Having trouble finding filter that fits this vacuum. I see in the owner's manual the part # 551301101, but that number doesn't help me at Menards or Amazon. I have tried twice to buy filters that state they fit Masterforce 5-16 gallon vac's but those filters are too large. How/where can I get replacement filters for this vac?
