Have MULTI FIT Foam Sleeves on hand whenever the job calls for it with this 3-count value pack - buy more and save more. The MULTI FIT Foam Filter Sleeve is designed to fit most Vacmaster and Shop-Vac branded wet/dry vacuums. The high quality MULTI FIT foam filter sleeve is easy to use and helps with wet pickups while protecting wet debris from entering the motor. This reusable foam sleeve can cleanup wet messes and waterborne debris and should not be used for a standard dry dust filter. A shop vacuum filter increases the optimal vacuum performance and prolongs the life of the vac by protecting the motor from harmful particles that could effect the motor. Plus, this filter is washable and, when fully dry, reusable. Installation and removal is simple so the job can get done quickly and efficiently. To install, slide the MULTI FIT foam filter over the shop vac filter cage assembly - no tools required. Also, a 6-count value pack size is available to accommodate a variety of job needs.
