The 11 Best Air Purifiers

Even if you keep your home super clean, the air can contain a lot of particles — and these particles are often especially irritating for people with allergies. Luckily, the best air purifiers help to minimize common air pollutants like dirt, dust, pet dander, and smoke. And when the air is cleaner, your home will feel like a way more comfortable place.

Since air pollutants aren't visible to the naked eye, it can be easy to forget that they're even there. But if you suffer from from allergies or a respiratory condition, feeling more irritated when you're in your house is a pretty clear sign that something's amiss with your home's air. HEPA air purifies are widely recognized as the best at reducing airborne allergens, which makes these a great option for people with allergies or other conditions. And even if you don't suffer from allergies, a great air purifier can simply make your home smell fresher by pulling odors (like cat litter and musty furniture) out of the air.

If you've been hesitating to try an air purifier because of the cost, keep in mind that these appliances fall in a wide range of price points from very affordable to ultra-luxe. These 11 air purifiers are some of the most highly-rated out there — and some costs less than your monthly coffee budget.
