BYD Solutions Ltd Air Clean Purification / Anti-Bacterial Division “Dexpert UK” provides a revolutionary new concept in the purification and cleaning of internal air.

Once applied our application will in any way be beneficial to the occupant’s health because they breathe less VOCs emitted from products, smells produced whilst using the property in general, but also all the poor air quality externally with levels of NO2 (Nitrogen Oxide) entering their buildings. It will also help kill the spread of airborne bacteria making the internal air clean and fresh to breath.

People who suffer from poor air quality generally notice their symptoms after several hours at work / school and feel better after they have left the building or when they have been away from the building for a weekend or holiday.  So providing staff, students & visitors with the very best air quality can only be a good thing.

The benefits of our system are:

  • Easy Application
  • No building alteration required
  • Eco friendly not requiring any power
  • No unsightly box’s fitted to walls
  • Treatment is totally invisible.
  • No maintenance or cleaning required
  • Once applied our system will clean the internal air 24 hours a day 7 days a week
  • Lasts up to 10 years before renewing
  • Will not affect the day to day running of your building
  • Can be applied in already occupied offices with no disruption at all

Our solution is an effective and especially economic way to remove air pollutants, bacteria, germs and odors by treating surfaces of a premises preferably the ceilings with our system.

EnviroVent Ltd

EnviroVent is the UK’s leading manufacturer, supplier and installer of energy efficient and sustainable ventilation products to improve indoor air quality and control the humidity levels which cause condensation and mould problems.

For over 20 years, EnviroVent has tackled condensation and mould in over a million properties. Our award winning range of condensation control products come with long-term warranties, and are fitted by qualified professional engineers.

Manufacturing onsite also enables us to maintain the strictest levels of quality control and testing.

The effect of not having good indoor air quality is dramatic. The average person spends 90% of their time indoors and 70% of this time is spent in their own home. The indoor living environment is therefore crucial to the health of the occupants.

The modern home has become increasingly energy conscious. We have insulated, draught proofed, double glazed and progressively sealed our homes from an essential supply of fresh air. This may save energy, however we’re now breathing in stale, contaminated, humid air.

EnviroVent has a solution for every type of property, you can be assured that not only will your indoor air quality be dramatically improved, but so will your health and your heating bills. Visit our website at or call us on 0345 27 27 810 to speak with one of our ventilation specialists.

GEM Air Quality Ltd

GEM Air Quality Ltd are independent air quality consultants, specialising in air quality assessments for planning and Environmental Impact Assessment (EIA) purposes.

These assessments typically examine the impact of both the construction and operational phases of a particular development.  The impacts are compared against UK air quality objectives and/or significance criteria defined within relevant air quality guidance.

Depending on the scale of these impacts the air quality assessment may also discuss the mitigation measures that will need to be adopted.  Such measures will focus on the reduction of emissions during the construction phase, plus any measures relating to the introduction of new exposure into an area of existing poor air quality and/or the wider impacts of a proposed development on local air quality.

Following publication of the London Plan and the Mayor of London’s Sustainable Design and Control Supplementary Planning Guidance (SPG) we also undertake “Air Quality Neutral” assessments, which are now required for all major new developments.  These assessments focus on the building and transport emissions over a year and compare these with a benchmarked emission rate.

Established in early 2009, GEM Air Quality Ltd has established a wide customer base, including planners, architects and developers.  Through its employees, GEM Air Quality Ltd has over 12 years experience in the field of air quality assessment and monitoring having completed numerous air quality assessments and monitoring projects.

GRAMM SmogStop

GRAMM is the UK leading specialist in the design, supply & installation of environmental acoustic barriers with over 20 years of experience. We have constructed literally 1,000’s of Km’s of acoustic barriers of all types of materials throughout the UK and Europe.

GRAMM is the exclusive UK partner for SmogStop.

GRAMM SmogStop Barrier reduces air and noise pollution levels in surrounding neighbourhoods, and takes a two-pronged approach to reducing air pollution from major roads, highways and railways.

The patented aerodynamic design reduces pollution levels by enhancing dispersion so that neighbouring residents can breathe easier. At the same time, a proprietary coating on the barrier actually breaks down the NOx and VOCs that produce smog, transforming them into harmless by-products.

GRAMM SmogStop Barrier’s angled baffle and double-walled design serve two main purposes. First, they direct traffic emissions between the two walls, where a photo catalytic coating treats the pollutants. Second, they generate vortexes and enhance vertical mixing of emissions with clean air, further decreasing pollution levels in surrounding neighbourhoods.

The proprietary coating we’ve developed transforms smog-producing NOX and VOCs into harmless gases and water, powered purely by sunlight.

GRAMM SmogStop Barrier incorporates ClearSoundBlok: a sound-reducing, break-resistant and highly transparent grade of acrylic.

The result? A dramatic reduction in noise and air pollution — without sacrificing sunlight.

Over the course of a year, a single kilometre of GRAMM SmogStop Barrier can remove 16 tonnes of NOX— the equivalent of taking 200,000 cars off that stretch of road.
