This is wise advise. Even a non cartridge mask will help. Also, consider using a fan blowing in fresh air.I’ve never experienced nosebleeds or respiratory issues with either product, but prolonged exposure (like over the course of a bottling session) to star San does dry my skin, nothing a little lotion can’t remedy.
It could be you’re just more sensitive to them. You can get dual cartridge respirator at harbor freight for $17. Some long cuff cleaning gloves wouldn’t be a bad idea either.
