What does the AirDoctor purifier do?

As mentioned above, air purifiers can help clean the air in your home, especially against some lesser-known (or noticeable) toxins as well as everyday things like smoke, paint, and pet dander. We know the importance of clean air, which is why we’ve put together a handy guide on how to buy an air purifier, including important, but often overlooked points, like how to fit your room with an air purifier and how to choose the one that best suits your home’s needs. We’ve also spent months testing air purifiers, and we’ve rounded up the best air purifiers for your home, including our picks for small or large rooms, and those with built-in fans or heaters.

We thought the AirDoctor Smart 5500i was the best purifier for PM 2.5 and gases because it captures fine particles using HEPA filters and gases using dual-action VOC/carbon trap filters, all while exchanging air four times per hour in a 1,000 square foot space. The purifier also has a handy alert to let you know when it’s time to change the filter. There are lots of different AirDoctor options for different sized rooms, so be sure to read our guides and measure your home before purchasing to ensure you get the best AirDoctor air purifier for your space.
