Differential Pressure Monitors for Abatement and Remediation Containment
What Pressure Monitors Measure and Why It Matters
Differential pressure monitors measure the air pressure difference between the contained work area and the clean adjacent space during abatement and remediation projects. A properly operating containment with a functioning negative air machine maintains lower pressure inside than outside — typically 0.02 to 0.05 inches of water column negative. This pressure differential confirms that air flows inward through gaps and entry points rather than outward, preventing asbestos fibers, mold spores, or lead dust from migrating to occupied building areas. Without pressure monitoring, containment integrity is assumed rather than verified.
Regulatory Documentation and Data Logging
Continuous pressure logging records containment conditions throughout an abatement project, including periods when crews are busy and manual entries may be missed. Category options store time-stamped readings for later review. The PressurePro Model 1 keeps each job under its start and end dates in non-volatile internal memory, so records stay organized without extra paperwork. At closeout, contractors can print the job log on site with the onboard thermal printer or copy it to a flash drive through the USB Type A port for the client file.

Selecting the Right Monitor
Choose the RPM-RT1 for fixed monitoring built into a room. Its BACnet interface connects to the building system, and its range is ±0.10 inWC. The PPM3-S suits contractors who move one monitor between containments; its 16-day battery means fewer worries about finding power nearby. Choose the PressurePro Model 1 when the project needs a continuous record for each job and documented closeout, with on-site printing or transfer to a flash drive. It also has two programmable alarms and a Pressure Assist Outlet that can switch a connected negative air machine up to 2000 CFM.

Brio Air Filtration = Game Changer
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.

Bedroom machine
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!!
