An air purifier draws in air through a fan, passes it through filters that trap particles and gases, then circulates the cleaned air back into your room. Depending on the filter types, a purifier can remove dust, pollen, pet dander, smoke, mold spores, bacteria, VOCs, and even some viruses.

Indoor air is constantly changing: every time you cook, your pet moves around, or you open a door, new particles enter the air. Turning your purifier off lets pollutants accumulate again. If running it all day isn't practical, aim for at least 12 hours daily and prioritize overnight use in your bedroom, where you spend 6–8 hours breathing while you sleep.

The core rules: keep it at least 6–12 inches from walls and furniture, avoid corners, and elevate it 3–5 feet off the ground if possible. Position it near the source of pollution — a litter box, cooking area, or a window — and between that source and where you spend most of your time. In bedrooms, place it within a few feet of where you sleep, but not blowing directly at your face.

To qualify, your doctor needs to prescribe one to treat a diagnosed medical condition (such as asthma, COPD, or chronic allergies), and you'll need a Letter of Medical Necessity to submit with your claim. If approved, replacement filters typically qualify too. Done right, you can save 20–40% on your purchase using pre-tax dollars.
