  1. What To Expect From Westbury’s Free-of-Charge Filter Survey

    Leave a Comment

    In the realm of HVAC systems, the Air Handling Unit (AHU) plays a crucial role in maintaining indoor air quality and comfort within commercial and industrial spaces. Filtration is a critical aspect of the way in which an AHU performs, not only determining indoor air quality, but also protecting and prolonging the lifespan of other system components such as heating/cooling coils, attenuators and fans.

    As such it is of vital importance that the filters selected are properly specified according to local conditions and the desired level of cleanliness within the facility. Needless to say, the fitment of the filters is also crucial, so as to avoid air bypass and unnecessary contamination.

    Comprehensive Inspection

    A thorough inspection is the starting point of a survey of filtration requirements. Your nominated Westbury representative can arrange to review the filtration currently installed and help to spot any issues. These range from ill-fitting filters, to missing clips, damaged filters and incorrectly orientated products.

    Alongside this trouble-shooting, we can also identify opportunities for improvements. These can deliver enormous benefits, such as reduced energy costs, lower filter consumables expenditure and reduced downtime, all whilst IMPROVING indoor air quality!

    Filter Replacement and licensed waste disposal

    When our engineers visit your site to survey, they will also review the change-out regime and can work with you to develop a schedule for optimum filter change point. In addition, Westbury can also offer qualified engineers capable of replacing your filters efficiently and effectively, before collecting and disposing of used filters under our waste carrier’s license.



    Contact us today to book your free of charge site survey and filtration review to see what you could save.

  4. Air Filter Selection Guide

    Leave a Comment

    When it comes to selecting HVAC air filters, there are several factors to consider to ensure that you choose the right options for your application:


    1. Filter Efficiency
    The first selection consideration is the efficiency rating, or the capability of the filter to capture particulate. The higher the efficiency, the more effective the filter will be in capturing smaller particles. You can read more about filter efficiency here.


    2. Airflow Resistance
    Resistance to airflow is crucial factor to consider when selecting any air filter. Higher efficiency filters generally have a greater resistance to airflow, which brings with it increased energy consumption. Filter selection should also be considered in the context of the HVAC system as a whole, to ensure that the fan and other components can deliver sufficient quantities of air, allowing for the resistance to airflow that the filter(s) present.

    The ideal filter selection should deliver a low resistance to airflow to minimise energy costs. A filter that can maintain low resistance for a long period of time, will deliver the lowest costs of operation. You can read more about minimising life cycle costs by clicking here.

    3. Particle Size
    The size of the particulate that the filters will be exposed to should also be considered when selecting air filters – different filters are designed to capture specific particle sizes. In many cases a multi-stage approach is preferred, with coarse pre-filters removing large particulate and higher efficiency secondary filters positioned downstream to remove finer particulate.

    4. Environmental Factors
    Local environmental factors, such as the concentration of particulates and proximity to sources of air contamination should also be considered when selecting an air filter. It is important to remember that these factors are variable and will be influenced by factors such as seasonal changes, nearby construction works, time of day, etc.  This should be considered when selecting filtration and planning appropriate maintenance regimes.


    Taking these factors into account demonstrates that appropriate filter selection is vital for achieving and maintaining appropriate air quality and optimal system performance. Consideration of filter efficiency, airflow resistance, particulate size and environmental conditions will all be important. The correct selections in the balance of these considerations will ensure that your systems can operate efficiently and effectively to recover lost revenues, reduce costs and deliver improved efficiencies.

  5. Westbury introduces striking new packaging!

    Leave a Comment

    In the demanding environments that Westbury’s clients operate in, the importance of the way that our filtration products are packaged can sometimes be under-estimated.

    Not only do our boxes need to be sufficiently robust to protect the delicate filters inside, but they also need to be easily identifiable and simple & safe to handle; after all, many of our clients have a huge variety of locations on site that the boxes need to be taken to after delivery.

    Westbury’s aim in developing the new packaging was to retain the great benefits of our previous packaging solutions, such as carrying handles and bespoke labelling options, whilst also introducing improvements in construction and incorporating our latest imagery.

    We know that sustainability is also important to our clients, so we chose to continue with the use of unbleached & recyclable materials and to utilise an elegant design language so as to minimise environmental impacts.

    With the support of our long-standing partner Greyhound Box Ltd, we were able to develop a versatile packaging solution, which meets the demands of our customers whilst also allowing Westbury to reduce our environmental impact and enhance efficiencies at the factory.

    All in all, the collaboration has been a great success and we can’t wait to see these boxes out there in plantrooms across the country!

  10. Comparing Air Filter Performance

    Leave a Comment

    Indoor air quality has become a growing concern in recent years as people spend more time indoors.

    Properly specified and maintained Heating Ventilation & Air Conditioning (HVAC) systems can play a crucial role in ensuring that people and processes are properly protected. Air filtration within HVAC systems is critical in ensuring the air we breathe is clean, but how can users verify the performance of their air filters?

    Understanding ISO 16890 Testing


    ISO 16890 is the globally recognised standard for evaluating air filters used in HVAC systems. In 2016 it replaced the previous EN779 standard and provides users with a useful tool for comparing the filtration performance & energy efficiency of air filtration solutions.

    The results of air filter testing against ISO 16890 are expressed in relation to particulate sizes (1 micron, 2.5 micron & 10 micron). This allows users to assess the efficiency performance of filters against particulate size and make straightforward comparisons.

    Reputable filter providers will have access to an ongoing program of independent filter testing and should be able to provide ISO 16890 guidance on request.


    Beware of misleading claims!

    Despite the best efforts of industry leaders and filtration experts to implement ISO 16890 in a way which increases transparency for users, there remain many misleading claims within the air filtration marketplace.

    Caution should be exercised where filter providers claim that additional approvals are required to deliver “compliance”. Any claims that further approvals or trade-body memberships are required are false and should be dismissed.

    Similarly, any reputable filter provider should be conversant in the terminology of ISO 16890. Many users of air filtration products are still most familiar with the terminology of previous filter standards and our role as industry experts is to be able to talk both “languages”, for the benefit of air filtration users.

    For further advice on how filter test standards have evolved and for a clear & honest conversation about the points discussed above, contact Westbury today.
