Air Quality Awareness Week – How Electrostatic Filters Work and How They Can Benefit Indoor Air Quality
Did you know indoor air can be more polluted than outdoor air? This Air Quality Awareness Week, discover how electrostatic filters are revolutionising air filtration by achieving higher efficiency and lower pressure drop. This leads to cleaner air, lower energy costs, and a reduced carbon footprint.
As US Environmental Protection Agency (EPA) Air Quality Awareness Week reminds us, indoor air quality is crucial to our health. At Techtextil North America, filtration professionals are exploring innovative solutions to address growing demands for performance and sustainability. Electrostatic filters are at the forefront, offering energy-efficient filtration that captures dust, allergens, and pollutants, maintaining low pressure drop and extending filter life.
Types of Electrostatic Filters
– Ionising Filters: Charges airborne particles and attracts them to oppositely charged plates. Effective for large particles but may generate ozone.
– Polarised Filters: Induces charges within the filter media so particles clump together and are more easily captured. Often ozone-free.
– Electret Filters (like meltblown): Uses permanently charged fibres to capture fine particles. Efficient and low-resistance.
– Triboelectric Filters (like Lanaco’s EcoStatic®): Generates natural electrostatic charge from fibre friction. No chemicals or artificial charging methods required.
The EcoStatic® Advantage
At Lanaco, performance comes first. EcoStatic® is our high-performance, electrostatic filter media made using New Zealand wool and proprietary technology to enhance its natural triboelectric properties. This means you get:
– High Efficiency: Captures fine particles including dust, bacteria, and viruses for cleaner indoor air.
– Low Pressure Drop: Better airflow and energy savings while maintaining strong filtration performance.
– Sustainable Credentials: Renewable, biodegradable, PFAS- and formaldehyde-free, and USDA Certified Biobased.
– Proven Track Record: Trusted in mission-critical applications, including NASA – National Aeronautics and Space Administration’s Artemis space missions.
– Natural Benefits: Wool is naturally hydrophobic and fire-resistant – no added treatments necessary.
– Game-Changing Innovation: Our EML series is a future-ready 100% biobased, patent-pending breakthrough for manufacturers seeking performance without compromising sustainability.
Choosing the Right Filter
There’s no one-size-fits-all answer. Filtration professionals should consider the pollutants to remove, system airflow, regulatory requirements, MERV rating, and sustainability targets. At Lanaco, we help industry leaders and engineers navigate these choices confidently. If you are seeking a performance-driven, sustainable solution, EcoStatic® stands out for its efficiency and can directly reduce your carbon footprint.
