A coronavirus air filtration system that actually works

The BlueSky® Defender is a ducted, coronavirus HEPA air filtration system that generates twelve to fifteen whole-room air-exchanges per hour.

It creates a top-to-bottom, laminar airflow that removes the aerosols emitted by people present.

Ductless air filtration doesn't work because it relies on air dilution. HVAC systems don't support HEPA.

A ducted HEPA air filtration system that significantly reduces the risk of spreading coronavirus (COVID-19) in indoor spaces

Deploying a BlueSky® Defender coronavirus air filtration system* in public places to help reduce the spread of the coronavirus (COVID-19) makes sense. For government facilities, supermarkets, drug stores, government, and other places that need to stay open. BlueSky offers HEPA air filtration systems* designed to handle up to 25,000 SCFM of contaminated air per machine.

The BlueSky® Defender line-up

BlueSky® Coronavirus Defender machines come in four standard sizes.

Defender 10        up to         600 SFT

Defender 25        up to      1.600 SFT

Defender 50        up to      4,000 SFT

Defender 100      up to    10,000 SFT

>10,000 SFT use multiple Defender units

Which model works best in any given space is dependent on the size of the interior space being serviced and how many air-changes are required. For high-occupancy areas or vulnerable locations, 12 room air-changes per hour is recommended.

The physical placement for a BlueSky® Defender air filtration machine can be interior or exterior.

Ducted coronavirus air filtration system

There are many different air-cleaning machines, air filtration systems, and air purifiers on the market. Some use ultraviolet light, others use electrostatic filters. Most air filtration systems and purifiers rely on a combination of these technologies

What these in-room machines have in common is they are stand-alone in-room machines that are not ducted. They don't create a laminar downflow of clean air.

All these technologies clean air through the principle of dilution. Being in a space with such a machine means breathing in air that is always partially contaminated.

Air exchange through laminar downflow

The BlueSky® Defender coronavirus air filtration system creates a top-to-bottom laminar airflow that constantly removes aerosols emitted by people present in an indoor space. HEPA-filtered and UVC disinfected, air moves down continuously from vents above, while potentially contaminated air is sucked down-and-out through vents below, preventing aerosols from lingering and spreading. 

Safe, no-touch, filter change-out module

A significant benefit of the BlueSky® Defender is that, unlike all other machines, the used (contaminated) filters in a BlueSky® machine are never touched by local service personnel. They are safely sealed inside the SmartBox® module.

The BlueSky® SmartBox® system eliminates the risks associated with the handling of contaminated filters

The patented BlueSky® SmartBox® is an integral part of the BlueSky® Defender coronavirus air filtration machine. All other HEPA air filtration systems (coronavirus-specific, or otherwise), require manual handling of potentially contaminated filters.

Coronavirus air filtration system for indoor movie sets, sound stages and broadcast studios

Work on movie sets, sound stages and in broadcast studios, present special challenges during the coronavirus pandemic. PPE (masks, gloves, etc.) won’t work for obvious reasons.

Stand-alone, in-room, HEPA filtration systems and air purifiers are inadequate even under ideal circumstances. For large indoor spaces, especially broadcast studios and sound stages, diluting the contaminated air simply won't do. A laminar downflow system, like the BlueSky® Defender air filtration system, is the only available solution that actually works.


The BlueSky® Defender air filtration system creates a top-to-bottom laminar airflow. Aerosols emmited by people present are moved down immediately after leaving a persons nose or mouth, not giving them a chance to linger

UV-C light disinfection

In addition to utilizing HEPA filtration to catch coronavirus (COVID-19) and other pathogens, the BlueSky Dender air cleaning systems are also equipped with high output UV-C lamps* (one per filter cartridge) that sterilize the filter fabric continuously.

Ultraviolet (UV) light is produced by the sun and by special lamps. There are three types of UV light—UVA, UVB, and UVC. UVC light has the most energy of the three types. This energy destroys the genetic material inside viruses and other microbes. Therefore, UVC light is used for disinfection. UVC lamps are commonly used to sanitize water, objects such as laboratory equipment, and spaces such as buses and airplanes.

The blue ducts push down the clean HEPA filtered air. Potentially contaminated air is sucked out via vents in the purple ducting near the floor—from where it is then pumped through the BlueSky® DEFENDER air filtration machine to be de-contaminated.
