D-piece ^™

$48.50 – $94.50

Options:
Item #: D-piece or D-piece-6
Includes: 12 Month Supply or 6 Month Supply

Features and Benefits:

One-way valve: Incorporates a one-way valve to prevent air being drawn back from the monitor.
Infection control filter: The D-piece™ valve filters have been independently tested for prevention of cross infection. We are happy to announce based on this data Bedfont concluded that bacterial and viral pathogens including (COVID-19 / SARS-COV-2) will effectively be removed by the D-piece™️ filter at an efficiency rate of >99% (bacteria) and >97% (viruses).
Patented design with resistance is based on clinical data (2010), which shows blowing slowly and fully represents a more accurate reading.^2,3 Also, new D-piece has been redesigned to slow the exhalation process, as data indicates that a slow, deliberate breath sample can increase the accuracy of your results by as much as 30%.

Features and Benefits	● One-way valve: Incorporates a one-way valve to prevent air being drawn back from the monitor. ● Infection control filter: The D-piece™ valve filters have been independently tested for prevention of cross infection. We are happy to announce based on this data Bedfont concluded that bacterial and viral pathogens including (COVID-19 / SARS-COV-2) will effectively be removed by the D-piece™️ filter at an efficiency rate of >99% (bacteria) and >97% (viruses). In the tests carried out on the viral and bacterial filter contained in the D-piece™️, the virus model used for tests (M2-Coliphage) are similar in size as the smallest human viruses (as small as 24 nanometers in diameter⁴, so that they can test the efficiencies of the filters for removing human viruses from air streams. The model virus (M2-Coliphage) is approximately 24-26 nanometers in size1 in comparison to COVID-19 virus which is approximately 125 nanometers in size.⁵ ● Patented design with resistance is based on clinical data (2010), which shows blowing slowly and fully represents a more accurate reading.^2,3 Also, new D-piece has been redesigned to slow the exhalation process, as data indicates that a slow, deliberate breath sample can increase the accuracy of your results by as much as 30%. ^1.Public Health England.

Nicotine & Tobacco Research published June 7 2010^{^3.}When measuring breath an acceptable level of back-pressure is required in order to ensure the testing procedure is comfortable to all patients, especially those with respiratory conditions such as asthma or COPD. This back-pressure is measured in millibar (mbar). The American Thoracic Society (ATS) and European Respiratory Society (ERS) recommend the level of back pressure to be between 5-20mbar2. The D-Piece restriction produces between 6 – 13mbar for normal to fast exhalations, therefore falling well within the recommendations set out by these expert bodies. ^4. Berkeywaterkb.com. 2020.
