Samsung DA29-00003G (HAF-CU1) Filter: Which Replacement Is Certified for Lead?

Buy the Water Specialist WS611B-A. NSF lists it for lead and cysts. It costs $8.66 a filter on Amazon today, against $43.40 a filter for Samsung's own. Samsung's own DA29-00003G is also NSF-listed. Copies listed for taste and odor only are cheap, but they are not tested for lead.

Every DA29-00003G replacement we checked

"Certified for" comes from the certifier's own listing, not from the box or the Amazon page. Per filter = the pack price divided by the filters in the pack. Per year = 2 filters, because the filter is changed every 6 months.

Which Samsung filter do I have?

DA29-00003G, HAF-CU1 (HAFCU1/XAA) and HAFIN2/EXP are the same Samsung filter. The part number is printed on the old filter and in your fridge manual.

HAF-CIN (DA29-00020B) and HAF-QIN (DA97-17376B) are different, newer filters. This page does not cover them.

Waterdrop Plus WDP-F11B is on NSF's list for lead, but the Amazon listing we found names other codes (WD-DA29-00003G), so we do not give it a buy button.

Common questions

Is the Samsung DA29-00003G NSF certified?

Yes. NSF lists Samsung's DA97-06317A, whose replacement number is DA29-00003G (also HAFIN2/EXP), for NSF/ANSI 42, 53 and 401, rated 300 gallons.

Is HAF-CU1 the same as DA29-00003G?

Yes. HAF-CU1 (HAFCU1/XAA) and DA29-00003G are Samsung's two names for the same filter on Amazon.

Is this the same as HAF-CIN or HAF-QIN?

No. Those are newer, different filters. See HAF-CIN vs HAF-QIN or the Samsung filter page.

Are Waterdrop, AQUA CREST and PUREPLUS copies certified for lead?

It depends on the code. NSF lists Waterdrop WD-F11B, AQUA CREST AQF-FF11B and PUREPLUS PP-RWF1100A for taste and odor only. The versions listed for lead are Waterdrop Plus WDP-F11B, AQUA CREST AQF-FF11B-D and PUREPLUS PP-RWF1100AH.

Does the GLACIER FRESH GF-03G have a listing?

We found no NSF or IAPMO R&T listing for GF-03G.

How often should I change it?

Every 6 months, or after 300 gallons, whichever comes first. That is 2 filters a year.
