John woodard our master water specialist explains the difference between a 1 micron 5 micron 5 micron or 10 micron filter.
													
																	Water filter 5 micron vs 1 micron. 
									
		
	
	
		
	
	
		
	
	
		
	
																	0 4 micron bacteria will pass through a 1 micron filter size so to ensure you are removing all the bacteria possible you should opt for 0 4 microns or smaller in terms of filter size. 
																	The amount that will get removed during water filtration depends on whether a nominal or absolute filter is used. 
																	For most purposes nominal filters are fine but when very high grade water is required an absolute rated filter may be needed. 
																	A nominal 5 micron filter is one that traps 85 percent of the particles of five microns and larger. 
															
													
									
		
	
	
		
	
	
		
	
	
		
	
																	One micron filters will remove parasites from the water as well as a lot of but not all bacteria. 
																	A nominal micron rating is the. 
																	Whole house models have the 5 micron because a 1 micron whole house filter would clog up and have to be replaced too frequently. 
																	Carbon block is 0 5 microns. 
															
													
									
		
	
	
		
	
	
		
	
	
		
	
																	Common micron ratings for filters are 100 75 50 25 10 5 1 and 0 5. 
																	An absolute 5 micron filter is one that traps 99 9 percent of the particles of 5 microns and larger. 
																	Sediment filters remove different contaminants depending on their micron rating. 
																	The difference between nominal and absolute micron rating. 
															
													
									
		
	
	
		
	
	
		
	
	
		
	
																	A micron is a unit of measurement describing the pore size of a micron water filter. 
																	Some whole house customers choose a 1 micron prefilter. 
																	Bacteria usually range from between 0 4 and 2 microns in size. 
																	For city water and other chlorinated water supplies.
