Abstract
Embodiments are directed to microfluidic refill cartridges and methods of assembling same. The microfluidic refill cartridges include a microfluidic delivery member that includes a filter for filtering fluid passed therethrough. The filter may be configured to block particles above a threshold size to prevent blockage in the nozzles. For instance, particles having a dimension that is larger than the diameter of the nozzles can block or reduce fluid flow through the nozzle.
