IAQ for Renovation Sites

Why is air quality management necessary at a renovation site?
During the renovation and construction period, a large amount of dust, PM2.5, formaldehyde and TVOC (volatile organic compounds) are often generated on site. These pollutants not only affect the health of construction workers, but may also seep into other spaces that have been put into use, causing odor residue and risks to subsequent use.
Many sites rely solely on opening windows for ventilation, but the direction of airflow is uncontrollable, often leading to the spread of pollution rather than its effective removal. The truly effective approach is to control pollution at its source through systematic air purification and airflow management.

MoAir's solutions of IAQ for renovation sites.
MoAir does not simply provide single devices, but rather offers comprehensive solutions centered on "on-site air quality management," tailored to different construction environments:
Dust and PM2.5 filtration
TVOC / Formaldehyde Adsorption Treatment
Positive pressure and airflow path control
Integrating fresh air and exhaust systems
Real-time on-site monitoring and data verification
This transforms the air quality at the renovation site from "uncontrollable" to "manageable, measurable, and verifiable."
Core control focus of IAQ for renovation sites
Dust and particulate matter control
Through a multi-layer filtration system (including a pre-filter and a high-efficiency filter), the concentration of PM2.5 and fine particulate matter generated during construction is effectively reduced.
TVOC and odor control
Highly efficient adsorption filter material is configured to target volatile organic compounds released from paints, adhesives, and boards, significantly reducing pungent odors and harmful gas concentrations.
Positive pressure and airflow path design
The positive pressure design prevents polluted air from spilling into other areas, and the clear air intake and exhaust paths ensure that pollutants are effectively removed rather than circulated indoors.
Integrating fresh air and ventilation
While filtering and controlling pollution, it is also necessary to replenish fresh air to avoid oxygen deficiency or excessive carbon dioxide concentration in the space.

It's not about "installing a few machines," but about "systematic planning."
Managing air quality at a renovation site is not simply a matter of calculating the number of air purifiers to place based on the available space; it requires consideration of:
Space volume and partition status
Construction items and pollution intensity
Air volume requirements and air exchange rate
Airflow path and pressure balance
Filter pressure loss and actual effective air volume
MoAir will plan the overall system configuration based on the site conditions, rather than applying a standard solution.
Import process
Understanding on-site needs of IAQ for renovation sites and confirming construction type
Air quality status assessment (PM2.5, TVOC, etc.)
System design plan (air volume, filtration, airflow path, positive pressure)
Equipment introduction and on-site deployment
Data measurement and effect verification before and after import
Use data, not feelings.
In the MoAir project, actual measurement data will be presented:
Changes in PM2.5 concentration before and after introduction
Changes in TVOC concentration before and after importation
Trends in improving on-site air quality
This allows owners, contractors, and users to clearly see the actual improvement results.
Applicable venues
Hospital and clinic renovation projects
Office and commercial space decoration
Department store and shopping mall renovation projects
Construction of cleanrooms or spaces requiring high cleanliness
Construction work in sections within the already operational space
Not just during construction, but the starting point for long-term quality.
Moving air quality management forward to the construction phase can not only improve the construction environment but also significantly reduce the risk of residual pollution, thus establishing a better air quality foundation for the space after it is officially put into use.
