Always reduce exposure at the source first (turning off devices, unplugging, distancing). Shielding is a secondary step, not a replacement for basic reduction.

Measure before and after. Using an EMF meter helps verify whether shielding is helping or making things worse.

Work carefully. Over-shielding or partial shielding can sometimes reflect fields unpredictably. If unsure, professional consultation is advised.

Shielding technologies, when used correctly, can be a valuable tool for improving indoor air and energy quality, especially for those who are sensitive or living near unavoidable EMF sources.
