When adding the minPoints option to the SuperClusterAlgorithm (minPoints: 1) clusters of size 1 are still showing up as markers.

const algorithm = new SuperClusterAlgorithm({
    maxZoom: 5,
    radius: 100,
    minPoints: 1,
});

let cluster = new MarkerClusterer({
    map: this.map,
    markers: [],
    algorithm: algorithm,
});
