What Do PUR Water Filters Filter Out? A Look at Water Filtration Efficiency
What Do PUR Water Filters Filter Out?
Clean water is essential for both domestic and industrial use. While household brands like PUR offer decent filtration for personal use, they fall short when it comes to high-efficiency water purification required in commercial and industrial environments. So, what exactly do PUR water filters filter out—and how do they compare to industrial-grade systems like reverse osmosis (RO) membranes?
What PUR Water Filters Remove
PUR water filters are designed primarily for home use. They typically filter out:
-
Chlorine and taste/odor: Improves the taste of tap water.
-
Lead: A common heavy metal in old piping systems.
-
Mercury: Harmful even in small amounts.
-
Pharmaceuticals and pesticides: Limited removal based on filter model.
-
Sediments and particulates: Such as dirt and rust.
-
Microbial cysts: Like Cryptosporidium and Giardia.
While PUR filters can improve water quality for home consumption, they have limitations in flow rate, capacity, and contaminant range.
Industrial Needs Go Beyond Basic Filtration
For industrial and commercial applications, advanced filtration is necessary. This includes removing:
-
Dissolved solids (TDS)
-
Heavy metals (arsenic, cadmium, chromium, etc.)
-
Chemical pollutants
-
Biological contaminants
-
Salinity (in seawater or brackish sources)
This is where reverse osmosis membranes outperform typical household filters.
