As you can see, Legacy can provide large families all the pure drinking and cooking water they need for less money.  Or for those of us who like to give our pets and plants clean water too, choosing Legacy means we can afford to be generous!   Legacy is simply the best water filtration system you can find!  Use in your kitchen under the sink; use with your bottle-less water cooler, or use for ingredient water for hobbies such as beer and wine making. 

Filter Certification is for each contaminant under the applicable Standard.  Certification for one contaminant does not mean the others listed are also certified.
• Standard 42 for Chlorine, Taste, Odors, Sediments at 2.5  gallons per minute.  Chemical reduction for taste improvement:  Chlorine, chloramine, ammonia, hydrogen sulfite, metallic tastes.

Class I Particulate reduction: to >.5 microns;
Class II: 1 to <5 microns;
Class III: 5 to <15 microns;
Class IV: 15 to <30 microns;
Class V: 30 to <50 microns;
Class VI: >50 microns.  (One Micron = 39 millionths of an inch. A grain of salt is about 60 microns.)

• Tested by Selecto Scientific Laboratory for Standard 53 (health effects) for the reduction of specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs)**, MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.

• Certifies for capacity.
• Certifies the filter housing will hold up to the temperature and pressure claimed.

**About VOCs: From the NSF:  The category of VOC (Volatile Organic Chemical) includes a number of chemicals that are both man-made and naturally occurring. Water from wells and utilities may contain some of these contaminants. Some VOCs are pesticides, herbicides, or insecticides that seep into the ground water after application. Other VOCs enter the water supply through industrial or other waste disposal. This category also includes total trihalomethanes, which are a by-product of chlorination. ** Products certified for reduction of VOCs under Standard 53 will be effective for all of the following contaminants. alachlor atrazine benzene carbofuran carbon tetrachloride chlorobenzene  chloropicrin  2,4-D         dibromochloropropane (DBCP) o-dichlorobenzene p-dichlorobenzene 1,2-dichloroethane 1,1-dichloroethylene cis-1,2-dichloroethylene trans-1,2-dichloroethylene 1,2-dichloropropane cis-1,3-dichloropropylene dinoseb endrin  ethylbenzene  ethylene dibromide (EDB) haloacetonitriles     bromochloroacetonitrile   dibromoacetonitrile   dichloroacetonitrile   trichloroacetonitrile haloketones    1,1-dichloro-2-propanone   1,1,1-trichloro-2-propanone heptachlor epoxide hexachlorobutadiene  hexachlorocyclopentadiene  lindane  methoxychlor  pentachlorophenol simazine styrene 1,1,2,2-tetrachloroethane tetrachloroethylene toluene 2,4,5-TP(silvex) tribromoacetic acid 1,2,4-trichlorobenzene 1,1,1-trichloroethane 1,1,2-trichloroethane trichloroethylene trihalomethanes (TTHM) **bromodichloromethane **bromoform **chlorodibromomethane **chloroform xylenes Our note: Many web sites divide VOCs into lots of extra "categories" like: Pesticides, Herbicides, insecticides, Haloacetonitriles (HAN), Haloketones (HK), Trihalomethanes (THMs).  Don't let this confuse you - they are all VOCs.
