High-Efficiency Filters: The best commercial air purifier for Your Air Quality Problems

Just as the names suggest, High-Efficiency Air Filtration solutions are a huge benefit in buildings to maintain a healthy indoor environment. This blog will explore all about High-Efficiency filters and how you can benefit from their installation.


In the face of the current pandemic and depleting air quality the need for efficient air filtration in various indoor areas has increased. The United States Environmental Protection Agency (EPA) estimates that indoor air can be two to five times more polluted than outdoor air.  Many businesses, building managers, and tenants are turning to high-efficiency air filters, because of these pressing concerns. 

High-efficiency air filtration systems are known to be the best air purifiers designed to help maintain the proper air quality in offices, commercial spaces, residential areas, workshops, and any other area where particles and other harmful contaminants can fill the air. Let us understand what makes them stand out. 

What are High-Efficiency Air filters?  

High-efficiency air filters use special membranes with air channels to improve the flow of air while they capture microscopic particles. Technically, these commercial air purifiers can remove at least 99.97% of dust, pollen, mold, bacteria, any airborne particle size of 0.3 microns (µm) and any other air contaminant.

The diameter specification of 0.3 microns responds to the most penetrating particle size. 

For comparison's sake, human hair is about 50 to 150 microns in diameter. So, a High-efficiency filter can trap particles several hundred times smaller than the width of a human hair.

 

Effectiveness of High-Efficiency Air Filters

The filtration efficiency of a High- efficiency filter is determined by the Minimum Efficiency Reporting Values, or MERVs rating. The rating is derived from a test method developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE).  Basically, MERVs report a filter's ability to capture larger particles between 0.3 and 10 microns (µm). 

Here is the table to understand the ratings for filtration efficiency of different electronic air cleaners.

MERV Rating 

Min. Particle Size

Typical control contaminant

1–4

> 10.0 μm

Pollen, dust mites, cockroach debris, sanding dust, spray paint dust, textile fibers, carpet fibers

5–8

10.0–3.0 μm 

Mold spores, dust mite debris, cat and dog dander, hair spray, fabric protector, dusting aids, pudding mix

9–12

3.0–1.0 μm

Legionella, humidifier dust, lead dust, milled flour, auto emission particulates, nebulizer droplets

13–16

1.0–0.3 μm 

Bacteria, droplet nuclei (sneeze), cooking oil, most smoke and insecticide dust, most face powder, most paint pigments

 

This value helps compare the performance of different filters. All other MERV values on each row have minimum removal percentages for that row's particle size. The higher the MERV rating the better the filter is at trapping specific types of particles. A High-efficiency air filter stands in the 13-16 MERV value range.

Need for the High-efficiency filter

Since indoor air is not circulated as much as the outside air, many airborne pollutants and harmful pathogens continue to thrive inside.  Majorly there are three types of pollutants found in an indoor environment i.e

Particulate pollutants (PM10, PM2.5, PM1, etc) Chemical pollutants (cigarette smoke, VOCs, and odor etc) and Biological contaminants (bacteria, viruses, fungi etc)

These can easily trigger respiratory infections, neurological problems, Ranging from eye and lung irritation to more severe cancer and decreased lung function and even airborne diseases such COVID-19 and H1N1 flu, etc.  

Under the right condition, High-efficiency air filtration systems can effectively remove such particles and airborne viruses that are associated with these health effects in exposed people. Also, These commercial air purifiers can lead to several immediate and long-term health benefits such as better sleep quality and increased life expectancy. 


Role of High-efficiency Air Filters in HVAC 

So many people spend a lot of time in spaces with mechanical heating, cooling, and ventilation (HVAC) systems. Having reliable air filtration in the ventilation system can dilute the emission from indoor sources by not carrying indoor air pollutants and biological pathogens.

In most cases, these electronic air purifiers can strike a good balance between air cleanliness and HVAC efficiency.  Not only these capture a greater percentage of particles and viruses on each pass, but lso increases the life of the HVAC system applied by reducing the air contaminant loads. This can further help in energy savings and lower maintenance costs.

High-efficiency filters vs standard filters: what to have in your home or office?

The common standard filters provide a basic level of filtration at a low cost. They’re often made of pleated cloth or paper to provide more surfaces for capturing relatively larger particles These further form colonies on the filters making them a secondary source of infections. Also,  ineffective in the case of harmful airborne pathogens such as SARS-CoV-2 and penetrative particles( <0.3 microns). 

ASHRAE provides many guidelines to help prevent the airborne transmission of COVID-19. One of their recommendations is using air filters with at least a MERV 13 rating. That is why we are seeing a switch from standard filters to High-efficiency electronic air cleaners in residential and commercial buildings like offices, malls, homes, etc.

Is UV Light a New Normal For Domestic Architecture?

Image
  Solar energy has existed as long as the sun for over 5 billion years, and it has been an essential element for the survival of various inhabitants, including animals, birds, and even microorganisms. From converting sunlight into heat for keeping themselves warm in winters to igniting a fire for cooking, people have been using solar energy for thousands of years in a variety of ways for domestic purposes. Apart from that, Solar radiation is the main source of Ultraviolet rays, is also a known solution for killing the vast majority of harmful microorganisms. The application of ultraviolet light for sanitation purposes has been recognized for over a hundred years. The Germicidal properties of UV rays were first discovered in 1877. Later in 1903, Niels Ryberg Finsen received a Nobel Prize for his use of Ultraviolet light to combat tuberculosis. Making its way upwards in the 1930s, the first UV light tubular lamp was discovered, contributing to the discovery of truly significant resea...

Protecting schools and universities from Coronavirus in the air with UV light sanitizers

Image
As India debates to open schools and universities, the pressing problem is how to clean Coronavirus from the air. A recommended measure is UV light sanitizers to ensure healthy indoor air.  When the schools and colleges finally open, millions of students and staff attend public and private education institutions each day in India. At any given time, they are susceptible to various types of airborne illnesses. The transmission of diseases communicated through the air includes tuberculosis, influenza and the common cold. Coronavirus is the newest entrant to the list. Studies report that airborne disease transmission can either be controlled or accelerated by the school or universities’ HVAC equipment.  Source   When the schools and colleges start reopening, those facilities will have to adopt active infection protocols to control the spread of Coronavirus. One such measure that is being recommended by international bodies such as ASHRAE is UV light sanitizer, UV light air ...
