What is a Water Filter, and How Does it Work?
Before we dive into the topic of expiration dates, it’s essential to understand the basics of water filtration. A water filter is a device designed to remove impurities and contaminants from water, making it safe for drinking. There are various types of water filters available, including activated carbon filters, reverse osmosis filters, and ultraviolet (UV) filters, each with its unique mechanism of action.
Activated carbon filters, for example, use a bed of activated carbon to absorb impurities and odors from the water. Reverse osmosis filters, on the other hand, use a semipermeable membrane to remove dissolved solids and other impurities from the water. UV filters use ultraviolet light to kill bacteria and other microorganisms that may be present in the water.
Why Do Water Filters Need to be Replaced?
Water filters need to be replaced regularly because they can become clogged with impurities and contaminants over time.
