What an Air Purifiers Does
In simple terms, an air purifier is a device that’s been specially designed to remove harmful particles and toxins from the air. This creates a cleaner airspace around you and provides fresher air for you to breathe.
Depending on the kind of air purifier you buy will determine which type of contaminants it can remove from the air. Examples of this include dust, pollen, mold, fungi, pet dander, smoke, viruses and bacteria.
To find out more about how an air purifier works and how can you improve indoor air quality, take a look at our section on what air purifiers can do for you.
Key Features to Look for
When looking for an air purifier for your home, you’ll notice that certain features keep popping up – elements that manufacturers highlight in order to get you to buy their product.
When you’re comparing two or more air purifying devices there are really only a few key features you should care about. Anything else a product promotes is most likely just marketing hype to make a sale and you shouldn’t worry about it.
Read below to find out which options actually matter for when you’re buying an air purifier.
Air Filtering Types
Here’s something you may not know: Every air purifier is designed to work best with with a specific type of filter. Each of these filters are manufactured to get rid of certain types of particles.
Some air purifiers may feature only one type of filter, while others may contain a combination of two or more. When looking for the right air purifier for your home, it’s important for you to know which kind of particles each filter is best at removing. Then, you’ll know what product is best for your specific needs.
1. HEPA Filter
One of the most common filter types you’ll come across when looking for an air purifier is a HEPA filter. HEPA stands for High Efficiency Particulate Air. This type of filter is rated to capture 99.97% of harmful particles from the air. For this reason, it’s the most highly recommended type of air purifier by doctors and allergists. It gets rid of most allergens and dust particles that cause breathing problems.
Devices that use this type of air filtering go by the name “Ionizer.” It works by sending out negatively charged ions into the air that attach to positively charged particles like dust and other common allergens. Once this bond is made, these particles become very heavy and can’t remain in the air. Therefore, they fall to the ground and don’t enter into your lungs when breathing.
3. UV Light and Activated Carbon Filters
A UV light is a unique type of air purifying technology because it actually kills harmful bacteria, viruses and other pathogens that make you sick. An Activated Carbon Filter is the only kind of filter that removes particles from the air that cause smells and odors. It’s highly efficient at getting rid of odors created by chemicals, mold, smoke, gases, paints, pets and other contributing factors around the house.
Other Things You Should Consider
Below, are some additional things you should consider when looking for the best air purifier for your home. Keep these features in mind as you’re comparing different products.
Of all of the specifications related to air purifiers, the CADR rating is the most important. Why? Because, it tells you how well the product actually cleanses the air.
CADR stands for Clean Air Delivery Rate. This rating is calculated by the Association of Home Appliance Manufacturers (AHAM) and it stamps its certification only on those products that meet a specific criteria.
What you’ll find on these types of devices is a scientifically backed set of numbers that tells you exactly how effective an air purifying product is against removing dust, pollen and tobacco smoke. If a device doesn’t include this certification, it’s anyone’s best guess how effective the air purifier really is purifying the air around you.
The ACH rating stands for Air Changes Per Hour Rating. This specification is important because it tells you how often the air is exchanged each hour by the device.
For example, an ACH rating of 7x means that the air is filtered 7 times per hour within a room. An easy rule to remember is that the higher the number, the better the product operates. The lower the number, the less efficient it is at purifying the air inside the room.
If you’d like to learn more about this rating, check out our dedicated article on the ACH Rating here.
Another important aspect to consider when buying an air purifier is to find out what the maximum space coverage it can purify.
Every air purifying product is designed to purify a space up to a certain amount of square footage. This number is crucial because if you don’t account for it you’ll be wasting your money.
For example, if a product that’s rated to purify a space up to 200 sq. ft. is put inside a room that’s 400 sq. ft. in size, it’s a waste of money because it can’t handle that large of an air space. On the other hand, if a device can purify a room up to 400 sq. ft. and it’s placed inside a room that is only 200 sq. ft. in size, you’re using a product that’s too powerful for the room and you’re wasting money on a larger electricity bill.

When comparing air purifiers, it’s always good to take note if a product includes the Energy Star certification or not. This label provides you with assurance that the device not only uses the least energy possible, but also doesn’t waste your money on higher electric bills.
We recommend that you always choose an air purifier that includes this certification. Without it, you’ll never know much energy it uses per month to operate. For additional information, visit the link above to find out why the Energy Star label is important for an air purifier.
