Water Filters made Easy At![]() |
| |||
| I need to replace an old Waterpik IR-10A filter system for under our kitchen sink. Quality wise does anyone know if a Culligan filter system is better than a Whirlpool filter system? I am looking at the Culligan EZ-4 or the Whirlpool WHED20 or the 3M Filtrete 3US-PS01 (similar to the Whirlpool WHCF-SUF). I noticed that the EZ-4 only has one filter but the WHED20 has two filters? Does one do a better job than the other? Thanks. |

| As with most responses to water equipment questions, there are two issues that need to be understood. First, what are the conditions of the water you wish to treat, and secondly, what are the objectives you wish to achieve through water treatment? Are you on city or well water? Have you had your water tested? If so, what are the results? Do you currently have any other water treatment equipment? How many people would be using the equipment? Moreover, the quality of the equipment is reflected both by your level of seriousness to improve conditions and your knowledge of the benefits (and shortcomings) of any equipment that you would be considering. Finally, and perhaps most importantly is VALUE. Going cheap can be very costly... There can be am enormous difference from bargain basement varieties to excellent, high quality equipment. The Culligan EZ-4 is a carbon block filter specializing in removing VOCs (volatile organic chemicals) and a host of other contaminates that most C-block filters can do. It is certified with NSF. The Whirlpool WHED20 offers similar quality but has a lovely faucet. They can also set you up with a reminded to change filters. Culligan may also offer this service. From what I know the 3M Filtrete 3US-PS01 is offered at Lowe’s and a faucet can be added. Most filter changes are recommended at 6 months with these systems, but this is a guessing game as no one uses the same amount of water. There are metered filters out there that are designed by the number of gallons used rather than some arbitrary time period. Personally, I prefer reverse osmosis to simple filtration systems for drinking water systems. Let us know. Andy Christensen, CWS-II Last edited by awc222; July 17th, 2008 at . |

| Thanks for the information. We are on a municipal water system with pretty good water. The filter is mostly to filter out the chlorine taste. Would it be safe to say since all three of these filters have the same certification from NSF they should all perform about the same? Thanks |

| Generally, speaking, yes, they will work the same. There may be subtle differences in flow rate and service life. NSF has many different catagories in their ratings. Make sure the NSF numbers are the same. Go to nsf.org and search for specifications. Andy Christensen, CWS-II |
