The high transmission rate of coronavirus (COVID-19) has prompted the Center for Disease Control and Prevention (CDC) to recommend that everyone in the U.S. wear nonsurgical face masks when going out in public because people infected with the virus may emit aerosols (particulates or microorganisms) when they talk or breathe. These infectious viral particles can float or drift around in the air. This has raised concerns about indoor air quality and the potential for airborne transmission through an HVAC system. Therefore, in many industries from healthcare to manufacturing, facilities managers are exploring whether their buildings are equipped to reduce the threat of infection.
To help our customers gain a better understanding of HVAC filtration as it relates to COVID-19 and other airborne transmissions, our filtration experts have compiled a list of frequently asked questions.
The spread of the novel coronavirus (COVID-19) mainly occurs through respiratory droplet transfer from person-to-person within a close range of about six feet according to the CDC. The virus can also be transmitted on objects and surfaces that a contagious person may cough on, sneeze on, or touch. Pathogens can also travel on dust and dirt particles as those particles move through the air. Therefore, the potential for airborne transmission through an HVAC system exists.
HVAC filters can reduce but not eliminate the threat of infection. The coronavirus and the particulate it travels on is very small in size, and can range from submicron (less than 1.0 micron in size) and larger. High-efficiency filters on the market today can trap particulate sizes that are likely to remain in the air. Selecting the right filter can reduce risk while improving the quality of indoor air.
When selecting a filter to combat the threat of airborne transmission, you have to consider the level of filtration wanted versus effective system operation. HEPA and ULPA filters provide the highest rate of effectiveness, but many HVAC systems would not be able to use them without extensive retrofit. We suggest a minimum efficiency reporting value (MERV) rating of 14 to 16 for most HVAC systems. Sub-HEPA, HEPA and ULPA filters can be used where needed and for systems which can use them effectively. Where systems cannot accommodate higher efficiency filters, MERV 13 filters can provide significant improvement in efficiency and can be easily installed in the majority of HVAC and residential units. There are several filters in Parker’s line that can be used as part of an overall comprehensive strategy. We can assist you to determine which filter or filters would be the best choice for your application.
Our best recommendation is to visit the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) website. ASHRAE has developed proactive guidance for building industry professionals to help address the ongoing concerns of the coronavirus (COVID-19) outbreak. There you can access the latest response resources from ASHRAE and other leading organizations with respect to the operation and maintenance of HVAC systems.
MERV stands for “minimum efficiency reporting value.” It’s a rating system that was developed by the American Society of Heating, Refrigeration and Air Conditioning Engineers (or ASHRAE). MERV values range from 1 to 16. The higher the MERV value, the more efficient the filter will be at trapping airborne particles. When selecting a filter to combat the threat of airborne transmission, we suggest a MERV rating of 13 to 16.
Do you have an HVAC filter for residential applications?
Yes, we recommend Puro-Green or DP-Green MERV 13 filters for use in residential applications. Our MERV 13 high-efficiency rigid filters can be used in residential HVAC systems to achieve better indoor air quality without the need to retrofit systems.
Today's historic global pandemic has raised awareness of the importance of maintaining healthy breathable air inside buildings. Parker is dedicated to providing honest and transparent information about our filtration products to help customers decide which technologies offer the highest chances of trapping virulent pathogens before they enter a building or circulate to different rooms. Parker’s products can reduce airborne particulate in a controlled environment. They would not eliminate the risk of exposure to airborne viruses but can be part of a comprehensive plan to help reduce that risk.
After more than a century of experience serving our customers, Parker is often called to the table for the collaborations that help to solve the most complex engineering challenges. We help them bring their ideas to light. We are a trusted partner, working alongside our customers to enable technology breakthroughs that change the world for the better.

Looking ahead to the future of industry, with all the advancements in technology that the Industrial Internet of Things (IIoT) holds in store, one might rightly wonder if pneumatics will still have pride of place on the production line. After all, it’s basically just gas or air passing through tubes! Surely all the innovation that’s happening with digitalisation will mean that IIoT components will become much more important than the pneumatics?
Pneumatics and IIoT inseparable
In actual fact, the real answer is that the two technologies will most likely become inseparable because they perform equally important functions that are increasingly becoming interdependent. Parker’s recent ‘Factory of the Future’ market research has revealed that pneumatic technology will indeed remain a critical component in the digital manufacturing field for the foreseeable future. Although pneumatic equipment indeed functions through pressurised gas or air moving through tubes, these tubes remain the ‘veins’ of the factory, delivering fast, precise and efficient movement on complex automation lines and facilitating quick and easy assembly, cleaning and a host of other functions on the production floor.
Pneumatic designs compliment approach of Industry 4.0
Since pneumatics have been around for quite some time, they already offer high reliability and efficiency, and their designs naturally complement the modular approach of Industry 4.0. In the increasingly digital manufacturing sphere, pneumatic systems are being adapted to answer the need for real-time process data through the incorporation of IIoT enabled nodes and sensors.
Although some pneumatics manufacturers have been slow off the mark to follow the digitalisation trend, Parker recognised the opportunity to serve customers with industry-leading connectivity and safety solutions well in advance. For instance, our entire product development cycle is now focused on making devices ‘smart’ by ensuring that they are able to communicate their status to the rest of the network. OEMs can now easily use these smart pneumatics equipped with cost-efficient sensors to intelligently monitor the real-time status, positioning, velocity, condition and efficiency of the various components that make up the modern automation line.
Although there is still a long road to travel in order to realise the ultimate vision of Industry 4.0, the intermediate period will see the gradual introduction of these smart products that offer both traditional control functions and actionable intelligence. The evolution of manufacturing is contingent upon the development and continuous improvement of this actionable intelligence, giving users the ability to track the uptime and availability of the machines in their plant. The analytics from this data will enable significant operational cost savings, for instance by performing predictive maintenance and achieving optimised operations using continuous position sensing.
Choices ahead to future-proof designs
While the technology is still in a state of flux, machine builders and their component suppliers will now need to make careful choices in order to future-proof their designs. Parker believes that open-source, low-cost Industrial Ethernet (IE)-based components and subsystems is the answer to this challenge, and so our recent product development efforts have been based on IO-Link enabled connectivity and network solutions.
IO-Link enabled products are just one example of how Parker, leading with purpose, is providing customers with cutting edge technologies for use in globalised manufacturing operations. Regardless of location, the use of IE and IO-Link network nodes make the control, safety and maintenance of a range of different devices, machines, systems and users simple and cost-effective.
Ensuring that key automation components such as pneumatic valves are IIoT-enabled is an excellent way of creating white space opportunities for innovation in the factory of the future.

Reliable functionality and efficient economy are the key drivers to the innovation in the development of marine engines. Improvements in the design efficiency in the maritime industry over the past three decades show engine applications have had the largest increase.
Current filtration practices in hydraulic and lubrication throughout marine applications center around preventing contamination from getting into the machinery, thereby delivering improved component life. However, purely prescriptive maintenance of filter elements causes unnecessary maintenance costs and unanticipated downtime. Our white paper demonstrates why a move to more predictive maintenance with condition-based maintenance of filter elements enables the operations team to optimize the use of resources.
Factors that influence the mechanics of filtration
Download our technical white paper: Towards the Predictive Maintenance of Mechanical Filters to learn about the scientific testing behind the data substantiating the results.
Combustion and lubrication are complicated events with usual uncertainties in their operating conditions. A mechanical filtration system is an integral part of lubrication and combustion units, and may display an uncertain performance due to the sensitive behavior of several upstream and downstream components. On one hand, the flow and fluid characteristics along with the varying ambient conditions strongly impact the filter’s performance. On the other hand, unpredictable characteristics of contamination including the particle size and shape, specific weight and concentration of solids, the chemical composition of impurities and diverse intermolecular and adhesive forces highly influence the mechanics of filtration. The source of foreign matter in hydraulic liquids and underlying mechanisms of generating solid particles such as wear, welding slag, ingressed contamination, etc. is very complex, and a holistic analysis from the perspective of the system’s entirety would lead to superficial knowledge about oil quality.
Moving from preventive to predictive maintenance
The presence of solid particles in the lubricant is a major cause of failures in hydraulic systems. Studies show that over 80% of the failures of hydraulic units are due to the foreign matter in the hydraulic oil. From a combustion perspective, stringent regulations on the emissions and realistic certification processes demand more efficient filtration practices.
The conventional practice of preventive maintenance of mechanical filters is purely time-based. This may cause additional maintenance costs if the filter element is still in relatively good condition, and unanticipated operational downtime if the element is clogged or damaged before its prescribed lifetime. Therefore, the need for switching from preventive/reactive maintenance to predictive maintenance is obvious, where the information about the element’s lifetime is critical without missing the focus on the optimal response to the key performance requirements:
Optimizing filter predictive maintenance with sensors
In order to optimize the filter’s maintenance, the analysis of the performance over time must be precise. This objective can be achieved by improving the quality and relevance of the filter’s test data provided by the deployed sensors at the right locations of the test bench. Performance and statistics based predictive approach rely on the robustness and validity of the models that correlate influential factors to enable more accurate estimations of the filter element’s lifetime.
Predicting the lifetime of a mechanical filter is, therefore, a major challenge due to the dynamics associated with the filtration as a process itself. Depending on the areas of application, this estimate requires knowledge about all those processes that alter the operation settings, fluid condition, porous media properties, and the filter’s status.
Developing a framework for the data correlations
The rapid growth of sensing technologies has made oil condition monitoring a reality. However, the dynamics associated with the phase separation through porous media and ambiguous variation in the filtration phenomenon due to the uncertain operating conditions unleash the complexity in realizing the prognostics of a hydraulic or fuel filter.
Therefore, a laboratory-based experimental framework has been developed to quantify the effect of fluid/flow conditions on filtration. Here, the identification of the right filtration parameter should lead to the analysis of the filter element’s condition and predict its residual lifetime.A smarter shift to condition-based maintenance
As a filter’s maintenance practices cause unnecessary maintenance costs and unanticipated downtime, condition-based maintenance enables the optimum utilization of resources. This foresees a new horizon where the preventive or reactive maintenance could be replaced by the state-of-the-art predictive maintenance models in the context of industry 4.0 and the IoT.
