What to Look for in an Air Purifier
Before we jump into our top picks, let’s cover the essential features you should consider when shopping for an air purifier.
HEPA Filtration Technology
HEPA stands for High-Efficiency Particulate Air, and it’s the gold standard in air filtration. True HEPA filters capture particles as small as 0.3 microns with an efficiency rating that can reach up to 99.97%. Some advanced models even filter particles as small as 0.1 microns. This means they’re incredibly effective at trapping pollen, dust, mold spores, and even some bacteria and viruses.
When shopping, look for “True HEPA” or “H13 HEPA” filters rather than “HEPA-type” or “HEPA-like” alternatives, which don’t meet the same rigorous standards.
Room Size Coverage
This is crucial! An air purifier designed for a 200-square-foot bedroom won’t effectively clean your 1,500-square-foot living room. Check the manufacturer’s coverage area and consider the Clean Air Delivery Rate (CADR), which measures how quickly the unit cleans the air. Higher CADR numbers mean faster, more efficient purification.
Noise Levels
Nobody wants a purifier that sounds like a jet engine, especially in the bedroom. Modern air purifiers offer multiple fan speeds, with sleep modes typically operating at whisper-quiet levels (20-30 decibels). If you’re a light sleeper or planning to use it in a bedroom or office, prioritize models with low noise ratings.
Smart Features and Connectivity
Today’s air purifiers are smarter than ever. Many offer WiFi connectivity, allowing you to control them via smartphone apps, set schedules, and monitor air quality in real-time. Some integrate with voice assistants like Alexa and Google Assistant. While these features aren’t essential, they add convenience and help you optimize performance.

According to independent testing, it filters particles 700 times smaller than a human hair—that’s impressive!
The smart particle sensor is a game-changer. It continuously monitors air quality and automatically adjusts the fan speed when pollution is detected. Set it and forget it! The built-in sleep mode operates quietly enough for bedrooms, and customers rave about how it runs whisper-quiet on lower settings.
Real users have reported visible differences in dust accumulation after just a few days of use. One customer performed a side-by-side comparison with a more expensive brand and found the PuroAir 240 significantly more effective at reducing dust and allergens.
