Understanding CADR and Room Coverage
CADR (Clean Air Delivery Rate) is the most important metric for comparing air purifiers. It measures the volume of filtered air delivered per minute. As a rule of thumb, you want a CADR rating that is at least two-thirds of your room's square footage. For example, a 300-square-foot room needs a CADR of at least 200 CFM.
Filtration Stages Explained
- Pre-filter: Captures large particles like dust, hair, and pet fur. Extends the life of subsequent filters.
- HEPA filter: Captures 99.97% of particles down to 0.3 microns (H13) or 99.995% down to 0.1 microns (H14). Essential for allergens, smoke, and bacteria.
- Activated carbon: Absorbs odors, VOCs, and chemicals. Weight matters—more carbon means better odor removal.
- PCO (Photocatalytic Oxidation): Uses UV light and a catalyst to break down VOCs and pathogens. Found in premium models like the AeroSense Pro X9.
Smart Home Integration
In 2026, most mid-range and premium air purifiers offer Wi-Fi connectivity and voice control. Look for support for your preferred ecosystem (Alexa, Google Home, Apple HomeKit). Advanced features like IFTTT integration, geofencing, and air quality triggers can automate your purifier based on your presence or external data (e.g., wildfire smoke alerts).
