  • The flexible silicone plugs seal the O2 Curve exhalation valves to create bidirectional filtration. We recommend using the Valve Plugs in combination with the Max Air Filters for improved breathability. 
  • Wearing a respirator protects you against the exhaled airborne droplets of those around you – installing the new O2 Curve Exhalation Valve Plugs allows you to protect yourself, and those around you as well.  
  • Upgrading your O2 Curve with Valve Plugs makes the product safe for travel, and adherent to airline mask guidelines. 

FAQ

Open tab

These are the top questions typically asked by people, but a full FAQ page is available for more information.

The O2 Curve uses a triboelectric charged filtration system, which consists of a hydrophobic outer shell that sandwiches a layer of melt blown filter medium. This filter system works both mechanically and electrostatically, and particles that are too small to be filtered physically are attracted to the charged filter, for improved filter efficiency and performance. The O2 Curve filters are designed to filter with greater than 99% efficiency down to a particle size of 0.1 µm, and independent lab testing confirmed filter efficiency of greater than 99% with particle sizes from 0.1 to 0.5 µm, using a flow rate of 236 L / min.

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 one to two weeks. In very dusty environments, you may need to switch the filter more often. 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.

Many viruses and bacteria are smaller than what any filter can remove. SARS-COV2, the virus responsible for COVID-19, is estimated to be 120 nm (0.12 µm) in size. However, viruses do not typically float in the air on their own, and are instead transported via droplets from sneezing, coughing, and even breathing. These droplets have a wide range in size, but are typically larger. Independent lab testing showed the O2 Curve filter had a virus filtration efficiency of 99.998%, with a mean particle size of 2.7 µm, and used a 31 nm (0.03 µm) virus.

Yes, the University of Waterloo Green Energy and Pollution Control Research Laboratory tested the O2 Curve against other commercially available respirators, with particles ranging from 0.5 µm to 4.7 µm. The O2 Curve outperformed the other respirators tested, which included a leading brand disposable N95 respirator, however it is important to note that this study did not specifically include the most penetrating particle size of 0.3 µm in the NIOSH N95 certification, and the testing methodology was not identical to the NIOSH standard. The University of Waterloo study used a flow rate of 32 L / min, which is based on the average work of breathing when doing light physical work. The NIOSH testing standard is 85 L / min, which is based on the average work of breathing when doing heavy physical work, or running at high speed.

Most masks do not filter particles of the size of the COVID-19 virus, and if they do not seal well to your face, they will allow virus particles to pass around the filter. The O2 Curve’s medical-grade silicone can provide an exceptional seal and our filter material is highly efficient at removing harmful particulate matter. The respirator is submersible and can withstand numerous cleaning methods. We recommend that it is best practice to appropriately discard the O2 Curve filter and sanitize the entire respirator after each use. Wearing any mask or respirator is not sufficient to protect you from infection. Depending on your environment, a respirator is just one of many practices that help protect you against the risk of infection. It is important to wash your hands frequently, avoid touching your eyes, nose and mouth, as well as avoiding close contact with others who may be infected. 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 respirators will protect you against COVID-19. However, if used appropriately in conjunction with other public health hygiene recommendations, it may substantially reduce your risk of receiving or transmitting the disease.

Shipping rates vary by region and by weight of the package. Most shipping rates are between $10-$20 USD.

Fulfills its purpose

The plugs do exactly what they're designed to do; it seals off the valves perfectly.

Easy

Easy to put in place. Breathability is okay with the thinner filter.

This was the answer to a wish

I was very pleased when I saw the new valve plugs. I love my Curve and have recommended it to friends, but always with the caveat that it's "a respirator, not a mask" and that it protects you but doesn't protect other people from you.

Now that problem is solved!

The plugs are well-designed, like everthing about the Curve mask, and fit perfectly.

Easy to install

The valves are easy to install in the skeleton of the mask and I was pleased to see that they were virtually hidden by the shell.

Easy to install

I like that it provides protection for others. Reduces capacity to exhale as easily and increases condensation in the mask slightly.

Thank you for the review, John! We are glad to hear that you are enjoying your valve plugs. If you aren't already, we suggest pairing them with the max air filters as they are 3x's more breathable than the original filters.
