COVID-19 – A Global Emergency

Stop the spread of COVID-19 with Better Indoors air disinfection technology

We are all focused on taking steps to prevent the spread of the coronavirus that causes the COVID-19 disease by wearing masks, washing hands and cleaning/disinfecting surfaces. Some of us are taking steps to improve ventilation and/or using air purifiers. However, none of these actions will stop it from being transmitted from person to person when we breathe, talk, cough, sneeze or when we touch an already infected surface. Remember surfaces can be immediately recontaminated after disinfection. 


Better Indoors air purifier and air disinfection products offer a unique solution. Our patented technology continuously and safely disinfects all of the air and surfaces in an indoor space and instantly destroys viruses the moment they are exposed before they can be transferred to others. This adds a new and unique dimension to your household or office cleaning regime. Our air purifier products also eliminate odours and purify the air of bacteria, mould spores, VOCs and particulates including pollens, house dust, traffic soot and smoke.


Our technology is used all around the world in homes, offices, schools, hospitals, dental/GP offices, care homes, gyms, public buildings, cars, airliners, ships, public transport, food processing plants, warehouses etc. It is completely safe for humans unlike passive ozone generators such as Biozone Airsteril which are dangerous. Shockingly these units are sold by firms like Rentokil Initial and PHS and are used in the WCs of known entities such as McDonalds, London City Hall and Tf which illustrates how far the UK is behind the curve in terms of public knowledge in this area and of indoor air quality standards and regulations. In 2003 our technology was selected by the Chinese government during the SARS outbreak for infection control in public buildings and on public transport and right now urgent shipments are underway to help combat COVID-19.

Independent confirmation the Wuhan coronavirus can survive in aerosols for 3 hours


A comparison of durability and survivability between the SARS (SARS-CoV-1) and Wuhan (SARS-CoV-2) coronaviruses was conducted in 5 mediums – aerosols, plastic, stainless steel, copper, and cardboard. The results were similar for both pathogens. When transmitted in aerosols both viruses remained viable after 3 hours and can remain on surfaces for up to 9 days with the longest survivability on stainless steel and plastic. Contributors to this research wrote a letter to the New England Journal of Medicine which published their findings on 17 March 2020. Click here to read the report.

Independent corroboration of Photohydroionisation core technology


An analysis of 22 studies reveals that human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently deactivated by surface disinfection procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute.


Our products produce a “Photohydroionisation or PHI” plasma comprised of hydro-peroxides, ionised hydroxide ions and super oxide ions in safe concentrations not exceeding 0.02 ppm – similar to the concentrations found in the atmosphere (0.01-0.03 ppm).This is the heart of the art protected by the patents as all other active products produce oxidisers that are dangerous or rely on dangerous UV-C light. The US, EU and UK STEL (8 hour) limits for hydro-peroxides are between 1 and 2 ppm so these concentrations are a tiny fraction of these. The plasma is distributed throughout the entire indoor space and break down and destroy organics including human coronaviruses on contact through the process of cell lysing – the same process that all surface disinfectants like Dettol rely on. Please note at concentrations of 0.01ppm there are approximately 177,000,000,000,000,000 (quadrillion) hydro-peroxide gas molecules in a single litre of air, which means they are close to one micron apart. So, bacteria, odours, viruses, VOCs, moulds etc. do not have to move far to be hit with one and destroyed. The US EPA recognises hydro-peroxide gas at concentrations of 0.01 ppm as an effective infection transmission control and microbial treatment technology.


PHI technology has been successfully tested on pathogens and contaminants in the air and on surfaces as the lab test results on the website show ( This is important because deadly pathogens like Norwalk, SARS, MERS, Novel Coronavirus can be transferred to surfaces by touch where they can survive for up to 9 days. The plasma molecules settle on surfaces and kill these deadly pathogens on contact. 


The sneeze test proved its uniquely capability to stop airborne infection transmission by killing 99% of all germs emitted from the test subject and travelling at over 100mph before they had travelled 3 feet. This is how our products will prevent the spread of the virus that causes COVID-19. No passive air purification technology or cleaning regime can do this.



PHI technology is completely safe for humans in any indoor setting – domestic, commercial, transport etc and has absolutely no detrimental effect on the human immune system. There has never been a safety issues in over 4 million installations in over 60 countries.


PHI technology has been extensively employed by the food processing industry for many years. Numerous medical facilities have embraced it to reduce rates of deadly pathogens including H1N1, SARS, C-Diff (9) (11), MRSA, etc. Schools use it as it reduces absenteeism of students and teachers. It has been tested and approved by the US Military and the US Homeland Security. It is also used all over the world in homes and offices, hotel rooms, gyms, restaurants, cars, trains, planes, cruise ships, medical facilities, care homes, doctor and dentist waiting areas, hospitals, public buildings, libraries. In fact any indoor space where humans congregate will benefit from PHI. Units can be integrated into existing HVAC systems/duct infrastructure or installed standalone depending on the HVAC strategy and occupancy size/type.

CIBSE COVID-19 Guidance: Emerging from Lockdown


Safely re-occupying buildings


As businesses start to consider bringing staff back into work premises, a number of issues need to be considered for the safety of everyone entering the building. Government guidelines should be followed.


This brief document entitled CIBSE COVID-19 Emerging from Lockdown: Safety Reoccupying Buildings is intended to give business owners, managers and employers an outline of the main areas that need to be considered concerning both safe working practices and the assessment of building services. It includes links to a new Health and Safety Executive (HSE) website on minimising the risk of legionella.


Ventilation guidance

The advice in this document entitled CIBSE COVID-19 Ventilation Guidance is for building owners/managers and operators when reopening buildings following a period of inactivity and considering the requirements for the ventilation system.
