The 6 Best Cheap Air Purifiers

Bustle/Amazon

When it comes to improving the quality of a living space, an air purifier is one of the most affordable and instantly-effective options. And while searching for the best cheap air purifiers, there are a few different factors to consider.

The best air purifiers come in a range of sizes and degrees of power, so it’s important to first consider the square footage of the room the air purifier will be used in. Oftentimes a purifier will be designed with a maximum space it can handle, so you'll want to ensure the one you choose has the level of power you need to effectively clean your entire room.

As you decide which air purifier is right for you, you'll also want to consider how the purifier works. While many popular air purifiers use HEPA ("high-efficiency particulate air") filters, they can be costly to replace. Other air purifiers, including a few on this list, use both a HEPA filter and an Activated Carbon Filter. If you are particularly focused on odor control, you'll want to look look for an air purifier with a combination Activated Carbon and HEPA filter for the most effectiveness.

Whether you're looking for a small purifier you can take with you anywhere or a heavy-duty air purifier for a large space, you'll find great options on this list. Here are six of the best cheap air purifiers to help maintain a clean and healthy living space on a budget.
