Westbury is pleased to announce the launch of the new “Glasstech”bag filter range of ePM1 Bag Filters. The range will be promoted as ”Powered by Afpro media”
This innovative new product has been created in collaboration with International Air Filtration manufacturers Afpro Filters located in the Netherlands and utilizes their unique Micro Glass-fibre manufacturing process.
During production the fibre is sandwiched between two layers of synthetic media, making the resultant product look and handle the same as synthetic fibre whilst totally eradicating the possibility of fibre shedding and the consequential inhalation of glass fibres associated with all other micro-glassfibre bag filter manufacturers. This revolutionary new process also toughens up the product making it more robust than conventional materials for handling during installation.
The new Glasstech product is available in a range of sizes and is fully tested to ISO16890 ePM1

We are delighted to announce that David Burton, our recently appointed Health & Safety Representative has recently been successful in obtaining a NEBOSH General Certificate in Health Health & Safety. David has been with Westbury Filtermation for many years, originally joining the business when his Father’s business was acquired by the company.
We are delighted to announce the recent purchase of Total Filtration.
Total Filtration has been trading since 1970, manufacturing and supplying cartridges for hydraulics and oil filtration, focusing particularly on the marine industry. This is alongside their involvement in air filtration for the HVAC Industry. The highly experienced team from Total join us to compliment and expand the Westbury offering to customers by allowing us to grow our portfolio of in-house manufactured products whilst also increasing our penetration into the Welsh market place.
The new Division’s manufacturing capability alongside their warehouse and sales facilities will all remain in Cardiff, allowing the team to maintain the high level of customer service and technical support they are known for.
It has recently been announced that a new test standard for air filters ISO 16890 will be introduced towards the end of 2016. During the following 18 months the EN779 test standard will be phased out and replaced by the new standard.
The new test method shifts the focus on filtration performance to the classes of particulate recognised by many of the leading environmental authorities, including the World Health Organization.
You may well have heard of the particulate ranges PM1, PM2.5 & PM10 when reading about local environmental air quality targets and performance, these will become the new test ranges and, as such will result in the filter selection for specific needs being simplified.
So what does PM1 mean?
PM stands for Atmospheric Particulate Matter, the number 1 signifies that the particle range is for one micron diameter particles and smaller. In terms of quantity this is by far the largest particle range within the atmosphere. PM2.5 is the range that covers particles with a diameter of 2.5 Microns and less and finally PM10 particles 10 microns and below.
During testing the filters under test will be challenged with a range of particles from 10 microns down to 0.3 microns and the efficiency to PM1, PM2.5 and PM10 recorded. In order for a filter to be rated to PM1 or any of the other PM bands it will need to demonstrate a minimum efficiency of 50% and this will be recorded incrementally to the closest 5% – so a filter performing at 66% to PM1 particles will be rated at PM1 65%
For coarse filters the new standard will include filters that capture less than 50% of particles in the PM10 range – these will be known as “ISO Coarse” and will detail their PM10 performance i.e. “PM Coarse 45%”
There will be four specific grades of air filter:-
Each of the new grades will show the filter efficiency to the specific particle range, for example
40% PM Coarse
So what are the benefits of ISO 16890 ?
The new standard offers several improvements when compared to the EN779 Standard:-
It provides an international standard that can be recognised across the globe.
The EN779 test qualified fine filter performance at 0.4microns efficiency whereas ISO 16890 records their performance at a particle spectrum of 0.3 to 10 Microns.
Filters can be chosen for their specific performance related to the need of the application.
Fractional efficiencies of the filter prior to and after IPA discharge of any electrostatic properties can be seen.
