When investing in an air purifier, you want to make sure that the one you choose can handle the myriad of toxins that affect our air quality. With rising pollution levels and rampant wildfires, not to mention the continuation of lockdowns worldwide, the quality of air in your home is now more important than ever. With so many purifiers out there claiming to instantly transform the air you breathe, it’s hard to know which purifier to choose. 

One sure way to obtain an air purifier that will deliver on its claims is to ensure that it has a high Clean Air Delivery Rate (CADR). This rating, independently provided by the Association of Home Appliance Manufacturers (AHAM), gives the clearest indication of how well an air purifier will perform. 

The CADR score is calculated by measuring the volume of clean air that is produced when a purifier is used against the three most common pollutants:

  • Dust
  • Pollen
  • Smoke

This score, therefore, allows you to make a confident and informed decision, knowing that a higher score means greater efficiency when removing harmful pollutants from your home or workplace.  

It’s important to remember that each purifier works differently in a given space, which is why we have included a diverse range of air purifiers that are suitable for different-sized rooms. This list includes purifiers ideal for your bedroom or office, such as the Levoit Core 300, to whole-house purifiers like IQAir’s GC MultiGas.

There’s something for everyone in this list, with purifiers across a range of budgets – although we ensured that each purifier came with an excellent CADR rating within its price range. As well as analyzing Consumer Reports to verify that real users of these air purifiers are satisfied with their efficiency. 

9 Best High CADR Air Purifiers: In-depth Review

1. LEVOIT Core 300

LEVOIT Air Purifier for Home Allergies and Pets Hair Smokers in Bedroom, H13 True HEPA Filter, 24db Filtration System Cleaner Odor Eliminators, Remove 99.97% Dust Smoke Mold Pollen, Core 300, White

The LEVOIT Air Purifier has a True HEPA filter that has three stages (pre-filter, True HEPA, and Activated Carbon filter). You can customize this purifier with other filters, like a pet allergy filter, mold and bacteria filter, or a toxin absorber filter system. It has a cylindrical design with a 360-degree intake grill, which is standard for most high-end purifiers. The purifier’s quality design makes it a very compact machine. Ideal places for this purifier include your desk or a shelf. It has the standard controls that most purifiers come with: fan speed, a timer, speed indicator, filter indicator, and a display lock.

The LEVOIT purifier has a CADR that generally ranges around 118 cfm. For dust, it has a rating of 140, 145 for smoke, and 141 for pollen. The fan power is of higher quality and doesn’t produce much noise. It uses Bionic Damping technology to keep the noise level to a minimum even on the highest setting. This purifier works best for those who have smaller rooms and are on a budget.

We recently produced a Levoit core 300 review, so be sure to check it out if this looks like an interesting option.

FAQs about High CADR Air Purifiers

What is CADR rating?

CADR stands for Clean Air Delivery Rate. This value shows you how many specific particles are removed from the air. CADR ratings indicate how quickly your purifier can clean the air. This is based on the size your purifier can cover. For example, a purifier with a CADR rating of 300 cfm will clean a room with less than 300 sq. ft faster than a purifier with a CADR rating of 200.

Who gives air purifiers their CADR rating?

CADR ratings come from the AHAM (Association of Home Appliance Manufacturers). This rating means that you are able to compare your purifier against another. However, it should be noted that the AHAM and CADR approval and rating are voluntary, so it’s not a mandatory program for air purifier manufacturers. Since 2010, California has required companies to be certified by the CARB. As of 2020, electronic in-duct air cleaning devices are required to have certification as well. To gain certification, air cleaners must be tested for electrical safety and ozone emissions. Ozone emissions must not reach a concentration limit of .05 parts per million (50 ppb).

To measure CADR ratings, three sizes of particles are measured. Each one indicates the purifier’s ability to remove smaller particles and larger particles. For example, a smoke CADR ranges between 0.09 to 1 micron. Dust CADR ranges from 0.5 to 3 microns. Pollen CADR ranges from 5 to 11 microns.

What air purifier filters are best for allergies and asthma?

Asthma and allergies are caused by pollutants in the air. Some you can see, which include pet hair, pet dander, dust, and smoke. However, there are many you can’t see which can also cause issues, like mold, odors, particles, viruses, bacteria, and VOCs. Air filters help to minimize these issues by removing these particles and bacteria from the air through the filters in the purifiers.

The best purifiers must have a True HEPA filter to remove small bacteria, viruses, and pollutants. An Activated Carbon filter also helps to remove smoke and odors. Ionizer filters should have an on/off feature to help prevent asthma attacks.

You don’t want an air purifier that makes tons of noise either. You want the noise level to be low or virtually none to avoid triggering asthma-related sound. The fan power your air purifier has is essential. The higher the fan power, the faster it can clean your room. ACH and CADR ratings help determine how powerful your fan is.

Which Air Purifier is Best for You?

An air purifier that has a higher CADR rating will help clean rooms faster and work to remove pollutants in the air. The most effective purifiers have a True HEPA filter, an Activated Carbon filter, high fan power, and low noise levels. You may have other qualities you’d want in an air purifier like Smart features or sensors that indicate air quality. Your room size will determine the CADR rating you should look for. For example, the bigger the room you have, the higher you’ll want the CADR. The price is something you may want to consider. We all have a budget and want to buy the best possible product we can for the best price.
