Air Doctor vs Blue Air | What’s the Difference?

Air purifiers for homes have skyrocketed in popularity since the COVID-19 pandemic. The air inside your home can be five times more polluted than the air outside, and most people spend about 90% of their time indoors. Cooking fumes, gas/kerosene, building materials, paint, and other common domestic items and events have been shown to lead to a high concentration of toxic particles and contaminants in the home.

The difference between Air Doctor and Blue Air is the type of filters they use. Air Doctor uses the H13 UltraHEPA Filter, while Blue Air uses a proprietary SilentHEPA filter.

Choosing the best air purifier for your home is essential, especially if you have small children or immunocompromised people living with you. That’s why we’ve created this detailed guide where we explore the differences between Air Doctor and Blue Air! By the end of this guide, you’ll be confident about choosing the right air purifier for your home.

What’s the Difference Between Air Doctor and Blue Air?

The main difference between Air Doctor and Blue Air is the type of filter they use. Both use a 3-stage filtration system which includes a pre-filter, a carbon/VOC filter, and a HEPA filter.

Air Doctor uses the H13 UltraHEPA filter, which is capable of removing minuscule toxic particles and contaminants from the air. Blue Air uses its own type of HEPA filter called the SilentHEPA filter. This filter works to remove all the same contaminants from the air as the UltraHEPA filter, but it uses less energy and creates less sound.
