Air Purifiers

Care & Usage

Remove all filters before storage, as carbon filters will continue to absorb odors though the unit is not in operation. Then store in a cool, dry location.
Always turn the unit off and unplug before cleaning. Once unplugged, use a soft, damp cloth and a non-abrasive cleaner (optional) to wipe the grill area and outside of the unit clean.
Most of our models include a filter indicator to take the guesswork out of filter replacement. Please see the owner’s manual for specific operation of this feature.
To check if the nightlight is on, cover the sensor with your finger and/or make sure the room is dark. Push the light bulb icon to turn the nightlight on or off. The sensor may be blocked, make sure there is nothing resting on the control panel that may be covering the sensor. The sensor may be dusty or dirty, simply wipe the sensor clean with a soft cloth.
Check to make sure nothing is blocking the air inlet. If there is nothing obstructing the inlet and there is decreased air flow, the HEPA or carbon filters may need to be changed. Check filter condition and replace if necessary.
Check to make sure the unit is plugged in and the electrical outlet (or circuit breaker) is working properly. Make sure the unit is turned on by pressing an operating speed button. If the door is ajar the unit will not operate. Make sure the filters are properly installed and firmly close the door.

Filters

ULPA, also known as Ultra-HEPA, filters are designed to trap up to 99.999% of all airborne particles 0.3 microns or smaller from the air that passes through the filter. These include tobacco smoke, household dust, and pollen.
The carbon filter is used as a pre filter to trap large particles. The carbon filter also helps in the reduction of room odors.
The carbon filter needs to be replaced every 3-6 months depending on usage, while the HEPA filter needs to be replaced every 12-18 months depending on usage.
The carbon filter helps reduce odors, such as smoking or cooking odors, and helps capture large airborne particulate.
Electrostatic filters use static electricity. They have a static charge, which causes airborne particles to cling to the filter, just like static charged clothing sticks together.
Washable foam helps capture larger particles and can be easily cleaned. Simply remove the foam filter from your machine and wash it in warm, soapy water. Rinse and drip-dry the foam thoroughly before replacing it.
HEPA stands for High Efficiency Particulate Air. These filters are designed to remove up to 99.97% of all airborne pollutants 0.3 microns or larger from the air that passes through the filter. These include tobacco smoke, household dust, and pollen.

General Information

A micron is approximately 1/300th the diameter of a human hair.
An air purifier filters common airborne particulate that may aggravate allergy and asthma symptoms, and improve overall indoor air quality.
Dirty air is drawn into the air purifier through the inlet grill. The pre-filter traps larger airborne particles. Air then passes through a carbon filter, which helps reduce odors and captures larger particles. Next, the air passes through the HEPA, or main filter. Some units have electronic ionizers to further assist in particle removal. A powerful fan quietly distributes air throughout the room.
Most air purifiers are tested for efficiency in terms of Clean Air Delivery Rate (CADR). These ratings indicate the volume of filtered air delivered by an air purifier, allowing you to compare one air purifier to another. The higher the CADR number, the faster the unit filters the air.
  • Tobacco smoke – is one of the smallest allergens, and for years the Environmental Protection Agency (EPA) has reported the link between second-hand smoke and negative health effects.
  • Pollen – It comes from trees, flowers and grass, and even opening a door can allow millions of these particles into a home. Some people are particularly sensitive to the presences of certain pollen particles.
  • Animal dander and saliva – People who are allergic to cats and dogs are actually allergic to the dander flakes their pets shed. Dander can remain in a home long after the presence of the host animal. Also, the protein found in animal saliva is the most allergenic part of an animal. Both animal dander and saliva can be found in carpeting, bedding and on the furniture – basically anywhere your pet has been.
  • Mold and mildew – Typically found in the shower, kitchen or basement, these sneaky plant spores also grow any place that’s warm and humid.
  • Dust - A combination of bacteria, atmospheric debris (mainly invisible) and other airborne particles (visible to the naked eye). Although not always detectable by the eye or nose, many of these air pollutants create a hazardous environment, which negatively affects the air you breathe and can aggravate and instigate allergy symptoms.
Today’s energy efficient homes are built to hold air inside, avoiding heat loss in the winter and heat gain in the summer. Of course, what’s better for your energy bills isn’t necessarily better for indoor air quality. This type of tight construction doesn’t allow the home to breathe. Opening a window isn’t always the answer either. That’s when an air cleaner can help, especially if someone in your home suffers from allergies.
Some Air Purifiers have an independently controlled ionizer, which, when turned on, releases negative ions into outgoing filtered air. Ions are tiny particles that carry a positive or negative charge. These ions exist naturally around us, in the air, water and ground. Both positive and negative ions are colorless, odorless and completely harmless. Negative ions help the air purification process by attaching themselves to very small airborne particles in the room. You may also note after extended use, that dust may have collected around the grills or front panel. This is from the ionization affect caused by the negative ions exiting from the air outlet. This is additional evidence of the air cleaning effectiveness of negative ions. The dust can be easily removed with a clean, damp cloth or soft brush. Finally, using your ionizer may result in an occasional popping or cracking sound. This is a normal sound, generally caused by particles of dust that are interrupting the flow of ions, causing a small build-up of ions that, when discharged, cause the popping or cracking sound. NOTE: It is important to replace the HEPA filter at the recommended intervals in order to maintain optional air quality.
Depending on the filter, an air purifier filters dust, smoke, pollen, pet dander, mould spores, and other airborne particulate as small as 0.3 microns.
The room size is generally recommended based on unit's performance ratings (CADR). Most air purifiers would have the appropriate room size reference on the front of the packaging. They can vary from 6ft x 9ft to 20ft x 24ft.
In a shower, kitchen or basement, on dusty furniture, dirty carpets, tobacco smoke, household cleaners, and in areas frequented by your pets.
