Product & Technology
Sanitify goes beyond standard HEPA filtration by combining medical-grade HEPA H13 filters with our patented Microbiome Balancer technology. While regular purifiers only remove particles, Sanitify also restores beneficial microorganisms to your indoor environment, creating a healthier and more balanced airspace. Learn more on our Science page.
The Microbiome Balancer is Sanitify's patented probiotic dispersal system. It releases a controlled mist of Bacillus ferment probiotics into your air, which compete with and displace harmful bacteria on surfaces. This creates a protective microbial layer that actively works to keep your home healthier around the clock. See how it works.
HEPA H13 is a medical-grade filtration standard that captures 99.97% of airborne particles down to 0.3 microns. This includes dust, pollen, mould spores, pet dander, and fine particulate matter. The H13 classification is the same standard used in hospitals and clean rooms.
Sanitify operates at just 24 dB on its lowest setting, which is quieter than a whisper. Even at maximum speed, the unit stays below 48 dB. It is designed for continuous use in bedrooms, nurseries, and home offices without disturbing sleep or concentration.
One Sanitify unit effectively covers rooms up to 40 square metres (approximately 430 square feet). For larger open-plan spaces or whole-home coverage, we recommend the Combo Pack, which includes three units for multi-room placement.
No. Sanitify does not use ionisation or UV-C technology, so it produces zero ozone. Our filtration approach is entirely mechanical, using HEPA H13 and activated carbon filters. This makes it one of the safest air purifiers available for continuous home use.
Health & Safety
Yes, completely. Our Bacillus-based probiotics are FDA GRAS (Generally Recognised As Safe) certified and are non-toxic to dogs, cats, birds, and other household pets. These are the same probiotic species commonly found in animal supplements and veterinary products.
Absolutely. The Bacillus ferment used in Sanitify is a naturally occurring, non-pathogenic microorganism that is safe for all ages. Many parents choose Sanitify specifically because it creates a healthier microbial environment in nurseries and children's rooms without any chemical sprays.
Yes. The HEPA H13 filter captures 99.97% of common allergens including pollen, dust mites, mould spores, and pet dander. By continuously filtering the air, Sanitify significantly reduces airborne allergen concentrations. Many users report noticeable relief from hay fever and indoor allergy symptoms.
Sanitify can help reduce common asthma triggers such as dust, mould, and airborne irritants through HEPA H13 filtration. While it is not a medical device and cannot treat asthma, cleaner air with fewer particulates can support easier breathing. We recommend consulting your doctor for personalised advice.
Yes. Sanitify uses only mechanical filtration and natural probiotics with no chemicals, ionisation, or UV emissions. It is completely safe to use during pregnancy and can help ensure the air in your home is as clean and healthy as possible during this important time.
Maintenance & Filters
We recommend replacing the probiotic cartridge every 60 days for optimal microbiome balancing performance. The Sanitify app and on-device indicator will notify you when levels are running low so you never have to guess.
The HEPA H13 filter should be replaced every 6 to 12 months depending on usage and air quality conditions. In homes with pets or in high-pollution areas, you may need to replace it closer to the 6-month mark. The app tracks filter life and sends timely reminders.
The washable pre-filter can be removed and rinsed under lukewarm water every 2 to 4 weeks. Allow it to air-dry completely before reinserting. Regular pre-filter maintenance extends the lifespan of your HEPA filter and keeps performance at its best.
Yes. The Sanitify companion app monitors both the HEPA filter and probiotic cartridge levels in real time. You will receive push notifications when either component needs attention, along with one-tap reordering for quick replacement.
