  • What is an Electret?

    Electret is a counter term of magnet. A magnet is a ferrous material that possesses a quasi-permanent internal and external magnetic field. An electret is a dielectric material that possesses a quasi-permanent internal and external electric field. There are natural electrets such as quartz and biomaterials. Artificial electrets are made by polarization, penetration of ion and electron beams, ...

  • Why choose an electrostatic, washable air filter?

    When deciding what type of air conditioner or furnace filter to use, you should keep two things in mind: Airflow and Efficiency. In order to work at its optimum level, the a/c or heating unit requires no restriction to air flow. You should choose a filter that has the least effect on airflow, but removes the most dust from the air. ACI’s electrostatic air filters allow the air conditioning ...

  • Calculating pressure drop of nanofiber air filter media

    Nanofibers are becoming an integral part of many advanced air filtration media thanks to their enormous specific surface area. The large surface area, however, can cause strong resistance against fluid motion, which leads to an increase in pressure drop. Pressure drop caused by fibrous media has been the focus of many pioneering studies in the past, resulting in analytical or empirical ...

  • Application of an Enzyme-Linked Immunosorbent Assay for the Analysis of Paraquat in Human-Exposure Samples

    Paraquat is a toxic quaternary ammonium compound used as an herbicide around the world. Easy, fast, and inexpensive but sensitive methods are needed to study the effects of long-term, low-level exposure of paraquat on human health. An enzyme-linked immunosorbent assay (ELISA) was used for quantification of paraquat in urine and air-filter samples collected in a human-exposure study among farm ...

  • Cigarette smoke: size distribution and effects on filters

    Cigarette smoke is an important aerosol in the air filtration industry and research. It is an unwanted aerosol and therefore there are many applications for air filtration (ex. cigarette filters, residential and commercial ventilation filters, home air cleaners). Cigarette smoke is especially important to air filter performance for several reasons. First, the size of cigarette smoke particles ...

  • How To Compare Commercial Ride On Mowers

    There are plenty of professions that would require the use of a commercial ride on mower – perhaps you work for a gardening or landscaping company that looks after private properties or perhaps you work for a council and are in charge of maintaining local parks. For whatever reason, choosing an appropriate mower for your needs should be your main focus otherwise you are setting yourself up ...

  • Monitoring Air Makes Sense

    Did you know that air filters were originally put in air handling systems to protect the life of the equipment, not human life? And that it is not uncommon for air filters to get changed less frequently to save on maintenance costs? Monitoring input from sensors can tell operators when filters and media need changing. We have required food labels that list all ingredients. Why not electronic ...

  • How to Choose the Right Commercial Air Filter

    When it comes to selecting a commercial air filter, or air filtration system, there are many variables that have to be considered. In general, the choice of which air filter can be made a bit easier by first defining the overall goal that you are trying to achieve which is usually one of two options. Is the purpose of the filter to protect the air circulation equipment, or is it to provide a ...

  • Suffer from Allergies or Asthma?

    The “ULTRA” washable air filters have an antimicrobial protection that will not allow bacteria, fungi or mold to grow on the filter surface. The antimicrobial protection is not a coating and is not sprayed on. It is a safe and effective antimicrobial agent processed directly into the electrostatic fiber media, rendering it as permanent as the filter itself. The University of ...
