@DaasYochid .
Sorry but you can’t compare TAG to yeshivas and shuls. Its a poor analogy for many reasons. For starters, whether you like it or not people aren’t yet convinced that you need filters. And by charging them you won’t get them to do it. Secondly, in fact most shuls and yeshivas indeed have a system where people who totally ca’t afford it get off easy or a discounted price. Why can’t TAG offer that? Its not like food because selling food isn’t charity. You are charity . Selloing food isn’t inhernetly a holy thing promoting judaism. And in fact there are a ton of frum organztaions offering free or hevaily discountede food to those that can’t afford it. Again TAG should do the same. Bottom line, yes many relaize that its a given like the pirce of a hashgacha that we all pay for. But there are more than you think who don’t see filters as a must yet. They see it as an extra thng that’s nice to do if easy. You may disagree with that mindset. But that’s how they see it. And if you want them to “eat kosher” via filters and you are a tzadka stop charging. You also collect money for this mosad. What else should it be for other than free or cheaper filters?
