A simple one-cup stainless steel tea strainer

If you’re drinking a nice pot of plastic-free tea, then it pays to use plastic-free tea making tools!  Use with energy-saving kettles.

This in-cup tea strainer is made from stainless steel, like an upgraded  version of the hand-held one your mother likely had. Fitting inside most mugs, just add loose tea, put over a mug and leave to infuse. For fine tea (like spearmint or peppermint) wet the strainer before you add the tea.

Avoid caffeine for pregnancy/nursing. 

Swishing coffee grounds into sinks could clog drains, so use a SinkShield. Unless you have a food waste bin, just bin tea leaves (and coffee grounds) to avoid caffeine harming compost creatures. 

Tea Lab paper filters

Tea Lab Paper Filters are filled with loose tea. Then just pour over the water, and use the drawstring to brew and then dispose of the tea bag, to safely return to the earth. Each box contains 50 bags.

This brand also sells organic tea in glass jars, with profits helping to rescue orphaned elephants and rhinos. The letterbox mailer teas are sent in glass test tubes with cork lids, including eco-fillable tea bags.
