Healthier Homes Start with Cleaner Air

Enjoy the confidence that comes from knowing you’re providing yourself & loved ones the air quality to thrive every day.

Cozy living room with plants and furniture, highlighting indoor air pollution compared to outdoor air.

Americans spend 90% of their time indoors—potentially breathing in harmful pollutants, including ultra-fine particles, mold spores, microplastics, and toxic gases like formaldehyde.

Chronic exposure to these contaminants may cause health issues starting with dry throat, coughing, and headaches and can lead to more serious conditions like heart disease, stroke, cognitive decline, and cancer.

Investing in a high-quality air purifier is essential for your health but not all air purifiers deliver the same level of filtration and performance.

Meet AirDoctor: Your Prescription for Clean Air

Why Many Air Purifiers Fall Short

Standard HEPA filters excel at larger particles but miss ultra-fine contaminants (dander, bacteria, & microplastics) that can enter your bloodstream.
Most purifiers lack premium carbon filters, allowing toxic volatile organic compounds (VOCs) from furniture, cooking, and cleaning to circulate freely.
A cheap air purifier can give you a false sense of security because the most dangerous threats can still slip through.

AirDoctor's got you covered. We test our filters on particles 100x smaller than the HEPA standard—so you breathe easy.

Air changes per hour (ACH) refers to how many times the air is changed with new, clean air in a given space within the span of an hour. A Harvard University Study cited by the CDC recommends at least 4 air changes per hour to effectively remove allergens like smoke, bacteria, viruses, dust, and pollen.

CADR, or Clean Air Delivery Rate, refers to your air purifier’s efficiency in removing these three contaminants over time: pollen, dust, and smoke. Higher CADR numbers indicate better air cleaning performance. The smoke CADR number is most stringent, reflecting the unit’s ability to eliminate the smallest and most dangerous particles from your indoor air.

Great question! Choosing the right air purifier will depend on the size of your room and the air circulations per hour. According to the Harvard University study, 4 air changes per hour are recommended for optimal purification. AirDoctor units are designed to meet this standard.
