Mixed messages from government I'm afraid, can't remember seeing a BTP officer on buses who can enforce the fine.

IIRC, the transport police have no authority on buses, so it would be down to local police to enforce it

Possibly not effective as a mask but better than nothing and sports direct sell them for £3.

Wasn't there a study that showed a homemade mask with 2 layers of cotton were considerably more effective than a surgical mask?

The issue for me with wearing any face covering is it restricts the airflow too much, and when it's quite humid like it is now, I can barely breathe properly even without covering my face.

For me, it's the breathing out that causes the most issues with a face covering, usually that wouldn't be a problem because I can use the vented dust masks, but the reason we have to use face coverings is to stop the things on the way out rather than on the way in, which is what vented masks are designed for, so that would defeat the purpose.
