Therefore, maintaining healthy air quality is important to help prevent the spread of allergens, germs, and other airborne illnesses. As a result, many of us have air purifiers.

What Is a True Hepa Filter

We tend to think of air pollution as something that happens outside. But that’s not always the case. Even inside our home, there are dust mites and dirt to worry about. Indoor air pollution can irritate your lungs and contribute to allergies and asthma. Do HEPA air filters really work? A true Hepa filter is designed to remove airborne particulates and bacteria using HEPA technology as the primary filtration. They effectively absorb airborne particles and trap them in the filter including dust mites, mold spores, pollen, and pet dander. All these allergens and bacteria in the air inside your home can cause problems even if your family doesn’t suffer from allergies or asthma. Using HEPA filters can trap these pollutants and may help bring relief.

Be careful: You may come across HEPA impostors such as “HEPA-like” or “HEPA-style”. They make a product look like a HEPA filter, but without meeting those strict standards.

Portable Hepa Filtration

You can find HEPA filters in most air purifiers. These portable units may work for a single room. Therefore, portable HEPA filtration is a great choice. If you are considering buying an air purifier with HEPA filter technology, be sure you buy one that is big enough for the room where you plan to use it. The plus of portable air purifiers is that you can move it from room to room if needed. The best place for a unit is the room where you spend most of your time. Mostly in your bedroom. But, it is not a must. You may choose any room according to your own needs.

How Do Hepa Filters Work

HEPA stands for high-efficiency particulate air. A HEPA filter is a type of mechanical air filter. It forces air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. Depending on the size of the particle, this can happen in four different ways: Inertial Impaction, Diffusion, Interception, or Sieving.

How do true HEPA filters work

Larger contaminants are trapped via inertial impaction and sieving. The particles collide with the fibers and are trapped while attempting to travel through the fibers. Medium sized particles, as they move through the filter, are grabbed by the fibers via interception. Smaller particles are dissipated as they travel through the filter and eventually collide with fibers and are trapped.

Many vacuum cleaners also use HEPA filters as part of their filtration systems. This is good for asthma and allergy sufferers. Why is it so? Because the HEPA filter traps the fine particles (such as pollen and dust mite feces) which trigger allergy and asthma symptoms.

Mold is a type of fungus that only needs moisture and warmth to grow. It reproduces from tiny spores that cannot be even seen and floats through the air both indoors and outdoors. Typically mold accumulates in areas where moisture levels are high. Allergies, dizziness, headaches, and fatigue are a few effects that can emerge from vulnerability to mold. True HEPA filters trap airborne spores and prevent them from sticking to walls and reproducing.

Allergies

Pollen, dust, dirt, and other airborne particles can irritate allergies. All of these make us miserable with runny noses, itchy eyes or skin, sneezing, coughing. A true HEPA filtration system removes airborne particles from the air quickly.
