Preventing Cryptosporidiosis
According to the CDC, some, but not all available water filters remove Cryptosporidium. Some of these filter designs are more suited to removing Cryptosporidium than others. Both RO (Reverse Osmosis) filters and filters that work by micro-straining will work. Look for a filter that has a pore size smaller than 1 Micron. This means that the filter will remove microbes that are 1 micron or larger. There are two types of pore size: “Absolute Micron” and “Nominal Micron” — Absolute will consistently remove microbes larger than the stated pore size. Nominal will allow 20% to 30% of the microbes at that size pass through. Make sure you talk to the manufacturer of the product to be sure the filter is filtering as you require it.
The Pure Water 2GO Biological Bottle has an Absolute .2 Micron Filter. With this pore size being much smaller than 1 Micron, the Biological Bottle not only filters out Crypto, but many other organisms that may be much smaller than 1 micron.
