The opposite of "more filtered" is "less filtered." When something is less filtered, it means that it has not been screened or processed as thoroughly. This can refer to various things, such as untreated water, unrefined oil, or raw data. The degree of filtration can affect the quality, purity, and safety of a product or information. For instance, unfiltered water can contain harmful bacteria and pollutants, while unfiltered data can be misleading or unreliable. Therefore, it is important to balance the level of filtration with the purpose and standards of the desired output. In some cases, less filtration can offer a more natural or authentic experience, while in others, more filtration can enhance the value and usefulness of the result.
