If you are a Samsung refrigerator owner, you are likely all too familiar with the “Filter Warning” light. Every six months, like clockwork, that little red glow reminds you that you’re about to spend $50 on a piece of white plastic. While the official Samsung HAF-CIN/EXP (DA29-00020B) is a fantastic filter, the high cost has driven thousands of homeowners toward aftermarket options.
But here is the danger: Not all “compatible” filters are created equal. Some only remove the taste of chlorine, while others match the OEM’s ability to remove lead, mercury, and pharmaceuticals. If you are looking for the best generic replacement for Samsung DA29-00020B, you need to know exactly what is inside the carbon block. In this 1,500-word deep dive, we put Waterdrop, Glacier Fresh, and Pureza to the test.
💡 Mentor’s Fast Advice
If you want the highest safety rating (NSF 53), stick with Waterdrop Plus. If you live in an area with great city water and just want to remove that “pool water” chlorine smell for the lowest price, Glacier Fresh is the king of value. For a complete overview of all filters, specs, and troubleshooting, see our main guide.
The Science of Generic Filters: NSF 42 vs. 53 vs. 401

Before we look at the brands, you must understand the “Alphabet Soup” of certifications. If a filter doesn’t have these numbers on the box, it’s just a fancy straw.
- NSF 42 (Aesthetic Effects): This is the bare minimum. It means the filter removes chlorine, iron, and particulate matter. It makes the water taste good, but it doesn’t protect your health from heavy metals.
- NSF 53 (Health Effects): This is the “Big One.” This certification proves the filter removes Lead, Mercury, Asbestos, and Cysts. The original Samsung DA29-00020B is NSF 53 certified.
- NSF 401 (Emerging Contaminants): This is the newest standard. it targets “modern” pollutants like Ibuprofen, Naproxen, and pesticides that have seeped into the water table.
1. Waterdrop Plus (The Best Overall Replacement)
Waterdrop has effectively taken over the Amazon appliance space, and for good reason. They are one of the only companies that produces a generic DA29-00020B that actually matches (and sometimes exceeds) Samsung’s own filtration specs.
Filtration Performance
While Waterdrop sells a “Standard” model, their Waterdrop Plus line is the true winner. It carries NSF 42, 53, and 401 certifications. This means if you are worried about lead in your old pipes or agricultural runoff in your local water, Waterdrop Plus offers the same protection as the $50 OEM filter for roughly $18.
Fit and Finish
One common complaint with generic filters is the “Jackhammer” noise—a loud vibrating sound when you dispense water. This is caused by poorly machined intake valves. Waterdrop’s manufacturing tolerances are tight; their filters usually click into place with the same “satisfying” feel as the original Samsung cartridge.
Waterdrop Plus (3-Pack) – NSF 53 & 401 Certified
Why we love it: It is the only generic that takes your health as seriously as Samsung does. It removes lead and pharmaceuticals while saving you over $60 a year.
2. Glacier Fresh (The Best Budget-Friendly Option)
If you aren’t worried about lead—perhaps you live in a newer home with PEX plumbing or your city has a world-class filtration system—you don’t necessarily need an NSF 53 filter. You just want the “pool water” taste of chlorine to disappear.
The “Taste” King
Glacier Fresh filters utilize high-grade coconut shell carbon blocks. In blind taste tests, many users actually prefer the “crispness” of Glacier Fresh over the original Samsung. It is exceptionally good at removing odor and organic chemicals that cause that “musty” fridge smell.
Price per Gallon
Glacier Fresh usually wins on pure mathematics. You can often buy a 4-pack for the price of one single Samsung filter. This makes it the ideal choice for large families who go through a lot of ice and water and don’t want to feel guilty about changing the filter exactly every 6 months.
Glacier Fresh DA29-00020B (4-Pack)
Why we love it: It provides excellent tasting water for under $10 per filter. If you’re on a budget but hate the taste of tap water, this is your best bet.
3. Pureza / PurePlus (The Best for High-Pressure Areas)
Pureza (often branded as PUREPLUS) has a massive following among DIYers who have struggled with leaking generic filters in the past. Their “claim to fame” is their O-ring technology.
O-Ring Resilience
As we’ve discussed in our guide on diagnosing a Samsung fridge leaking after a new water filter, the black rubber O-rings are the main point of failure. Pureza uses a slightly softer, more pliable rubber than Waterdrop or Glacier Fresh. This allows the filter to create a seal even in older refrigerator manifolds that might have slight scratches or wear.
Filtration Middle Ground
Pureza typically falls in the middle. They are NSF 42 certified (taste/odor) and NSF 372 (lead-free material). They provide reliable, clean-tasting water with a very low failure rate regarding leaks or “stuck” filters.

The “Grey Water” Warning: Why You Must Flush Generic Filters
One reason homeowners leave bad reviews for generic filters is that the first few glasses of water come out looking like grey sludge or “ink.”
This isn’t a defect. All carbon filters contain “carbon fines”—tiny particles of dust created during shipping as the carbon block vibrates. Genuine Samsung filters are pre-flushed at the factory more aggressively than generics. When you buy a generic replacement, you must dispense at least 4 gallons of water before drinking. This clears the dust and ensures the water is clear and the taste is neutral.
