FAQ: Smart Cambridge Mask: You & Clean Air, Connected
For the most up-to-date information about the status of our project, check our project updates on Kickstarter!

What is the filter's lifespan?

For an average use in Beijing the masks last around 200 hours of use, around 3-6 months. The SmartValve tracks filter life carefully, so you won’t need to worry about monitoring filter level yourself.

Where do I get a new filter?

The whole mask is made of filters, so once they are saturated you will need to purchase a new ordinary mask. The SmartValve easily clips on and off so you can swap over to your new mask in a few seconds.

How does shipping work?

The SmartValve and Cambridge Mask are in separate packaging, but will be sent together. All pledge levels will be shipped at the same time.

How well should the mask fit?

It is important to ensure you mask has a goof fit. We have added adjustable ear loops to newer model masks to help users ensure the best possible fit. The mask filters are tested to meet NIOSH N99 standards, meaning filtration of 99+% of particulate pollution down to PM0.3

What does the mask filter?

The mask has three filters – the outer layer filters course pollution like dust. The middle filter is a three-ply non woven microfiber filter which can absorb particulate pollution down to 0.3 microns. This HEPA technology was developed by NASA for the Space Programme. The final inner layer is a 100% activated carbon cloth developed by the British military for use in chemical, nuclear and biological warfare protection. It is treated with silver which helps to absorb and kill viruses and bacteria and also absorbs gas based pollution such as benzene or petrol exhaust.

A basic list of things we filter: pet allergens, spores and pollen, PM2.5 and general particulate based air pollution down to PM0.3, gas based pollution, second hand cigarette smoke, viruses, bacteria, wood dust.

Does the mask come with the Smart Valve included?

We sell the mask and the SmartValve separately. There is a pledge level that includes both a mask and a SmartValve. All the masks we produce from October onwards will be compatible, so you can always buy the smart upgrade later on.

When can I get my mask and or SmartValve?

We aim to ship by October 2017.

Does the Bluetooth give off radiation?

We use Bluetooth Low Energy for our microchip. Normal Bluetooth transmits at a maximum of 100mW (far less than a mobile phone) and the Low Energy versions operate at one tenth of Bluetooth, or a maximum of 10mW. This means our masks will be a small fraction of the level you would find in mobile phone, wireless headphones or smart watches.

Are the masks for industrial use?

Our masks are not intended as workplace personal protective equipment (PPE). They should not be used in an industrial environment.

Is this suitable for people with multiple chemical sensitivity?

We work with Dr Harriet Leyland, a medical consultant and former General Practitioner. She also advises everyone to seek specific recommendations relating to their individual needs from their own doctor.

Are the mask certified to international standards?

Our mask filters are tested to the National Institute for Occupational Safety and Health standards for N99 under part CFR part 48. Nelson labs in USA tested mask samples and showed an average filtration of 99.6% of viruses and 99.7% of bacteria. We also meet Korean Food and Drug Administration, Chinese KN-95 and Indian national standards.

What do you do with my data?

We take privacy and your data very seriously. We use encryption for communications between the mask and your phone as well as phone and our server. We use data to improve our service and help customers have the best chance of respiratory health. This may include checking user breathing patterns (e.g. See the difference between someone walking, cycling or running), location (e.g. What areas are you going regularly which have pollution) or levels of interaction with our app. Once practicable we intend to give every account access to a downloadable csv file with all the data we have collected to be as open and transparent as possible and allow you to use the data for your own purposes.

BackerKit FAQ

What is BackerKit?

BackerKit is a service that crowdfunded project creators use to keep track of hundreds to tens of thousands of backers—from shipping details, pledge levels, preferences and quantities, whether they have paid or had their card declined, special notes, and everything in between!

The BackerKit software and support team is independent from the campaign’s project team—BackerKit does not handle the actual reward shipping. For more information about the preparation or delivery status of your rewards, please check the project's updates page.

How does BackerKit work?

After the campaign ends, the project creator will send you an email with a unique link to your survey. You can check out a walkthrough of the process here.

How do I update my shipping address?

BackerKit allows you to update your shipping address until the project is locked down for shipping. To update your address, go back to your BackerKit survey by inputting your email here.

I completed the survey, but haven't received my rewards yet. When will they arrive?

As BackerKit does not actually handle any rewards or shipping, the best way to stay updated on the shipping timeline would be to check out the project's updates page.

Why can’t I log into my account?

Request a login link to your survey by entering your email here:
https://cambridgemask.backerkit.com/

BackerKit will send you an automated email with an invite link to whatever email you pledged with.

I never received my invitation. How do I complete the survey?

The most common reasons for not receiving a survey email is that you may be checking an email inbox different from the email address you used to sign up with Kickstarter, Indiegogo or Tilt Pro account, or it may be caught in your spam filter.

Confirm that the email address you are searching matches the email address tied to your Kickstarter, Indiegogo, or Tilt Pro account. If that doesn’t work, then try checking your spam, junk or promotions folders. You can also search for "backerkit” in your inbox.

To resend the survey to yourself, visit the project page and input the email address associated with your Kickstarter, Indiegogo or Tilt Pro account.

When will my pledge will be shipped, charged or locked down?

That is handled directly by the project creator. BackerKit functions independently of the project itself, so we do not have control of their physical shipping timeline. If you want to check on the project’s status, we recommend reading over the project's updates page.

Can I upgrade or get multiple copies of my pledge?

This depends on the project creator’s decision. If you are unable to see the ‘Want to switch your pledge level?’ after clicking on your pledge amount under “Pledge Level” in your survey, then the project creator would prefer people not to switch pledge levels.
