AHAM is the Association of Home Appliance Manufacturers. AHAM tests and rates the performance of room air purifiers to give consumers a good basis for comparing them. To make an informed purchase decision, consumers must know the air purifier’s clean air delivery rate (CADR) and the size of the room where the product will be used.

For optimum results the unit should be used constantly, with the doors and windows closed.

Please read the owner’s manual carefully, because only certain filter types can be washed.

Filter-washing process:

1. Unplug the unit from the socket.
2. Remove the filter.
3. Fill the sink with warm water and add a mild dish detergent.
4. Swish the filter around in the soapy water for about five minutes (do not leave the filter in the water longer than this).
5. Rinse with clean water for at least ten minutes to get all the soap out.
6. Shake excess water out of the filter.
7. Set on a towel to dry over night.
8. Once completely dry, place the filter back in the unit and plug the unit back in.

Make sure not to leave the filter in the water for too long. Also, make sure to only use mild dish soap, do not use any other chemicals or cleaners. DO NOT place a wet filter back in the unit, as this could damage the unit.

CADR, or clean air delivery rate, is the amount of cleaned air (measured in cubic feet per minute or CFM) that an air cleaner delivers to a room. A higher CADR indicates the greater ability to return clean air to the room.

Keep in mind that although airborne tobacco smoke particles will be picked up and removed by the air cleaner, some particles may cling to furniture, carpeting, drapery and the like. So even though the smoke particles in the air you breathe will be greatly reduced by the use of the air cleaner, you may continue to notice smoke odours from the build-up in the carpet, furniture or drapery.

The unit does not actually cool or heat the air, it only circulates it. However, when air blows on you it may make you feel cold. The only way to avoid this is to move the air cleaner farther away from you.

The specific ozone levels are not measured, but all our IFD units have ozone levels well within the limit of 50 ppb (parts per billion). In all studies and articles released about ozone-producing units, our units were never mentioned as being dangerous or harmful.

Your unit can give off odours if it has been stored for long periods, if there is a strong cooking odour, or if the filter is new. The best way to eliminate the odour is to run the unit outside on high for 1 hour. This will air out the filter and remove any odours. Remember, some odours cannot be removed, such as the odour of mildew after having been stored. In this case we recommend a new filter.

We commonly recommend changing the pre-filter every two to three months and the HEPA filter every two to three years. You can also tell it’s time to replace the pre-filter when you start to see a layer of gray dust form on the outside of the pre-filter. The HEPA filter should be replaced when the unit sounds louder then normal or when you get “pulsating” air.

• IFD units give the surrounding air a negative charge. The negatively-charged dust particles will then stick to the neutrally-charged collection filter.
• IFD units are about 98% as effective as a true HEPA unit.
• IFD units are in general quieter then than true HEPA units.
• IFD units normally use collection filters, meaning there is nothing to replace.
• IFD produces ozone as a by-product of the filtering process.

• True HEPA: A true HEPA filter is made of borosilicate material, which is densely-packed glass fibers. A true HEPA filter cannot be called true HEPA unless it achieves 99.97% efficiency on the cleanroom-grade D.O.P. (Dioctylphthalate) test. This is the definition of the filter.
• True HEPA units are generallymore efficient then IFD units.
• True HEPA units cover a larger area and have a higher rate of air changes per hour.

Air change refers to how many times the air in the room will cycle through the air purifier. The size of the room determines how many changes per hour the unit can perform when turned on high. The smaller the room, the more changes, the larger, the fewer changes.

HEPA stands for high efficiency particulate air. HEPA filters are the most efficient filters available. Honeywell true HEPA filters will capture 99.97% of all particles, .3 microns or larger, that pass through the filter.

For proper air flow and to make sure you don’t stain your walls or furniture, we recommend keeping the unit at least one metre from walls and furniture. This will ensure maximum efficiency.

It is not recommended to leave your windows or doors open. Having an open window or door will allow dirty air to constantly enter the room. Using an air purifier in a closed space ensures the maximum effect.

There is an internal circuit breaker which may have been tripped. You should unplug the unit and allow it to sit for about 12 hours. Then plug the unit back in to a working outlet and turn it on.

Bacteria and viruses cannot survive without water. Most particles that are captured from the air were riding on a particle of moisture. Once trapped in the filter, the moisture quickly evaporates and the bacteria and viruses die.
