Air Purifiers & Dehumidifiers

They solve different problems. An air purifier draws air through filters to capture dust, pollen, smoke and other airborne particles. A dehumidifier removes moisture from the air, which helps with damp walls, condensation and musty smells. If your apartment feels dusty or stuffy, a purifier suits you, and if you see mold or condensation in humid months, a dehumidifier is the better fit.

Check the recommended room size or the clean air delivery rate (CADR) listed by the manufacturer. CADR shows how much filtered air the purifier delivers, and a higher figure suits a larger room. As a rough guide, choose a model rated for a room at least as large as yours, or a little larger if you want it to clean well on lower, quieter fan speeds.

It depends on the model, how many hours a day it runs and how dusty your home is. Many purifiers have a filter indicator that tells you when a change is due, and the manual gives a guide interval. Some models also have a washable pre-filter that you can rinse or vacuum to catch larger dust and hair, which helps the main filter last longer.

Many people aim for indoor humidity of roughly 40 to 60 percent, which feels comfortable and helps discourage mold and dust mites. Coastal apartments can feel very damp in summer and during rainy winter weeks, so a dehumidifier with an adjustable humidity setting is useful. Empty the water tank regularly, or use a drain hose if your model supports one.
