MA-1 - Frequently Asked Questions


House Size and Coverage Area

The MA-1 air purifier is designed to completely filter a 3,000 sq.ft. house 24 times a day.

A 3,000 sq.ft. house with 8 ft. ceilings contains 24,000 cu.ft. of air. With its setting at speed 3 the MA-1 is able to process 350 cu.ft. per minute allowing it to entirely filter the air of your 3,000 sq.ft. house in 68 minutes (roughly once per hour).

3 Stages Filtration

MA-1 - 3 Stages FiltrationThe MA-1 is equipped with a 3 stage filtration system.

  • Stage 1: Carbon Prefilter
    Air is drawn in through a carbon pre-filter that removes large particles, such as dust, pollen and fibers.
  • Stage 2: HEPA Filter
    The finest particles including bacteria, attached viruses, mold, radon, smoke, and dust are captured by the main HEPA filter.
  • Stage 3: V.O.C. Filter (carbon trap)
    The volatile organic compounds (VOCs) present as gases, fumes, and odours are absorbed by the carbon trap.

Filter Replacement

  • Stage 1: Carbon Prefilter
    The prefilter prolongs the life of the HEPA filter. It removes the large dust particles before they enter the main HEPA filter. Replace the prefilter when it becomes covered with dust. It is recommended to replace the prefilter every 3 months.
  • Stage 2: HEPA Filter
    The HEPA filter needs to be replaced every 3 to 5 years depending on the environment in which it is used. For example, for smokers, it will last 3 years and for non-smokers, up to 5 years.
  • Stage 3: V.O.C. Filter
    The V.O.C. filter helps remove odor. It has to be replaced every 12 months.

We sell an annual replacement kit. Each kit contains 4 carbon pre-filter, 1 V.O.C. filter and a bottle of MicroGerm which is an anti-bacterial cleaning fluid.

Central vs Portable Usage

The HEPA Epurair system can be used in conjunction with a central heating system or an air exchanger. By operating it at full speed and connecting it to the existing central ductwork, you are assured air is purified throughout your home 24 hours 7 days.

Even if you bought the portable model, with the help of a special adapter you can convert it to be used in a centralized environment. Please phone us or ask your local representative.

The Epurair HEPA system was designed for continuous operation, 24 hours a day, 7 days a week. Although the system can be used on low speed, the high speed setting is recommended. This is especially true when you first use the unit.

The MA-1 system is modular. You can always convert it between the central and the portable applications. Please phone us or ask your local representative.

HEPA Efficiency

HEPA (High Efficiency Particulate Air) is a standard that was developed by the American Nuclear Energy Commission. HEPA filters are the world’s most efficient air filters. They are used in hospitals, pharmaceutical preparation and electronics manufacturing to eliminate very fine particulates. To be classified as a HEPA filter, the filter must eliminate 99.97% of all particles 0.3 microns in size.

Unfortunately many of the available HEPA filter on the market don't offer the efficiency that is required mainly due to the fact that it is difficult to maintain a leakproof seal around the HEPA filter and the frame of the unit..

Every MA-1 HEPA System is individually tested and analyzed for certification with a laser particle counter. This is why we are confident and proud to provide a certificate of effectiveness with every system. As a matter of fact we are the only manufacturer in the world to guarantee the 99.97% efficiency at the air exit of the unit. Others guarantee the efficiency of the HEPA media.
