Blanket Filters
Blanket Filters is an Exploration Age Market technology for Asian civilizations and Ethiopians. It improves Coin gathering from mines and Mountain Monasteries by 5%, and opens the follow-up mining upgrade, Flume and Ditching.

Effect
Research costs 40 Food and 40 Wood and takes 15 seconds. The bonus applies to the listed Coin sources, not unrelated resource gathering. Flume and Ditching becomes available afterward, so Blanket Filters can serve as the first step in a Market research chain.
Research condition
Asian civilizations; Exploration Age; Market; 40 Food · 40 Wood; 15 seconds. Ethiopians require the Indian alliance and pay 70 Influence.
Research decision
Research when enough Villagers are working at mines or a Mountain Monastery and the economy can spare the cost. Its immediate return is small if no workers use those sources. Consider it early enough for the 5% increase to accumulate and include the follow-up cost if planning to reach Flume and Ditching.
Mining efficiency and the next upgrade
Blanket Filters is a modest Coin-gathering improvement that can be valuable over a long mining period. Because it also unlocks Flume and Ditching, its strategic value may include access to the next technology. Do not assume the 5% applies to all Coin income: it is limited to mines and Mountain Monasteries. Secure the workers and resource deposits so the gathering improvement remains active after the research finishes.
