- The pods feel too small and don’t seal completely.
Duos come in two sizes, medium and small. If you feel the Duos should fit more snugly, please let us know what size product you have (visible on the sample box in a box reading S or M) so we can adjust or consider the need for an extra size.
- When should I wear the product?
Outside and on the subway in polluted areas or if you are experiencing dust or pollen in the air. Most modern buildings, vehicles and offices are equipped with air-filtering systems.
- How long can I wear the product for?
Although there is no prescribed limit to how long you should wear the pods, we don’t anticipate use of more than a few hours at a time. We want to hear what your experience is with wearing the pods and will be in touch after the test period.
- Will wearing Duos affect my breathing?
We believe comfort is a primary requirement for the success of Duo. We are still developing our filters to make it easier to breathe through them. Depending on which filter samples you were given, breathability will be different. Let us know how you feel about comfort to help us refine our product.
- What particles am I protected against?
Duos are targeting PM2.5 particles which includes most of airborne pollution, they are about 40 times smaller than a human hair! They also capture larger particles like dust and pollen.
- Does Duo protect against COVID-19?
Viruses come in many sizes, although Duos primarily focus on PM2.5 particles, COVID-19 is large enough that about 60% of virus agents will be stopped by the filter. However, Duo is not rated as a safety device for viral protection and only filters air going into the nose. It does not protect against infection through eyes or the mouth. Please refer to recommended guidelines from authorities when choosing critical protection in cases where caution is advised.
