Product review (1 stars): great 6 months of use, served very good, but new filters don't match with previous ones
UPDATE 10/18/2016: Okay folks, it has been confirmed that Samsung now redesigned their haf-cin / DA29-00020b filters. In the photos the one you see with Double rubber ring on the neck is the newest version.

Pros:
-Whoever had a leaking issue previously probably will no more have any leakage (even tho it wasn't the filters fault, it's your loose housing or wrong placement of filter).

Cons:
-now people who had no issues before may have issues now, not the leakage but your water flow will be extremely decreased
-if you are switching from the older version filter with single rubber ring to the double rubber ring new design, you will have to shut off the water valve, otherwise little bit of air will shut your new filter and it will no more work. once air pressure goes into the filter, paper changes it forms kind of gets damaged i guess.
-you will be so pissed due to double ring and change of design will decrease your water flow, so that means to take out the first 5 6 gallon of water will take hours!!!!

Conclusion, SAMSUNG NEEDS A NEW FILTER COMPANY OR REPLACE OUR EXISTING REFRIGERATORS WITH NEW ONE FOR FREE BECAUSE YOU LIKE MESSING UP EVERY YEAR WITH YOUR FILTER DESIGN!!!!

UPDATE 10/16/2016 ( I have been purchasing this same filter from Amazon, sold and shipped by) here is the latest one i just received 20 days ago and i was going to replace today, and just surprised that something was different!!!! Now there is a double rubber o-ring on the outer head of the filter??? Does Samsung making changes or what is going on??? I spent 2 hours to get a water flowing thru this filter, no luck. Not older filter doesn't work as well. I am afraid that this latest filter damaged my water filter housing head, I am returning for the replacement and will see if the replacement comes different or not.

Latest filter september 2016 looks the one with double rubber ring on the head part.
it looks little taller than what i have been using originally all the time (i always buy from amazon, shipped and sold)
also the filter's top head neck bottom (where its the body starts) looks different as well. Samsung needs to clarify if there are any changes or not on the filter!!!

Bought it at October 31st, it did fit, worked and served perfect. No leaks or other issues. Water runs fast and filters very well. I did some water tests between water coming thru this filter and coming straight from the tap. Filters and also softens the water little bit as well. Ensure the model type of filter in your refrigerator matches with this Da29-00020b as well so you will not have leaks or any other problems. 6 months of use 2 people, having visitors oftenly and we are really water drinkers. Just the filter light turned little bit purple now. So 6 months of life for a filter is actually pretty good.
