These devices are available in the stand alone models which are in small size and affixed air purifying units which are usually bigger. Normally, this type of device was popular only in the hospitals and industrial units, but now they are manufactured for the domestic purposes also.
HEPA air purifiers are widely popular in the industrial units and factories where there is a release of radioactive radiation. They are also responsible for reducing the concentration of allergens and soot particles which are released from the conventional stove.

There are many air purifiers which have pre filters attached to them so that most of the air particles are stopped at the first filter.
