

These are common bacteria in our environment, and the type of these bacteria is recognized as Serratia marcescens.

These bacteria grow in natural sources such as dust, soil, mulch, and surface water, where high phosphate moisture helps to develop.

For example, a pink mold in Brita pitcher frequently develops when dirt and dust containing Serratia enter the pitcher.

Chlorinated drinking water is not suitable to survive Serratia.

It mostly happens in untreated tap water, private groundwater supply, and in the summer when temperatures and humidity are higher.

Using an activated carbon filter, those who eliminate the chlorine smell and other contaminants from their drinking water may have more chances of experiencing pink mold.

Why Do I Need A Brita Water Filter?

Hard water treatment systems work by passing water through an activated carbon block that removes harmful chemicals. 

Activated charcoal works well at removing chlorine, which makes drinking water safe. 
However, some people have trouble getting their water to taste good without adding extra flavoring agents. 

These additives add color and flavor, and chemical compounds that are bad for you.

Drinking water treated with a Brita water filter tastes great because the water is free of these artificial flavors, colors, and preservatives.
