Product review (2 stars): Shame on you Samsung
This filter is NOT worth the price asked. I ordered a replacement, and after installing it I dissected the original filter that came with our fridge. The attached images show how the filter is constructed. It is a simple activated charcoal cylinder with some very basic o-ring sealing, worth probably around $10 max. I estimate that about 65-85% of the cost of the filter is just profit.

Many companies play the same kind of pricing games for ongoing items, but I think it's deceptive, dishonest, and creates poor incentives for properly maintaining the appliance (which they probably want so they don't have to honor warranty claims). I despise these kinds of business practices, and refuse to cooperate.

Additionally, the 6 month replacement period is ridiculous unless your water supply is exceptionally contaminated. We are on well water and the only thing which needs to be removed is sediment (which is taken care of by a different filter system). The filter I dissected was used for 22 months, and based on what I found within I will now only be replacing the filter every 5 years or so.

Maybe others are happy to pay out the nose for very basic filtration, but I am not.
