Precise Air Quality

HEPA Where You Need It

Alen HEPA purification systems provide targeted, room-level air cleaning that continuously removes airborne particles from busy spaces. This adds an extra layer of protection where students and staff spend the most time.

Keep students and staff safe.

HEPA air purifiers reduce exposure to airborne particles like allergens, viruses, and pollutants, helping create a healthier environment for students and staff. By continuously removing fine particles at the source, they support better focus, reduce absenteeism, and create a more comfortable environment throughout the day.

Protect your wallet.

Supplementing with HEPA air purifiers reduces the particle load on HVAC systems, helping filters last longer and maintaining proper airflow without added strain. This lowers maintenance frequency, protects equipment over time, and helps districts save money.

Alen HEPA filters can capture 99.9% of particles down to 0.1 microns.

Filters Engineered for Excellence

Alen purifiers use a multi-layer system to clean air efficiently. A pre-filter captures larger particles like dust and hair, while the HEPA layer removes fine particles such as pollen, mold, bacteria, and even ultrafine pollutants.

For models with activated carbon, an additional layer targets odors, smoke, and VOCs. Together, these layers continuously cycle and clean the air, delivering fresher, healthier indoor environments.

HEPA Air Purifiers for Healthier Classrooms

The CDC advises using air purifiers with HEPA filters in classrooms to help reduce airborne virus particles.

Alen air purifiers use HEPA filtration to capture 99.9% of particles as small as 0.1 microns, helping meet recommended air changes per hour and reducing triggers for illness, allergies, and asthma.

From allergens and mold to smoke and pathogens, high-capacity filtration keeps indoor air cleaner, supporting fewer absences, better concentration, and a safer learning environment for both students and teachers.

Prepare for Wildfire Season

Wildfire season can quickly impact indoor air quality, even miles from active fires. HEPA air purifiers help protect classrooms by continuously capturing fine smoke particles (PM2.5) that HVAC systems often struggle to remove on their own.

Paired with an advanced filter like Alen’s Ultimate Filter, which uses a proprietary carbon catalyst blend, purifiers can also help reduce smoke odors and harmful gases. This added layer of protection helps schools maintain safer, more stable indoor air conditions when outdoor air quality becomes unpredictable.

Increase Funding with Alen

Increase Average Daily Attendance (ADA)

Chronic student absences result in significant funding losses for school districts each year. Alen classroom air purifiers can help you increase ADA and reach your annual funding goals.

Full payback in six months or less

The projected increase in ADA will generate enough additional revenue to recover the cost of your Alen air purifiers in six months or less.

Alen's Forever Guarantee

With regular filter replacement, all Alen air purifiers are guaranteed for life. That means if you have an issue with one of our purifiers, we'll fix it or replace it for free.

Schools Who Trust Alen

Alen® air purifiers are currently in 90,000 classrooms across 3,000 schools.

Reduce Airborne Exposure

The Alen Partnership Program uses high capacity medical-grade HEPA filtration. By continuously removing fine particles from the air, organizations can reduce airborne exposure risks and support healthier spaces for everyone.

Streamline Operations

Easily manage devices and filter maintenance through a centralized system. Teams can track performance, schedule filter changes, and maintain reliable air purification without complicated workflows or manual oversight.

Simplify Procurement

Find budget efficiencies with an easy procurement process, reduce costs with fewer changeouts, and improve efficiency with better data.

Proactive Health Leadership

Move from reactive air management to proactive health leadership. Air quality monitoring (AQM), airID technology, and environmental sensors provide real-time awareness of indoor air conditions. Insights that allow you to identify issues early and optimize air performance.
