Cottonwood Air Quality Impact: How PreVent® Prefilters Shield Rural Spaces

The Cottonwood Challenge

As the cottonwood season approaches, building managers face a persistent annoyance—the constant influx of cottonwood seedlings. These seemingly innocuous fluff particles, measuring just 1/10 of an inch, can wreak havoc when they infiltrate rooftop HVAC systems. Here’s why cottonwood poses a challenge:

1. Clogging and Reduced Performance: Cottonwood seedlings easily clog HVAC filters and cooling fins. Reduced airflow affects system efficiency, impacting air quality within factories and facilities.

2. Worker Health and Productivity: When thousands of cottonwood seedlings descend upon a facility, air quality suffers. Workers exposed to poor air quality may experience respiratory issues, allergies, headaches, and fatigue.

3. Humidity and Temperature Regulation: Blocked airflow disrupts precise humidity and temperature control, leading to production inefficiencies and higher costs.

PreVent®: The Solution

PreVent® prefilters emerge as the ultimate defense against cottonwood and other airborne pollutants. Here’s why they stand out:

1. Improved Performance:

   • Designed for first-line particle filtration, PreVent® prefilters surpass traditional mesh filters.
   • Their smooth fiber fabric minimizes airflow resistance while maximizing debris-holding capacity.

2. Cost Savings:

   • Washable PreVent® prefilters offer cost-effective solutions.
   • Models like PreVent Model PF slide into existing filter systems, reducing the need for disposable filter change-outs.

3. Versatility:

   • PreVent® offers various mounting options and frames, tailored to specific needs.
   • Consider adding a vinyl-framed prefilter screen in front of pleats to capture large particles.
