Sears Kenmore 38476 Reverse Osmosis Replacement Filters (Whirlpool WHER 12 & 18 Compatible)

It's getting harder and harder to find these filters, but I still manage to find them. The RO membrane is starting to get even more harder. But otherwise, these here filters work great!

These are the filters that came with the original unit. The unit's almost 20 years old so it's good to find filters for this unit. The price is reasonable.

I would give these 5 stars except the bottom purple cap fell off of one of the filters and I was hesitant to use household glue to reattach, being it's a water filter. That made it a bit tricky to hold it in place while installing. I noticed by reading other reviews that this appears to be an ongoing issue. Other than that, they looked to be of the same construction as the originals and are doing the job. I would buy again.

These are for a very old RO filter for my kitchen. I could not have filtered water without these filters! Thank You!

Although not aware who the manufacturer was, preferred over the cheaper knock-off brand available on Amazon. Provided by and have done business with Water Filters Online, and will continue to do so.

Before I ordered these replacement filters for my Sears Kenmore UltraFilter 500 Reverse Osmosis under-sink water filtration system, I read through all the reviews about this product - and wondered if the competitors seeded the list with negative reviews to stop customers from choosing the cheaper product. There were many comments that, although being positive with 3-5 stars, said their water flow began to slow down and even stopped flowing completely, after 3-6 months. They wrote it as if to state that it was normal and expected - as it's recommended by all RO Water Filter companies to change out the filters every 6 months. But for all the decades I've owned and maintained RO filter systems, my water never stopped flowing or even slowed down - not once. That shouldn't happen - period. You may get dirty water, and the taste isn't as good as a new filter, but it shouldn't slow down or stop all together. That's just ridiculous. But I figured I would go ahead and save a few bucks and try out the cheap replacement filters for a change instead of buying the tried and true, top quality, most expensive Sears brand charcoal carbon bloc replacement filters like I usually do. So I received the order as promised. No critique in that regard. But when I began to read the package and literature, and then instructions, the first clue I had that these were of inferior quality, from a vendor/supplier that doesn't know squat about drinking water filtration systems, is the direction to place silicone sealant on the rubber gasket of the cartridge and cartridge housing to prevent leaks. I've owned multiple brands of under-sink Reverse Osmosis water filtration systems and I also have a whole-house filter inline just after my well storage tank in the basement - and they all say to use vegetable oil or other safe food-grade oil on the rubber gaskets. Not silicone sealant. I want to be able to remove the filter the next time I change it, don't you? And I don't want to drink silicone, do you? So then I removed the first cartridge from the plastic wrapping and following the instruction, I placed it in the empty housing and placed the housing under the faucet and turned on the water to medium-cold with a gentle pressure, (not fast, full-open), to flush it for the recommended minimum of five minutes. I picked up the filter by the top plastic end to rearrange it so the water would soak into it and noticed the plastic netting that is wrapped around the filter was immediately slipping and sliding out and off the filter. That has never happened with all the other replacement filter cartridges I've purchased (charcoal carbon bloc style). And furthermore, these are at least 5-10 cm smaller in diameter (just eye-balling it) as well as a good 1 or 2 ounces - (probably more) lighter than the Sears brand replacement cartridges that I usually purchase - granted for much more money. But there is truth in the phrase "you get what you pay for." Boy am I regretting this purchase! Coconut shell carbon????? What the heck is that? So I will go ahead and finish flushing the cartridge, and install it, but I will never buy this type of cartridge from this company, ever again.

I have been using these filter cartridges in my Kenmore RO system for some time and am totally happy with there performance. Much less expensive then the OEM units and fit perfectly. There are others out there but I landed on these and was satisfied and they do the job I needed, so I use them every time now!

Great customer service when original product shipped was broke (no one could have known till it was open). Emailed the company & had a new filter ASAP. Filter is great! Great quality. Could taste the difference in water asap.
