# `whereNotIn()`

The whereNotIn method filters the collection by a given key / value not contained within the given array:

```js
const collection = collect([
  { product: 'Desk', price: 200 },
  { product: 'Chair', price: 100 },
  { product: 'Bookcase', price: 150 },
  { product: 'Door', price: 100 },
]);

const filtered = collection.whereNotIn('price', [150, 200]);

filtered.all();

// [
//   { product: 'Chair', price: 100 },
//   { product: 'Door', price: 100 },
// ]
```

> When working with nested objects `whereNotIn()` method allows dot notated keys. E.g. `whereNotIn('product .categories', ['office-supplies', 'furniture'])`
