Frequently Asked Questions

I need help with my mask fit or have questions about my CPAP supplies. Who can I call?

While our sleep experts are happy to help answer your questions over the phone, some matters may be best resolved by a visit with your primary care physician.

How do I reset my modem?

CPAP machine modems run on cellular signal and sometimes need to be reset for data to send correctly. If we contact you asking you to reset your modem, locate the small black button on the back of your CPAP machine near the antenna and push and hold for 5 seconds, then release.

I lost weight and don’t think I need a CPAP anymore. Can you retest me?

Yes. Many people find that losing weight will significantly reduce their AHI. Contact Aeroflow to schedule another sleep study and find out if your need for a CPAP has reduced.

If I haven’t met my insurance deductible yet, will I have to pay out of pocket?

For patients with high-deductibles, we offer a self-pay service through You can order any supplies through this website until you reach your deductible, and then Aeroflow can help you work with your insurance company until your deductible resets.

I don’t have insurance. How do I get CPAP supplies?

For drivers without insurance and whose company’s do not offer assistance for treatment, we have set up a website called that provides the minimum-allowed manufacturer pricing on all CPAP supplies and accessories.

How often should I replace my CPAP Supplies?

Every 6 months: Replace headgear, chinstraps, non-disposable filters and humidifier water chambers.
Every 3 months: Replace masks and tubing.
Twice a month: Replace cushions, pillows and disposable filters.

Why does my BMI and neck size matter?

While a variety of factors can contribute to sleep apnea, several studies have found that individuals with a BMI of 35 or higher and a neck size of 17 or greater (16 or greater for women), are at a significantly increased risk of airway obstruction due to increased weight on the throat.

What does “compliance” mean and why is it important?

The DOT requires a minimum CPAP compliance rate of at least 4 hours a day, 5 days a week, which equates to 70% of sleeping time. Aeroflow helps monitor your CPAP usage and reports the data to your employer. Drivers who are diagnosed with sleep apnea and are not compliant with treatment significantly increase their risk of fatigue-related accidents and are at risk of losing their certification.

Can Aeroflow perform my sleep study? How much does it cost?

Aeroflow Healthcare offers in-home sleep testing devices that many people find are more convenient than going to a sleep lab. The test can be sent to your home with instructions for use and only requires one night of data. After we receive the sleep test device back in the mail, we will call you with your test results and if necessary, help you get set up on CPAP therapy. We can take one payment of $99.50 upon scheduling the study, then the remaining $99.50 one month later. Click here to schedule your sleep study.

I got a temporary DOT card but have to be screened for sleep apnea, what should I do now?

This temporary card is not renewable, so it is important that you act quickly to pass the DOT Physical Examination. You can either schedule your sleep study with your primary care physician, or with Aeroflow Industrial Clinics. Pending the results, your course of treatment will be outlined and must be followed in order to receive DOT clearance.

How do I know if I have sleep apnea?

Sleep apnea is a potentially-serious sleep condition typically seen in individuals who snore loudly, gasp for air during sleep and wake up with a sore/dry throat. Side effects of sleep apnea can be dangerous, and adhering to CPAP therapy is an effective way to treat the condition. You can take our online sleep screening to determine your level of risk for sleep apnea. However, the only way to diagnose sleep apnea is with a sleep study.
