Question & Answers

Q Do these filters remove phthalates from the water?
A While this isn't on the list we arent able to confirm if it does or not. We recommend contacting Whirlpool directly @ 866-698-2538
Q i have the wher25,,,,when do I sanitize the system...before replacing all three filters or after replacing the filters?
A You can sanitize anytime the water starts to taste "Musty". You do not have to change the filters, as the contamination, (post Clhorine removal) is in the waterlines after the filters, and the tank. So, follow the manufacturer's instructions, and sanitize anytime you wish. Don't forget to make sure you run the faucet open for 24 hours after sanitizing to clear out ALL Chlorine from "Post Filter" lines and tank. When I sanitize is after changing filters, (only when water tastes funny, after changing filters). You might find it useful to change the RO filter, if sanitizing does not get rid of funny, (musty), taste. Then, sanitize again. Good Luck!!
A After - During. The purpose is to sterilize the system after you risk introducing any bacteria into the system by replacing the filters.
Q Are these the correct replacement filters for a Whirlpool reverse osmosis model WHER25, WHEERF5 two pack and WHEERM5?
A Yes, the WHEERF are the pre and post filters and the WHEERM is the membrane for the WHER25 system.
Q is this compatible with the Kenmore Ultra 450 unit?
A I am unfamiliar with that unit. But brief research seems to indicate that it is. Check with Waterfilters fast and make sure that you can return them if they don't fit. Good Luck.
A Yes, the Whirlpool WHEERF is compatible with the Kenmore Ultra 450.
Q do you still carry the wher25 R O filters as a set of three?
A The pre & post filters come as pkg of 2. The membrane filter comes as a single filter.
Q My units have a catalog #WHEERM & WHEEDF ..... are they still available?
Q can these be recycled?
A Most water filters cannot be recycled. Whirlpool may be able to give you recommendations regarding recycling. They can be reached at 866-698-2538
Q Hi, I have a whirlpool undersink WHER25 water filtration system. I belive these are the correct replacement filters for the WHER25. The yellow light was flashing and I know I need to replace the pre and post filter, but I can wait about 1 yr from date of purchase to replace the 3rd reverse osmosis cartridge. Is that correct? thank yo for your reply. Margaret Gryason
A That's generally correct, although under certain circumstances (water quality) a more frequent replacement may be necessary; for example, if performance of the unit declines.
A Hello Margaret, As I recall from my research the time to replace the 3rd cartridge depended on how often you changed the pre and post filters and the the amount of chemicals like chlorine in you water. I am at two years now and I haven't changed the osmosis cartridge because the water tastes fine.
A Yes, the WHEERF is the correct filter replacement set for the WHER25 and to be replaced about every 6 months. The WHEERM is the RO Membrane that is typically replaced every year/ once a year.
Q They do not distinguish between post filter and prefilter , are they the same filter and does it mater wich one goes in line first .?
A It does matter which goes in first as the first cartridge turn on and off the system.
A Same filter. I think I take them off left then right and replace them right then left. It is nice that you don't have to turn off the water.
A They are the same filter. According to owners manual remove prefilter cartridge then remove post filter cartridge. Install new cartridges in reverse order.
A No
A The Post and the Pre-Filters are exactly the same filters - no difference at all. Therefore, it does not matter which filter goes in first.
Q I have whirlpool ultraease reverse osmosis , need to replace 3 filters, 2 of 7276327 and 1 of 7276335 , I am wondering which one will be for the single 7276335?
A Model: WHEERM Reverse Osmosis Membrane.
A The 7276335 is one that shouldn't have to be replaced nearly as often as the other two. It's not really a filter but some kind of membrane. We had never replaced ours the three years we had that system.
Q Will this also replace filter number 7276327? This filter is also for a Reverse Osmosis system (WHER 25).. Thanks
A Yes, the individual filter part number for the filter in known as 7276327 and the set part number is also known as 7296830.
Q If my system is putting out only a little over a glass of water at a time, what does that mean?
A I should add mine is an EcoPure 30 system, the cartridges appear identical (awaiting an answer on if they are compatible)
A The cause of your problem could be a combination of a few things. When was the last time you changed your filters? Depending on inlet water quality and usage filter change may be required as frequently as once every 3-4 months. Most often required every 6-12 months. Be sure the 2 filters & membrane cartridges are installed in the correct location. The #1 cause of your issue is the tank. First turn off the supply valve. Drain the system. Remove the tank. Hold tank upside down to completely drain it. You will probably have to shake to get all water out. Get a digital tire pressure gauge. Unscrew the blue cap and check the pressure of the tank. It should read minimum 6psi max 10psi. If there is no reading, this is your problem, pump up the tank with air pump to 8 or 9 psi. If you didn't drain the tank completely a little water may shoot out of nipple on top of tank. That is normal. DO NOT OVERPRESSURIZE TANK! You will destroy the bladder inside if you do. While you hae the tank disconnected put a few drops of hydrogen peroxide in the tank to sanitize it. Hook back up & you should be good to go. If you have new filters, the tank is pressurized properly, and the system still not working then the RO membrane may be shot. They normally last 8-10 years with regular filter changes.
A Your house water pressure is low or maybe your RO tank isn't filling? I never had it happen.
A My thought would be you have some blockage somewhere. Are all your water lines going into and out of your filters free of kinks or pinching? How is your water pressure elsewhere? Also have you replaced the 3rd filter lately?
A Karan, You probably have a problem with your storage tank. The tank has a rubber bladder which is compressed as the system stores the processed water. When you turn on the faucet, the bladder expands, forcing the water out of the tank. If the tank or the bladder are defective, you will not have the maximum amount of water stored under the proper pressure. Sounds like your bladder needs to be repressurized. Some tanks have an air valve similar to a bicycle tire for the purpose of properly inflating the bladder. Hope this helps.
A When my system does that, it usually means that you need to replace the filters. Just to be on the safe side, I replace all of them at once just so I don't have to guess which specific one to replace. Once I do that, and flush the system (run it for about 1/2 hour), it runs very well.
A Storage tank air pressure charge could be less than that specified. It should be between 5-7 psi with the tank empty.
A You need new filters. If the filters have already been replaced, I would get a knowledgeable person to make sure the installation is correct.
A It probably means you need to change filters... that's what I did when mine "slowed down" and then the outputwent back to normal hope this helps
A I would of course change all the filters first, if you havent recently. If that does not help then you might need to look for a line restriction of some sort.
Q There are two filters in this pack, with two different codes, 12243 and 12244. Which is the upstream and which is the downstream filter? The original filters that came with the product were both code 11167.
A Each filter has a different code. The 12243 is the prefilter and the 12244 is the post filter.
Q The picture shows two filters and our WHER25 uses 3 filters. Which filter is the 3rd filter?
A The third filter is the RO membrane. It only needs replacement after a minimum of 5+ years. The two filter replacement pack (carbon block filters) is what you need to replace every 6months to a year depending on use & water quality.
A I think one of the filters is your reverse osmosis (RO) which doesn't have to be changed as often. The recommendation is every six months for these pre- and post- filters. The RO only needs changing when it gets clogged up which shouldn't be but every few years if you have a relatively clean source.
A The WHEERM RO Membrane is the 3rd filter for the WHER25 System. It is listed below under Related Products, Parts & Accessories.
