Buying Guide: How to Choose the Right Air Purifier

Room Size

Match the purifier’s CADR (Clean Air Delivery Rate) to your room size. Aim for at least 2/3 of the room’s square footage in CADR for effective cleaning. Running a purifier in a room larger than its rating produces minimal results.

Filtration Type

True HEPA: Captures 99.97% of particles 0.3 microns — standard for good purifiers
HyperHEPA (IQAir): Captures particles down to 0.003 microns — medical grade
Activated carbon: Essential for odor and VOC removal
Ionizer/PlasmaWave: Neutralizes biological contaminants — some produce trace ozone

Key Features

Auto mode: Adjusts fan speed based on real-time air quality sensor
Air quality indicator: Shows current air quality level
Wi-Fi/app: Remote monitoring and scheduling
Sleep mode: Very quiet operation for bedrooms

Operating Cost

Factor in filter replacement costs. True HEPA filters typically need replacement every 6–12 months. Check annual filter costs before buying.

Frequently Asked Questions

Do air purifiers actually work?
Yes, when properly matched to room size. True HEPA filters are scientifically validated to capture allergens, dust, pollen, mold spores, and some viruses. They significantly reduce airborne particulates.

Can an air purifier help with COVID?
HEPA filters capture particles the size of aerosols that carry viruses. While not a substitute for ventilation, a HEPA air purifier in an enclosed space reduces viral load in the air.

How long should I run an air purifier?
Continuously, or at least several hours per day. Air quality degrades quickly when the purifier is off. Most models have an eco mode that reduces fan speed when air is already clean.

Where should I place an air purifier?
Near the source of pollution (kitchen, pet area) or where you spend the most time (bedroom, living room). Leave space around all vents for proper airflow.
