Sustainably Grown Coconut Carbon

Coconut Carbon

Coconut carbon continues to grow in popularity in a variety of filters because of its ability to absorb and capture particles passing through it.

Up to 85-90% of coconut shells are covered in micropores which happen to be the same size as many of the contaminants we don't want in our air and water. This small micropore size makes it ideal for absorbing and capturing these particles.

Sustainably Grown

Many of the raw materials used for carbon are non-renewable resources such as bamboo, willow peat, wood, coir, lignite and coal. 

However, coconuts are a renewable source of carbon compared to these alternatives. Coconuts are grown year-round and harvested up to 4 times each year on trees that can be preserved for many years. 

How We Use It 

Filter-Monster uses coconut carbon in refrigerator water filters and air purifier pre-filters. 

Water Filters

The use of natural, coconut carbon in our water filters helps to absorb and capture contaminants from water passing through. Coconut carbon helps achieve cleaner, healthier drinking water in your home. 


Coconut carbon pre-filters helps reduce common household odors from cooking, cleaning and pets. The pre-filter also captures larger particles before reaching the HEPA filter, extending the life of the HEPA filter.

Healthier Water with NSF/ANSI 42, 53 and 401 Certifications

Counterfeit Filters

According to Filter It Out, counterfeit water filters have flooded the market in recent years. These filters go beyond illegal use of brand names and logos, but also make false claims about filter performance and what is actually filtered out of water.

Counterfeit water filters can do the following:

  • Fail to filter harmful contaminants from your water
  • Add harmful contaminants to your water
  • Leak and damage refrigerator


NSF Certifications

The National Sanitation Foundation regulates refrigerator water filters and rigorously tests every part of a filter before it can earn a NSF Certification, making it a widely known and respected sanitation regulatory body.

But even within these strict regulations, some certifications are better than others. For example, a filter with a NSF 42 Certification only removes the taste and smell of chlorine in your water while other contaminants may still get through. 

That's why it's important to make sure your refrigerator water filter is held to the highest standards. All Filter-Monster water filters are certified by IAPMO Research and Testing to NSF/ANSI 42, 53 and 401 for the specific performance claims verified and substantiated by test data. See entire list of contaminants below.

True HEPA Filtration

Common Misconceptions

Clever marketing has flooded the market with filters that are not effective at filtering the air you breathe. Claims like HEPA-Type, HEGA and more are creative ways to hide that a filter doesn't meet industry standards. 

True HEPA 

A High Efficiency Particulate Air (HEPA) filter must satisfy certain standards of efficiency, according to the United States Department of Energy. 

In order for a True HEPA filter to meet this standard, it must remove 99.97% of particles from the air as small as 0.3 microns in size. 

Hard to visualize how small a micron is? Check out our chart below:

A filter's efficiency refers to how many particles are trapped and removed from the airflow passing through the filter. At 99.97% efficiency, only 3 particles escape from every 10,000 passing through the filter. True HEPA filtration captures smoke, dust, pollen, pet hair and dander, mold spores and dust mites. 


While HEPA-Type filters appear to be similar to True HEPA filters, they are not standardized and cannot match the performance.

HEPA-Type filters don't typically disclose the size of particles filtered. They may claim to filter 99.9% of particles, but they don't say how small those particles are. They may only filter out larger particles, but allow smoke and mold spores to get through and enter your home again.
