Default Musty AC smell

My 97 Camry a/c has a musty smell when starting and it continues all
the time. I have tried
Ozium spray in the vents but to no avail..Any suggestions will be
appreciated.

The problem is particularly bad in that generation of Camry. Later ones
have fungicide epoxy coated on the evaporator.

But if the spray didn't work then it may be your cam/crank seal and/or
water pump leaking. Do you have this smell when you open the door first
thing in the morning? I did and I've managed to rid what I thought was
the foul smell after replacing the said parts in a timing belt job,
realizing afterward it's either the oem seals or the Aisin pump.
Needless to say, I've always liked Fel-pro seals and NAPA Airtex pumps.

If it's fungus, when you spray the ventilation system you should also
include the evaporator and housing. Haynes repair manual has some
description of it. That where the moisture is and fungus loves it.

Mold or fungus can be easily killed with spraying household bleach , but
you need to find where it is growing such as on the Ac coil, Air
fresheners just hide smells. A partialy clogged condensate drain will
hold water making mold grow faster.

=====================
Once read someone had success with eliminating odor from mold or fungus
growth in the ductwork by running the heater controls at full heat for
8-10 minutes.

You can minimize recurrence by turning off A/C and leaving fan on, then
driving several blocks before shutting off the engine.
