Air purifiers could not be more relevant than right now when we’re all getting ready to hunker down inside until the spring. If you’ve been interested in getting an air purifier, but don’t want to spend $400 to $700 on a Dyson, you don’t have to: There are plenty of air purifiers for under $150, and some even clocking in under that $50 price-point.

The allure of an air purifier is that it can capture and filter microscopic allergens in the air. Indoor air pollutants can be significantly worse than outdoor pollutants, so an air purifier is ideal in the home, especially for those who have asthma-like symptoms and allergies. Some of them are even designed with a HEPA filter to trap particles as small as 0.3 microns from air passing through.
