Although paper tea bags are convenient, there are three important reasons to limit their use (ideally to zero!):

1. Plastic in paper tea bags
   Many paper tea bags contain polypropylene (plastic) to keep the bag sturdy and heat-resistant. When exposed to hot water, microplastics can end up in your tea.

2. Chemical treatment
   Paper tea bags are often reinforced with epichlorohydrin to prevent tearing. When in contact with hot water, this substance can hydrolyze into 3-monochloropropane-1,2-diol, a known carcinogenic compound.

3. Chlorine bleaching
   Many tea bags are bleached with chlorine, which can leave residues in the water when brewing tea.

For a pure and safe tea experience, choose loose whole tea leaves and a glass or stainless steel tea infuser.
