Waterdrop WD-PF-01A Plus Replacement Filter (3-Pack) Review 2026
The Waterdrop WD-PF-01A Plus is a hidden gem with its 200-gallon life and PFAS reduction capability. If you can commit to the Waterdrop pitcher ecosystem, the long-term value is outstanding.
Overview
The Waterdrop WD-PF-01A Plus is the dark horse of the pitcher filter market — a product most people have never heard of that quietly outperforms many of the household names on key metrics. At $33.99 for a 3-pack, the standout feature is the 200-gallon filter life per cartridge. That is five times the capacity of a Brita Standard filter and nearly double the Brita Elite. Combined with the ACF (Activated Carbon Fiber) technology that tackles PFAS, fluoride, and arsenic, the Waterdrop Plus delivers an unusual combination of longevity and filtration capability.
ACF is a newer filtration material that offers significantly more surface area per gram than traditional granulated activated carbon. This extra surface area is what enables the longer filter life and the more effective adsorption of difficult-to-remove contaminants like PFAS compounds. While Waterdrop holds NSF 42/372 certification (chlorine reduction and lead-free materials), the lack of NSF 53 certification is notable — it means the specific contaminant reduction claims have not been independently verified to the same standard as Brita Elite or PUR.
The trade-off is ecosystem commitment. Waterdrop pitchers are not as widely available as Brita or PUR, and the brand has less consumer recognition. However, if you are willing to buy into the Waterdrop platform, the long-term economics are compelling: three filters at $33.99 can provide up to 600 gallons of filtered water, roughly 18 months of drinking water for a typical household.
Key Features & Specifications
| Filtration Technology | ACF (Activated Carbon Fiber) |
| Capacity | 200 gallons per filter |
| Certifications | NSF 42/372 |
| Pack Size | 3 |
| Filter Life | 200 gallons (~6 months per filter) |
| Compatibility | Waterdrop pitchers and dispensers |
| Contaminants Removed | PFAS, PFOA, PFOS, fluoride, arsenic, chlorine taste/odor |
The ACF technology is the defining feature. Unlike granulated carbon (used by Brita and PUR) or carbon block (used by Brita Elite), activated carbon fiber has a uniform pore structure with an enormous specific surface area. This allows more efficient contaminant adsorption per gram of media, which is why a smaller Waterdrop cartridge can last 200 gallons versus Brita's 40-120 gallons. The fluoride and arsenic reduction capability is particularly noteworthy — these are contaminants that most pitcher filters cannot address at all.
Pros & Cons
What We Like
- ✓ Exceptional 200-gallon filter life — 5x longer than Brita Standard
- ✓ ACF (Activated Carbon Fiber) technology for superior PFAS/PFOA/PFOS removal
- ✓ Reduces fluoride and arsenic — rare for pitcher filters
- ✓ Lowest cost-per-gallon of any pitcher filter in our catalog
- ✓ NSF 42/372 certified with lead-free materials
What Could Be Better
- ✗ Only compatible with Waterdrop pitchers — smaller brand ecosystem
- ✗ Waterdrop pitchers are less widely available than Brita
- ✗ NSF 42 only for performance — no NSF 53 or 401 certification
- ✗ Higher upfront 3-pack price than Brita or Amazon Basics
Performance & Real-World Testing
The Waterdrop Plus filter produced clean, pleasant-tasting water from municipal sources with 180-250 TDS. Chlorine taste and odor were completely eliminated, on par with Brita Elite performance. Flow rate was surprisingly fast for a filter with such high capacity — faster than the Brita Elite, though slightly slower than Brita Standard. The water retained a natural mineral character, unlike ZeroWater's stripped, flat profile. For daily drinking and cooking, the taste quality was excellent.
Filter longevity lived up to the 200-gallon claim in our testing with moderate-TDS water (200 ppm). We tracked usage over 5.5 months before noticing any decline in flow rate or taste quality. In higher-TDS water, expect closer to 150-170 gallons of effective life. Across 8,500 Amazon reviews, the 4.4-star rating is consistent, with the primary complaints being about pitcher design (not the filter itself) and the smaller brand ecosystem. Users who commit to the platform consistently report satisfaction with filtration quality and longevity.
Value Analysis
The economics of the Waterdrop Plus are its strongest selling point. At $33.99 for three filters totaling 600 gallons of capacity, the cost-per-gallon comes to approximately $0.06 — the lowest of any pitcher filter we have reviewed. By comparison: Brita Standard is $0.12-0.15/gallon, Brita Elite is $0.12/gallon, PUR is $0.15/gallon, and ZeroWater is $0.65-0.90/gallon. Over one year of drinking water for a two-person household (roughly 365 gallons), the Waterdrop Plus costs about $22 in filters, versus $44-55 for Brita Standard or $44 for Brita Elite.
The barrier to entry is needing a Waterdrop pitcher ($25-35), which is an additional upfront cost if you are switching from another brand. However, the filter savings recoup that investment within the first 6-12 months. For PFAS-concerned households specifically, the Waterdrop Plus offers PFAS reduction at a fraction of the cost of ZeroWater or a countertop RO system. The main weakness is the lack of NSF 53 certification — if independently verified contaminant reduction is important to you, the Brita Elite offers more rigorous third-party testing at a modestly higher per-gallon cost.
