Frequently Asked Questions

When will I receive my AD4000?

The Air Doctor 4000 is expected to ship this Summer. This exclusive 50% discount is only available during this special pre-order period. You will receive real-time updates of the manufacturing and shipping process as they occur.

Why are air changes per hour (ACH) important when shopping for an air purifier?

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.

What is CADR, and why’s it important?

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.

How often do I need to change the filters?

Replace your AD4000 filters every 6 months.

Can I cancel my order and get a refund?

You may cancel and get a full refund any time before the product is shipped. However, once you receive the product, you will be subject to our 30-day return policy.

If for any reason you're not completely satisfied with your AirDoctor, simply reach out to our customer service team at 1-800-221-2515, and we'll gladly issue you a full refund, minus shipping and processing fees.
