How to download Image collection from google earth engine?

Question

I want to save each image of this collection into my drive.

var filtered_Image=ee.ImageCollection('LANDSAT/LC8_L1T_TOA')
.filter(ee.Filter.eq('WRS_PATH', 138))
.filter(ee.Filter.eq('WRS_ROW', 45))
.filterMetadata('CLOUD_COVER','less_than',20)
.filterDate('2017-01-01', '2017-06-31')
.select(['B2', 'B3', 'B4']);

Try this

choose your geometry/point of interest from imports.

var batch = require('users/fitoprincipe/geetools:batch');


var filtered_Image=ee.ImageCollection('LANDSAT/LC8_L1T_TOA')
                     .filterBounds(POI)
                     .filter(ee.Filter.eq('WRS_PATH', 138))
                     .filter(ee.Filter.eq('WRS_ROW', 45))
                     .filterMetadata('CLOUD_COVER','less_than',20)
                     .filterDate('2017-01-01', '2019-12-31')
                     .select(['B2', 'B3', 'B4']);

Map.setCenter(88, 21, 7);

var vizParams = {
  bands: ['B2', 'B3', 'B4'],
  min: 0,
  max: 0.5,
  gamma: [0.95, 1.1, 1]
};

Map.addLayer (filtered_Image.first(),  vizParams, 'false color composite')


batch.Download.ImageCollection.toDrive(filtered_Image, 'Landsat8', {
  name: 'filtered_Image_{system:index}',
  type: 'float',
  scale: 30,
  region: POI
});
