Subscription – O2 Nano Mask

We are excited to offer a simple solution to always staying more protected with O2 Nano Mask technology. Whilst we all hope that the need for face masks is not indefinite, we want to make sure that our mask owners are always stocked with O2 Nano Filters. With our 3 and 6 month plans, get monthly deliveries of O2 Nano Filter or universally fitting (usable with most face masks) O2 Nano Filters.

1. Select a size and quantity

2. Choose a subscription length (3 or 6 months)

3. Receive discounted filters to your doorstep every month

The O2 Nano Mask was designed to be used for various activities. From strenuous exercise to a quick grocery trip, the amount and strength of air passed through the O2 Nano Filter differs greatly. For this reason, it is difficult to recommend exactly when the right time to change to a new filter is. The most stringent advice we can give, based on health agency guidelines is to change the filter as often as daily. However, we know that this may not be feasible for all wearers of the O2 Nano Mask. In Moderate air quality index (AQI) environments we recommend changing a filter anywhere under 60 hours of use. Depending on the environment and use of the mask, breathing may become increasingly difficult towards the 60 hour threshold.

Depending on your use of the mask, our 3-pack is designed to last you 1 - 2 months and 9-pack up to 6 months, per mask user.
