· Limestone is a sedimentary rock. It’s made up of calcium carbonate. It forms from the shells and bone fragments of organisms, meaning it has lots of fossils. It’s a great building material and is used for flooring, walls, and decoration. Limestone often has fossils that give us a glimpse into the past.

Micron ratings are used to measure the size of particles that a water filter can effectively remove. A micron is equal to one-millionth of a meter, or about 0.00004 inches. To put this into perspective, human hair is typically around 50-100 microns in diameter. Water filters are designed to capture particles that are larger than their micron

· It measures the maximum size of contaminants that will pass through the filter and be left in your drinking water. A lower micron rating means smaller particles will be filtered out, while a higher rating indicates larger particles will make it into your water. Common micron ratings range from 0.5 to 50 microns.

· The micron rating of the filters in your water filtration system will determine how effective it is. The contaminants that are removed will depend on the size of the filter, which can range from 0.0001 to 800 microns. The higher the micron rating, the bigger the particles it can trap.
