Why an Air Purifier Is a Smart Tech Upgrade
Protection Against Pollution and Allergens
Indoor air can be just as polluted (or worse) than outdoor air. Air purifiers with True HEPA (H13/H14) filters can trap particles as small as 0.3 microns — dust, pollen, smoke, and even some bacteria. This is crucial for allergy sufferers, pet owners, and city dwellers.
Clean Air Delivery Rate (CADR)
CADR measures how quickly an air purifier cleans the air. A higher CADR means faster purification — use the “two-thirds rule”: smoke CADR should be at least two-thirds of your room’s area (in sq ft).
Continuous Use Efficiency
Because purifiers are most effective when run continuously, look for models with low-decibel night modes and efficient power consumption for long-term use.
Filter Maintenance
HEPA + activated carbon filters require periodic replacement — typically 8–12 months depending on use. Factor filter cost and availability into your decision.
Smart Features & Automation
Many modern purifiers include AQI sensors, auto modes, app control, and voice assistant support — features that keep indoor air healthy with minimal manual input.
