Frequently asked questions

Why should I invest in the Defender instead of other brands? 

The short answer: It’s scientifically proven to purify the air in your home, helping to improve your health and quality of life.

Designed for continuous operation, the Defender offers three simple settings—high, medium, and low—eliminating the need for complicated apps or settings that can fail over time. Just plug it in, turn it on, and enjoy breathing fresh, clean air.
