SleepWeaver® Prevent: Combination CPAP/Filter Mask
Please click on a question to reveal the answer.
The SleepWeaver Prevent, combination filter/CPAP Mask is intended to provide an additional level of isolation for CPAP/NIV patients with known or suspected respiratory infections. This mask is intended for single-patient use in the home and single-patient use in the hospital / institutional environment. This mask is to be used on individuals who are greater than 66 lbs (30 kg).
SleepWeaver Prevent does not prevent or treat COVID-19. The filter on SleepWeaver Prevent is intended to reduce (but cannot eliminate) exhaled aerosolized particles being spread to the environment. All people who come in contact with a patient who may have COVID-19 should use protective gear and personal hygiene to prevent the transmission of the disease.
SleepWeaver Prevent has not been FDA cleared or approved. SleepWeaver Prevent has been authorized by the FDA under a EUA. SleepWeaver Prevent is authorized only for the duration of the COVID-19 Emergency Declaration.
SleepWeaver products are designed to work with all standard CPAP and Bi-level machines.
The exhalation “valve” on the SleepWeaver 3D portion of the mask is a series of very small holes that gently and quietly exhaust the exhaled air from the mask. These holes provide quiet operation without creating a jet of air that make a lot of noise. The KN95 portion of the mask covers these holes to reduce risks to those around the user.
The soft cloth portion of the mask is only available in one size and the headgear is available in regular and large. The most accurate measurement is directly under the jawline. If you measure 16 inches (41cm) or above, then you should consider the large size headgear. If you measure 16.5 inches (42 cm) or less, then you should consider the regular size headgear. The SleepWeaver Prevent is intended to be used on individuals who are greater than 66 lbs (30 kg).
You should make sure your measurements are accurate. If your measurement falls between the two headgear sizes, then you should try each size headgear to see which one provides the best fit. You can also review the fit tip video online at https://circadiance.com/preventvideos/.
No. The SleepWeaver Prevent is available only in blue with a white filter.
The cloth is the same material used to make winter ski clothing. A portion of the mask that contacts the skin contains polyester, nylon, and elastane. The cloth material is “breathable” meaning that the material wicks moisture and heat away from the user’s skin. The headgear consists of polyurethane foam, nylon, and lycra. The KN95 portion of the mask is made from five layers. Shell: Non-woven Fabric Filter: Meltblown (x2) Inner: Non-woven Fabric Earloop: Spandex Nose Clip: Aluminum
In the U.S., the SleepWeaver Prevent is covered under CMS codes A7034 & A7035 for Nasal Mask and Headgear.
Most users report that after the first night using our SleepWeaver product, it is the most comfortable mask they have ever tried! However, it can sometimes take longer than one night to become accustomed to new equipment, especially if you are new to CPAP and sleep therapy. Follow the instructions provided by your medical equipment supplier. We also encourage you to view the SleepWeaver Prevent videos, read the instructions, and call us for support if necessary (888-825-9640). Once you are comfortable with your new SleepWeaver Mask, you too will experience the restful sleep you have been missing.
With SleepWeaver Prevent, it is recommended you place the hose down towards the user’s chest, or off to either side. If you wish to direct the tubing over their head, i.e. behind the headboard of the bed, ensure that a sufficient length of tube is available so that no major kinks are in the tubing. Some PAP users connect 2 lengths of tubing to provide a longer hose which allows greater freedom of movement. Circadiance also sells the following accessories to assist in positioning the hose to your preference: Feather Weight Tub, Tether Straps, and Hose Clips.
The fitting on the SleepWeaver Prevent fits the 22mm ISO standard port which is used on most PAP Machines.
