Frequently Asked Questions

Why should I care about air?

Due to the home efficiency movement in the 70s, houses today are built like tight boxes, and that causes a number of problems that all result in bad air quality. First, a tight construction means poor ventilation. That's great at keeping your heated or cooled air in, thereby keeping your utility bills down, but it's terrible for trying to vent any pollutants out of your home. And there are many of those: VOCs from household products, mold, dust, pet dander, and cooking fumes. Not to mention all the outdoor air pollutants and pollen that your HVAC pulls in.

Your HVAC filter is equipped to capture some large particles, like dust. But it's designed to keep your HVAC system in good condition, free of particles that might lead to wear and tear. When it comes to purifying air, it makes very little difference.

At best, some particles (particularly larger ones) simply irritate your respiratory system upon contact, causing discomfort. At worst, some particles (such as PM2.5) get so deep in your lungs that they enter your bloodstream. Many particles are chemical toxins and carcinogens, which can lead to serious health consequences such as cancer and respiratory or heart conditions with prolonged exposure.

To talk about this, we have to understand what an asthma attack is: an instance in which the airways become inflamed and swollen, while the muscles around the airways contract and the airways produce extra mucous, making air passageways very narrow and breathing very difficult.Asthma is essentially caused by an overly sensitive immune system, and air pollutants such as pollen, pet dander, mold, dust mites, are all common triggers. Controlling your air quality is the best way to manage asthma.

Similar to managing asthma, managing allergy symptoms is best done by ensuring good air quality. Allergies are caused by immune reactions to air pollutants like dust, pollen, pet dander, and more. By removing pollutants, you remove allergy triggers.

No, we do not make any health claims or guarantees. Just like food, water, and lifestyle, air is a "health input," which means it is one of many factors that contributes to your health and wellbeing. We believe air is the most important health input, and we guarantee high quality air, which supports physical and mental wellbeing. But air quality cannot guarantee against health conditions.

Yes. When humidity is too high, it becomes easy for mold and dust mites to multiply. However, when it is too low, it can dry out the mucous membranes in your nose, eyes, and mouth, which your body relies on as its first line of defense against viruses and bacteria. The EPA recommends people keep indoor humidity levels between 30-50%. (Please note that Jaspr is not a humidifier or dehumidifier.)

What’s so special about Jaspr?

We rely on third party testing to back up our claims.

There are a few reasons: (1) Jaspr outperforms conventional air purifiers in capturing airborne pollutants, bacteria, and viruses, (2) Doctors don't want to deal with managing more devices or training their staff to take care of extra things; Jaspr's ease of use and smart mode means they barely have to pay attention to it, (3) Doctors and their staff consistently report that patients feel extra safe with Jaspr there, reflecting realtime air quality feedback.

First things first: did you know dentistry is ranked as one of the most dangerous jobs out there? It's because the high speed drills, air-water syringes, and ultrasonic scalers easily aerosolize saliva, blood, and other debris, which makes the risk of spreading viruses and bacteria very high. Dental offices manage this by leaving operatories empty between patients so that the airborne particles can settle. This period is called "fallow time," and it's typically 30 minutes to one hour long. But Jaspr cleans the air so quickly and thoroughly that fallow time is reduced to about eight minutes, which means dentists can see more patients while keeping everyone in the office safe.

In short: because conventional air purifiers don't even come close in performance. We come from a background of wildfire smoke and toxic mold restoration, where we used robust industrial air scrubbers to remediate air quality. When we tried typical $300-$600 air purifiers from hardware stores, they didn't even make a dent. The bigger surprise was when we discovered that those same conventional air purifiers weren't actually effective in residential settings either. And the problem was that naturally no one wanted a big, loud, ugly air scrubber in their home. So to solve that problem, we made Jaspr: a commercial-grade air purifier with premium components and top-shelf materials, designed to fit into your home. Like an air scrubber. But pretty and quiet.

Because it's ineffective and comes with a terrible warranty. See "Why do you keep comparing Jaspr to an air scrubber?"

Yes, the Jaspr filter is designed with a pre-filter layer that captures large particulates such as pet dander.

Ease of use was a top priority when we designed Jaspr. Just set it to smart mode, and Jaspr will automatically adjust its filter speed based on changes in your air quality.

At 30 dBa, Jaspr is literally as quiet as a whisper on its lowest setting. On its highest setting, it reaches 60 dBa, which is like the hum of your refrigerator.

UV light needs 6-60 seconds of consistent exposure to destroy >99.9% of a virus or bacteria, but air flows through a filter in about .35 seconds. This makes UV in air purifiers completely ineffective. Not only that, but UV can actually be harmful, as it causes oxygen (O2) to break apart, generating ozone (O3), which is a dangerous air pollutant. Exposure, even briefly, can cause respiratory issues and serious health conditions.

HEPA stands for high-efficiency particulate absorbing [filter]; these filters capture 99.97% of particles as small as 0.3 microns in size, effectively taking care of pollutants in the PM2.5 category. But there are different grades of HEPA filters, and Jaspr's filter goes above and beyond, capturing particulates as small as 35 nanometers (0.035 microns) at a rate of 99.7%, which means that if 1000 particles of this smallest size entered the filter, one to three particles might make it through to the other side.

Jaspr's PM2.5 sensor detects anything 2.5 microns and smaller. This means it focuses on the particle sizes that are most able to get into the deepest parts of our lungs, which pose the greatest health threat. Particles of this size include: dust, allergens, bioaerosols, a range of bacteria and viruses, and particles which carry bacteria and viruses. Jaspr's VOC sensor is configured to detect: benzene, alkanes, aromatics, olefins, halohydrocarbons, esters, aldehydes, and ketons. Note: While Jaspr's sensors detect this wide range of pollutants, Jaspr filters an even more extensive range of particulates.

No, radon is a radioactive isotope that is a natural product which comes off granite in the ground beneath some homes. The typical solution for radon mitigation is ventilation, not filtration.

We love plants, and there's nothing like a bit of green to make a space feel fresh. But fresh indoor air is another matter. Plants slowly absorb carbon dioxide and release oxygen, and they do also slowly absorb VOCs and some gases. But they're not fast enough to be effective, and they don't address other pollutants like dust, dander, mold, and allergens, which means they aren't sufficient to address indoor air quality needs.

Plastic is full of problems. Here are a few reasons it was never an option for us: It’s usually not recyclable. And in the cases that it is, it usually (a) ends up dumped in a landfill anyway, or (b) can only be recycled so many times before being down-cycled. It’s not durable. Cheap construction leads to bad warranties, which leads to a shorter lifecycle, and contributes to over-consumption. Pollution. For both of the above reasons, plastic is a huge contributor to pollution — and we’re trying to fight pollution, not make it worse. So instead, we made the Jaspr Pro out of steel, which solves all these problems.

Shipping & returns


Currently we ship to the continental United States and Canada.

Try it for 30 days (or we like to say 30 sleeps), and send it back within that timeframe if it's not for you.

Warranty, maintenance & filter replacement

The warranty is valid as long as users regularly replace the Jaspr filter every 4-6 months. We make this easy by offering the filter club, which is a subscription that automatically delivers replacement filters to you at your chosen interval. Not to mention, subscribers receive 30% off each replacement filter on this plan. The warranty is void if users opt out of the filter club, because irregular or delayed filter replacement can leave the unit vulnerable to wear and tear, meaning we can't ensure the performance or condition of the unit if its filter isn't being changed regularly.

Most conventional air purifiers are made with cheap components and materials, making them prone to degradation and breakage. Manufacturers would lose money because they would have to replace units too often. We think products that break easily are a problem, which is why we made Jaspr with the best materials possible.Most conventional air purifiers are made with cheap components and materials, making them prone to degradation and breakage.

One of our friendly team members will troubleshoot with you; when the problem is diagnosed, we'll send you a replacement part as needed.

Depending on your space and needs, a period of four to six months is usually adequate. For medical practitioners, a replacement interval of three months may be appropriate.

When you begin your filter club subscription, you'll select your preferred replacement interval (4 or 6 months). Filters will be shipped to you automatically, and your payment file will be charged at that time.

When filter replacement is skipped or neglected, a few things happen. First, the filter will become saturated and unable to capture new particles, making it clogged. As time goes by, this chokes airflow and puts a strain on the purifier's motor as it struggles to draw air in. This not only damages the unit, but can increase electricity bills. Second, a saturated filter can release particles back into your air and also become a breeding ground for mold and bacteria (remember, a filter captures particles but does not kill them). Last but not least, the air quality in your home will naturally deteriorate.
