filterable

Filterable is an adjective describing something that can be filtered or subjected to filtration. In physical sciences, filterability refers to whether particles, solutions, or organisms can pass through a filter with a given pore size. Factors that influence filterability include particle size relative to pore size, shape, density, charge, and the properties of the filter medium such as pore structure and chemical affinity. Materials may be filterable with one filter but not with a finer or different type of filter.

In filtration technology, filterable materials are those that pass through a filter while other components are retained. Common benchmarks use pore sizes around 0.2 micrometers to separate bacteria from liquids; viruses are typically smaller and may pass through some filters, though recovery depends on the filter type and operating conditions.

Historical usage: In microbiology, the term filterable virus described infectious agents that passed through filters capable of trapping bacteria. This observation helped establish the concept of viral life forms and influenced the development of virology. Classic examples include the tobacco mosaic virus, which could pass through early filters that blocked bacteria.

In data and information contexts, filterable describes datasets, lists, or user interfaces that can be narrowed by filters. A filterable table or view allows users to display a subset of items by criteria such as date, category, or attribute. The term is commonly used in software design to denote interactive filtering capabilities.

Overall, the core idea of filterability is the compatibility between a filtrate and a filtration mechanism, which varies by domain and purpose.
