Learn how Vornado's Energy Smart Air Purifier combines Silverscreen technology with True HEPA filtration to capture particles and destroy molecules that HEPA alone can't handle.
Quick answer
The Vornado Energy Smart Air Purifier (PCO575DC) pairs True HEPA filtration with Silverscreen technology to capture airborne particles and chemically destroy molecules that HEPA cannot trap, such as odors and volatile organic compounds.
Why HEPA alone isn't enough
True HEPA filters remove up to 99.97% of particles as small as 0.3 microns, including dust, pollen, and mold spores. However, gases, odors, and some chemical vapors are smaller than 0.3 microns and pass through HEPA media. That's where the additional technology comes in.
What Silverscreen adds
Silverscreen is an enhanced catalytic oxidation process that uses UV light and a specialized coating to create reactive species that destroy volatile organic compounds (VOCs), odors, and other gaseous pollutants. It does not replace the HEPA filter but works after it to address what HEPA misses.
FAQ: Silverscreen and HEPA in the Energy Smart Air Purifier
- Does Silverscreen replace the HEPA filter?
- No. Silverscreen works alongside the True HEPA filter. The HEPA filter captures particles; Silverscreen destroys gaseous pollutants that pass through the HEPA media. Both are needed for comprehensive air cleaning.
- How often should I replace the HEPA filter in the PCO575DC?
- Vornado recommends replacing the True HEPA filter every 12 months under normal use. The Silverscreen module has a longer lifespan and typically lasts 1-2 years before needing replacement. Check your unit's filter indicator light for specific timing. Set a calendar reminder at 11 months to check the filter status.
- What types of pollutants does Silverscreen destroy?
- Silverscreen targets volatile organic compounds (VOCs) from paints, cleaning products, and cooking, as well as odors from smoke, pets, and cooking. It also helps neutralize certain bacteria and viruses that HEPA filtration alone cannot eliminate.
- Can I run the Energy Smart Air Purifier continuously?
- Yes. The Energy Smart feature automatically adjusts fan speed based on air quality, so the unit runs efficiently without wasting power. Continuous operation is safe and recommended for maintaining clean air. Let the purifier run 24/7 on Auto mode for best results.
Product facts
- PCO575DC Energy Smart Air Purifier with Silverscreen® and HEPA Filtration: The PCO575DC combines True HEPA filtration (removes 99.97% of airborne allergens down to 0.3 microns) with an Advanced Carbon Filter and Silverscreen technology. This three-stage approach captures particles, adsorbs odors and gases, and destroys chemical molecules that a HEPA-only purifier would leave in the air.
