ACTIVATED CARBON FILTRATION

MICRON RATINGS

Micron ratings on a water filter indicate the smallest particle size that the filter is designed to effectively capture and remove from the water. The micron rating is measured in micrometers (µm), where one micrometer is equivalent to one millionth of a meter.
 

Human hair typically has a diameter ranging from about 30 to 180 micrometers (µm), which means it falls within the range of 20 µm to 180 µm. Therefore, human hair is larger than 5 micrometers and would effectively be captured by a filter with a 5-micron rating, even if we split the diameter 5 ways!

For example, if a water filter has a micron rating of 5 µm, it means that the filter is capable of capturing particles that are 5 micrometers in size or larger. Particles smaller than the specified micron rating might still pass through the filter.
 

Different water filters are designed with varying micron ratings to target different types of contaminants. It's important to note that the micron rating alone doesn't provide a complete picture of a filter's performance. Factors such as the filter material, design, flow rate, and overall filtration technology also play a significant role in how effectively a filter can remove contaminants.
 

Carbon filters often have lower micron ratings (e.g., 0.5 µm, 1 µm, or 5 µm) than sediment filters and are effective at removing finer particles and some microorganisms, as well as improving taste and odor by adsorbing organic compounds. For food service treatment of municipal water (which has already been made potable), a 5 µm rating provides exceptional capacity for removal of contaminants while reducing the potential to prematurely load with dirt and clog, stopping water flow to critical equipment. For any commercial food service operations that operate with well water, WaterWise recommends a sub-micron filter (e.g., 0.2 µm, 0.015 µm) to remove microorganisms and potential pathogens, bacteria, or viruses from the water. It is also advisable to treat such water with aqueous ozone generators (AOG) post filtration for an additional measure of safety.
 

It's important to note that the micron rating alone doesn't provide a complete picture of a filter's performance. Factors such as the filter material, design, flow rate, and overall filtration technology also play a significant role in how effectively a filter can remove contaminants.

When selecting a water filter, it's essential to consider the specific contaminants you want to target and choose a filter with an appropriate micron rating and filtration capability. Keep in mind that using filters with different micron ratings in a multi-stage filtration system can help address a wider range of contaminants and improve overall water quality.
 

It's important to note that while carbon block filters are effective at removing a wide range of contaminants, they might not be suitable for removing all types of impurities, such as certain minerals, heavy metals, or microorganisms. Depending on your water source and the specific contaminants you're concerned about, you might need additional filtration methods in combination with a carbon block filter to achieve comprehensive water purification.
