Description

The Smart Air Blast MKII HEPA Air Purifier is built for environments that need high-capacity particle removal, not marketing gimmicks. Designed as a powerful HEPA air purifier for home, large rooms, and offices, it delivers real airflow and tested filtration for entire houses, open-plan spaces, and shared indoor environments. With 1200 CFM of clean air, the Blast MKII can clean up to 4,500 sq ft in just 30 minutes, making it suitable for use as an entire house air purifier in large homes, as well as in offices, gyms, classrooms, and clinics where dust, allergens, and particulate pollution are the primary concern. How the HEPA-Only System Works ✔ True H13 HEPA filtration Captures 99.97% of particles ≥0.3 microns, including PM2.5, pollen, dust, mold spores, and fine particulate pollution. Through diffusion, the HEPA filter also captures ultra- fine particles down to 0.07 microns and smaller. ✔ HEPA-only configuration This model focuses on particle filtration only. If your environment includes smoke, odors, or chemical gases, the Blast MKII is compatible with a Smart Air activated carbon (VOC) filter, available separately. ✔ Washable pre-filter Traps pet hair, lint, and large dust to protect the HEPA filter, maintain airflow, and extend filter life. ✔ High airflow with controlled noise Operates at approximately 43 dBA on high & 29 dBA on low, balancing performance and comfort for continuous use in occupied spaces. ✔ Portable, large-format design Integrated wheels allow easy repositioning across rooms or floors, making it practical for large homes and facilities. ✔ Use Original Smart Air Filters To maintain tested airflow, filtration efficiency, and safety certifications, always use genuine Smart Air replacement filters: Smart Air Blast H13 HEPA Filter - ASIN B0929FWFF8 Smart Air Blast Activated Carbon (VOC) Filter - ASIN B0929D6GDP Using original filters ensures the Blast MKII continues to perform as designed and tested. Choose the Smart Air Blast MKII HEPA Air Purifier if you’re looking for a high-capacity HEPA air purifier for home, large rooms, or offices, with the flexibility to add carbon filtration later using genuine Smart Air filters for consistent, reliable performance.

  • Best all around air purifier for large spaces
Size: Blast For Large Spaces HEPA Only
When looking at air purifiers 3 key things matter: 1. CFM - This unit has one of the highest if not highest cfms available 2. Noise level - This is one of if not the quietest units available 3. Cost for filter replacement - Filters for this unit are reasonably priced and long lasting. I've had this air purifier over a year and couldn't be happier. ... show more

  • large quiet simple HEPA filter
Size: Blast For Large Spaces HEPA Only
I love it. It is keeping our main floor air quality where it needs to be for our health. It's a bit bigger than I expected. Sadly, it arrived with a few transport dents. But, it works out of the box.

  • Good Purchase
Size: Blast For Large Spaces HEPA Only
Works great. I have a German Shepherd and the dog smell is completely gone in a sizeable condo. Runs quietly and sets up very easily. There is a noticeable difference in the air's cleanliness from night to day.
