Tabletop Disinfection for Dining

Dining typically involves opening your mouth, unless you need to eat from a straw, which is an added problem beyond COVID-19. It’s hard to wear a mask and social distance when eating at a restaurant, school, or an event such as a wedding. Laughing, sneezing, or even breathing can spread COVID-19 to fellow diners at your table or adjacent tables. This is particularly the case with people that are asymptomatic. This makes “dining” an activity that warrants ACUTE disinfection.

This disinfection device solution was initially developed for countertops and wall mounting, both of which are typically near wall outlets. This tabletop disinfection solution incorporates a rechargeable battery.

Dining impact of COVID-19:

According to the CDC Report on September 11, 2020, “Adults with positive SARS-CoV-2 test results were approximately twice as likely to have reported dining at a restaurant than were those with negative SARS-CoV-2 test results.” Full Report

The New York Times reported on April 20, 2020, “In January, at a restaurant in Guangzhou, China, one diner infected with the novel coronavirus but not yet feeling sick appeared to have spread the disease to nine other people. One of the restaurant’s air-conditioners apparently blew the virus particles around the dining room.” Full Article

SOLUTION: Portable tabletop disinfection that integrates ultraviolet (UVC) light with photoplasma to purge COVID-19 in seconds not minutes. It is less than 12” across and less than 9” tall, so it does not block conversations across tables.  To learn more, see the third-party Test Report information from December 2020, the Disinfection Device Video, and the Specification Sheet.


If you do not have a battery for the table, we have done the research and found that GOAL ZERO has a rechargeable one that works well.  Order the battery here.

If you would like to put a “top” across a pair of the devices for tables that seat more than 4 people, we have found that home improvement stores (e.g. Home Depot) and craft supply stores (e.g. Michael’s) have many great choices that range from 12″ x 12″ to larger sizes in wood, tile, stone, plexiglass, etc.

These tabletop disinfection layouts include the dual device combined with the battery given that many dining tables do not have easy access to electricity wall sockets. Single devices work well up against the wall for restaurant booths or tables that are set against walls with close proximity to wall outlets.

Sample Restaurant with wall outlets:

restaurant disinfection

For facilities with average air circulation of 4 air changes per hour (AHC), the PR30 devices covers up to 415 square feet. This is particularly relevant for restaurants that are may have about 1,600 sq ft of dining areas. 4 devices will disinfect the air across the tables that are near the placement of the device. This floor plan below illustrates a situation where the wall outlets reduce the need for the tabletop disinfection combination with the batteries. In this example of a Quick Serve Restaurant (QSR), an added device is mounted on the wall near the Ordering Area, to further protect customers and the staff. The overlapping purple circles represent the overlap of coverage are for Ordering Area and the tables that are in the center of the restaurant.

Tabletop Disinfection PATENT: Our patent submission with the U.S. Patent and Trademark Office (USPTO) on October 15, 2020 is still pending and under development to integrate the battery with the most appropriate disinfection technology. This combination of existing technology and the battery is a bridge to future tabletop disinfection devices. As battery technology improves, we also hope to reduce the overall size of the combined solution. Given that COVID-19 persists, we recommend using the combination during the pandemic.

The cost of each disinfection device is $450 and the battery is $200 for a total of $650 per table. If you choose the dual disinfection, then the total technology cost increases to $1,100 per table. There are rechargeable batteries on the market other than the one referenced here, but be sure to check the wattage capacity and amperage to ensure adequate power and longevity between nightly charging.
