FAQ

How often should I replace my refrigerator water filter?

Most manufacturers recommend replacing the filter every 6 months or after 200 gallons of water use, whichever comes first.

Can I use a generic water filter instead of the brand-specific one?

Yes, as long as it is certified compatible with your refrigerator model. Always check the owner’s manual for approved filter types.

Why is there sediment in the water after installing a new filter?

Sediment may be from the water line or the new filter. Run water for 2 minutes to flush the system.

What if the filter doesn’t twist off easily?

Use a plastic filter wrench or gently tap the filter with a rubber mallet. Avoid using excessive force to prevent damage.

Can I replace the filter without turning off the water?

It’s safest to turn off the water supply to avoid leaks and water damage during installation.
