How We Decided

In determining the best smart air purifier to buy, we explored efficiency, versatility, and digital controls for air purification.

In terms of efficiency, we are big fans of 3-stage filtration purifiers that use a pre-filter, true HEPA filter, and an activated carbon filter. If it includes a built-in germicidal UV-C light and ionizer, even better. Consider units with large square footage ratings (300 + square feet) and high CADR scores, which is indicative of the number of times the air is refreshed in a room. Don’t forget 360° air intake, intaking surrounding air from every direction for more even distribution, especially in open areas.

In terms of versatility, we look for units that can also double as style and prestige pieces, as well as offer multiple mounting options (standalone vs. wall mount vs. vertical or horizontal layout) to preserve space.

Lastly, we are big fans of true Smart features. In addition to the standard Sleep Mode and automatic mode for automatic fan speed adjustment based on output, we look for a dedicated smartphone app with Alexa and smart air purifier Google Home compatibility that offers real-time air quality monitoring insights using clearly depicted graphs and charts. All control functions should also be manageable in-app, especially useful in very large homes where purifiers are often out of reach.

Best Smart Air Purifier Buyer’s Guide

The Most Important Features to Consider

  1. Efficiency
    Look for smart air purifiers to carry a minimum 3-stage filtration (pre-0filter, true HEPA filter, and an activated carbon filter) along with a square footage rating of 300 square feet for best results. As a rule of thumb, the unit should have a larger square footage rating than the area you wish to cover. Our preference falls in line with high CADR (*clean air delivery rate scores for smoke, pollen, and dust.
  2. Versatility
    In terms of versatility, we are big fans of additional layers of defense to combat germs, primarily built-in germicidal UV-C lights and ionizers for extra power. These work by releasing negative ions into the atmosphere to bind and clump on captured airborne contaminants, effectively grounding them for a filter to sweep away.
  3. Digital Controls
    Go for smart air purifiers with a dedicated smartphone app that enhances the experience of controlling the unit. This includes adjusting multiple fan speeds, setting it to Sleep Mode (defaulting to lowest sound and speed setting), and understanding air quality with real-time updates using helpful graphs or a color-coded system. We are also big on a whisper-quiet operation that does not exceed 20 decibels.
