📋 Table of Contents
1What room size should I match my air purifier to?
Look for a purifier rated for a space 1.5 to 2 times your room’s square footage. A 300 sq ft unit in a 200 sq ft room will run quieter and clean faster, while undersizing leads to poor air quality and motor strain.
2Does CADR matter more than filter type?
Yes — the Clean Air Delivery Rate (CADR) in m³/h tells you how fast it removes dust, pollen, and smoke. A CADR of 200-300 m³/h is ideal for average rooms, while higher values are needed for large or open spaces with heavy use.
3Are HEPA filters always the best choice?
HEPA filters capture 99.97% of particles 0.3 microns or larger, making them excellent for allergens and dust. For viruses or odors, look for an activated carbon layer in addition to HEPA, as HEPA alone won’t remove gases or VOCs.
4How often will I need to replace filters?
Most HEPA and carbon filters last 6-12 months depending on usage and air quality. Units with filter life indicators help avoid guesswork, and some models let you replace just the HEPA or carbon part separately to save money.
5Is a smart air purifier worth the extra cost?
Smart models with air quality sensors and app control offer convenience, but they’re not essential. If you prefer simplicity, a manual unit with a visible filter and basic fan settings can be just as effective with less tech to manage.
