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 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. 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 TfL 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.
Click here and complete the form or call 0333 014 7669 or email firstname.lastname@example.org for information on unit sizing, costs and delivery timescales. Installation is quick and simple. The units have no moving parts and just need to be positioned and turned on.
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.
REME and PHI are similar air purification technologies. REME is more advanced with added capabilities in the area of particulate removal. Both produce a 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.
REME & PHI have been successfully tested on pathogens and contaminants in the air and on surfaces as the lab test results on the website show (https://rgf.com/test-results/). 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.
REME & PHI technologies are completely safe for humans in any indoor setting – domestic, commercial, transport etc and have absolutely no detrimental effect on the human immune system. There have never been any safety issues in over 4 million installations in over 60 countries.
REME & PHI technologies have been extensively employed by the food processing industry for many years. Numerous medical facilities have embraced them to reduce rates of deadly pathogens including H1N1, SARS, C-Diff (9) (11), MRSA, etc. Schools use them as they reduce absenteeism of students and teachers. They have been tested and approved by the US Military and the US Homeland Security. They are 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 REME and/or PHI. Units can be integrated into existing HVAC systems/duct infrastructure or installed standalone depending on the HVAC strategy and occupancy size/type.

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.
Better Indoors has argued since the start of the pandemic that the COVID-19 coronavirus is transmitted via airborne routes. Click here to read our various letters to UK Prime Minister The Rt. Hon. Boris Johnson MP dated 27 March 2020, 27 April 2020, 12 August 2020, 27 September 2020 and 21 November 2021 affirming aerosol and surface transmission of the coronavirus, explaining the differences between the technologies, describing some of our customer success stories and offering our help and assistance. Click here to read the text of a letter sent to Fraser Nelson, editor of The Spectator on 15 Oct 2020 criticising aspects of COVID-19 mitigation guidance and describing REME technology as the most effective solution for indoor spaces.
Click here to read “It Is Time To Address Airborne Transmission of Covid-19” open letter from 239 scientist signatories to World Health Organisation published on 6 July 2020 affirming aerosol transmission of SARS-CoV-2 and asking WHO to address the issue in guidance in context if increasing global infections following relaxing of lockdowns around the world.
The Centers for Disease Control and Prevention (CDC) in the US first published information about airborne transmission on its website on Friday 18th Sep 2020. It said COVID-19 could be spread through “respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes. These particles can be inhaled into the nose, mouth, airways and lungs and cause infection. This is thought to be the main way the virus spreads”. It then removed the information on Monday 21 Sep 2020 saying it had been published “in error”.
It then updated its guidance on 5 October 2020 to say “Today’s update acknowledges the existence of some published reports showing limited, uncommon circumstances where people with COVID-19 infected others who were more than 6 feet away or shortly after the COVID-19-positive person left an area. In these instances, transmission occurred in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise. Such environments and activities may contribute to the buildup of virus-carrying particles.”
CDC’s latest guidance is also clear about asymptomatic transmission. It says “People who are infected but do not show symptoms can also spread the virus to others”. It also says COVID-19 spreads “less commonly” through contact with contaminated surfaces and “rarely” between people and animals. Further, CDC says people can protect themselves from the coronavirus by staying 6 feet away from others, by wearing a mask that covers the nose and mouth, washing hands frequently, cleaning surfaces and staying at home when sick.
Strong evidence of airborne dispersal is presented in this study by a team from Uppsala University Hospital in Sweden. Performed during April and May 2020 the team examined the ventilation systems including grilles, HEPA filters and ductwork in a number of wards for evidence of SARS-CoV-2 and found it’s genes in all locations. The study concluded preventative measures must take airborne transmission into consideration.
SAGE provides scientific and technical advice to support government decision makers during emergencies and is responsible for ensuring that timely and coordinated scientific advice is made available to decision makers to support UK cross-government decisions in the Cabinet Office Briefing Room (COBR).
Since the pandemic hit SAGE has published various advisory documents relating to COVID-19.
On 23 October 2020 SAGE Environmental Modelling Group published its paper “Role of Ventilation in Controlling SARS-CoV-2 Transmission” (click to review). The document discusses the importance of ventilation as a mitigation strategy in both new and existing buildings for “far-field aerosol airborne transmission and suggests some methods for improvements. It also mentions some of the drawbacks that should be avoided such as impacts on thermal comfort, health and energy efficiency especially during winter and that ventilation improvements have no effect on surface transmissions. It also states “Research on real-world application of air cleaning and filtration technologies and development of guidance on best practice is urgently needed in order to determine those which are safe and effective” which illustrates the lack of awareness by SAGE of two key approaches that are already considered best practice by some in the UK:
1. Whole building background ventilation improvements that are economical and can be easily specified and retrofitted by suitably qualified industry professionals. The strategy of Positive Input Ventilation referred to in Part F using products that hold the requisite performance and compliance certifications are effective and proven to increase background dilution/displacement ventilation throughout an entire property and are used to routinely used to solve problems of excess humidity (condensation, mould) and indoor air quality problems including airborne allergens, odours, VOCs, radon and other gases and pollutants.
2. There are active air purification technologies (REME and PHI) from RGF Environmental Inc (www.rgf.com) who is recognised as the world’s leading innovator in environmental air and water purification and food safety whose technologies have been in production for over 15 years, are installed in millions of standalone and in-duct products across a wide range of sectors (including food processing) in many countries around the world and have been independently tested for safety and efficacy across all three main categories of IAQ pollutants (microbials including SARS-CoV-2, gases and particulates) by various nationally accredited laboratories and governments. RGF’s active air purification is the most effective solution for viral transmission prevention for indoors spaces available today. Active purification works in every cubic cm of indoor air and surface space simultaneously and continuously. It differs to passive systems like filtration, UVC, Ionisation and PCO which rely on the air passing close to or through them to be treated.
Better Indoors’ combined positive pressure ventilation and active air purification solutions are economical and offer homeowners, landlords and building managers the most effective ability to meet the objectives recommended by SAGE.
The SAGE “Role of Ventilation in Controlling SARS-CoV-2 Transmission” refers to the following relevant documents (click on each to review document):
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. Ventilation guidanceThe advice in this document entitled CIBSE COVID-19 Ventilation Guidance V4 published 23 October 2020 is for building owners/managers and operators when reopening buildings following a period of inactivity and considering the requirements for the ventilation system.
The government’s modelling group says it is “unclear whether outbreaks can be contained by isolation and contact tracing. If a high proportion of asymptomatic cases are infectious, then containment is unlikely via these policies.”
Advice on mass gatherings is published in a paper from the Scientific Pandemic Influenza Group on Modelling (SPI-M-O) which recommends the government should not close down such meetings.
“The direct impact of stopping large public gatherings on the population-level spread of the epidemic is low”, says the paper, which goes on to suggest cancelling large events could drive people into smaller places where contagion was more likely.
Sage advises the government that restricting activities outside the household other than school and work would delay the peak of the coronavirus outbreak by three to five weeks and reduce overall cases by 50% to 60%.
It reiterates that school closures are unlikely to contain an outbreak, but could reduce the peak, if enacted early enough.
The advisory group also suggests that isolating suspected cases and quarantining households which have been in contact with suspected cases for 13 weeks could delay the peak of an outbreak and could reduce it by around 25%, says BuzzFeed.
Chief medical officer Chris Whitty tells the media that mass gatherings such as sports events and concerts may have to be cancelled, and schools closed for more than two months, if the UK is hit badly by coronavirus, reports The Guardian.
Two days later, Health Minister Edward Argar told BBC Radio 4’s Today programme that “decisions on large events and whether they should go ahead will be taken at the time on the basis of the evidence.”
Argar added that Whitty was “not saying there is a need for that now”, adding: “He’s been clear there is no reason or need for schools en masse to close.”
Sage writes: “There was agreement that Government should advise against greetings such as shaking hands and hugging, given existing evidence about the importance of hand hygiene.”
“A public message against shaking hands has additional value as a signal about the importance of hand hygiene,” the Sage sub-group, the Independent Scientific Pandemic Influenza Group on Behaviours (SPI-B), said.
The same day, reports The Guardian, Boris Johnson told a press conference broadcast on national television: “I was at a hospital the other night where I think there were a few coronavirus patients and I shook hands with everybody, you will be pleased to know, and I continue to shake hands.”
The government launches the “contain” phase of its coronavirus action plan, described as “detect early cases, follow up close contacts, and prevent the disease taking hold in this country for as long as is reasonably possible”.
The scientific advice published by the government says that cancelling large-scale public events wouldn’t contain the outbreak.
Sage advises the government that introducing social distancing measures could potentially decrease the total number of deaths by around 20% to 25%, and substantially reduce the peak of the infection.

That afternoon, Johnson advises the public to avoid unnecessary contact and travel and stay away from pubs and theatres.
“Now is the time for everyone to stop non-essential contact with others and to stop all unnecessary travel. We need people to start working from home where they possibly can. And you should avoid pubs, clubs, theatres and other such social venues,” he says. Pubs and resturants are ordered to shut four days later.
Vallance tells a select committee about South Korea’s testing and tracing strategy: “I think that would have been an absolutely brilliant thing to have had in January,” he says. “Public Health England has a capacity of about 4,000 or so [tests] per day. That is clearly not going to be enough going forward,” says Vallance, according to Research Professional News.

On 25 March, AstraZeneca released its most recent clinical trial results reporting an overall efficacy of 76% against symptomatic Covid-19 after two doses.
The vaccine is made in the UK at two sites in Oxford and Keele. A third plant in Wrexham puts the vaccine into vials and packages it up for distribution. AstraZeneca is working with suppliers in 15 other countries to make the vaccine, including sites in the US, Belgium, the Netherlands and India.
It has been given approval by the UK’s drug regulator, the European Medicines Agency (EMA) and has been granted emergency approval by the World Health Organization (WHO).
A conventional vaccine, using a harmless, weakened version of a common virus that causes colds in chimpanzees. Researchers have previously used this technology to produce vaccines against flu, Zika and Middle East Respiratory Syndrome (Mers).
The Oxford jab is the most widely used vaccine in the UK and has also been rolled out across the EU, though the European campaign has been stop-start due to intermittent safety concerns.
According to data from a real-world US study released on 29 March, the Pfizer vaccine reduces risk of infection by 80% two weeks or more after the first of two shots. The study by the US Centers for Disease Control and Prevention (CDC) evaluated the vaccine’s ability to protect against infection, including infections that did not cause symptoms.
The Pfizer jab is mostly made in Belgium. A manufacturing site has also been set up in the German town of Marburg.
The jab has been approved by the UK drug regulator, the EMA and has been granted emergency approval by the WHO.
Most vaccines rely on weakened or inactivated parts of the virus to provoke an immune response in their recipients, but the Pfizer version is synthetic.
It is made using messenger ribonucleic acid (also known as messenger RNA or mRNA). Whereas DNA is where we store our genetic information, mRNA – as its name suggests – transmits information to determine how our genes are expressed.
To put that another way, mRNA essentially puts DNA instructions into action. In the case of the Pfizer jab, the researchers synthesised a form of mRNA that will “cause our own cells to make a viral protein” from the Covid-19 coronavirus, says The New York Times.

The above CDC study found that the Moderna vaccine also reduces risk of infection by 80% two weeks or more after the first of two shots.
The vast majority of the vaccines are produced in Cambridge, Massachusetts, before being sent to be filled in Catalent’s biologics facility in Bloomington, Indiana, and Baxter’s site in Bloomington, Indiana.
There are also agreements in place with several manufacturing sites in Europe.
The vaccine has been approved by the UK’s drug regulator, the EMA and the US Food and Drug Administration (FDA).
The Moderna vaccine is, like the Pfizer jab, made using messenger ribonucleic acid (also known as messenger RNA or mRNA).
The UK, EU, US, Canada and Switzerland have bought the majority of the available Moderna vaccines, according to data compiled by researchers at Duke University’s Global Health Innovation Centre.
The company said in January that latest trials show the vaccine is 85% effective at preventing the most serious coronavirus symptoms after a single dose and 66% effective at preventing moderate to severe illness.
According to Johnson & Johnson, most of the vaccines are manufactured at a facility in Leiden in the Netherlands.
The vaccine is approved for use by the EMA, the FDA and the WHO.
Like the Oxford-AstraZeneca vaccine, the Janssen drug uses a modified adenovirus, a harmless, engineered virus that is injected into the patient. The adenovirus DNA triggers an immune response that helps protect the body from Covid-19 infection.
“Unlike other candidates, however, major US trials have focused on its effectiveness as a single dose,” says The Daily Telegraph. Johnson & Johnson is also conducting a second phase-three trial to look into the effects of two doses of the vaccine.
The US is planning to purchase 100 million additional doses of the vaccine having already shipped out nearly 3.9 million doses of the single-shot vaccine. The EU and the UK also have contracts with Johnson & Johnson.
In stage three trials in the UK, the vaccine was shown to be 96.4% effective against the original Covid strain and 89.3% effective against new variants, according to the company.
15,000 people participated in the trial, which was conducted during a period of “high transmission” when the “UK variant strain” discovered in Kent was “circulating widely”.
The Novavax vaccine will be manufactured at Fujifilm Diosynth Biotechnologies in Stockton-on-Tees and the GlaxoSmithKline plant in Barnard Castle.
The company is currently seeking approval from international regulatory bodies.
The vaccine works differently from other vaccines currently in use in the UK as it “combines an engineered protein” from the Covid virus with a “plant-based ingredient to help generate a stronger immune response”, Sky News reports.
The vaccine is yet to be rolled out, but the UK has ordered 60 million doses of the vaccine. The majority of the 362 million Covid vaccines ordered by Canada are Novavax doses, while the US and Indonesia are also awaiting deliveries.
According to the BBC, “interim data from late-stage trials in Turkey and Indonesia showed that the vaccine was 91.25% and 65.3% effective respectively”. Researchers in Brazil had said it was 78% effective in their clinical trials, but in January 2021 revised that to 50.4% after further calculations.
The vaccine is largely made at a Sinovac factory in Beijing.
The vaccine is approved in China and is on the way to getting approval by the WHO, according to a Sinovac spokesperson earlier this month. It is not approved by the UK’s drug regulator, the EMA or the FDA.
Coronavac is a traditional vaccine that uses dead viral particles to expose the immune system to the Covid virus without risking a serious disease response.
According to The Global Times, the vaccine is in use in China, Turkey, Indonesia, Jordan, the Philippines, Algeria and Ukraine. A further 17 countries have also “purchased Covid-19 vaccines developed by Chinese developers”, the paper adds.
Interim results of clinical trials in the UAE said the vaccine was 86% effective in preventing infection in early December, but Sinopharm announced later that month that phase three trials of the vaccine showed that it was 79% effective.
Also at a Sinovac-owned factory in Beijing. The UAE is also in talks to produce the China-developed jab.
Chinese medical authorities have approved the jab, as well as the UAE and Bahrain. It is not approved by the UK’s drug regulator, the EMA or the FDA.
Also a traditional vaccine, like the Coronavac vaccine.
Bahrain, China, Cambodia, Egypt, Hungary, Jordan, Macao, Morocco, Pakistan, Peru, Senegal, Serbia, Seychelles, United Arab Emirates and Zimbabwe are using the vaccine.
Based on the numbers of confirmed Covid cases from 21 days after the first dose of vaccine, the vaccine is 91.6%, according to a study published in The Lancet.
Most of the doses currently in circulation were produced at the newly opened Moscow-based “R-Pharm”, which has the capacity to produce ten million doses a month. India-based pharmaceuticals giant Virchow Group has also signed a deal “to produce 200 million doses of Sputnik V coronavirus vaccine a year”, according to The Moscow Times.
Russian drug authorities have approved the vaccine for use. The EMA began a rolling review of its safety in early March, while the FDA and UK drugs regulator are yet to approve its use.
Like the Oxford-AstraZeneca vaccine, Sputnik V is based on a modified version of a common cold virus that “is tailored to carry genetic instructions for making the coronavirus spike protein” and “triggers an immune response to protect” against Covid-19, The Guardian reports.
According to Statista, Russia has exported the vaccine to Algeria, Argentina, Belarus, Bolivia, Bosnia and Herzegovina, Brazil, China, Egypt, Honduras, Hungary, India, Iran and Italy.
Slovak Prime Minister Igor Matovic stepped down as leader of the country’s ruling coalition over a unilateral deal to purchase the vaccine, while France and Germany have opened negotiations with Vladimir Putin to discuss “cooperation” over vaccines, according to The Telegraph.
