Cellphones use EMF waves that are a combination of radiowaves and microwaves for transmitting data for texts, calls, and even web browsing. Being exposed to EMF radiation for longer periods can be harmful and result in health complications in the long run. Hence, shielding the phone with coverings made from a material that can block excess radiation is important. Herein, we discuss some of the best anti-radiation cellphone case brands in the market: SafeSleeve The wallet-style anti-radiation cell phone cases from SafeSleeve feature a front flap made from radiation blocking material. Certified by the Federal Communication Commissions (FCC), these cases block radiation while you make or receive calls. Apart from EMF-blocking materials, SafeSleeve anti-radiation cell phone cases are also made from shock-absorbing materials that can protect the phone from damage due to accidental falls. The brand claims that it offers 92% protection against ELF (Extremely Low Frequency) and 99% protection against RF radiation. RadiArmor Just like SafeSleeve, RadiArmor is a brand that makes wallet-type anti-radiation leather phone cases.
