Why Use a HEPA Filter?

For mold illness patients, using a HEPA filter to clean the air is an important step in keeping your environment safe.  These filters are able to remove 99.97% of extremely small particles that are 0.3 microns.  This is very important since there are far more tiny mold fragments than whole mold spores floating around in the air.  The use of UV light or ozone is unnecessary since dead mold spores and mold spore particulates can be just as detrimental to your health as live mold spores.  Ideally, we need to remove these spores and particulates from the air instead of just killing them.

Choosing the Right HEPA Filter

In order to choose the right HEPA unit for you, it is necessary to know the square footage of your house.  Depending on the size and layout of your house, you may need to purchase more than one unit in order to get adequate coverage for all areas of your home.  Because of the way air flows and the fact that the rate of flow is reduced in the corners of the room compared to the middle of the room, Dr. Shoemaker recommends that you purchase portable units that can be easily moved around the room each day and also from room to room.  This helps ensure that you are adequately cleaning all of the air in your home.  The amount of air that the unit can clean is also dependent on the fan speed that you choose.  Higher fan speeds result in more noise but are also able to clean the greatest amount of air.  Also be sure that you choose a unit that has an actual HEPA filter and not a HEPA-like or HEPA-type filter.  An actual HEPA filter is made to filter smaller particles with an extremely high degree of efficiency.  Be sure the unit you choose removes 99.97% of particles 0.3 microns in size.

When choosing which model is right for you, keep in mind that filter replacements can be a considerable long-term expense.  Although a unit might initially cost less up front, it might end up costing more in the long run depending on how often the filter needs to be changed.  Also don’t forget to protect your new HEPA filter and other electronic equipment from damage by always using a surge protector.
