Shop-Vac 90115 Dacron Cloth Filter Replacements for Most Shop-Vac Wet/Dry Vacuum Cleaners 5 Gallon and Above, 9011500, 2 Pack

The Shop-Vac 90115 Dacron Cloth Filter Replacements come in a pack of two and can be used with most Shop-Vac WetDry Vacuum Cleaners with a capacity of 5 gallons and above. However, the instructions on how to use these filters are unclear, and it seems they are meant to be used in place of the original paper filter, not over it as a pre-filter, which may have caused confusion for some customers. The mesh size of the dacron material in this filter is not specified, but it is marked as "General Filtration," not "Fine Filtration." Some customers have reported that it does let ash particles through, but it serves as an additional barrier for filtration. The filters are easier to install than paper filters and require less storage space. However, the filters seem to be hit or miss in terms of their quality. Some customers have reported that the cloth filter rips at the seam or doesn't fit over the original filter properly, while others have found them to be a great alternative to HEPA filters. One customer has reported that the filter caused sawdust to get into the motor and had to be removed. Overall, these cloth filters are a budget-friendly alternative to paper filters or HEPA filters but may not work well with all Shop-Vac models. Customers should check the instructions carefully before use and monitor the quality and effectiveness of the filters.
