1 Micron - 10 Micron - 20 Micron - Water Filters 

What's the Difference?

For household water filter needs: 

 

Beach Sand needs 40 micron to 500 micron filters (if you can see sand only)
Fine grit needs 20 to 40 micron filters (if you see or feel grit and sand)
Silt 5 to 20 micron filters  (discolored and muddy)
Cryptosporidium & Giardia Cysts need 1 micron filters (not visible to the naked eye)

Paper, String and Poly Spun for Rust and Sediment -  from 5 to 40 microns.
Carbon block is 0.5 microns 

 

For city water and other chlorinated water supplies. 
RS1 20 Micron   or   TO1 10 Micron 
RS7 40 Micron   or   RS2 5 Micron 

For well water systems
RS3 20 Micron   or   RS2 5 Micron 
TO3 10 Micron    or   RS7 40 Micron

Carbon Wrapped for taste and odors.
TO1 10 Micron - City Water   /   TO3 10 Micron - Well Water 

Carbon Block for taste and odors plus reducing bacteria. Cryptosporidium and Giardia cysts: 
CB1 0.5 Micron   or  CB3 0.5 Micron - plus metals and VOCs

 

What are the Filter Classes?

Particulate/Sediment
Note: Particulate reduction is divided into six classes:

Class I - 0.5 to < 1 micron in size
Class II - 1 to <5 microns in size
Class III - 5 to <15 microns in size
Class IV - 15 to <30 microns in size
Class V - 30 to <50 microns in size
Class VI - >50 microns in size

Water filters with a Standard 42 (aesthetic effects) certification are designed to minimize non-health related contaminants such as chlorine, taste and odor, and particulates. These filters sorted by classes of performance. For all other claims, there is only a pass or fail.
For taste & odor, the classes represent chlorine reduction efficiency:
Class I, a minimum of 75% chlorine reduction.
Class II, 50% reduction.
Class III, 25%.

For mechanical filtration, the classes represent particle size ranges that are removed with a minimum 85% efficiency:
Class I, � -1 micron.
Class II, 1-5 microns.
Class III, 5-15 microns.
Class IV, 15-30 microns.
Class V, 30-50 microns.
Class VI, 50+ microns.

It�s important to note a Class I or Class II rating does not imply cyst reduction. In order for a water filter to qualify for cyst reduction, it must have a 99.95 percent minimum filtration efficiency for 3-4 micron test dust particles, 3.000 micron micro-spheres, or live cryptosporidium oocysts.

 

Carbon Wrapped for taste and odors plus reducing bacteria.

Carbon Block for taste and odors plus reducing bacteria will be 0.5 microns to 1 microns.

Because of the product�s limited service life and to prevent costly repairs or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced every ten years. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately. Date the bottom of any new or replacement housing to indicate the next recommended replacement date.
