Adjustable respirator regulator e-Free, designed for comfort and ease of use. The wearing comfort and safety of respirators have become crucial factors during this pandemic. The e-Free respirator regulator can adjust the tightness of the earhook respirator, freeing the ears from discomfort and eliminating earache caused by prolonged wear. This makes daily protection easier and more convenient. Pain points: 1. Ears bear all the pressure, leading to unbearable pain after a day. 2. The mask is loose, unable to provide effective protection. Product functions: 1. The ear rope does not touch the ear, preventing earache. 2. The mask fits better, providing more effective protection. Multiple gear options allow for adjustable fitting between the mask and face, distributing pressure evenly and achieving a comfortable fit. This is particularly beneficial for people who need to wear masks for extended periods. Advantages: 1. Large stress area, uniform pressure distribution, long-time wearing without discomfort. 2. Hook structure securely locks with ear rope, preventing separation. 3. 3D printing polyurethane elastomer material is skin-friendly, breathable, light, and easy to carry. 4. Four adjustable gears for most head sizes and shapes. 5. Strong and elastic, providing good coverage when wearing a hat. Weight: 12 grams. Note: * Only suitable for ear-mounted masks. * Children should be assisted by adults when wearing. * Can be reused after cleaning and disinfection.
