What is the best way to filter drinking water?
Reverse osmosis filter systems are some of the strongest, most effective filters for drinking water. They are known to remove more than 99% of most dangerous contaminants in the water. That includes heavy metals, herbicides, pesticides, chlorine and other chemicals, and even hormones.
What size water filter removes viruses?
With a filter pore size of about 0.0001 micron, reverse osmosis is even better than nanofiltration at filtering out viruses. The CDC calls its performance very highly effective. Reverse osmosis is also very highly effective in removing other microbiologicals and common chemical contaminants.
Do carbon filters remove viruses?
Activated carbon filters will not remove microbial contaminants such as bacteria and viruses, calcium and magnesium (hard water minerals), fluoride, nitrate and many other compounds.
