Probably not this issue. Probably shipping issues.
Oxygen concentrator zeolite is a lithium compound adhered to stryofoam beads (since only the surface interactions are of interest).
They use different zeolites for different processes. For example the zeolite that adsorbs fluoride ion is activated alumina. I cannot imagine they'd put "dirt", even "white dirt" in a detergent.
The only reference when searching for an MSDS for OdorZOut I found called it chlorine dioxide... which is a STRONG bleach. Definitely not a "zeolite". But probably not the right stuff.
Website and other anti-chemical tin foil hat sites describe it as a
natural zeolite powder (and discontinued). The MSDS says complex mixture including sodium bicarbonate, cellulose, fragrance and IPA unlikely to
do harm.

Perhaps not quite as benign as they claimed.
However, it is lacking the Z here. Looks to me like an expensive way for
the chemophobics to buy crushed rock mixed with 1% bicarbonate of soda.
I'm suspicious of "brands" that don't have a manufacturer's name on.

If you don't mind the bleaching effect chlorine dioxide is most easily
produced in situ with hydrochloric acid (aka brick acid) and hydrogen
peroxide. It is a powerful oxidising agent. Do not breathe the fumes.
Quite a dangerous combination at etch strength that should never be
stored and used immediately after mixing in dilute solution. Never
really considered it as a cleaning oxidiser as such. I suspect on
laundry it may have deleterious effects on both dyes and fabrics.
One of the cleaner copper etch chemistries but don't breathe the fumes.
Much less messy to use than ferric chloride.
Permanganates and perborates are other powerful oxidisers that various
washing powders have been known to use. ISTR there was a bit of a
scandal when someone broke the permanganate embargo and it destroyed
cotton undergarments in no time flat. 1930's technology but it occurred
a couple of decades ago if memory serves. US NBS on bleaching 1930's.
