3M Peltor Hygiene Kit for Optime 105 Muffs

The 3M Peltor hygiene kit for Optime 105 ear muffs replaces the ear cushions and foam inserts. Fresh cushions restore the seal that hearing protection depends on, which wears away fast with sweat, sun and sawdust.

Why the seal matters

Optime 105 muffs are high-attenuation muffs, but they only protect at their rating if the cushions seal. Hard, cracked or flattened cushions let saw and chipper noise leak in. Swapping them out is cheap compared with the hearing loss that leaks cause over years of work.

Plan on replacing the cushions at least once or twice a year with daily use, or sooner if they harden or split.

Sweat, sun and sawdust all speed up cushion wear, and hot summers can harden them faster than you might think.

The kit is a quick job to fit at the start of a season, and it makes an old set of muffs feel like new again.

How to fit them

Pull the old cushions off the cups, remove the old foam, insert the new foam and press the new cushions on until they snap into place all around. Check that they sit flat and the cups close properly.

Clean cushions with mild soap and water only. More options are in our hearing protection section.

Keep a spare set in the truck so a split cushion never means working without hearing protection.

Store the muffs out of direct sun and avoid crushing the cushions in the truck, which keeps them sealing longer.
