A small purifier suits a bedroom, nursery or home office up to about 230 square feet. Noise matters most here: you’ll likely run it overnight, and a purifier only reaches its rated CADR at top speed. If you want it near silent while you sleep, a model from the medium list running on a low speed often cleans as well as a small one on high, and more quietly.
