Window Hepa Filter Fans
Air purifiers may work to some degree, but filtration is far more effective in getting rid of mold in the air. An air purifier with a HEPA filter would work best, along with reducing humidity levels.

When you search for air filtration systems online, there is a big chance you have come across the term HEPA. You might even be inundated with ads for window fans with HEPA filter or HEPA filter for window air conditioners.
If you are wondering what HEPA is or how it works, you are frankly not alone. HEPA is an important part of air filtration systems and is also gaining popularity. Therefore, it is crucial that you understand what it is, how it works, and how it can benefit you before you decide whether it is right for you or not.
Here is your guide to HEPA filters.
HEPA stands for High Efficiency Particulate Air. It is a type of mechanical air filter which works by forcing the air through an ultra-fine mesh which traps air pollutants like spores, pollen, dust mites, tobacco smoke, pet dander, and many others.
Window fans with HEPA filters were developed in the 40s mainly for use in laboratories. They were designed to protect scientist and other workers from radioactive dust and other harmful particles. Particles can range from floating contaminants that the human eye can see – for example, dust, spores, and dirt – to ultra microscopic particles like bacteria.
HEPA filters are designed to capture and trap very fine particles within its multiple layers of netting. This net is usually made of extremely fine fiberglass threads with gaps of various sizes. A HEPA filter is made airtight and made up of a dense sheet of pleated fibers which are then sealed in a frame made of plastic or metal.
What makes HEPA filters different from all other kinds of filters is it goes through rigorous testing and approvals. True HEPA filters for window AC or HEPA filter fans must meet the following standards before it can proudly carry the HEPA name:
- Ability to trap particles that are as small as 0.3 microns
- Efficiency of 99.97%
- U.S. Military Standard 282 (MIL-STD-282) Certification
Why You Need a HEPA Filter
Air pollution is not just an outdoor phenomenon. It is not exclusively car exhaust or the smoke coming out of industrial facilities. Indoors, the air quality can be just as bad, if not worse. Your home is also home to contaminants like dust, pollen, spores, bacteria, and many more.
If not addressed, these contaminants can pose health hazards, not to mention discomfort, to the inhabitants of the home. These pollutants are especially harmful for people with existing health issues like asthma or allergies.
A window fan with HEPA filter can work wonders for trapping even tiny pollutants and can help bring relief for allergy.
How HEPA Filters Work
The main goal of a window AC HEPA filter or a window fan HEPA filter is to trap air pollutants in its complex fiber web.
The HEPA filter is a part of the air purification system. Its job is rather simple, that is, when the fans of the air purifier sucks the indoor air in, the filter captures and traps the contaminants within. A HEPA filter traps particles using the following techniques:
- Inertial Impaction and Sieving – Large pollutants collide with the filter’s fibers and are trapped when they try to pass through.
- Interception – Medium particles touch the filter’s fiber and are grabbed directly.
- Diffusion – Smaller particles are diffused as they pass through the filter. They will collide and become trapped in the filter’s fiber eventually.
The Benefits of Window Fans with HEPA Filter
