Product review (1 stars): 5 Gal water run and still particles in the water
Filter installation was easy. But when I run water, it came with dust-like and hair-like particles. Ok, I understand,  I have to run more water. 1 Gal later nothing changed.

 I remembered "Great Customer Service" from the product description. Unfortunately there's no phone number to call. On the manufacturer's web site there's no phone number too, just email. My email was answered instantly with the advice to run2 more gallons.

Ok, now after 4 more gallons I don't see a dust, but still occasional hair-like(or worm-like) particles. I made a 1 min long video showing what I have in the water. Unfortunately can't upload it here, so I just made screen shot. Enjoy.
