What’s in the box: One Air Pro with one PECO-HEPA Tri Power filter

Inside every Molekule, our unique PECO-HEPA Tri-Power filter features the combined forces of our own patented PECO technology that destroys viruses, bacteria, mold, allergens, VOCs, and more; True HEPA 99.97% particle-capture efficiency rate; and a layer of carbon filtration to reduce odors and toxic gases.

Molekule destroys the widest range of pollutants compared to conventional purifiers.

There’s more in your air than you think. Allergens, chemicals, bacteria, mold, and other airborne offenders are waiting to make you sniffle, sneeze or worse.

Air Pro destroys any organic pollutant that enters the air intake. Revolutionary, patented PECO technology breaks down organic matter at a molecular level, inactivating harmful pathogens and turning VOCs, viruses, bacteria, mold spores and more into harmless gases like carbon dioxide and water vapor. Air Pro destroys allergens (dust mites, airborne mold spores, pet and cockroach dander, pollen), volatile organic compounds (formaldehyde, benzene), bacteria, viruses (H1N1, SARS-CoV-2)*, particulate matter and toxic gases found in smoke, and so much more.

*No air purifier can prevent transmission of a virus. Molekule recommends use of PPE and following directions of the CDC and other government authorities.

Yes, Molekule Air Pro comes with our PECO + HEPA TriPower filters. Smoke particles are trapped with HEPA efficiency, toxic gasses are quickly removed with activated carbon, and PECO provides another layer of protection by destroying the organic substances that are common in wildfire smoke. When set to Auto-Protect mode, Air Pro will automatically increase power when pollution levels rise, even when you're asleep. Air Pro can detect 3 sizes of particles so you can know in real-time how wildfire smoke is impacting your indoor air quality.

The Air Pro can remove common airborne allergens such as pollen, dust mites, pet dander, and mold spores from the air to help with allergies. It uses a combination of PECO and HEPA filtration technology to capture and destroy these particles at a molecular level, providing relief from allergy symptoms. In fact, PECO technology has been independently tested and shown to capture 95% of airborne allergens, making it an effective solution for allergy sufferers.

Those who suffer from asthma are even more susceptible to compromised air quality. Both the Molekule Air Pro and Air Mini+ with PECO-HEPA Tri-Power filter are excellent options for sensitive groups. The Tri-Power filter can help remove asthma triggers in the air by first capturing pollutants and irritants with HEPA filtration, then PECO technology breaks them down further into harmless carbon dioxide and water. Air Pro and Air Mini+ use sensors to detect pollution in the air and adjust fan speed to combat pollutants like pet dander, wildfire smoke, and more.

PECO destroys what HEPA leaves behind.

Not one, but three layers of protection. True HEPA captures 99.97% of small particles while light-activated PECO technology destroys organic pollutants and a layer of carbon removes odors and gases.

An operating system for your air quality.

Keep an eye on your air quality with daily and weekly air history stats. Track changes to particle levels in five-minute increments or going back as far as the previous four weeks.

Automatic Protection

Auto Protect mode enables Air Pro to automatically adjust fan speeds when it senses spikes in particle and chemical levels. Quiet mode does it silently. Just sit back and let Air Pro take care of the air for you.

What else do you want to know?

The Molekule Air Pro and Air Mini+ differ in their room coverage and overall size. The much larger Air Pro has a higher air flow rate and is designed to improve indoor air quality in larger rooms up to 1000 square feet. Meanwhile, the Air Mini+ is made for smaller rooms up to 250 square feet. Both products also have differences in mobility. The Air Pro has a built-in handle and caster wheels for easy maneuvering, while the Air Mini+ is more compact and portable for travel or use in smaller spaces. Choosing the right air purifier starts with identifying your needs and preferences.

The Air Pro purifier operates at a noise level of 30-65 decibels, depending on the fan speed setting. At its lowest speed setting, the noise level is comparable to a whisper, and at its highest setting, it is similar to the sound of normal conversation. Molekule has manufactured this product with a quiet mode, in addition to its standard mode for the Auto Protect function, sleep mode, or quiet mode, that runs at a low noise level to avoid disturbing sleep, making it suitable for use in bedrooms and other quiet spaces up to 1000 square feet.

Pet dander, or skin flakes, from cats, dogs, and other co-habitants can trigger minor to severe allergies or asthma. Running Air Pro in your home helps to remove the tiniest free-floating bits with HEPA efficiency, and then neutralizes them with PECO for even more protection. Air Pro can also measure CO2 to let you know if pet dander or other contaminants could be accumulating due to poor ventilation.

We recommend replacing the filter every 6 months. However, this life could be shortened by working to clean particularly dirty air like that from a commercial kitchen or during a wildfire emergency.

    Satisfied with Customer Service

    I has purchased the Air Pro and after a few months it attempted a software update. The screen became stuck in update mode and I was unable to remedy the glitch, even with guidance from customer service. Customer service was thorough and eventually sent me a refurbished Air Pro at no cost, with a new PECO-filter inside. While I was upset with the software glitch, I was satisfied with the replacement (although I would have given a 5 star review if I had received a new Air Pro instead of a refurbished one.)

    It just ok…

    Nothing to write home about. It constantly tells me my air is “bad” and runs faster and louder. Nothing I do seems to help my air get a better reading. Would I buy again…. NO. Save your money. Find a better unit

    Hi Amber, we're sorry to hear that, but we appreciate you taking the time to write in. If you're finding that the unit is always running on "Bad" it sounds like your sensors may need a recalibration. Reach out to and a support rep will be happy to assist you with this.
