Purewell Replacement Water Filters Review Advanced 3-Stage Filtration Performance Tested

Description

Features

Using the Purewell PF-3 Black 3-Stage Composite Purification Elements (Item model number: K8012) has been quite an interesting experience. This filter is designed as a replacement for systems like ProOne® and Berkey® Big+ water filter systems. The three-stage filtration technology is impressive, combining a 0.01-micron hollow fiber ultrafiltration membrane, a silver ion barrier, and a high-density activated carbon block. This combination results in removing up to 99.9% of chlorine, rust, sediment, organic compounds, and heavy metals. It even meets NSF/ANSI 42 certification standards and the NSF/ANSI 372 lead-free materials standard, which gives me peace of mind about the water quality I’m consuming.

Technically, this filter has a remarkably small pore size of just 0.01 microns — a huge upgrade compared to the typical 0.2 microns found in many other brands. This translates to superior filtration precision and safer drinking water, something I noticed immediately after installation. The design fits perfectly within my existing Berkey system, and I didn’t experience any leakage, which is always a concern with replacement filters.

Ice Production Speed

Though the product is primarily a water filter, I tested the filtered water in my ice maker. The water flow rate was consistent, which directly impacted the ice production speed. The filter’s smaller pore size does slow water flow slightly compared to non-filtered water, but it’s not enough to cause frustration. Ice cubes formed at a steady pace, and the quality of ice improved noticeably since there were no odd tastes or odors. My family appreciated the cleaner, crisper ice in their drinks, especially during hot summer days.

Durability

The lifespan claims are substantial, with the Purewell PF-3 Black filters offering up to 6,000 gallons of water filtration per pair. I found this to be quite realistic based on my usage. After a few months of daily use, the flow rate remained strong, and the water quality showed no signs of degradation. Of course, this depends on the water source quality, but the filter feels robust and well-built. The activated carbon and hollow fiber membrane held up well under constant use. I did notice a slight reduction in flow near the end of the lifespan, which reminded me it was time to replace the filters.

Ease of Use

Putting the filter elements into my ProOne® system was a breeze. The design ensures a snug fit, and the manual’s pre-filtration instructions were clear, which helped prevent clogging issues. I appreciate that the manufacturer offers quick replacement support if any compatibility or performance problems arise. The compact size (2.7″ diameter by 8.6″ height) makes handling simple, and the filter fits well even in smaller countertop systems without taking up too much space.

One minor inconvenience is that the filter needs periodic cleaning to maintain optimal flow, but this is standard for most high-performance filters. Overall, the installation and maintenance process was straightforward, even for someone not particularly tech-savvy like me.

Ice Quality & Type

The water filtered through these composite elements produces exceptionally clear and odor-free ice cubes. Unlike some filters that leave a plastic or metallic taste, the Purewell PF-3 Black ensured the ice tasted fresh, almost like natural spring water. The fine filtration reduces impurities that commonly cause cloudy or off-flavored ice. I noticed this especially when serving iced beverages to guests — the difference was palpable and often elicited compliments.

Noise Levels

Since this is a gravity-fed water filter, noise isn’t a big factor here. However, I did observe the sound of water dripping as it filtered through the elements. It’s a gentle, rhythmic drip — nothing loud or annoying. For those using it alongside an ice maker or a water dispenser with a pump, noise levels might vary, but in my setup, it was pleasantly quiet.

Warranty

The Purewell PF-3 Black filters come with a risk-free purchase offer, including a free replacement service if clogging, slow flow, or odor issues arise. This warranty is reassuring, especially given the filter’s critical role in daily water consumption. I haven’t had to use the replacement service yet, but knowing it’s available gives me confidence in the product’s reliability.

Value for Money

The price point of these replacement filters strikes a balance between performance and cost. Compared to original brand filters for ProOne® or Berkey® systems, the Purewell PF-3 Black offers similar or even better filtration at a more affordable rate. Considering the advanced 3-stage filtration technology and the 6,000-gallon lifespan, this product feels like a smart investment. It’s a solid choice for anyone looking to maintain clean water without breaking the bank.

Product Comparisons

Compared to other popular replacement filters for gravity-fed water systems, the Purewell PF-3 stands out for its ultra-fine 0.01-micron pore size, which is notably smaller than many competitors’ 0.2-micron filters. This difference results in superior contaminant removal, especially for ultra-fine particles.

However, some competitors, like the original Berkey Black filters, have a slightly faster water flow rate. That said, the trade-off with Purewell’s finer filtration is worth it if you prioritize water purity. Another aspect where the Purewell filter shines is its NSF/ANSI certifications, which not all alternative filters hold.

On the downside, a few other brands offer easier cleaning mechanisms or longer warranty periods. Still, the performance and price of these composite filters make them a compelling alternative to standard options.

Advantages

• Advanced 3-stage filtration with 0.01-micron pore size ensures superior removal of contaminants
• Long lifespan of up to 6,000 gallons per filter pair saves replacement frequency
• Compatible with multiple popular systems like ProOne® and Berkey® Big+ series
• Certified by NSF/ANSI for safety and effectiveness

Disadvantages

• Slightly slower water flow compared to some original brand filters
• Requires periodic cleaning to prevent clogging and maintain optimal flow
• Replacement filters may not be sourced directly from original manufacturers, which might concern some users
• Not designed to reduce total dissolved solids (TDS), so some users might expect that feature

Using the Purewell PF-3 Black 3-Stage Composite Purification Elements has certainly improved the taste and safety of my drinking water and ice cubes. The advanced filtration technology and solid build quality make it a reliable component for my water system, though the slight reduction in flow speed and maintenance needs are factors to keep in mind. Family and friends have noticed the difference, and the affordability relative to other replacement filters adds to its appeal.
