Triple Big Blue Filter Set: 1 Micron, Activated Carbon Block, & 0.1 Micron
Additional Options
Change Standard 1 Micron Melted Spray to Antibacterial Option
The Melted Spray Antibacterial filters like the standard melted Spray type are designed to capture dirt, sediments, visible particles, and bacteria.
However, the Melted Spray sediment filters have had a silver ion additive added to their material, which creates a bacteriostatic function to inhibit the growth of bacteria on the surface of the filter, helping to ensure healthier product water and a longer life span of the filter.
This option is ideal for source waters that have a very high bacterial / organism count and will help to extend the life of the filter.
What does the iodine number for activated carbon mean?
Many carbons preferentially adsorb small molecules. Iodine number is the most fundamental parameter used to characterize activated carbon performance. It is a measure of activity level (higher number indicates a higher degree of activation) often reported in mg/g (typical range 300–1200 mg/g). It is a measure of the micropore content of the activated carbon (0 to 20 Å, or up to 2 nm) by adsorption of iodine from the solution. It is equivalent to the surface area of carbon between 900 and 1100 m2/g. So essentially the greater the Iodine Number Rating on an Activated Carbon Block, the more effectively the carbon will absorb things such as chlorine and organic molecules.
Change Nominal 0.1 Micron to Absolute 0.1 Micron Pleated Filter Option
If you select a filter set with the 0.1 Micron Pleated Filter then you will have the option of either a "Nominal" or "Absolute" Pleated Filter for the 0.1 Micron.
Most sediment filter cartridges such as the standard 0.1 Micron Pleated Filter, have what is referred to as a nominal filter rating. Essentially what this means is that the micron rating of a filter is the approximate "average" size (diameter) of the pores on its surface and within the cartridge itself. It is generally accepted that filters with nominal filter ratings will retain (trap) around 85% of the particles equal or greater in size to the stated micron rating.
An "Absolute" filtration rating means that the filter material has been specifically manufactured, and passed lab testing to ensure that 99.9% of the particles larger than the stated micron rating will be captured (trapped) on the surface or within the filter itself. In the case of our 0.1-micron Absolute Filters, this means that you will get the most effective removal of bacteria and organisms possible with 20" Big type Filter Cartridges.
