Why would I buy an air purifier?
An air purifier filters common airborne particulate matter that may aggravate allergy symptoms, improving overall indoor air quality.
Where can I find indoor air pollution?
In a shower, kitchen or basement. On dusty furniture, dirty carpets, anywhere that someone smokes, uses household cleaners, or has pets.
What are the primary sources of air pollution?
- Tobacco smoke – is one of the smallest allergens. 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.
- Mould 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.
Some people feel personally concerned about indoor air quality and many understand the causes of it. But now, you need to do the right things to combat it.
How does an air purifier work?
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 odours and captures larger particles. Next, the air passes through the HEPA, or main filter. Some units have electronic ionisers to further assist in particle removal. A powerful fan quietly distributes air throughout the room.
How is air cleaner performance measured?
CADR, or Clean Air Delivery Rate, is a regulated standard for air purifier performance, and also determines recommended room size. CADR evaluates smoke, dust and pollen particulate.
How big is a micron?
A micron is approximately 1/300th the diameter of a human hair.
What particulates does an air purifier filter?
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.
What does the carbon filter do?
The carbon filter helps reduce odours, such as smoking or cooking odours, and helps capture large airborne particulate.
What contributes to poor indoor air quality?
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.
What room sizes can an air purifier clean?
Most air cleaners also have appropriate room size reference on the front of the packaging. All room size recommendations are based on AHAM test results.
They can vary from 1.83 m x 2.74 to 6 m x 7.32 m (6’ x 9’ to 20’ x 24’).
What is an ioniser?
Some Air Purifiers have an independently controlled ioniser, 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 colourless, odourless and completely harmless. Negative ions help the air purification process by attaching themselves to very small airborne particles in the room.
How does an ioniser work?
These particles take on a negative charge and may join with positively charged particles such as dust, pollen, smoke and pet dander to form larger particles that are then more readily captured by the filter system, or may be attracted to positively charged surfaces throughout the home, like walls or floors.
This may occur more frequently when the filter is nearing the end of its functional life expectancy and is able to capture less of the charged particles. You may also note after extended use, that dust may have collected around the grills or front panel.
This is from the ionisation 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 ioniser 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. Using the ioniser in conjunction with dirty filters may result in dirty particles exiting the air purifier and being attracted to walls, carpets, furniture or other household objects. These dirty particles may prove very difficult to remove. Homes with excessive amounts of pet dander, dust, or smoke may decrease the life expectancy of the HEPA filtration system.
What is a HEPA filter?
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.
What is a carbon Filter?
The carbon filter is used as a pre filter to trap large particles. The carbon filter also helps in the reduction of room odours.
What is an electrostatic Filter?
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.
What is a washable foam filter?
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.
How often do I need to replace my filter(s)?
The carbon filter needs to be replaced every 3-6 months depending on usage, while the HEPA filter needs to be replaced every 3-4 months depending on usage.
Does my unit have a filter condition monitor?
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.
How do I clean my air cleaner?
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.
What should I do if my air cleaner won't operate?
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.
What should I do if I notice decreased air flow?
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.
How do I store my air cleaner?
Remove all filters before storage, as carbon filters will continue to absorb odours though the unit is not in operation, then store in a cool, dry location.
