They look alike, but what is the difference between models 531411 and 531418? Both are sold by Amazon.

I believe the 531411 is an old model with push button releases for the filters. The 531418 (which I have) uses twist filters and there is no button. Other than that, I think they are identical. I am happy with the 531418 (EZ RO4) so I suggest that model.

I purchased the 531418 model. Both models have similar capabilities and the fittings and installation are essentially the same. The only difference that I can see is that model 531418 has filters that twist on and off and model 531411 has filters that push on. A button on the housing is pressed to release the filters when it is time to change them. It seemed to me that the push button set up on model 531411 was more complicated and therefore had more moving parts that could fail over time. I believe model 531418 is the newer model. I am not sure why this company chooses to manufacture and market two different systems that are so similar. I purchased the 531418 model.

I'm not sure but you can go to Watts Premier website and get the phone number. They have a very helpful support groupe.

I believe it to be model # 4193. You should get this at this price. I paid $20 more. Good deal!

The one we are offering is the SDCC Shadow version. We have no idea why Amazon combined the two listings. we will contact them to get it fixed, thanks for letting us know.

Both are identical - we just have different fee structure on the Amazon listing thus we have it listed with different price -

It is the same one, just a different seller. To confirm this call amazon customer service and they describe and compare the items to you. They answer your phone promptly or e-mail.

I don't know the difference between the two--only that one is a newer model than the other. You should research the model numbers.

It is different than the one I got. I'm not sure of the year of either model.

Look on the site for others that look alike, I bought one for $3.00 and one for $11.oo and they are both the same. They both do the work.

It looks like 6194-1 has a picture on it. That seems to be the only difference..and the price of course. We are very content with the 6316-1 model. Does the job just fine.

When I searched the first part number, I came up with both numbers on amazon.com; the last one was about 3 times as much. I think that they are interchangeable.Sincerely, Wiley Henson

The one I ordered was no different. It just cost less! If there is difference, I am not aware of it.

They are the same unit. Minor cosmetic differences which I attribute to vintage variation. Not sure which company is the OEM.

No clue. Pictures online look identical. Suspect just a minor manufacturing change, but only guessing.

I compared models on the Samsung website. The 2 model numbers in question are shown with slightly different descriptions. However, I ordered the model in question and received the other. I don't think there is an actual distinction. The cover works fine.

That is the one I have. I don't know if it's the newer model, but I think that company offers different ones than the one pictured here.

Sorry, I don't know if there is a difference. Maybe the prices just vary. I would compare and make sure the model #'s are exactly the same, and if not, research the model numbers.

I'm in the same boat. I'm trying to decide between the 7411 & the 5914. I've seen the reviews, both seem to be good. It's my assumption that the 7411 is a newer model and it's only $20 more. Is it worth the extra or will the 5914 be just as good?
