Carpet blowers are engineered for efficient drying and are more reliable for water damage restoration compared to regular fans.
Energy Usage And Cost Considerations
Carpet blowers generally vary from 0.5 HP (350 watts) to 2 HP (1500 watts) devices. Running a 1 HP blower (750 watts) overnight for eight hours uses about 6 kWh. At a national average of 15 cents per kWh, this totals roughly $0.90 per night.
Commercial restorations with multiple blowers can increase costs, but prompt drying prevents expensive repairs from mold and structural damage, making this investment worthwhile.
Mold, Mildew, And Indoor Air Quality
Continuous drying with a carpet blower is one of the best defenses against mold and mildew after water exposure. Moisture trapped in padding or subflooring becomes a breeding ground for spores within 24 to 48 hours.
If chemicals or biocides are used after water extraction, ensure the blower is strong enough to ventilate lingering fumes, enhancing indoor air safety. Adding an air purifier or HEPA filter can further improve results in sensitive settings.
Signs Your Carpet Blower Should Not Be Left On Overnight
