The Discharge Myth: Why Most Electrostatic Filters Are Built to Fail
In the air filtration world, we’re told that electrostatic filters are unreliable because they lose their charge. The ISO 16890 standard even requires a discharged efficiency rating to show how a filter performs once that static “magic” wears off.
But here’s the truth: most synthetic filters do fail because they rely on a fragile, surface-level charge that vanishes the moment it hits humidity or oily particles.
For those filters, ISO 16890 isn’t a safety check, it’s a countdown to failure.
Enter Lanaco’s EcoStatic®: The technology that refuses to play the discharge game.
Unlike synthetic meltblown or nanofiber media that bleed charge, EcoStatic® uses the natural, evolutionary properties of New Zealand wool to create a permanent triboelectric charge.
Here is why the red herring shouldn’t apply to us:
• Charge that Sticks: Because EcoStatic® is a needlepunched triboelectric nonwoven made with natural wool, the charge is structural, not just a surface treatment. It doesn’t just “wash away.”
• Water Resistance is Built-In: While humidity kills the charge in synthetic filters, EcoStatic® is naturally superhydrophobic. It was selected by NASA for the Artemis missions specifically because it maintains high efficiency in wet and extreme environments where others “discharge” and die.
• Beyond Particle Trapping: Most filters stop at dust. EcoStatic® uses its natural chemical structure to neutralize VOCs like formaldehyde and ammonia while maintaining its filtration integrity.
• The “MERV 13 for MERV 11 Resistance” Advantage: We deliver premium protection with ultra-low pressure drop, meaning you get the efficiency without the energy-sucking “choke” on your HVAC system.
Stop settling for filters that need a “discharged” rating just to manage expectations of their inevitable failure.
Choose the media that was built to stay charged, stay efficient, and stay natural.
