Miami Beach Mold Customers: Learn the benefits of "Negative Air"

Hopefully you will hear your remediator in Miami discuss the topic of "negative air" when planning out your mold remediation job.

Negative air is a commonly misunderstood concept, yet critical to implement.  It refers to negative air pressurization. For our purposes, it is an important practice to implement when conducting mold remediation jobs, to prevent cross contamination. In other words, negative air pressurization is used to make sure that contaminants don't go into surrounding areas, beyond the work zone where demolition is taking place.

Take a look at the attached photo. Most noticeably you'll see a temporary room cordoned off by heavy plastic. As you can imagine, our SERVPRO team was conducting demolition in this area. The plastic of course is designed to help keep contaminants that spring free when tearing out walls. However it isn't the only tool we use. Check out how the plastic is sucking in toward the insides of the little temporary room we created. This is because we established negative air, by sending out of the little room filtered air through a HEPA-filtered air scrubber. As a result, the air pressure (air flow) is rushing from outside the barrier (the clean areas) toward the dirty work zone areas. This prevents contaminants from spreading.

Many people even in our industry don't understand the term. If you have a project ongoing and are concerned that maybe your remediator isn't altogether sure of what he or she is doing, give us a call at (305) 532-5411 for a free consultation, we'll be happy to help out. Or, you could email us at jhrbek@SERVPROmiamibeach.com
