COVID-19 & VIRUS Air Filtration: 1 - Stand-Alone Systems

1. What is Covid 19?
Answer: Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.

2. What are the Covid-19 health concerns around aerosol spread?
Answer: Scientists and researchers are continually gathering new evidence about this disease, including routes of transmission. New data suggests that it is possible for COVID-19 to spread through the air among people who are in enclosed, crowded spaces with poor ventilation for a prolonged period of time. Factors contributing to the transmission may include activities that cause heavy breathing, such as singing, dancing or exercise, especially without precautions such as wearing a mask or keeping a physical distance. However, close, person-to-person contact with an infected person before they show symptoms remains the most common method of transmission.

3. Can mechanical air filtration systems make indoor spaces safe from Covid-19?
ANSWER: If you are in a room that can’t get enough outside air for dilution, consider an air cleaner, also commonly called air purifiers. These machines remove particles from the air, usually using a filter made of tightly woven fibers. They can capture particles containing bacteria and viruses and can help reduce disease transmission.

The U.S. Environmental Protection Agency says that air cleaners can do this for the coronavirus, but not all air cleaners are equal. Before you go out and buy one, there are few things to keep in mind.

In light of the WHO's confirmation that there is "emerging evidence" of airborne transmission of Coronavirus Lev-co has put together a series of products that may assist you in designing and procuring solutions that limit the spread of airborne particles such as the coronavirus. In this section you will find equipment that addresses each of these components required in a ventilation system tailored to capture and filter and return air to your facility:

4. What do the health experts say?
ANSWER: the EPA says: " When used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from exposure to the virus that causes COVID-19. When used along with other best practices recommended by CDC and others, filtration can be part of a plan to reduce the potential for airborne transmission of COVID-19 indoors."

5. How do different systems work and what are the practical and health concerns?
ANSWER: See our list of Control measures listed below, Please note, the practical and health concerns are listed within each CM:

5.5 What are the common components of a Covid-19 Ventilation system
ANSWER: See Below:

  • Supply Air diffusers and/or Nozzles to direct the clean air to the occupant
  • Transport ducts and hoses
  • Powered and non-powered filter housings and air cleaners
  • Electrical controls (VFD and differential Pressure controls
  • Booster fans (Optional)
  • Capture devices

6. In what kind of environments can mechanical air filtration systems be most effective?
ANSWER: the environments that are best suited for mechanical ventilation are:

  • Nursing homes
  • Fitness clubs
  • Restaurants and bars
  • Meeting rooms
  • Lunchrooms and cafeterias

Here is an article from the CDC discussing this further: https://www.cdc.gov/niosh/docs/2003-136/pdfs/2003-136.pdf

What are the pros and cons of Local Exhaust Ventilation versus HVAC solutions? Are there any other possible solutions?
ANSWER: Local Exhaust Ventilation is best suited to the control and filtration of the covid virus because it controls the virus at source and directs the virus aerosol to the filter unit, typically before it can be inhaled by another person where HVAC simply mixes or dilutes the contaminated air allowing other persons to breathe the air in before the air is filtered from the virus.

(20-011) ICA ''Over Table Hood''
with H14 Filtration

- For Meeting, Lunch, Coffee Rooms and Benches
ICA-clean-to-less-clean-h14-hepa-filter-system-for-respirable-viruses-in-meeting-and-lunch-rooms - Main Image

LEV-CO’s Stand-alone ICA (Immediate Clean Air) “2-Zone Air Defence” for Coffeerooms, Lunchrooms, Meeting rooms. and benches. A simple “Pre-engineered” solution with "Clean-to-less-clean" air distribution, HEPA H14 Filtration (99.995% @ 100 Nanometer), Duct and Diffusion Hood.



The ICA hoods are available in four lengths: 1m (2-4 people), 1.5m (4-6 people), 2m (6-8 people), and 2.5m (8-10 people).

Clean Filtered Air leaves the diffusion hood and reaches the table (roughly 1 meter below) after 1.31 seconds after the Air Purifier module is turned on!

The ICA ventilation systems have been designed to control, capture, filter and return contaminated air in various workplaces.

This solution employs the ventilation method of "Clean-to-less-clean" air movement coupled with HEPA filtration as recommended by the CDC, ASHRAE, WHO and more. By using this system you will immediately achieve 99.995% clean Air around the Table and after a short While a 98-99% Reduction of the Virus and Bacteria in the rest of the Room.

NEW GUIDANCE FROM CDC, ASHRAE, AND WHO, REGARDING 'CLEAN-TO-LESS-CLEAN AIR MOVEMENT':

Extracted from ASHRAE's Technical Resources for Healthcare Web Page
Airflow from Clean to Less Clean
  • More important than having to wait a longer time between room changeover due to lower ACH
  • More important than air change rate
  • More important than outside air % above 2ACH


By just having a normal conversation, aerosolized virus and bacteria can remain in the air indefinitely, therefore it is important to use forced air to direct these aerosols away from the occupants and allow them to be captured by the HEPA H14 fan/filter unit where the air can be filtered and returned to the space. This limits the transmission of respirable viruses such as Influenza, Coronavirus, common cold, etc. thus substantially reducing the risk of being infected. For example; the zone over and around a 6-person table is approximately 10m3. This gives you a total ACH (Air Changes Per HOUR of 60 ICA-700 filters.

This solution has a typical payback of 1 year when compared to the costs of 1-week sick leave, per year, per employee.

The systems use a combination of clean-to-less-clean air movement, HEPA Filtration and optional UV light as recommended by both the CDC and ASHRAE. The cleaned air is supplied at a rate of 700 M3/H (400 CFM) or 1000 M3/H (600 CFM) per filter module, directly to the occupants breathing zone. This creates a "Bubble" of constantly filtered clean air around the table and up to 53 air changes in the room.*

Here's how it works:
  • STEP 1: The "Clean-to-less-clean" air movement supplies clean filtered air to the occupants breathing zone through a pre-engineered diffusion hood explicitly designed for the application e.g., meeting rooms, lunchrooms, Locker rooms, classrooms, etc. This precise air movement is essential as the viral particles associated with Covid-19 have shown that they can remain airborne, for up to 16 hours in still air.
  • STEP 2: An ultra-low noise fan draws the room air in at floor level where the air is least clean. The air is drawn in by a variable speed, centrifugal fan that allows the operator to control the flow based on the number of people in the room.
  • STEP 3: The air passes through a silenced chamber engineered to dampen the associated noise generated by the air movement.
  • STEP 4: A multi-stage filter module filters the contaminated air containing virus particles as small as 0.1 Micron (MicroMeters) to a purity level of 99.995%.
  • STEP 5: An optional UVC germicidal treatment lamp can be purchased as a supplement to help destroy virus particles that may remain attached to the inner surfaces of the unit’s air intake housing.
  • STEP 6: Clean filtered air is returned to the indoor space through a low-noise duct and diffuser hood detailed in Step 1, thus completing the filtration and ventilation circuit. This allows the air in a typical room to be changed over 100 times an hour.

t140-ducted-air-cleaner-self-cleaning-filters - Main Image
3600-4500 CFM "Free-Hanging" T-STYLE air cleaner complete with an integrated Blower and filter system.

Ideal for "Cross-Dilution" and filtration of airborne pollutants that can't be easily captured at source. The T-STYLE configuration allows the contaminated air to enter from both ends of the unit and the cleaned air to exit from the center of the housing. This allows the air to be filtered by twice the media resulting in a much lower "AIR-TO-CLOTH" ratio which in turn means greater filter life, quite often 2 to 4 times the average filter life of that of a regular uni-directional "Flow-Through" filter system. The center exhaust also allows for better dilution of the contaminated air, and in the case of large plants, it has an added energy saving effect. Latent heat, high up in the plant is de-stratified when the exhaust vents are directed upwards, towards the center of the ceiling. This results in not only a much more comfortable working environment, but also has a sizable energy saving effect through a better distribution of the conditioned air throughout the building. Each "Free-Hanging" (also called "Packaged"), air cleaner comes complete with 65% eff.. filters, Direct drive blower, 208,230,460,575V/3/60 TEFC, 2 HP motor, Single speed motor. Unit comes standard in a blue baked-on powder coated finish.

(20-021) Mobi-Dental Extraction at Source - Portable H14 Filtration (600 CFM) **
Mobi-oil is an easy to use, portable filter that extracts oil & coolant mist from lathes, milling machines, drill presses and other similar processes.

Mobi-oil is an easy to use, portable filter that extracts oil & coolant mist from lathes, milling machines, drill presses and other similar processes. This filter comes complete with a self-supporting extraction arm (7’ or 10’) with a simple to position extraction hood that allows the collection and filtration of mists and liquids, “at-source” before they have a chance to escape into the work place. The collected contaminants are filtered by a series of specifically designed filters that allow the cleaned air to be returned back to the facility and the mist & liquids to drain into one (1) of two plastic containers. The collected liquids can then be reused in the machining process.
