Frequently Asked Questions

 

When will my order ship?

We are working hard to get orders fulfilled as soon as we can!

Due to the COVID-19 outbreak, our inventory has been quickly depleted. Fulfillments will occur on a first-come-first-serve basis. Unfortunately, we cannot provide definitive delivery dates until an order has successfully shipped and we receive a tracking number.

All purchases will now be final sale and will not be subjected to cancellation or refunds. This will help expedite our order fulfillment process and ensure that our customers receive their purchases as quickly as possible.

 

Do you ship to Hong Kong?

Hong Kong orders are shipping now and we aim to continue to fulfill new orders as fast as possible. However, due to ongoing shipping delays beyond our control we cannot and expressly do not guarantee any specific delivery date into Hong Kong at this time. You will receive a tracking number once your order has shipped. Place your order now to be among the first in queue. Thank you for your patience.

 

How long is the current queue for orders?

Unfortunately we do not have a specific date for orders to be fulfilled. This is subject to change and we will provide updates as more information becomes available. 

 

Will The O2 Curve help protect me against COVID-19?

The COVID-19 virus is very small. Most masks do not filter particles of its size and also do not seal well to your face, allowing virus particles to pass around the filter.

The O2 Curve’s medical-grade silicone provides a better seal. The mask is submersible and can withstand boiling water. The O2 Curve filters are capable of filtering ultra-fine particulate matter down to 0.1μm.

It is best practice to discard the O2 Curve filter and sanitize the entire mask after each use.

Wearing a mask is not sufficient to protect you from infection. Washing your hands frequently and avoiding close contact with others are recommended.

No mask is capable of protecting you 100% against any other dangerous substance or virus.  In particular, COVID-19 is a new virus that is not yet fully understood. We cannot and we expressly do not guarantee that our masks will protect you against COVID-19.

 

Does the O2 Curve have N95 certification?

Due to the compact design of the O2 Curve mask, it is not compatible with the N95 testing procedure. The filter media used in the O2 Curve is capable of filtering ultra-fine particulates. Tests with this material have achieved greater than 99% efficiency down to 0.1 microns.

In addition, the O2 Curve achieved a 98.6% efficiency for PM2.5 during tests performed at the University of Waterloo’s Green Energy and Pollution Control Research Lab. No mask is capable of guaranteeing 100% protection against viruses. However, due to its medical-grade silicone seal, the O2 Curve provides a better air-tight seal and fit than most cloth and disposable masks. The VFE efficiency for the filter membrane used in the O2 Curve achieved a VFE of 99.997% in tests performed by Nelson Laboratories with a mean particle size of 2.7µm.

How often should I replace the O2 Curve’s filter?

How often you should replace your filter depends on usage and the environment it’s used in. For general use, such as pollution filtration, the filter should last 1 to 2 weeks. In very dusty environments, you may need to switch the filter more often.

When protecting against viruses, the filter should be disposed of each time the mask is removed. It is also recommended that the mask be completely sanitized between uses.

Health measures that work for some people may not necessarily work for others. Different people have different levels of sensitivity, and as such, may require different types of masks to protect against the same type and concentration of substance. A mask improperly used may do little to protect you from any offending substance and may even worsen your exposure in some cases.

 

What does the O2 Curve filter?

The O2 Curve’s replaceable electrostatic filters provide filtration for particulate matter as small as 0.1 microns. With 98.6% filtration efficiency for PM2.5, it can be used to filter bacteria, pollen, mold spores, air pollution, road dust, sawdust, metal dust, drywall dust, airborne particles from wildfires, and other PM2.5 particles.

How Do I Clean the O2 Curve?


When cleaning the O2 Curve remove the filter and sanitize the seal, shell and inner lattice. This can be performed in a variety of ways. The O2 Curve is capable of being boiled or used in a dishwasher. Additionally, the O2 Curve can be hand washed with soap and water and air dried in a non-contaminated environment. Finally, a sanitizing wipe is also an option to keep the O2 Curve as clean and bacteria-free as possible. When protecting against viruses, the O2 Curve filters are recommended to be replaced after each use and handled with disposable gloves to avoid potential contamination. This guide is a best practice recommendation and will not guarantee protection against contracting any illness or virus.
