All the information you need is on the website of Pall, a world leader in filtration:

Specifically:
Is there a danger to maintenance personnel by removing used cabin air filters?
There is no more risk involved in replacing a cabin air filter than carrying out general maintenance on
any aircraft part that has been in service for a number of years. Maintenance staff should wear the
same personal protective equipment as for other aircraft maintenance tasks which require protection
against dust, and per the local regulations.
The used HEPA filter should be placed and sealed in a plastic bag. A specific biohazard bag is not
required for disposal of the HEPA filter in most juristictions.
