Review Analysis Results
Analysis Summary
The review set shows mostly legitimate characteristics with some minor concerns. Positive aspects include: natural variation in ratings (5★ to 2★), specific usage scenarios (HVAC systems, wildfire smoke, DIY filters), and authentic-sounding details (dented packaging, installation instructions). Concerns include: high proportion of verified purchases (15/16), repetitive praise of 'good price' across multiple reviews, and some generic phrasing. However, the presence of negative reviews, detailed installation advice, and varied writing styles suggests predominantly genuine feedback. The moderate confidence reflects the high verification rate but balanced by authentic content diversity.

Understanding This Analysis
What does Grade B mean?
This product has good review authenticity with minor concerns. While most reviews appear genuine, we detected some patterns that warrant mild caution.
Adjusted Rating Explained
The adjusted rating (4.10 stars) represents what we estimate this product's rating would be if fake reviews were removed. This product's adjusted rating is lower than Amazon's displayed rating (4.47 stars), suggesting positive fake reviews may be inflating the score.
How We Detect Fake Reviews
Our AI analyzes multiple factors: language patterns (generic vs. specific), reviewer behavior (history, timing), temporal anomalies (review clusters), verification status, sentiment authenticity, and statistical outliers. No single factor determines a review is fake - we look at the combination of signals.
Important Limitations
No automated system is perfect. Sophisticated fake reviews can evade detection, and some genuine reviews may be incorrectly flagged. Use this analysis as one data point in your purchasing decision, not the only factor. Reading actual review content yourself is always valuable.
