Do You Know What Harmful Substances Can be Removed by a Water Filter?

How to choose a water filter?
 What kind of water purifier is more suitable for me? Can the water from the water purifier be directly drunk? Is the water from the water purifier harmful to the human body?
Filter method
The filtration method of water filter is generally through physical retention, physical adsorption and other methods.
The water treatment method of the water purifier is purely physical and does not filter by chemical means.
The RO membrane reverse osmosis filtration accuracy commonly used in water purifiers is equivalent to one-800,000th of hair
The size of impurities in the water
The size of impurities in the water has been scientifically tested as follows:
·Bacteria 0.4~5 microns
·Virus 0.01-0.1 micron
·Antibiotic 0.001-0.01 micron
·Heavy metal 0.0005-0.005 microns
 Inorganic material 0.0002 to 0.0005 micron
·The molecular weight of organic matter is greater than 100
How effective is the filtering
How about the filtration accuracy of the water filter?
Bacteria removal rate: 99.9%
Organic matter removal rate: 99.7%
Heavy metal removal rate: 99.9%
Antibiotic removal rate: 99.9%
What are you worried about with such a removal rate?
