Water damage doesn’t just sit on the surface like an uninvited guest—it sneaks into drywall, flooring, and even the structure of your home. If moisture isn’t handled properly, it can lead to mold growth, structural issues, and repairs that hit your wallet harder than expected.
At Florida State Construction & Restoration, drying isn’t guesswork—it’s calculated. By using air volume and square footage, we design precise drying plans that remove moisture efficiently and protect your property long-term.
Let’s break it down in a simple, no-headache way.
Why Air Volume Matters in Water Damage Drying
Drying fans (air movers) don’t just blow air around—they create controlled airflow that speeds up evaporation. But here’s the catch: using the wrong number of fans is like trying to dry a swimming pool with a hairdryer.
That’s where air volume calculations come in.
When properly planned, airflow based on square footage:
- Speeds up the drying process
- Reduces hidden moisture inside materials
- Helps control indoor humidity
- Lowers the risk of mold growth
It’s not about using more fans—it’s about using the right amount in the right places.
How to Calculate Air Volume for Drying
Before placing any fans, you need to understand how much air movement the space actually needs.
The basic formula looks like this:
Air Volume (CFM) = Square Footage × Ceiling Height × Air Changes per Hour (ACH)
Let’s make that less scary.
Imagine a 200 sq. ft. bathroom with an 8 ft. ceiling needing 6 air changes per hour:
200 × 8 × 6 = 9,600 CFM
That means your drying setup should produce enough airflow to handle 9,600 cubic feet per minute.
Why does this matter? Because guessing leads to slow drying… and slow drying leads to mold. Not exactly a combo you want.
