NQ Air Purifiers

NQ has historically made purifiers for medical and military applications but now has a portable model for the home called the Clarifier.  Replacement filters are costly but in line with high end units.  The Clarifier also uses ultraviolet lamps designed to target bacteria, fungi, molds, and viruses.

NQ Industries Company Info

Since 1993, NQ Industries has been manufacturing air filtration and air sterilization devices, utilizing UVGI (ultraviolet germicidal irradiation), HEPA (high efficiency particulate air) filtration, UVPCO (ultraviolet photo catalytic oxidation) and activated carbon filtration technologies.

The company began as a supplier of tuberculosis isolation units to hospitals and homeless shelters. NQ’s primary product lines are still targeted to medical care facilities, but the company has branched out into military and food industry applications as well, and the company also makes air treatment systems for commercial and residential use.

In isolation rooms, operating theaters, and other hospital setting, air purity is of critical importance. Today NQ’s air treatment systems are used in over 370 healthcare facilities in 37 states, as well as by U.S. armed forces (Army, Navy and Air Force) and numerous school facilities throughout the nation. NQ products have a strong international following as well, and in 2003 the company donated several air purifiers to help combat the SARS (severe acute respiratory syndrome) outbreak in Hong Kong.

Air Purifier and Sterilizer Price Range

NQ’s filtration and sterilization devices are standalone products designed to be utilized around the clock, 365 days a year. NQ sells its products through a comprehensive network of dealers. List price for the basic Clarifier-Standard NQ Industries Air Purifier, designed to be used in the home, is slightly more than $900, but dealers frequently give discounts of over 20%.

While the majority of air purifiers manufactured today are made overseas, all components used in NQ products – with the exception of the blower – are manufactured in the United States from American produced steel. NQ Industries eschews the use of plastics in its products in order to guarantee that its customers receive the cleanest air possible.

NQ Air Purifier Technology

Each NQ product is designed to accommodate a slightly different process, but generally all of them work by trapping particles larger than 10 microns in size with pre-filters. Then air is circulated through some combination of specialized filters like activated charcoal or HEPA filters to remove odors, volatile organic compounds and other chemicals, and particulates as small as 0.3 microns. Finally air is circulated into a specialized chamber where UVGI is used to destroy biological contaminants such as bacteria, viruses, fungi, and mold. Purified air is then discharged back into the room.

Most air purifiers that deploy UVGI technology use it only on the surface. NQ Industries pioneered the use of the single pass UVGI kill chamber.


NQ Air Purifier Models

NQ Industries manufactures five core products, in addition to replacement filters, replacement lights and other product accessories.

  • NQ Clarifier Standard: The NQ Clarifier Standard air purifier removes indoor pollutants such as dust, dander, bacteria, mold, and viruses through a two-fold process: first, particles down to 0.3 microns in size are filtered out by a medical-grade H13 HEPA filter; next biological contaminants such as bacteria, viruses, fungi, and mold are destroyed by UVGI decontamination.
  • NQ Clarifier Medical: The NQ Clarifier Medical removes hazardous biological contaminants such as particulates, bacteria, gases, viruses and odors through four-stage filtration technology that includes a medical-grade HEPA filter, 15 pounds of activated carbon, post filter, pre-filter, and four UV lamps. A modified version of this model, the NQ Clarifier Medical Plus, uses a five-stage process and is effective in areas of up to 1,500 square feet.
  • NQ 250 – 400: The NQ 250 – 400 is a wall-mounted air purification that uses a high efficiency 99.97% HEPA filter and UVGI decontamination to destroy bacteria, viruses, fungi and molds.
  • NQ 360 – 720: The NQ 360 – 720 is a ceiling-mounted air purification unit that filters particles down to 0.3 microns in size as well UVGI decontamination.
