About Thor Filtration

Thor Air Filters are hand assembled in a UK factory in Hampshire. Only high quality components are used in their manufacture.
The motors are Swiss made to a very high standard and are also very reliable. Thermally protected and therefore most important to woodworkers they are spark proof, consequently there is  less chance of dust combustion. Ingress protected to IP44 standard.

The range was reintroduced by Thor following the wind up of Microclene. This was due to popular demand. Originally they were designed and manufactured in response to the high number of cancer cases caused by timber dust inhalation mentioned in the national press. In the first two years Microclene filters were given several awards, “Health & Safety product of the Year” “Services to the Woodwork Industry Award” and others.

Timber Dust is the largest market,  but some other markets utilise them including : racehorse stables, hospitals, schools, colleges, universities, metal grinding, indoor aviaries, dental labs, printing works.

For years people have thought that only the exotic timbers were a danger to health, then the European timbers were tested and found to be just as dangerous, causing all sorts of health problems, including nasal cancer, asthma etc.
