 Class II particulates = filtered particle size: Class II - 1 to 5 microns January 20, 2007
31 out of 35 found this review helpful
The term, "Particulates" refers to particles of rust, dirt, sand, and sediment found in drinking water. Water that contains Particulates is typically cloudy, and as you might expect, tastes and smells "dirty". By themselves, Particulates are not known to cause any adverse health effects, but they can sometimes carry other harmful organic, inorganic, and microbiological contaminants through the drinking water system.
In general, better filters will remove finer particles. Each filter's ability to remove particulates is measured against a certain "particulate class", or particle size.
Class I - 0.5 to 1 micron
Class II - 1 to 5 microns
Class III - 5 to 15 microns
Where one micron is one millionth of a meter or approximately 1/25,000 of an inch.
For example, if a filter is rated to remove "95.1% of Particulates (Class II)", that just means that it will remove 95.1% of all particles that are between 1 and 5 microns in size

This product represents great value for money and is etremely easy to install.
The manufacturer recommends changing every 6 months, but I'm sure it's 'water quality' dependent as my filters last at least 12 months (Fort Collins, CO has great water quality).

The filter I bought from Amazon for my Whirlpool refrigerator is exactly the same as the one I purchase for more money at my appliance store.
