Cartridge respirators let in the same amount of oxygen as you would get with
normal breathing, so unless you are working in an oxygen depleted
environment, the mask shouldn't make a difference. Some people experience a
sensation as if they are suffocating in devices that cover their nose and
mouth, even though CO2 is exhaled through a valve in the bottom so it
doesn't build up in the mask. The masks do take slightly more diaphram
exertion to inhale and exhale. Facial sweat and condensation buildup can
also be disconcerting, but this is probably true for full face masks as
well. Is it the extra effort required with cartridge respirators that causes
you problems, or is it a sensation of suffocation? The former probably
requires assisted air feed; the latter can be overcome by getting used to
it.

North, 3M, Willson, etc all make quality respirators. 3M also makes a
variety of portable battery powered respirators. The important thing is to
select the correct filter for the contaminant. I presume that dry gourd
processing involves fine dust and maybe mold spores?
