Product & Technology
What is HEPA 14 filtration? HEPA 14 is a medical-grade air filtration standard defined by EN 1822. It captures 99.995% of airborne particles at 0.3 microns — the most penetrating particle size. This is the same filtration grade used in hospitals, pharmaceutical cleanrooms, and surgical suites. The AirPro’s HEPA 14 filter captures 99.9% of particles as small as 0.1 microns, including bacteria, mold spores, pollen, dust mites, and fine particulate matter. What does the UV-C sterilization function do? The UV-C light inside the AirPro provides an additional layer of germicidal sterilization. UV-C light at 254 nm wavelength damages the DNA of bacteria, viruses, and mold spores that pass through the filter, neutralizing them. The UV-C light operates inside the sealed unit and does not expose users to UV radiation. What are the 3 stages of filtration? Stage 1: Pre-Filter captures large particles like dust, hair, and pet dander. Stage 2: HEPA 14 filter with antibacterial coating traps 99.9% of ultra-fine particles down to 0.1 microns. Stage 3: Activated carbon filter absorbs odors, smoke, and volatile organic compounds (VOCs). The UV-C sterilization function provides additional germicidal treatment. How is HEPA 14 different from regular HEPA filters? Standard HEPA (sometimes called HEPA 13 or “True HEPA”) captures 99.95%–99.97% of particles at 0.3 microns. HEPA 14 captures 99.995% — allowing 10 times fewer particles to pass through. See HEPA 14 vs HEPA 13 for a detailed comparison. What is the 360-degree airflow design? The AirPro draws air from all directions around the unit, rather than from a single intake. This maximizes air circulation and ensures even coverage throughout the room without needing to position the unit in a specific orientation.Setup & Use
How do I set up the AirPro? Remove the AirPro from its packaging, remove the protective wrapping from the filter inside the unit, place the filter back inside, plug in the unit, and press the power button. No app or Wi-Fi setup is required. What room size does the AirPro cover? The AirPro covers 430 sq ft in 10 minutes and up to 1,200 sq ft in 30 minutes. For best results in larger rooms, position the unit centrally with clear airflow around all sides. How loud is the AirPro? The AirPro operates between 25 and 50 dB depending on the fan speed. Night Mode runs at 25 dB — quieter than a whisper. For context, a library is typically around 40 dB and normal conversation is about 60 dB. What is Night Mode? Night Mode reduces the fan speed to its lowest setting (25 dB) and dims all indicator lights for undisturbed sleep. The purifier continues to clean the air effectively at this reduced speed. How does the Smart Timer work? The Smart Timer allows you to set the AirPro to run for 2, 4, or 6 hours, after which it automatically shuts off. This is useful for running the purifier while you sleep or while you are away. What is the aromatherapy feature? The AirPro includes an aromatherapy pad where you can add a few drops of your favorite essential oil. As the purifier circulates air, it diffuses the scent throughout the room. The pad is separate from the filtration system and does not affect filter performance. Is the AirPro safe for babies, children, and pets? Yes. The AirPro uses no ozone-generating ionizers. The UV-C light is fully enclosed within the unit, so there is no UV exposure. The 25 dB Night Mode is quiet enough for nurseries and bedrooms. The HEPA 14 filter is particularly beneficial for infants and pets who are more sensitive to airborne allergens and particulates. How much electricity does the AirPro use, and is it cheap to run continuously? The AirPro is designed for low energy consumption and continuous, around-the-clock operation, and it runs on a standard household outlet. Lower fan speeds and Night Mode draw the least power, while higher speeds use more. For the exact wattage of your unit, check the rating label on the purifier or the user manual — as an energy-efficient HEPA purifier, its ongoing running cost is modest.Filtration & Air Quality
What does the AirPro remove from the air? The AirPro removes pollen, dust, dust mites, pet dander, mold spores, bacteria, smoke particles, VOCs (volatile organic compounds), cooking odors, and fine particulate matter (PM2.5 and smaller). The activated carbon stage specifically targets gases and odors that particle filters cannot capture. Does the AirPro produce ozone? No. The AirPro does not use ionization technology and does not produce ozone. It relies solely on mechanical filtration (HEPA 14), activated carbon adsorption, and UV-C sterilization. Can the AirPro help with allergies and asthma? Yes. HEPA 14 filtration removes common allergy and asthma triggers including pollen, dust mites, mold spores, and pet dander at a higher efficiency than standard HEPA filters. The 0.1-micron capture capability addresses ultra-fine particles that lower-grade filters miss. What is the smart lifetime filter tracking? The AirPro has a built-in monitoring system that tracks cumulative filter usage. An indicator light alerts you when it is time to replace the filter, removing guesswork and ensuring your air quality remains consistently high.Maintenance
How often do I need to replace the filter? Every 6 to 12 months, depending on usage intensity and air quality conditions. Homes with pets, smokers, or high dust levels may need more frequent replacement. The built-in filter tracking indicator will alert you when replacement is needed. Can I wash or vacuum the HEPA 14 filter? No. The HEPA 14 filter cannot be washed, rinsed, or vacuumed. Doing so will damage the filter media and compromise its 99.995% filtration efficiency. When the filter indicator signals replacement, install a new replacement filter. Can I clean the pre-filter? Yes. The pre-filter can be gently vacuumed with a brush attachment to remove accumulated dust and hair. This can extend the life of the HEPA 14 filter behind it. How much do replacement filters cost? Replacement filters are available at SonoHealth.com: 49.99 for a 2-pack, or $79.99 for a 4-pack. The filter subscription saves 20% and ships automatically every 90 days. What is the filter subscription? The SonoHealth filter subscription delivers replacement filters every 90 days at 20% off the standard price.
