The Truth About Portable HEPA Filters

Energy efficient anything is all the rage now, and for good reason. Energy efficient construction, windows, and doors are effective at keeping pollutants out of your home and keeping your energy bills from skyrocketing. However, they are also pretty good at trapping pollutants in with you.

In fact, the Environmental Protection Agency estimates that indoor air can be 2 to 5 times more polluted than outdoor air. How can you ensure the health, safety, and comfort of your family? There is a small and simple machine that can help: portable HEPA filters.

What a Portable HEPA Air Filter Is

A portable HEPA filter is a portable and self-contained filtration system which is designed force indoor air through a series of ultra-fine mesh which traps air contaminants like dust, spores, pollen, smoke, animal dander, and many others.

Portable HEPA filter units may seem fancy but they are just basically an array of fibers which are randomly aligned to trap particulates more efficiently. These filters are made from either synthetic materials or from fiberglass.

HEPA stands for high efficiency particulate air. In order to call a portable air filter “HEPA”, it must meet many strict requirements. These requirements include:

  • They must remove at least 99.97% of particles.
  • They must have the ability to trap particles that are as small as 0.3 microns.
  • They must meet the requirements for a U.S. Military Standard 282 (MIL-STD-282) Certification.

A portable HEPA filter unit helps in cleaning and recirculating air and is used in many applications including in homes, offices, clinics, waiting rooms, and other confined areas. Manufacturers have even introduced portable HEPA filters for hospitals and portable HEPA air filters for kitchens, residential and commercial.

What Portable HEPA Filters are Trying to Keep Out

The job of portable HEPA filter systems is to get rid of pollutants like smoke, gases, dust, mites, mildew, mold, pet dander, allergens, volatile organic compounds, and other contaminants from the air indoors.

These contaminants circulate in the air indoors and can have negative effects on people’s health. Consistent exposure to these particles can cause eyes, nose, and throat irritation; headaches; allergies; asthma; bronchitis; kidney, liver, and nervous system damage; lung problems; and even heart problems and death.

How a Portable HEPA Filter Works

The job of a portable HEPA filter is to trap airborne pollutants within its complex fiber web to recirculate clean and contaminant free air in the indoor space.

The process is quite fascinating. It helps to think of the whole portable HEPA filter system like a net. However, it is a very sophisticated net that employs different techniques to trap even the tiniest of particle.

Portable HEPA filters catch and trap contaminants through the following processes.

  1. Direct Impact and Straining. Big particles fly into the HEPA filter and get stuck between the mesh fibers.
  2. Intercepting. Smaller particles that are not captured between the mesh fibers follow the air through the filter but since they are heavier than air, they do not move fast enough. Therefore, they are intercepted and end up getting stuck, as well.
  3. Diffusing. The really very small particles pass through the mesh and are too light to be intercepted. A HEPA filter can still capture them by bouncing them around the filter in a zigzag motion. They eventually hit the mesh fibers and get stuck.

Why You Need a Portable HEPA Filter

A portable HEPA filter is a great addition to any household, office space, or any indoor space because it offers a lot of benefits. They are built to be reliable and efficient and has been proven to promote better health.

Here are just some of the benefits of a portable HEPA air filter.

  • Efficiency rate of 99.97%. Filters cannot carry the HEPA name if they are unable to meet strict standards. Therefore, you are assured that it can do what it promises to do. Portable HEPA filters are just as efficient as other HEPA filters. Just because it is small does not mean it cannot do the job.
  • It helps with respiratory issues. HEPA filters can trap allergens that trigger respiratory complications like asthma, allergy, congestion, and even snoring.
  • It helps in energy efficiency. It makes your home’s air purification system more efficient. This means decreased energy costs and a longer lifespan for your HVAC system.
  • Its size. You can use it anywhere and anytime. It can fit in any room, is easily transportable, and handy.

With its many tested and proven benefits, you can ensure your family’s health, safety, and comfort with a portable HEPA filter.


What is a HEPA Filter?

During the Second World War, with America increasingly interested in the possibility of nuclear weaponry, they launched the Manhattan Project. As well as actually build the bombs, scientists had been tasked with a way to contain the radioactive contaminants released, which soon became the world’s first HEPA filter. 

HEPA is just an acronym for high-efficiency particulate absorbing, which is defined by the ability to capture 99.97% of particles 0.3 microns in size from the passing air. Filters that can achieve such efficiency earn the HEPA title, the gold standard of filtration. 

Although HEPA filters were originally designed for laboratory or industrial settings, the technology is now commonly seen in many consumer products, namely vehicles, vacuum cleaners and obviously air purifiers. 

Do Portable Air Conditioners have HEPA filters?

Portable air conditioner have a few kinds of air filter, including:

  • Pre-filter: these filters stop larger particles from entering the system. They’re typically washable, but they don’t eliminate smaller particles. 
  • Electrostatic Filter: these filters use electrostatic energy to attract passing particles, but they’re not really considered an efficient means of trapping dust. 
  • Ionisation Filter: these filters purify the air by attaching to and destroying the structure of microbes, like bacteria, viruses and fungi. These filters can help sufferers of allergies and/or asthma. 
  • Carbon Filter: Just as carbon filters absorb pollutants in water purifiers, they also bind to impurities in the air. Once expended, these filters must be replaced, though they are very affordable and usually sold in multi-packs.

Portable air conditioners are not guaranteed to have all of these filters, nor is it a certainty that they will contain a HEPA filter. It wholly depends on whether the product functions as an air conditioner, air purifier, or both. Air conditioners that do contain HEPA filters will be able to catch a larger range of particles, including those of smaller sizes. 

Do portable HEPA Filters help with COVID-19?

By definition, HEPA filters capture 99.97% of particles that are 0.3 microns in size. This is great for common household contaminants like dust and bacteria, which can measure as little as 0.5 and 0.3 microns respectively. 

Unfortunately, the COVID-19 virus is approximately 0.125 microns in size, which exceeds HEPA filter requirements. Though HEPA filters do help to reduce levels of airborne impurity, such filtration alone is ineffective as protection against the COVID-19 virus.

Although HEPA filters are unable to deal with COVID-19 directly, they do greatly improve the overall air quality, which will have significant health benefits. Consequently, HEPA filters can be considered a helpful measure against airborne threats more generally. 

Who uses a HEPA Filter Fan?

Certain industries involve higher levels of air pollutants, which increases the need for specialist filtration and ventilation solutions. Likewise, clinical environments demand greater levels of purity, hence installing portable HEPA filter fans to exhaust filtered air from negatively-pressurised isolation areas. 

However, HEPA filters are just as useful in a home or office, where they act as an in-room recirculating air purifier. Portable HEPA filter units are only efficient in terms of their 99.97% filtration, but also air flow. Baikal Mechanical HEPA fans draw as much as 600 cubic feet of air per minute (CFM), controlled by variable speed switch.  

Why use a HEPA Filter?

Whether they’re set up in residential, commercial, industrial or medical settings, the most obvious benefit of a HEPA filter is the removal of 99.97% of mentioned contaminants. Some suppliers, including Baikal Mechanical, also fit portable units with MERV 8 filters that eradicate up to 90% of particles like pollen, mould spores and dust mites. 

Conditions such as asthma or dust allergies may be alleviated by installing HEPA filters, as these responsible particles can be caught before entering your airways. The same applies to those with respiratory problems. By using a HEPA filter to reduce organic and chemical contaminants, you might notice improvements in mood and sleep, as well as respiratory and cardiovascular health benefits.
