Seal checks for disposable respirators: A seal check can be done by placing both hands over the respirator itself, or by using a device provided by the manufacturer.

Respirator mask

In general, adjust the straps so that the respirator fits tightly but does not dig into your face or leave red marks on your skin. The respirator should feel snug but comfortable. Straps should be placed under a hard hat or hood. Position the straps correctly – one strap should go above the ears and over the crown of your head, and the other below the ears and around the neck. If the respirator has adjustable straps, tighten or loosen them without removing the respirator.

Ventilator

Negative pressure seal check: Negative-pressure checks can be done on air-purifying respirators and other respirators with a tight fitting facepiece.

In order to get professionally made ear impressions, you must schedule an appointment with an audiologist. View our list of Gold Circle audiologists, or contact us for a referral.

Our ER Series Musician Earplugs were developed specifically as hearing protection for musicians and production personnel who are exposed to unsafe sound levels but still require high fidelity sound. Unlike the muffled sound of over-the-counter foam and unfiltered earplugs, the ER Series is made with music in mind, making them perfect for concert-goers as well, delivering balanced sound reduction with very little disruption of frequency response. Definition of mid and high frequencies can be heard clearly for a safer, yet truly musical listening experience.

Elastomeric facepieces are made of silicone, thermoplastic, or rubber material. One or more filters or cartridges are attached to the facepiece.

Each pair includes one pair of attenuating filters. Choose from 9dB, 15dB, or 25dB attenuation. Please contact Sensaphonics or your audiologist to learn the best choice for your listening situation. Additional filters can be purchased separately.

Always follow the directions provided by the manufacture and your employer. These instructions describe how to put on a reusable elastomeric half-facepiece. Full face respirators would follow a similar process.

PPE

In general, hold the respirator in your hand with the nosepiece near your fingertips. Place the mask over your nose and mouth, and hold with one hand. Using your other hand, pull the top strap over your ears. Pull the bottom strap behind your head and below your ears. If there is a clip, clip it behind your neck. If there is a metal nosepiece, mould it around your nose to create a proper seal.

The fit of your respirator should be evaluated periodically. For example, if you have lost or gained weight or have been fitted with new dentures, the shape of your face may have changed. Therefore, the fit and seal of your respirator may change.

Positive pressure seal check: Positive-pressure seal checks can be done with respirators equipped with tight-fitting facepieces that have both inhalation and exhalation valves.

When fitting a new respirator, try on several brands and sizes when possible. Different brands will fit slightly differently on your face. You may be asked to talk, move your head/face, or make other movements to determine if the respirator is a good choice for you. You may also be asked to remove facial hair where it interferes with the seal between the respirator and skin.

Filtering facepiece respirators are those respirators in which the entire facepiece acts as the filter. These respirators usually cover half of your face, and are sometimes called "disposable" respirators.

To ensure the maximum protection and quality, our in-ear monitors are custom fit to your ear. After your order is placed, please follow these steps to ensure successful delivery of your custom-fit IEM.

Each time and every time a respirator is worn, you must check that the respirator is sealing properly to the face. Not all respirators will allow the wearer to temporarily block the inlet openings or valves, but these checks should be done whenever possible. Do not wear a respirator that does not seal properly.
