Product review (1 stars): Before purchasing call Samsung!!!
If you really read the description in the ad, it says these particles are  NOT removed. You must read very carefully to catch the word -not-.
I purchased from the batch before this, that advertised the removal of fluxotine, (Prozac), ibuprofen (anti-inflammatory), progesterone (hormone), and Trimethoprin (antibiotic). From the
water.  Really? Oh, and it was not authorized for sale in Calif.  Really? I went to SEARS in CA. , and they were selling the same, exact product. FAKE.
This new batch, according to Samsung is not authorized for use in their refrigerators either. In fact, if you use any filter not bought directly from Samsung or an authorized dealer and have any problems - the warranty is cancelled.  Isn't SEARS an authorized dealer?  Home Depot, etc., apparently not. Amazon's and SEARS both said "Genuine Authorized Samsung Filter".  Well, they weren't.  I'm out the purchase money.  I could have had water damage to my home costing thousands and Samsung would have denied the claim.
Who protects the consumer from these FAKE , Authorized Genuine products?  Buyer Beware!!!
Before purchasing, call 1-800-SAMSUNG.  I spent almost an hour with them on the phone today myself.
