What is suggested as a cost-effective alternative to disposable pyramid bags for retaining flavor profile?

Purchasing the same high-quality tea in loose form and using a reusable infuser.

If direct replacements for pyramid bags become difficult to source or excessively expensive, the recommended adaptation strategy involves moving toward loose leaf tea, provided the consumer enjoys the quality offered by specialty vendors. Many specialty vendors sell the same high-quality tea both bagged and loose. By purchasing the loose leaf and investing in a large, reusable infuser or metal tea ball, the consumer sacrifices the absolute convenience of a disposable sachet but gains an infusion that is often even superior while proving more cost-effective over the long term. This method successfully preserves the desired flavor profile linked to the high-quality leaf previously contained in the pyramid structure.
