Fantom Thunder was a very good carpet cleaning vacuum, BUT, once James Dyson invented MEMA filters, he brought them to Fantom since they were allowed to use his patents. Fantom paid Mr. Dyson a licensing fee to use his patents. Fantom was so greedy they did not want to use washable filters (since they were in the BUSINESS of selling HEPA filters). James did not renew his agreement with Fantom, and out of business they went. Plain greed. Pure and simple. Fantom built their machines without pre-motor filters so the dust would go directly to the HEPA filter, which cost $75.
