What Misconceptions Exist Surrounding CADR Ratings and Their Importance?
Several misconceptions exist regarding CADR ratings and their significance when selecting air purifiers.
- Higher CADR Always Means Better Performance: Many consumers believe that a higher CADR rating automatically equates to superior air purification. However, CADR measures the volume of filtered air delivered by the purifier and does not account for other important factors such as filter effectiveness against specific pollutants or the unit’s overall design and efficiency.
- CADR Ratings Apply Equally to All Types of Pollutants: Some people assume that CADR ratings are universally applicable across all types of air pollutants. In reality, CADR ratings are specific to three categories: smoke, dust, and pollen, and a high rating in one category does not guarantee high effectiveness in others.
- CADR Ratings Are the Only Factor to Consider: It is a common belief that CADR ratings are the sole determinant of an air purifier’s effectiveness. While they provide useful information regarding airflow, other factors such as filter type (HEPA, activated carbon), noise levels, and room size compatibility should also be considered for a comprehensive evaluation.
- All Air Purifiers Have CADR Ratings: Some consumers think that all air purifiers come with CADR ratings, leading to confusion in their selection process. However, not all manufacturers provide these ratings, and some purifiers may offer effective filtration without being tested for CADR, which can mislead buyers regarding their performance.
- CADR Ratings Are Consistent Across Brands: Many believe that CADR ratings are standardized across all brands and models. In reality, variations in testing methods and conditions can lead to discrepancies in ratings, making it essential to compare products carefully and consider user reviews and independent tests for a more accurate assessment.
