FAQ
How often should I replace the LT1000P?
The manufacturer says about every 6 months or 200 gallons, whichever comes first. Replace sooner if water flow drops.
Is the LT1000P NSF certified?
Yes. It is listed for NSF/ANSI 42, NSF/ANSI 53, NSF/ANSI 401 (source links below). Certification applies to specific reduction claims, and contaminants are not necessarily in all users' water.
Are cheaper aftermarket filters OK?
Some aftermarket filters carry their own NSF certifications (listed above), but certification doesn't guarantee fit. Some refrigerators, such as GE models using RPWFE, check for a chip in the genuine filter.
