Is the filtration effect of this refrigerator filter as good as that of the original one?

This refrigerator filter has passed NSF 401, 53, 42&372 certifications for perfect filtration effect. This filter can give you a better water purification experience at a lower cost.

The water is coming out dirty/gray after l installed the filter. Is this normal?

YES. You just twist and pull out the old one and insert the new one following instructions. You will need to run a gallon or so of water through (see instructions for filter in package) it before drinking the water again.

Why does the filter replacement indicator still stay on after installation of a new filter?

Most refrigerators require a manual reset. Please hold a reset key on your refrigerator for system resetting.

After installing a new filter element, the water flow rate is slower. What should I do?

Check to see if this is the correct filter for your refrigerator at first. Then flush 2-4 gallons of water through the filter. Our filter is made of activated carbon in uniform size from Sri Lanka, so it rarely happens.
