Manifold Inlet

Usually part of a point of use water filtration system, a manifold inlet is a part that allows water to flow from the Water Storage Tank into the System Manifold.

Membrane Filter

Typically used with Reverse Osmosis systems, this semi-permeable filter features holes so tiny that only something the size of a water molecule or smaller can pass through. Reverse Osmosis membrane filters typically remove dissolved solids smaller than one micron (500x smaller than the period at the end of this sentence).


Also known as a microorganism, microbe refers to a pathogenic bacterium. Well-owners should make themselves very familiar with microbes, as untreated well water tends to be rife with them.

Also called a micrometer, the micron is used to measure wavelengths, as well as cells and bacteria. A single micron is about 500 x smaller than the period at the end of this sentence. Talk about tiny!


Microorganisms or microscopic organisms are too small to be seen by the human eye. They can be single or multi-cellular and include things like bacteria, fungi, algae, mites and even some crustaceans.


Minerals are naturally occurring chemical compounds, usually crystalline in form. There are certain minerals that the human body absolutely needs in the diet. These trace minerals are commonly consumed with our food and drinking water, but over-cleansing or over-purifying can make that tricky. See remineralizer.


A molecule is the smallest physical unit of an element or compound. Yes, atoms are smaller, but they aren’t specific to a certain compound. Side-note: RO systems have membranes whose holes are so tiny only water molecules can fit through them. That’s why RO is the only way to remove fluoride.

Mountain Top Mining

Miners use explosives to reach coal seams from the top down when using mountain top mining. This type of mining is used in the Appalachian Mountains in the eastern US.


During a mudslide, mud rushes down a slope enveloping most everything in its wake. They are most often caused by heavy rainfall after a drought, earthquake or volcanic eruption.
