A pool cover includes, in a preferred embodiment, an array of openings through an otherwise impervious pool cover sheet. A pair of filter units overlies the openings and allows only filtered water from the pool cover to drain into an underlying pool of water. A first (bottom) of the filter units is fixedly attached to the impervious sheet and includes a screen member tautly stretched across the array of openings for sharing stress in the sheet in the vicinity of the openings, and also includes a micromesh filter layer overlying the screen member. The second of the filter units is removably attachable to the first unit, as by VELCRO fastenings, and includes a lower micromesh filter layer, for directly overlying the micromesh filter layer of the first unit, and a macromesh filter layer directly overlying the micromesh filter layer. In use, debris is stored substantially only on and within the second (top) unit, and the first (bottom) unit functions for trapping debris only while the second unit is removed for cleaning.
