Filter replacement is part of any Louisville vacuum repair and maintenance service. HEPA filters are known to operate more efficiently the more dust they capture, but even they don't last forever. Experts recommend replacing them every two years. Distributors like Leonard Brush and Chemical offer repair services on top of their wide array of cleaner accessories and supplies. Cleaning, in general, won't be of much help if the cleaning equipment itself isn't clean. This also applies for most Louisville janitorial supplies.
