Trans Fats or Hydrogenated Fats. Trans fats are actually unsaturated fats, but they can raise total and LDL (bad) cholesterol levels while also lowering HDL (good) cholesterol levels. Trans fats are used to extend the shelf life of processed foods, typically cookies, cakes, fries and donuts.rans Fats or Hydrogenated Fats.

High-efficiency particulate arrestance (HEPA), also sometimes called high-efficiency particulate arresting or high-efficiency particulate air, is a type of air filter.
HEPA Vacuum Manufacturers. I don't really advocate the use of vacuum cleaners to pick up lead dust, although I am told it is safe. Conventional filters are absolutely a no-no as the lead dust can pass right through those and be blasted back into the air via the vacuum exhaust port.To stop lead dust inside a vacuum, you need a special filter known as a HEPA filter.HEPA is an acronym for high performance particulate air. These filters are expensive but they can trap very, very small particles that are invisible to the eye.ost of the ordinary wet / dry vacuum companies make a vacuum cleaner that can be equipped with such a filter. I own a Ridgid brand wet / dry vacuum that can handle such a HEPA filter. I am reasonably confident that the following vacuum manufacturers have certain models that can be equipped with a HEPA filter.
