This model will efficiently remove a high degree of particles and allergens from the air. These include mould spores, dust, pet dander, smoke and dust.
The carbon pre-filter will minimise odours and tobacco smoke in the atmosphere.
The AP-15A will clean a room up to 10.6m² at 4.8 times per hour, assuming that the unit is on high speed in a closed room. Alternatively, a room of 16m²will be cleaned at 3 changes per hour. This is due to the fact that we recommend air purifiers on a minimum of 3 changes per hour, which is sufficient to benefit from cleaner air.
The change filter indicator will let you know when it is time replace either the carbon filter or the True HEPA filter. HoMedics recommend replacing the carbon pre-filter every 3 months under normal usage conditions and they recommend changing the True HEPA Filter every 12 months under normal usage conditions. The indicator is based on hours of use, not the intensity of atmospheric allergens.
HoMedics are hard working machines and the three speeds will allow you to respond to the atmosphere. You may want to adjust to a higher speed if pollen is particularly high or if air pollution spikes. Working at a medium level continually should be optimal for clean air under normal usage conditions.
