Instrument Bell Covers from FJM

In response to numerous requests, we are pleased to offer these products for schools and organizations looking to equip their members with a cohesive solution for larger gatherings and ensemble rehearsals. 

Based on a recent study investigating airflow and particle dispersion from instrumentalists and vocalists, the preliminary results included the statement, "Masks, nylon bell coverings all reduced particle concentrations."

In addition to this, the study found that, "Concentrations were relatively higher for instruments that had straight

shapes from mouthpiece to bell."

We are pleased to offer this solution for 'belled' instruments of all sizes made from the same material as our gaiter masks!

Our standard bell covers come in one-ply. If you would like to reinforce the bell covers with 2 layers, we have found that it is simple and cost-effective to put one cover on top of the other. 

Another option for reinforcement is to place a cut-to-size piece of Merv 13 filtration material over the bell in addition to the cover(s). Rolls of Merv 13 can be found at most home improvement stores or on Amazon here.

These coverings are intended to provide a barrier for airborne particles that escape out of the instrument bell when playing. 

We recommend washing before first use. 

Please remember that the use of bell covers is not intended to replace other recommended measures to stop the community spread of COVID-19, such as social distancing, washing your hands and refraining from touching your face. Follow the latest advice of the CDC and your own health care professionals as to how best to keep yourself safe.
