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 MB-F08 is Maxblue's aftermarket replacement filter sharing the same 2.7 x 7.5 x 12-inch form factor as other filters in this compatibility class. It sells for $26.99 for a 3-pack, landing at roughly $9 per cartridge. The NSF 42 and 372 certifications are dual-listed, covering both the reduction of chlorine taste and odor and confirmation that the filter materials comply with lead-free standards under NSF 372.
Maxblue positions itself as a budget-to-mid-range aftermarket filter brand. The MB-F08 listing does not provide a rated capacity or service life, which is a common gap across aftermarket filters in this category. The material field was not specified in available data beyond the NSF certification reference.
Buyer sentiment at 4.6 stars from 1,400 reviews is respectable. This review count provides enough signal to gauge typical fit and performance outcomes, even if it is smaller than some higher-volume competitors.

Performance notes
The MB-F08 is certified to NSF 42 (aesthetic impurities such as chlorine taste and odor) and NSF 372 (lead-free material compliance). NSF 372 confirms the filter housing and components are made from lead-free materials, which is a material safety standard rather than a performance certification. No NSF 53 or NSF 401 certification is present. Dimensions are 2.7 x 7.5 x 12 inches. No flow rate or gallon capacity data is available.
What buyers say
With 1,400 reviews averaging 4.6 stars, buyer feedback for the MB-F08 is positive. While the review count is lower than the top-volume filters in this segment, 1,400 ratings is enough to reflect real-world installation and performance experience. No bought-last-month data was available at time of review.

Frequently asked questions
What does NSF 372 certification mean on the MB-F08?
NSF 372 is a material standard that certifies the filter components are made with lead-free materials. It is not a performance certification for contaminant reduction. It means the filter body and internals should not introduce lead into your water, which is a separate concern from whether the filter actively removes lead from incoming water. For active lead reduction, look for NSF 53 certification.
Does the MB-F08 filter reduce lead in water?
The MB-F08 does not carry NSF 53 certification, which is the standard for lead reduction in drinking water. Its NSF 372 certification confirms lead-free construction materials, not lead removal from water. If your water supply has lead contamination concerns, a filter certified to NSF 53 for lead would be the appropriate choice.
How does the MB-F08 compare in price to OEM filters?
At $26.99 for 3 cartridges, the MB-F08 comes to about $9 per filter. Most OEM refrigerator replacement filters for comparable models sell individually for $20 to $50, making the MB-F08 a substantially lower per-filter cost. The trade-off is that OEM filters are made by the refrigerator manufacturer to their own specifications, while aftermarket options like the MB-F08 are made to match but carry separate third-party certifications.
