Best Samsung DA29-00020B (HAF-CIN) compatible refrigerator water filter for 2026. NSF/ANSI 42 + 53 certified, $16.99 vs $50 Samsung OEM. Fits 100+ Samsung french-door + side-by-side fridges.
[1]

What is the DA29-00020B?

The DA29-00020B is Samsung’s flagship refrigerator filter cartridge, in production since 2010. It’s a twist-in carbon block filter rated for 300 gallons / 6 months (whichever comes first). Samsung sells it under multiple product codes (HAF-CIN, HAF-CIN/EXP, DA97-08006A) but they all refer to the same cartridge.

Does my Samsung fridge use the DA29-00020B?

If your Samsung refrigerator was made between 2010 and today and isn’t a 4-door flex model from 2017+, the DA29-00020B almost certainly fits. Common compatible part numbers — any of these means DA29-00020B fits:

• DA29-00020B · DA29-00020A (current Samsung names)
• HAF-CIN · HAF-CIN/EXP (consumer brand label)
• DA29-00019A (legacy Samsung code)
• DA97-08006A · DA97-08006B (cross-references)
• Kenmore 46-9101 · 469101 (Kenmore equivalent)

If your fridge has a 4-door flex layout and the filter compartment shows HAF-QIN instead, you need our Samsung HAF-QIN Compatible. The two are not interchangeable.

Samsung models that use the DA29-00020B

OEM vs Compatible — what’s the real difference?

Installation in 90 seconds

1. Locate the filter compartment (usually upper-right interior of the fresh food section, behind a small flap).
2. Twist the existing filter counterclockwise a quarter turn.
3. Pull straight out — water shutoff is automatic, no leak.
4. Insert the new DA29-00020B Compatible and twist clockwise until securely locked.
5. Flush 1–2 gallons through the dispenser to clear air and carbon dust.
6. Reset the filter indicator: hold the “Filter” button on your fridge display for 3 seconds (varies by model).

Frequently asked questions

Will a compatible void my Samsung fridge warranty?

No. Federal law (Magnuson-Moss Warranty Act, 1975) prohibits manufacturers from voiding warranty just because you used an aftermarket part. Samsung can refuse warranty service only if the compatible filter caused the failure — essentially impossible for a passive carbon cartridge.

Is the DA29-00020B the same as the HAF-QIN?

No, completely different cartridges. DA29-00020B = older Samsung models (twist-in interior compartment). HAF-QIN = newer 4-door flex models 2017+ (different slot, different cartridge shape). Don’t mix them up — wrong fit = water leak.

How often should I replace it?

Every 6 months or 300 gallons, whichever comes first. A family of 4 typically hits 300 gallons in about 6 months exactly. Heavy water use (lots of ice + dispenser drinks) can shorten this to 4–5 months. More on filter timing here.

What contaminants does it actually remove?

NSF/ANSI 42: chlorine taste & odor. NSF/ANSI 53: lead (≥99%), mercury, asbestos, benzene, cysts, particulates. Doesn’t remove fluoride, sodium, dissolved minerals, or PFAS specifically (need NSF/ANSI 401 for PFAS — see our PFAS guide).

Quick decision by your LG fridge year

How to identify which one your fridge uses

Method 1 — read your existing filter

If you have an old filter in the slot, twist counterclockwise to remove. The model number is printed on the cartridge label (LT700P, LT800P or LT1000P). This is the fastest, most reliable method.

Method 2 — check your fridge model number

The model sticker is inside the fresh food compartment (usually upper-left ceiling or left wall). LG model numbers start with prefixes like LFXC, LFXS, LMXS, LSXS. Cross-reference:

• LT700P fits: LFXC24726S, LFXS29626S, LFXS29626W, LFXS30726S, LFX21976ST, LFXS24623S, LMXS30776S, LMXS30746S, LMXC24746S, LSXS26326S, LSXS26326B, LSXS26326W, LSXS26466S, LSSB2692ST, and 50+ other 2010-2014 LG models
• LT800P fits: LMXS30776S (later units), LMXS30746S, LMXC24746S, LSXS26326S/B/W (2014+ rev), LSXS26466S, plus Kenmore 9490 fits
• LT1000P fits: LMXS30796D, LMXC23796S, LMXC23796D, LMXS28626S, LFXC24796D, LSFXC2496D, LSXC22396S, LFXS30796S, LFXC24796S, LMXS30796S, LSXC22396D, LFXS30796D, and 50+ other 2017+ LG models including most InstaView and Knock-Twice models

Method 3 — visual inspection of the slot

The three filters have visibly different shapes:

• LT700P: short cylinder, ~6.875″ long, push-twist with no collar
• LT800P: longer cylinder, ~7″ with thicker housing, twist-lock
• LT1000P: longest, ~8″ with newer LG locking mechanism, used on InstaView models

Are LG filters Kenmore-compatible?

Yes. LG manufactures most refrigerators sold under the Kenmore brand (since 2009). The LG filter ↔ Kenmore mapping is exact:

• LT700P = Kenmore 9690 / 46-9690 / 469690
• LT800P = Kenmore 9490 / 46-9490 / 469490
• LT1000P = Kenmore 9980 / 46-9980 / 469980

You can buy either branded version — they’re identical inside.

Filter performance — are they all the same?

All three are NSF/ANSI 42 + 53 certified for chlorine, lead, mercury, asbestos and other standard contaminants. The LT1000P offers the most comprehensive coverage on some batches, with NSF/ANSI 53 + 401 certification for additional pharmaceutical and emerging contaminant reduction.

OEM vs Compatible — which to choose?

Genuine LG OEM filters cost $42–54 each. Our NSF/ANSI 42 + 53 certified compatibles cost $13.99–18.99. Same fit, same flow rate, same standard contaminant reduction. Annual savings per fridge: $58–72.

Pick OEM if: your LG fridge is brand-new and still under premium warranty, or you specifically need NSF/ANSI 401 (PFAS/pharmaceutical) coverage. Otherwise, the compatible is the smarter financial choice.

Are aftermarket compatible refrigerator water filters safe? The honest answer with science: how NSF/ANSI certification works, what to look for, and the marketing tricks to avoid in 2026.
[1]

The short scientific answer

A refrigerator water filter is fundamentally simple technology: water flows through a cylinder of compressed activated carbon. The carbon adsorbs (binds) chlorine, organic compounds, lead and other contaminants while letting water through. The OEM cartridge from Whirlpool, GE, Samsung, etc. uses exactly the same activated carbon as a generic compatible — often produced in the same Asian factories.

What differs between OEM and compatible:

• The plastic housing (must match the fridge slot exactly)
• The brand markup (OEM: 70-80% margin; compatible: 30-40%)
• Certification documentation (the OEM is always NSF certified; compatibles vary)
• Sometimes minor differences in micron rating or flow rate

What NSF certification actually proves

NSF International is an independent, accredited US lab (founded 1944, no government affiliation) that physically tests filters against published standards. To get certified, a filter must:

1. Pass live water tests — challenge water with known contaminant levels run through the filter, then measured at the output
2. Demonstrate measurable reduction per the standard (e.g., NSF/ANSI 53 requires ≥99.5% lead reduction from 150 ppb input)
3. Pass material safety — the housing plastic must not leach BPA, phthalates or other contaminants into your water
4. Be retested annually by NSF — pulled from real factory production lines

Filters that pass get an NSF certificate number you can verify at info.nsf.org/Certified/DWTU. Look up the manufacturer + model — if it’s not in the database, it’s not actually certified.

Marketing tricks to watch for

How to verify a compatible filter in 60 seconds

1. Look at the seller’s product page. Does it list specific NSF/ANSI standards (42, 53, etc.) with cert numbers — not just “NSF logo”?
2. Search the NSF database. info.nsf.org/Certified/DWTU → enter the manufacturer name → does the product appear?
3. Email the seller asking for the lab certification PDF. Reputable sellers send it within 24h. If they refuse or vanish, it’s a red flag.
4. Read the warranty. Real compatible sellers offer fit guarantees and return windows (we offer 365-day returns + $1,000 wrong-fit guarantee). Junk sellers offer none.

Will a compatible void my fridge’s warranty?

No. The federal Magnuson-Moss Warranty Act (1975) explicitly prohibits manufacturers from voiding your warranty just because you used a third-party part. Whirlpool, GE, Samsung, etc. can refuse warranty service only if they can prove the aftermarket filter caused the failure — which is essentially impossible for a passive filter cartridge.

Manufacturers love to imply otherwise in their marketing (“only OEM filters preserve your warranty”), but it’s a scare tactic. Read your warranty fine print — it almost certainly doesn’t actually require OEM filters.

When OEM is the right pick anyway

For most kitchens, NSF-certified compatibles are the smart financial pick. But there are 4 cases where OEM makes sense:

• RFID-aware fridges (newer GE Café, GE Profile post-2017 with XWFE) — the RFID handshake works only with chipped cartridges. Most reputable compatibles now also have RFID chips, but check the listing.
• Premium luxury appliances (Sub-Zero, Wolf, La Cornue) — manufacturer warranty terms can be stricter; OEM avoids any dispute
• NSF/ANSI 401 for pharmaceuticals/PFAS — most compatibles cover 42 + 53 only. If you specifically need 401-rated filtration, the OEM is often the only option
• Active warranty period — for the first 1–2 years on a brand-new fridge, sticking with OEM avoids any risk of warranty argument

Bottom line

NSF-certified compatible refrigerator filters are safe, effective, and represent the best value for 95% of US households. The 5% edge case where OEM matters: RFID-paired fridges, luxury brands under warranty, or specific PFAS/pharmaceutical filtration needs.

The risk isn’t “compatible vs OEM” — it’s “certified vs uncertified”. A $3 Amazon mystery cartridge with no NSF cert is genuinely dangerous and should be avoided. A $12-15 NSF/ANSI 42 + 53 certified compatible from a reputable seller delivers identical filtration to a $48 OEM. We sell only the latter.

The 60-second decision chart

Decision tree by fridge type

Step 1 — locate your filter

Most Whirlpool-family refrigerators have the filter in one of three places:

• Top right of the fresh food compartment (interior wall) → likely Filter 1, 4 or A
• Inside the door → Filter 2 or 3
• Bottom grille (front bottom of fridge) → Filter 5

Step 2 — read the cartridge label

Pull out your existing filter (twist counterclockwise, no water spills — automatic shutoff). The number printed on it tells you exactly which EDR you need. If illegible, look at the slot — the filter slot itself often has a “Filter X” label.

Step 3 — cross-reference your fridge model

If you can’t find an old filter and the slot has no label, your fridge model number (sticker inside the fresh food compartment, ceiling or door frame) maps to a filter. Email us your model at contact@discountfiltershop.com — we’ll tell you within 24h.

Why six different filters? It’s mostly business, not engineering

From a pure filtration standpoint, all six EDR cartridges use the same activated carbon block media and remove the same core list of contaminants. The reason there are six is fridge slot design — different generations of Whirlpool refrigerators have different slot geometries to lock you into branded refills. The cartridges themselves are nearly identical inside.

This is also why NSF-certified compatible cartridges work perfectly — the filtration tech is generic; only the plastic housing has to match the slot.
