HomeUncategorizedHEPA Filters and Their Use

Air pollution is not exclusively outdoors. It can occur inside your home as well. Dust mites, dirt, mold spores, animal hair and pollen hidden in carpet fibers, behind the curtains, under your bed and other parts of your home can be part of the indoor home circulation and can irritate your respiratory system.

Households, especially those with members with allergies or any other respiratory-related condition, should consider getting a premium quality air filter. If you’ve been checking out some devices in the market you’ve probably encountered HEPA filters and their use.

HEPA is an initial for High Efficiency Particulate Air, which is basically a type of air filter that has medical, automobile, aircraft, domestic and commercial applications. It is made of a mat of randomly arranged fibers which are made of fiberglass. The key factor to its efficiency is the diameter which is between 0.5 to 2.0 micrometers. Other factors are the face velocity and filter thickness.

In order to be called a HEPA filter, the device must be tested and approved by the regulatory body. The Institute of Environmental Sciences and Technology prescribes that a filter to be called HEPA must trap 99.97% of particulates 0.3 microns or larger. This is the standard that must be achieved in order to be granted the name “HEPA”.

Some vacuum cleaners are equipped with filters but the efficiency of HEPA filters are unparalleled. These filters use a fine network of fibers to trap air contaminants using three different mechanisms: diffusion, impaction and interception.

Smaller particles are dispersed as they move through the filter and eventually run into a fiber and get trapped. Medium-sized particles are snatched by fibers as they move through a tube. Larger pollutants are caught by the fibers through impaction.

Using HEPA filters in your home will help take the worry of allergy-causing airborne particles away from you. However, the particles suspended in air are not the only ones in your home. There are far more in your rugs, bedding, and drapes, as well as those resting on tabletops and countertops. For this reason, it’s important to keep these areas clean. It’s also important, when possible, to get rid of the source of allergens and irritants. For example, the only effective way to keep tobacco smoke out of your home is to not smoke.

Indoor air quality is vital to your overall health. HEPA filters can take up a significant amount of air contaminants which can trigger allergic reactions. These type of air filters use high-speed air to draw dust mites, dirt, mold spores, animal hair and pollen. But even with a HEPA filter at home, you should remember that contaminants can be found on countertops, furniture, drapes and in the nooks and crannies. Regular vacuuming and washing of rugs, curtains, pillowcases and mattresses should still be practiced.

It’s important to note that not all HEPA filters are created the equally. There are distinct differences when it comes to utilization and composition. Familiarize yourself with the different air purification technologies so you know what to expect and where to look.
