FAQ

What causes poor indoor air quality?

Common culprits: dust, pet dander, mold, VOCs from paint/furniture, cooking fumes, cleaning products, and poor ventilation.

How can I test my indoor air quality?

Use an air quality monitor (like AirThings or Temtop) to measure PM2.5, VOCs, CO2, and humidity levels in real-time.

Do houseplants improve air quality?

Minimally. While plants absorb some VOCs, you’d need hundreds of plants to match the effectiveness of a single HEPA air purifier.
