Enjoy Instant Relief from Allergies and Pollutants in Your Personal Bubble of Fresh, Clean Air

Sprimo angled upwards

What is Sprimo?

Sprimo is a personal, portable air purifier that is scientifically proven to be 50 times more effective and efficient than conventional air purifiers at removing pollution and particulates from the air.

It instantly envelops you in a quiet, soft bubble of fresh, clean air, whether you are in a small room or a large open space. Say goodbye to itchy eyes, sneezing, and your office-mate’s germs! Not only is the air cleaner, but it arrives within seconds rather than hours, and at a fraction of the price of conventional purifiers and filters.

How Does it Work?

Sprimo is armed with state-of-the-art sensors that monitor the quality of the surrounding air, collecting data so that Sprimo can adaptively make the air cleaner, while personalizing how air is delivered to you based on your specific needs and preferences. Connect your Sprimo to the Sprimo mobile app to control your air purifier remotely, and get real-time insights into the quality of the air around you.

Sprimo was developed by an expert team that includes a Ph.D. in chemistry from NYU specializing in indoor air quality, a product manager behind development of the Amazon Kindle, and an industrial designer responsible for the Nike Fuel band, the Dropcam camera, and Google Chromecast. We’ve been working on Sprimo for the last two years and putting it through rigorous testing at UC Berkeley. With your help as our first backers, we are ready to raise the bar for air purification.

Get Healthy Air in Any Room, Instantly

Fits easily on your desk. Keep the air in your office sweet and clean.

Got a workmate who smokes? Has cats? Likes curry? Or maybe someone near your desk, um, let’s say is trying to solve the drought by reducing shower schedules? Get sweet smelling, clean air in any office.

Put Sprimo on your night stand for a good night's sleep and relief from allergies without meds.

At night it’s like sleeping under a fresh blanket of air from the Alps. By removing toxins from the air around you, Sprimo gives you instant relief from allergies, so you can get a better night’s sleep without using medication.

Protect Yourself From Harmful Pollutants and Particles

While in use, Sprimo is pointed directly at the user while it quietly emits a soft stream of purified air. Sprimo forms the clean air into a smooth, laminar flow, which becomes turbulent shortly after exiting the body. This forms the bubble of fresh air that surrounds the user.

Wait! Did I just hear someone sneeze?

Easy To Use Touchscreen

Sprimo includes a 2.5” round touchscreen where you can access air quality information, fan speed, and filter status.

You can also control how much air is generated by manually adjusting the fan speed from 0 to 100. (no High-Med-Low with Sprimo). If you need a cool fan, simply turn up the fan speed.

Another function allows you to see the status of your filter capacity. And when the filter is getting close to full, Sprimo lets you know so you can order a replacement.

Sprimo’s app lets you check levels on your phone - in real time, so you can monitor or adjust Sprimo’s settings remotely. It’s that easy.

Sprimo’s touch screen can also show you in air quality levels in real time.

Designed to work for YOU

What makes for a good product? A high quality product that works for YOU, not the other way around. If Sprimo senses that today is a bit extra muggy than yesterday, it will adjust and work harder to keep you safe.

Sprimo keeps you informed of your indoor air quality and will notify you when there’s anything to worry about, like dust levels or unseen gasses.

Because Sprimo is smart, it will change its behavior based on measurements (gasses, dust, pollen, temperature) that it takes. Sprimo can let you know if your humidity level is extremely high, or if the CO2 level has risen sharply. It will even notify you a couple weeks ahead of time if the filter’s capacity is diminished, and the smartphone app will let you know when a new filter is on its way.

Sprimo is Quiet Enough for Your Library, if You Only Had One…

Gorgeous Design, Inside and Out

Sprimo front view

It tilts, so you can direct air exactly where you want it. Sprimo’s touchscreen and home button are all you need - no knobs.

The body tilts with the kind of friction hinges used in laptops. Sprimo pulls bad air from the back, and delivers fresh air out of the front.

Sprimo’s Filter

For this campaign, only one general-purpose filter is available. However, as we gather data about our users’ air quality and needs, we will offer other types of filters in various combinations.

Sprimo uses a built-in NFC reader to read the filter is currently installed, along with details such as when the filter was manufactured. This tells Sprimo how much total capacity the filter has, how much filter life it has, and what it has been optimized to capture.

Replaceable in Just Seconds

This must be a first - a filter designed to be so simple my grandmother can replace it. Talk about turning the industry on it’s ear!

Sprimo’s filter can be replaced in seconds with one hand and no tools. Simply twist and pull to remove. Similarly, to install a new filter, simply insert and twist.

Replace Filter Based on Usage and Air Quality

Because Sprimo knows exactly how much air it has filtered, the quality of that air, and the type of filter currently installed, it can alert you to change its filter based on actual use, not on a fixed interval of time regardless of use like other air purifiers.

We Recycle Used Filters

Just use the packaging from your new filter to send us back your used one, and we’ll break it down for recycling.

Clean an Entire Room Using Turbo Mode

In turbo mode, Sprimo’s body is pointed straight up and you can have the fan turned on full blast. The purified air exiting the body is split by the aluminum handle, which diffuses the air throughout the room. This lets Sprimo quickly purify all the air in the space. It looks technical, but don’t worry, it’s just science.

Tilting the body so the air points straight up is the best way to clean a whole room.

Looking Good on the Credenza.

You Are What You Breathe

You consume about a kilo of food every day, about 2 kilos of water every day and you consume nearly 20 lbs of air every day. (I didn’t know that!) But we all know it’s critical to your well being, your energy level, and your lifespan.

Polluted air kills around four million people a year, and the incidence of childhood asthma has doubled in the last ten years. Petrochemicals, toxins, and “cleaners” added to household products borders on low-grade chemical warfare.

Do you know what's really in your air?

A conventional air purifier is simple - a fan forces air through a filter. Yet, typically only 1% of the purified air output is actually inhaled by an occupant of the space. Even then, that air is often no longer clean by the time it reaches the occupant’s lungs - the many pollution sources (e.g., building materials, cleaning products) that make indoor air quality two to five times worse than outdoor have already infested the newly “purified” air.

But what if the problem in your room isn’t dust, dander, or pollen, but volatile organic compounds (VOCs)? How do you choose a filter when pollen counts are expected to go through the roof due to this year’s strong El Nino, but the main pollutants in your region are particulate matter up to 2.5 microns in diameter (PM2.5)? How do you know if the throughput of the heavy box chugging away loudly in the corner is any match for a cavernous, musty basement with twenty year-old shag carpet, two kids, three dogs, and a cat with dandruff? Without expensive, ongoing testing you don’t know. Unless you have Sprimo.

How is Sprimo Different?

Risks and Challenges

While we have put together a solid production plan surrounding the Sprimo, we know things do come up. While we do not expect any issues, here are some challenges that could potentially arise:

  • Unexpected increases in costs. To mitigate this risk, we've spoken to six different manufacturers to get quotes and to understand where the manufacturing risks lie, and to understand their capabilities.
  • Availability of key components. Even though we purposely chose off-the-shelf components wherever possible, it's always possible some parts may not be available when we need them.
  • Development time could be much longer than estimated. Hardware or software development could possibly be impacted by unforeseen technical challenges. That's why we have consulted with over a dozen advisors and experts in hardware and software product development to anticipate the tough parts.
  • Loss of key personnel. As with any company, key contributors in Sprimo or our supply chain could leave or otherwise be unable to perform, possibly affecting scheduling and delivery.

Frequently Asked Questions:

Q: What size room does it filter?
A: Because Sprimo surrounds you with a bubble of purified, clean air (rather than wasting time trying to clean a larger space) it can be used in any room size. Sprimo focuses it’s efforts on keeping the air in YOUR personal space pure, not the air on the other side of the room.

Q: Is it loud?
A: While Sprimo is quieter than other air filters on the market, it does generate a low hum (like any fan).

Q: Why are you 50 x better than others?
A: The short answer - Sprimo’s purification method of cleaning your personal space rather than a whole room is is more efficient, effective, and smarter.
The long answer - see campaign page above :).

Q: Where does the air go in, and come out?
A: Air is pulled in through the back edges of Sprimo (where you can see the blue of the filter), and clean air is then pushed out the front of Sprimo’s face (around the edges of the touch interface). See the image below for more details.
