Top Ten Air Purifiers for Small Spaces

Shopping Guide

Pin it button big

If you're thinking of buying an air purifier, we suggest you invest first in a bedroom model. It's the space where you spend the most time, and an air purifier will make the biggest impact there. Air cleaners also tend to be less expensive when they're designed for smaller spaces.

DO: Look for a model with a HEPA filter and a high Clean Air Delivery Rate (CADR) — the number indicates the amount of air moving through the filter by area. Make sure the design has a sturdy, solid casing, preferably made from metal or hard plastic.

DON'T: Non-HEPA filters and models that release ozone into the air generally aren't reliable. Avoid buying a model with vents that direct clean air downward, which will stir up dust and allergens from the floor.
