Frequently Asked Questions
Mask Valve Information
The EasyFlow mask™ uses electrostatic filter media to achieve its notable breathability, while still providing excellent sub-micron filtration between .1 and .3 microns. Extreme heat and moisture are two factors that may reduce filter efficiency. We have integrated a unique moisture vent system to allow for better moisture control in warm outdoor conditions or during intense physical activity. This moisture vent does not allow as much unfiltered exhalation as typical exhalation valves; however, it is recommended that you filter the valve when this vent is not needed. The filter cutout is several millimeters smaller than the seal point of the disc to prevent leakage. As of September 2020 we also provide filters with no valve cutout as we head into the cooler months. When using the no-hole filters you may either remove the silicone disc or leave it in place.
Filtering The Valve
A piece of filter about the size of the silicone disc can be cut and layered with the main filter to seal the valve. When assembling the mask, place this cut piece first on the outer frame, then place the main filter over it and ensure the entire hole of the main filter is covered. The circular ridge on the outer frame was specifically designed and placed to hold this extra piece in place to filter the valve as needed.
The EasyFlow Mask™ is a one size fits most product, designed with flexibility in mind. The upper and lower portions were designed to be moved up and down several inches to fit many facial types. The slider included with the strap is not intended to hold tension, rather it is there to help find the best fit. Once you have found your desired level of tension, pinch the straps at the slider, remove the upper strap and tie it in a bow to lock in place.
Adjustments For Nose Rubbing
The shallow nature of our F0230 mask is required for many clinicians to preserve downward visibility, layer other PPE and allow the use of medical optics, cameras, loops, lights, etc. Our unique design was created to combine the low-profile fitment of a surgical mask with the tighter fitting, sub-micron filtration of a respirator.
Users with larger noses who experience some rubbing on the inner frame may trim away some of the circular inner frame portions for a more customized fit. Doing so will free a bit more space and allow the nose to touch the felt, instead of the plastic, for a more traditional mask feel. The perimeter of the inner frame and gasket should not be adjusted, so a proper seal is still achieved.
All modifications are done at the users own risk.
