The wind instrument double-layer bell cover for 18 to 19-inch bell sizes fits securely over the bell opening of your instrument to help reduce the spread of aerosols during use. The GBELLCVR1819BK comes equipped with a removable MERV-13 filter and is designed to meet the recommendations set forth by the Performing Arts Aerosol Study commissioned by the National Federation of State High School Association (NFHS). The cover features an elastic closure and cord lock that allows you to tighten it over your bell cover for a snug fit and does not cause any backpressure or noticeable acoustic loss during performances. To clean, simply hand wash and let air dry (do not machine wash). The GBELLCVR1819BK will fit tubas and similar-size Instruments with larger bells, but to guarantee best fit, be sure to measure the bell diameter of your instrument prior to ordering.
