An air purifier improves indoor air quality by removing dust, allergens, and pollutants. True HEPA filters capture 99.97% of particles down to 0.3 microns. Check the Clean Air Delivery Rate (CADR) and match it to your room size. Noise level matters in a home office -- look for models under 40 dB on low settings. Factor in ongoing filter replacement costs when comparing prices.
