Buying Guide: best air purifier for a house
Room Size and Coverage Area
Calculate your room’s square footage and choose a purifier rated for at least that size. Models with higher CADR ratings clean air faster and handle larger spaces more effectively.
Filtration Technology Types
True HEPA filters capture 99.97% of particles 0.3 microns and larger, while activated carbon handles odors and gases. Some models add UV-C light or ionization for additional purification layers.
Noise Levels and Sleep Modes
Check decibel ratings, especially for bedroom use where quiet operation matters most. Sleep modes typically reduce fan speed and dim displays for nighttime comfort.
Smart Features and Controls
WiFi connectivity enables remote monitoring and scheduling through smartphone apps. Voice control compatibility with Alexa or Google Assistant adds convenience for hands-free operation.

Continuous operation maintains consistent air quality and prevents pollutant buildup. Most modern units use minimal energy and include auto modes that adjust based on air quality.
