Frequently Asked Questions
What does CADR rating mean?
CADR stands for Clean Air Delivery Rate and measures how quickly an air purifier removes particles from a room. A higher CADR means faster air cleaning. CADR 300+ is good for 200-300 sq ft rooms. CADR 600+ is needed for larger living spaces. Compare CADR to your room size to ensure adequate coverage.
Do I need a carbon filter?
HEPA filters alone capture particles (dust, pollen, dander) but not gases or odors. A carbon filter layer removes smoke, VOCs, cooking odors, and chemical pollutants. If you have cooking odors, smoke exposure, or chemical sensitivities, a carbon filter is essential.
What's the difference between H11, H13, and H14?
These refer to HEPA grades with increasing filtration efficiency. H11 captures 99.5%, H13 captures 99.95%, and H14 captures 99.995% of particles down to 0.3 microns. For most homes, H13 is sufficient. H14 is medical-grade and necessary only for severe allergies or immunocompromised individuals.
How often do I need to replace filters?
Most air purifier filters last 6-12 months depending on usage and air quality. Heavy use or poor air quality shortens filter life. Budget $80-$180 per year for filter replacements. Set a calendar reminder to check filter condition quarterly.
Are expensive purifiers really better?
Not always. Budget models ($100-$300) offer excellent value for small to medium spaces. Premium models ($500+) excel in large rooms, with design features, or specialized filtration (medical-grade, formaldehyde removal). Choose based on room size and your specific needs, not price alone.
