An inkjet printhead includes a supporting wafer substrate; an array of drop ejection apparatuses formed in a first side of the supporting wafer substrate, the array of drop ejection apparatuses configured as pairs of rows of drop ejection apparatuses, each drop ejection apparatus including a chamber with a nozzle, and an actuator extending into the nozzle; and a common ink channel extending between each pair of rows of drop ejection apparatuses. Each chamber has a sidewall adjacent to the common ink channel, the side wall provided with a grill portion for facilitating an in-flow of ink from the common ink channel into the chamber, the grill portion adapted to further filter the ink flowing therethrough.
