Earmuffs provide three main benefits: 1. Ear protection: The earmuff tip is made of soft, flexible plastic to help protect the ear. 2. Probe protection: The ear contacts the earmuff instead of the probe, reducing direct contact during cleaning and helping extend the life of the ear thermometer. 3. Hygiene: Using individual earmuffs for each person helps reduce the risk of cross-contamination. Each earmuff can be used up to 10 times. However, for hygiene purposes, it is recommended to replace earmuffs regularly, similar to replacing a toothbrush. It is advisable to keep extra earmuffs on hand as they do not have an expiration date.
