Etymology
濾 combines 氵 (water) with 慮, which likely contributes the sound and the idea of careful consideration, suggesting the careful separation of water from impurities.
Meaning mnemonic
Water 氵 passes through the thoughtful, careful structure of 慮, like a mind sifting through thoughts. Imagine pouring water through a fine mesh that only lets the purest drops through.
Reading mnemonic
For ロ, picture a low, slow pour through a filter: low -> ロ, and the water drips down carefully.
