NOTES:
1. Do you require a filter for particulates? If so, this will be selected during the the buying process for cabinets supplied by Bigneat and Erlab - this is because the "particulate" or "HEPA" filter is supplied in "combination".

2. Carbon Filters Direct is currently unable to provide particulate filters for other manufacturers of cabinets without more detailed specifications from you about your cabinet and sizes of the HEPA filter you currently have installed. Pleased note that 
CFD would be pleased to advise you of a HEPA filter to suit your application and we welcome you getting in touch with us.
