It indicates the volume of clean air an air purifier delivers per minute, specifically for three particle sizes: dust, pollen, and smoke. Higher CADR values mean faster and more efficient air cleaning.
When comparing air purifiers, focus on the CADR rating for the pollutants you’re most concerned about. AHAM recommends using the following formula to determine the appropriate CADR for your room size: (Room Area in sq ft) x (Ceiling Height in ft) / 60 = Recommended CADR. A purifier with a CADR lower than recommended won’t effectively clean the air in your space. Look for the AHAM Verified mark on air purifiers to ensure the CADR rating is accurate and independently tested.
Can humidifiers and air purifiers worsen allergies or asthma?
While intended to improve air quality, improperly maintained humidifiers and air purifiers can exacerbate allergies and asthma. A dirty humidifier can harbor mold and bacteria, releasing allergens into the air. Over-humidification can also promote dust mite growth, a common allergy trigger. Similarly, an air purifier with a poorly maintained or incorrect filter can recirculate pollutants instead of removing them.
To prevent this, diligent cleaning and filter replacement are crucial. For asthma sufferers, avoid humidifiers that produce warm mist, as warm, moist air can sometimes trigger symptoms. Consider an air purifier with a HEPA filter specifically designed to capture allergens. Maintaining humidity levels between 30-50% is also important, as both excessively dry and excessively humid air can irritate airways.
