thanks to Due to the COVID pandemic and the never-ending wildfires, air purifiers have become an essential home appliance for overall health. Almost every building releases a lot of particulate matter, volatile organic compounds and volatile chemicals. Not to mention the gases emitted from indoor plastics, furniture and paint. It’s important to make sure the air you’re breathing is clean – from preventing coughs and allergy symptoms to helping us wake up with clearer sinuses and less hoarse throats – air purifiers can make all the difference. AirDoctor makes countless efficient air purifiers for every type of home, and we have AirDoctor promo codes and deals to help you save big on clean air.

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 overlooked) toxins in addition to everyday things like smoke, paint, and pet dander. We know the importance of clean air, and that’s why we’ve set up a handy guide on how to buy an air purifier, covering important, but often overlooked points, such as how to fit an air purifier in your room and how to choose the air purifier best suited to your home’s needs. We’ve also spent months testing air purifiers, and have selected the best air purifiers for your home, including our picks for small or large rooms and air purifiers with built-in fans or heaters.
We thought the AirDoctor Smart 5500i is the best purifier for PM 2.5 and gases because it captures fine particles with its HEPA filter and dual action/carbon volatile organic compound trap filter, while exchanging air four times an hour in a 1,000-square-foot space. The purifier also has a convenient alert that lets you know when it’s time to change the filter. There are lots of different AirDoctor options for different sized rooms, so make sure you read our guides and take measurements of your home before purchasing to make sure you have the best AirDoctor air purifier for your space.
