Q. The eSpring Water Purifier removes particulates as small as 0.2 microns. Some competitive systems claim they remove particles as small as 0.1 micron. Is this a significant difference?
A. A difference of one–tenth of a micron does not provide significantly greater filtration effectiveness. Micron size is only an effective measure of the product’s ability to trap particulates such as sediments and cysts. Since the smallest cysts are larger than 0.2 microns, a 0.1 micron screen will not improve efficiency. Some manufacturers claim a 0.1 micron filter will remove bacteria, since many bacteria are larger in size than 0.1 micron. Although the filter may stop the bacteria for a short period of time, its removal performance may be lower over a period of months. Even though bacteria may be larger than the 0.1 micron pores, the bacteria can eventually pass through. However, a 0.1 micron filter may be more susceptible to premature plugging, and therefore require more frequent replacement. In addition, particle removal methods are not effective for viruses, which may be a fraction of the size of the smallest bacteria.
