About

Background

Our sister company, (AHP), manufactures state-of-the-art shower heads and conducts world-leading R&D for advancing Legionella control procedures that help reduce the well-documented risks to health associated with conventional showering methods; attributed to a widespread source of infections that are avoidable. Including Legionnaires’ disease, widely-believed to be often misdiagnosed as pneumonia, and Pontiac fever, a flu-like illness, often believed to include cases of freshers-flu.

Late 1980’s, AHP founded the SafePurge Legionella control procedures - providing an alternative and more dependable means of controlling Legionella from showers; procedures later advocated by National Health & Safety Authorities, National Health Authorities, European work group (EWGLI) and leading scientists around the world. Safepurge showers features in the UK’s Health & Safety Executive’s videos, filmed at Holiday Inn Hotels and the Royal Liverpool University Teaching Hospitals. Further independent scientific trials, carried out at Catterick -2009, challenging different Legionella control methods, once again confirming the dependability of our principles and procedures; leading to national military roll out programs for Safepurge showers. However, employing advanced SafePurge technology considerably raises the price-point of showering installations, shown to restrain a wider-appeal for this healthier showering method.

Broadening accessibility

Broadening accessibility for healthier & sustainable showering is reliant upon first inventing and developing an improved engineering approach, which is reliable, practical and cost-effective. Setting out to achieve this, AHP revisited the common Legionella control challenges inherited from the design concept of traditional shower heads, which has evolved little since Legionella was discovered. AHP has now accomplished a fundamental design breakthrough - inventing and developing a unique shower head, capturing a spray plate having orbital positioning; evolving the design concept of traditional shower heads for healthier & sustainable showering. Introducing RefreshFlip shower heads, available for upgrading conventional showering facilities and installed at a price-point similar to fitting typical traditional shower heads.

RefreshFlip Shower Heads

Establishing the Best Practice Benchmark for healthier & sustainable showering, across a wide range of business sectors and also now for households. We welcome the opportunity of supporting your healthier and sustainable showering requirements.

Technical support

For decades, AHP continues supporting regional, national and global organisations - for projects ranging in size, from single shower installations, to those requiring many thousands of showers, e.g. Ministerial Departments, UK Gov.

Fereno now welcomes the opportunity of supporting your healthier showering requirements at home, and broadening the accessibility of healthier and sustainable showering - for all.

Our History

1987

Our sister company, AHP, founded to research new ways of improving traditional Legionella control procedures and through the advancement of showering technology.

1995

Independent scientific trials conducted by the Royal Liverpool University Teaching Hospitals; Safepurge Legionella control principles-technologies-procedures proven.

1997

AHP incorporated. Manufacturing and testing facility established.

1998

Safepurge control procedure announced during a state of the art lecture at the International Symposium on Legionella, Edinburgh.

2001

The Health & Safety Commission & Executive advocate the Safepurge Legionella control procedure, described in ACoP & Guidance (L8, technical guidance, paragraph 166).

2003

HSE’s audit check lists describe the Safepurge procedure. Safepurge showers feature in the HSE’s Legionella control videos, filmed at Holiday Inn Hotels and at the Royal Liverpool University Hospitals.

2005

Preventing Legionellosis (USA publication); Safepurge references. Author, Doctor William F. McCoy.

2006

Department of Health (HTM04-01: part B), describes the Safepurge Legionella control procedure as an effective control means and how it should not be confused with other shower types.

EWGLI (European Guidelines), Health & Safety Authorities, National Health Authorities and leading scientists around the world have published the Safepurge Legionella control procedure.

2009

Scientific trials carried out at Catterick Garrison, England; 56 Safepurge showers successfully trialled against other shower types; leading to a Safepurge military roll out program. AHP principles, technology & procedures confirmed suitable even for the very largest property estates.

2014

DoH, Health Technical Memorandum 04–01: 7.44. HSE, HSG274 Part 2; 2.167, 2.168; describes the Safepurge control procedure as an effective control means.

Many thousands of Safepurge showers sold worldwide - supporting projects ranging in size from just one installation to those requiring several thousands, e.g. UK Gov ministerial departments.

2017

Published - Independent studies identifying a large proportion of household shower heads found contaminated with legionella bacteria.

Fereno Research Programme - launched by Director Steve Bennett. Mission - to invent and develop an improved engineering approach for addressing persistent legionella control challenges inherent in traditional household shower head design.

2020

RefreshFlip Shower Head program successfully completed; closing the Legionella control loop for the traditional shower head type. Incorporating principle-based and interconnected innovations for sustainable Legionella control and for when showers are in regular use, littler use and during disused periods.

2024

RefreshFlip shower head product launch - commercial sectors; continuing the traditional shower head theme expected by hotel guests and encouraging the wiser and wider-use of legionella control procedures, through the promotion of cleaner-fresher showers - for healthier and sustainable showering.

2025

Fereno showers launch. Continuing a long term commitment to making safer showering available for all. And now for households.

Providing much needed Public Health Information, helping those take practical steps to protect themselves from the well documented and reasonably foreseeable potential risks to health from traditional showering methods.
