Key Features to Consider when Purchasing an Air Purifier
One of the main features you should consider when purchasing an air purifier is the size. To choose the best size for your needs, you must consider the size of the room you will be using it in, more specifically, the square footage.
To determine the square footage of a particular space, measure the length and the width and then multiply those measurements together. The specifications of each air purifier should indicate how big of a space they would work in.
Additionally, you should consider the air change per hour (ACH) rate. This number shows how often all of the air in a can be filtered. Generally, an air purifier should have an ACH rate of four or higher.
With any filtration device, maintenance is of the utmost importance. You have to remember to clean and change the filters to ensure that you are continuously receiving the best, purified air. Many air purifiers will notify you when they need to be cleaned via a light on the device.
This notification is important because while the manufacturer will give you a range when filters should be changed, environmental conditions can impact the life of the filters drastically.
If you are someone who will monitor the filter and other maintenance as the device ages, this feature may not be necessary, but it can be very helpful for the rest of us.
The ionizer feature of an air purifier helps clean the air because of the electrical effects of positive and negative charges. Positive and negative charges are attracted to each other.
With an ionizer, electricity is used to create electrons. These electrons then attach to air molecules and form negatively charged ions. These ions are then released into space and connect to positively charged smoke and other allergens in the air.
The filter of the air purifier can trap these larger particles more efficiently. Ionizers also can produce ozone, which can be harmful in high amounts.
It is important to look at the information provided with your air purifier to ensure that the product does not emit ozone at a rate of more than 50 ppb or parts per billion. This is the safest level of ozone, which will have no health impacts.
The purpose of an air purifier is to make your indoor space more livable, so a noisy machine will only detract from that goal. However, this concern will also depend upon where the air purifier will be located.
The noise may not bother you as much in the office as it would in your bedroom. To determine how loud an air purifier will be before you purchase it, look at the decibel level on the packaging. This is often shown as dB level. Quieter devices are generally in the range of 15 – 36 dB.
A device matching the sound of a refrigerator or lawn mower is between 50 and 90 dB. Some noises are considered too loud for people to live with consistently; generally, this is anything above 60 dB.
Installation and Maintenance Guide
Installing an air purifier is quite easy. Generally, all you need to do is remove the packaging around filters or the device and plug the unit in. The most important part of air purifier installation is placement.
Your air purifier can be rendered useless if placed incorrectly in your home. Generally, you want to put the unit in the area where you spend the bulk of your time, additionally take into consideration any areas of concern in your homes such as a smoker or pet.
The device should be placed somewhere where the front and sides are free of obstructions so that air can flow freely in and out of the unit. You also do not want to place the unit to high in the room or under a shelf, which will also inhibit the flow of air.
The maintenance needs of your air purifier depend upon the specific type of unit you have. It is important to read the manufacturer’s instructions and specifications prior to use.
Many air purifiers use disposable filters, which must be replaced regularly. Those that use permanent filters must be cleaned often. Depending on the filter, these can be cleaned by vacuuming or washing in warm soapy water. If washing the filter in water, be sure to rinse it thoroughly to remove any remnants of soap in the filter.
After the filter is rinsed, be sure that the filter is able to dry completely and carefully before replacing it in the air purifier. A wet filter can not only inhibit the efficacy of the air purifier, but it could create poorer air quality by releasing mold or mildew spores into your environment.
Frequently Asked Questions
What does CADR mean?
CADR stands for Clean Air Delivery Rate. This value indicates the volume of filtered air delivered from an air purifier. This measurement was established by the Association of Home Appliance Manufacturers (or AHAM) and has been in use since the 1980s. The faster the air purifier filters the air, the higher the CADR number.
What does ACH mean?
Air Changes per Hour, also known as ACH, tells us how often all of the air in a space is completely changed per hour. An ACH rating of four means that every fifteen minutes, or four times each hour, all of the air in the room or space is filtered.
To achieve healthy indoor air quality an ACH of five or six is recommended. However, for those with allergies or asthma, it may be best to err on the side of caution and go with an ACH rating around six or eight.
How do I know if I have poor air quality?
A good indicator of your indoor air quality is how you feel when you are at home. If the air is smelly or stuffy, you may have an air quality problem.
Additionally, if you make any changes around the house, such as remodeling or refurbishing, or if you move and you develop new health problems, air quality may be to blame.
Further, obvious sources of concern are smokers or pets. If you see condensation inside or have mildew or mold growth around your home, the air quality is likely concerning.
What is a micron?
A micron is a measurement used to convey the minute size of airborne particles. Micron is short for micrometer and is one-millionth of a meter. Airborne particles are often invisible to the naked eye, even though they can be harmful.
Dust mite allergens, for example, can be as small as .1 to .3 microns. As a comparison, a single strand of human hair typically measures from 30 to 120 microns.
As you can see, there are many air purifiers to choose from at a variety of price points with similar features. It is important to keep in mind your budget and your specific reasons for wanting an air purifier. For a large budget and a large space, the Rabbit Air Purifier may be the best option for you.
If you have a smaller space and want to spend less money, the Pure Enrichment Pure Zone 3-in-1 True HEPA Air Purifier may be a better choice.
If a quiet unit is what is most important, the Germ Guardian might be your best bet. Product four, the LEVOIT Air Purifier with True HEPA filter is the best air purifier for smoke under 100 dollars.
