Ohropax Filter Flight earplugs provide effective noise reduction and pressure regulation during flights. These silicone earplugs feature patented filters that equalize pressure changes in the cabin during takeoff and landing while offering a pleasant level of sound insulation that still allows for conversation. Each package contains two pairs of earplugs in different sizes: standard size (M: 8-12 mm) with pre-installed filters and a smaller size (S: 6-11 mm) for users with narrower ear canals or children from elementary school age. The earplugs are made of two components: colored round filters and transparent silicone tips. For optimal performance, gently pull the earlobe upward and away from the head when inserting until the earplug fits comfortably and seals the ear canal completely. Remove the earplugs with a slow, twisting motion to avoid potential eardrum damage. The filters can be transferred between earplug sizes by gently pressing under the filter until it detaches, then inserting it into the other earplug with the ear symbol facing outward. Correct filter placement is crucial for certified noise reduction performance. Made from washable silicone material, these reusable earplugs provide lasting performance for multiple flights. The transparent design ensures discreet comfort while maintaining hygiene standards through easy cleaning between uses. Suitable for frequent flyers, sensitive ears, and family travel situations where reliable pressure regulation and moderate noise reduction are needed without complete sound isolation.
