We think carefully about what we put into our bodies. That should include the air we breathe, no?
It’s easy to forget when scrubbing your floors and polishing your surfaces that it’s equally important to clean the air circulating around your living space. Dust, pollen, mold, and other allergens exist in the air we breathe every day. Just because they’re invisible doesn’t mean they’re not there.
Choosing the best air purifier to suit your lifestyle is vital to ensuring good health and the cleanliness of your home. With our help, you won’t have to go outside for a breath of fresh air!

Finding the Best Air Purifier
Selecting an air purifier that’s safe and effective may seem like a daunting task. But fear not, we’ve got you covered! We’ve saved you the hard work of finding the right air purifier by compiling the best ones for every kind of toxin that could be contaminating your air.
Let’s help you choose an air purifier that matches your way of living, falls within your budget, and doesn’t dominate your space.
Some of you might be wondering what an air purifier even is. Is it worth spending money on something that will just sit quietly in the corner of your room?
Air purifiers are good for your health (kind of like vegetables, but you don’t have to eat your purifier). They remove airborne particles of dust and mites, mold, allergens, smoke from your indoor air. Besides these, they also get rid of other nasty microscopic pieces you might be unknowingly inhaling (1).
For instance, if you or someone in your household is prone to getting sick, an air purifier may be a good investment. These can trap bacteria and viruses that cause illness.
Types of Air Purifiers
There are various types of air purifiers to choose from:
Ultraviolet Air Purifiers
UV air purifiers remove harmful viruses, bacteria and pathogens from the air using ultraviolet light (2). They can remove 99 percent of microorganisms present in the air, such as mold spores.
This type of air purifier is inspired by the medical use of UV light in hospitals to disinfect laboratories and patient rooms.
- Kill germs, viruses, bacteria and mold, which cause illness.
- Less maintenance than filters.
- Use less electricity compared to other purifying systems.
- Bulbs need to be replaced every so often, depending on the frequency of use.
- Dust can decrease the efficiency of bulbs.
HEPA Air Purifiers
HEPA (high-efficiency particulate air) air purifiers are equipped with a dense HEPA filter.
It traps up to 99.99 percent of particles (over 0.3 microns) in the air.
These include pollen, dust, and mold (3).
- Effective in removing almost all air pollutants.
- Captures both small and large particles.
- Good for people who suffer from asthma or allergies.
- HEPA air filters must be replaced monthly.
- Ineffective at trapping viruses and bacteria.
- Incapable of neutralizing odors.
Activated Carbon Air Purifiers
Activated carbon air purifiers are good at removing smoke, odors, and fumes from the air by trapping molecules of gas in a bed of activated carbon or charcoal (4). They are designed to tackle volatile organic compounds (VOCs). Some will also work alongside HEPA filters that will remove other particles from the air.
- Effectively remove odors, smoke, and other chemicals in the air.
- Particularly useful for those sensitive to smells.
- Ineffective for the elimination of pollen, dust, and mold.
Ionic Air Purifiers
Ionic air purifiers use ionization to combat contaminants in the air. They release negative ions that attach to airborne particles through electrostatic attraction. This process makes the particles heavy so they drop out of the air.
Ionic air purifiers function without a motor.
- Very quiet.
- Able to remove anything (except odors) from the air.
- Generate ozone, which is potentially harmful.
- You must clean more often to remove dust particles that have fallen from the air.
Electronic Air Cleaners
Electronic air cleaners are equipped with HEPA filters and positively charged ions. These work with your air conditioner to remove almost all allergens in the air.
Electronic cleaners ensure that the air that travels through your home’s HVAC system passes through filters, which trap larger particles. The smaller particles are then caught by electrically charged filters, which prevent them from circulating in your home.
- Effectively remove dust, bacteria, viruses, fumes, and smoke from the air.
- Able to catch the smallest of particles.
- Straightforward cleaning process, as collector cells can be hand-washed or placed in your dishwasher.
- Require professional installation.
- Collector cells need to be cleaned monthly.
- Filters must be replaced monthly.
Central Air Cleaners
Central air purifiers can be connected to your central heating or cooling system to purify your air circulation.
They work within the air ducts of your home to remove particles, such as dust and pollen, smaller than 1 micron.
- Very quiet.
- Efficient at removing small particles such as pollen and dust.
- Limit the impact of allergies and viruses on your health.
- Extend your air conditioner’s lifespan by filtering out particles that affect its functionality.
- Require professional installation.
- Costly.
Air-To-Air Exchangers
Air-to-air exchangers provide ventilation throughout your home by replacing stale air with fresh air. They use energy recovery ventilators (5). This means that, for instance, in cold weather, the air-to-air exchanger will trap heat in the air. Whereas, during warmer seasons, the air-to-air exchanger will cool the clean outside air entering your home.
- Regulate temperature and humidity.
- Reduce the presence of mold in the air.
- Expensive.
Choosing Your Air Purifier
Here’s a list of the prime features to look out for when choosing an effective, high-quality air purifier that’s right for you:
True HEPA Filter
Catches 99.97 percent of the smallest particles in the air, including dust, pollen and pet dander (6).
Reusable Pre-filters
Trap large particles in the air and prolong the primary filter’s lifespan in your air purifier. They also provide convenience as they can be washed, allowing you to save money on replacement filters.
UV Light
Eliminates bacteria, viruses and germs which cause illness, helping to create a clean and sterile living space.
Filter Change Indicator
Means you don’t have to guess when the filter in your air purifier needs to be changed; the indicator will tell you.
Air Quality Sensor
Allows for a ‘hands-free’ system, as it regulates the quality of the air by identifying toxins. Then it automatically adjusts the fan speed to eliminate them quickly and subsequently restores its regular operation.
Energy Star Label
Distinguishes air purifiers that are environmentally friendly, have low operating costs and greater efficiency levels.
Remote Control
Provides an element of convenience. Air purifiers with a remote control feature allow you to control the settings from anywhere in the room. You no longer have to fiddle around with the buttons on the purifier itself.

Air Purifier FAQs
How Do I Detect An Indoor Air Quality Problem?
It may be difficult to identify an indoor air quality problem. However, there are few small signs which can mean big things when it comes to your air quality.
Pay close attention to your allergies. Note the appearance of new symptoms, such as coughing or sneezing. If you frequently suffer from bronchitis or pneumonia, it may be a result of pollutants contaminating your indoor air.
Consider your external environment. Is there is construction happening near you? Or has there been a fire nearby? Residual smoke and dust can contaminate your indoor air quality (11).
How Can You Improve Indoor Air Quality?
Besides investing in an air purifier, there are several things you can do to improve the air quality in your home.
- Change your air conditioning filter regularly, especially if you live in a polluted area.
- Use cooking vents in your kitchen to limit fumes and odors.
- Clean as often as you can and vacuum your rugs and carpets regularly to limit the accumulation of dust around your furniture.
- Allow fresh air in whenever possible (12).
What Are CADR Ratings?
CADR stands for Clean Air Delivery Rate. The higher the CADR rating of an air purifier in cubic feet per minute, the more air it cleans. Different particle sizes (smoke, pollen and dust) should be given their own rating.
You can use CADR ratings to compare the performance of different air purifiers. It indicates how fast an air purifier can clean the air in a particular room.
Do Larger Air Purifiers Have Better CADR Ratings?
The size of the air purifier may not always determine its CADR rating. High CADR ratings come from an air purifier’s high fan power, filter surface area, and ability to cover the air in a large space.
Where Should I Place My Air Purifier?
Small air purifiers are handy as they can be moved from room to room as needed. When deciding where to place your air purifier, choose the room(s) you spend the most time in. It may also be wise to choose room(s) you think are most affected by air pollutants.
The ideal location for an air purifier is in the middle of a room, with no objects blocking it and preventing the air from reaching it. However, this may cause a tripping hazard. So try to aim for at least 3 feet of space between the device and a wall or piece of furniture (13).
Our Final Breath
Air purifiers get rid of nasty toxins lingering in the air we breathe. On the hunt for one to improve indoor air quality and contribute positively to your health? Look out for air purifiers with HEPA filters that trap the tiniest of harmful particles.
Whatever your lifestyle, there’s an air purifier for you. When making your selection, it’s worth considering a purifier with an air quality sensor. A filter-change indicator and reusable pre-filters which make cleaning easier and more convenient are also crucial.
We also care about the environment, so keep an eye out for that Energy Star label. With the best air purifiers, you’ll breathe a little easier knowing that your air is clean and toxin-free!
