The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other water filtration: replacement filters, under-sink and reverse osmosis systems, filter pitchers, water dispensers, coolers, faucet filters and softeners we track in this category on price, popularity and size.

Overview
The PL-1100 is a Pureline single-unit refrigerator water filter designed for LG models including the LFX25974ST. It uses advanced activated coconut carbon block media, which is a widely used material in water filtration for its surface area and adsorption properties. The WQA (Water Quality Association) certification provides third-party validation of the filter's claims.
At $37.99 for a single filter, it sits at the higher end of third-party pricing. The coconut carbon block construction is a step up from loose granular carbon, generally offering more consistent contact time with the water. No capacity or rated service life figures are available from the spec data.
With 295 reviews at 4.7 stars, the sample size is smaller than some competing filters but the average is high. No monthly purchase data was available in the facts, suggesting intermittent demand rather than consistent volume.
Pros
- Advanced activated coconut carbon block media

Cons
- Single-pack only, no bulk option noted
- Priced at $37.99, higher than multi-pack alternatives
- Only 295 reviews, smaller confidence base than top competitors
- No rated capacity or filter life data available

Performance notes
The PL-1100 uses an advanced activated coconut carbon block, which is designed to provide consistent water contact and reduce aesthetic impurities such as chlorine taste and odor. WQA certification validates the filter's performance claims through independent testing. No specific NSF 42 or NSF 53 certifications are listed in the available data. Listed compatibility includes the LG LFX25974ST.
What buyers say
With 295 reviews at 4.7 stars, buyers report positive experiences, though the review base is modest. The high average in a smaller sample suggests mostly satisfied customers but offers less breadth of data than filters with thousands of reviews. Shoppers who need confidence on a specific LG model should verify compatibility directly.

Frequently asked questions
What LG refrigerators is the Pureline PL-1100 compatible with?
The PL-1100 is listed as compatible with the LG LFX25974ST. Pureline may list additional compatible models on their full compatibility reference. Always verify your exact LG model number before ordering, since LG uses multiple filter formats across its refrigerator lineup and using the wrong filter can cause fitment or leaking issues.
What is WQA certification and does it matter?
WQA stands for the Water Quality Association, an independent trade and certification organization that tests water treatment products against established standards. WQA certification means the filter has been independently tested to verify its performance claims. For shoppers, it adds a layer of third-party validation beyond manufacturer claims, similar in concept to NSF certification.
Why choose a coconut carbon block over other filter media?
Activated coconut shell carbon is valued for its high surface area and consistent pore structure, which can lead to more effective adsorption of chlorine and other aesthetic contaminants. Carbon block design also limits channeling, meaning water passes through the full filter media rather than taking shortcuts. These are design and material characteristics; actual performance depends on the specific contaminants present in your water.
