A mechanical air filtration system can remove particles of dust, animal dander and dust mites from the air you breathe at home or work, improving your comfort and health. Here's how the filters work:Basic air filtration systems consist of simple panels that cover the intake of furnaces or air vents. The most basic ones are made of fiberglass or polyester and allow air to pass through but trap large particles. Depending on the filter, it is meant to be either replaced or washed periodically.Though these basic filters are effective against dust, smoke and pollen, they don't work to trap harmful molds, bacteria or viruses, which are much smaller and can seep through. This is where High Efficiency Particulate Air (HEPA) filters can come in. HEPA filters more efficiently capture spores and viruses, filtering out nearly all airborne particulates. Despite one drawback -- motorized fans blow the air through HEPA filters, which can be a bit noisy -- they are the most widely used filters on the market.However, technology is advancing every day, and there are some filtration devices that approach HEPA filtration levels, but allow the filtration to happen without the fans and noise.

They've been featured on Extreme Makeover, as filtration devices used for people with hyper-sensitivity, allergies, or problematic lung and heart patients.Another option: UV filters, which can be combined with HEPA filters to make them even more efficient. HEPA filters catch the harmful pollutants in the air, but UV filters neutralize them. They release short-wave ultraviolet light that breaks down the particulates on a molecular level, altering their DNA and killing them.Air Assurance has been servicing the Broken Arrow and Tulsa region for over 30 years.
