Negative Air Machines: Create Negative Pressure Containment
Negative air machines create and maintain negative pressure inside containment areas to prevent contaminated air from escaping to clean spaces during mold remediation, asbestos abatement, lead removal, and other hazardous material handling operations. Proper negative pressure ensures all air flows into the work area through controlled entry points rather than leaking contaminated air to adjacent spaces. HEPA-filtered exhaust from negative air machines safely vents outside the building or to approved discharge areas while maintaining the pressure differential required by industry standards and regulations.
HEPA Filtration for Hazardous Applications
Negative air machines use true HEPA filters to capture 99.97% of particles at 0.3 microns, including hazardous materials like asbestos fibers, lead dust, mold spores, and other regulated contaminants. This filtration level meets EPA, OSHA, and industry requirements for remediation and abatement work where proper air handling is legally mandated. Certified HEPA negative air machines provide the documentation needed for regulatory compliance and protect workers from hazardous exposure during containment operations.

Variable CFM for Different Containment Sizes
Negative air machines offer variable CFM settings to match airflow to containment volume and achieve required air changes per hour for different project types. Higher CFM handles larger containment areas while lower settings suit smaller work zones without over-pressurizing. Calculate required negative air machine capacity based on containment volume and the air changes specified for your application, typically 4-6 for general containment and higher for hazardous material work. Multiple smaller negative air machines often provide better pressure distribution than a single large unit in complex containment configurations.
Verify negative pressure with manometer readings rather than assuming equipment is maintaining proper containment. Document pressure readings throughout projects for compliance records and quality assurance. Position machines to create effective airflow patterns that pull contaminated air through filtration before exhausting or recirculating.

This vacuum is very light and powerful
Gets the job done without hassle. This vacuum is powerful and reliable for everyday cleaning. Definitely recommend it.
we have three cats, and this purifier has done wonders in removing pet odors and dander
Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our home’s central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
this bedroom purifier has transformed my sleep quality. the air is so much fresher and cleaner worth every penny
very customer friendly and professional design.
perfect for maneuvering in tight areas the HEPA filter is a huge bonus
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
This vacuum has exceeded my expectations. It's super powerful and handles daily cleaning with ease. I recommend it to everyone.
really effective in sweeping up all kinds of debris from our warehouse floor
works wonders on tough carpet stains. it's compact and easy to use for upholstery cleaning too
this wide area vacuum covers large spaces quickly it’s a huge time saver for our warehouse cleaning
Covers a large area quickly, and the bag is easy to replace. Great for busy offices
