About us

Our history

Carlson Filtration was established in 1923 by John Cecil Carlson (born in Sweden in 1897) and has been based at Butts Mill, Barnoldswick since 1956

Butts Mill was originally built in 1846 as a steam-powered cotton mill but was converted to a weaving mill in 1887. Part of the original mill was demolished in the early 1900's with the remainder modified to a single floor building accommodating in excess of 1900 looms by 1915. The site has undergone significant modernisation since then as the aerial photograph shows with only a small part of the original "saw tooth" roof with north facing glazed lights remaining.

The infrastructure of the mill has been improved considerably; significant investment has also taken place on the machine itself and this investment continues.

Carlson has had several owners in the intervening years but has been a part of the Filtrox Group since 1988. In 1999 Carlson applied to the US Food and Drug Administration for - and was granted - a Type 1 Drug Master File Number - DMF14255. This is still in place meaning that our products can be used with confidence within the pharmaceutical industry. It is more generally indicative of the high quality standards of our products.

Company Philosophy

We have 4 key areas of responsibility:

1.

To the Health and Safety of our employees.
To achieve this we ensure that they are all fully trained to undertake their responsibilities (we are accredited to IIP Standard), that we operate within all relevant Health and Safety legislation and by actively developing a health and safety culture within the company.

2.

To the environment.
Our operations conform to all relevant legislation and, by continuously investing in modern operating methods and process control systems, we ensure that the impact on the environment and our neighbours in the local Barnoldswick community is minimised.

3.

To our customers.
We work very hard to fully meet or exceed the requirements and expectations of our customers in terms of quality, delivery, product performance and cost effectiveness. Operating in full compliance with ISO 9001:2008 is just one means by which we achieve this aim.

4.

To our owners.
If we want to continue until and beyond our centenary we have to be both profitable and effective. A key method of ensuring this is to meet the other 3 key areas of responsibility.
