Combined HEPA vs Carbon filter - Solder Fume
Combined HEPA vs Carbon filter - Solder Fume
(OP)
Hi
Im working on a system to control the contaminants from blow torch soldering.
I've narrowed it down to installing a mobile extraction unit with a flex arm to hang over the process.
The capture velocity and volume airflow is adequate for the process.
The question I have is to differentiate between choosing a unit which has a combined HEPA/Gas filter or a unit with a Carbon filter.
I understand the combined filter as having a much higher efficiency but the price of the unit is nearly three times the price.
I'd like to know what the main differences are between the two filter systems, the pros and cons if possible and any reading material that may help.
Any help is appreciated.
Thanks in advance

If you have to have a filter, put a medium efficiency filter ahead of the HEPA (to prolong its life), and then the Carbon filter. Carbon filters are not meant to capture particles, but take out odors.
Both HEPA and Carbon are large, expensive and have a large dp (1" when clean).
