What Is an Air Purifier?

You can open Table of Contents show

An air purifier, also known as an air cleaner, is designed to eliminate contaminants from the air in a room, thereby enhancing indoor air quality. These devices are often advertised as beneficial for individuals with allergies and asthma, as well as for reducing or eliminating second-hand tobacco smoke.

Commercially available air purifiers come in two forms: standalone units, which are small and portable, and larger units that can be connected to an air handler unit (AHU) or HVAC system. They find applications in medical, industrial, and commercial sectors. In industrial settings, air purifiers are utilized to remove impurities from the air before further processing. Techniques such as pressure swing adsorption or other adsorption methods are commonly employed for this purpose.

How Does an Air Purifiers Work?

An air purifier works by filtering the indoor air, removing various sources of pollution and pollutants. The process of air purification involves several steps. Firstly, the purifier draws in the air from the room, capturing particles in the process. Next, the air passes through multiple filters that trap different types of pollutants present in the air.

The effectiveness of an air purifier is determined by its performance, which dictates the volume of air it can treat based on the size of the room or area, such as bedrooms, living rooms, dining rooms, offices, common areas, or open spaces.

For optimal operation, it is crucial to have one air purifier per room. This approach ensures that each partitioned area receives adequate air purification.

What to Look for in an Air Purifier before purchasing?

Now let’s have a look at a few factors you should check before purchasing an air purifier. 

Filter Types: Choosing the Right Fit

Different filters excel at capturing specific pollutants, so selecting an air purifier with the appropriate filter is crucial. Here are the most common types of filters used in air purifiers:

HEPA Filters: Highly efficient at removing particulate matter (PM), such as pollen, mold, and dust. Ideal for those with allergies or asthma. Regular replacement is recommended.

Activated Carbon Filters: Effective in filtering smoke, odors, and volatile organic compounds (VOCs). Often used alongside HEPA filters for comprehensive purification. Replacement intervals vary, typically every three to six months.

Pre-filters: Capture larger debris and dirt. Some pre-filters are washable, providing cost-effective and eco-friendly options. Regular cleaning is necessary to maintain effectiveness.

Room Size: Matching Purifier to Space

Consider the square footage of the area you want to purify. Choosing an air purifier with an appropriate coverage area ensures optimal performance. Calculate the room’s square footage by multiplying its length and width.

Effectiveness: Clean Air Delivery Rates (CADR)

CADR measures an air purifier’s ability to produce purified air in cubic feet per minute (CFM). Higher CADR values indicate better performance. Ensure the purifier’s CADR matches your room size and desired pollutant removal requirements.

Noise: Striking the Right Balance

Excessive noise from an air purifier can be bothersome. Using a decibel meter, we measured the noise levels at both the lowest and highest settings. Most devices fall within the 20 to 60-decibel range.

Extra Features: Enhancing Convenience

While not directly related to air purification, additional features can enhance the user experience. Look out for:

  1. Wi-Fi Compatibility: Enables remote control via smartphone apps or smart home devices.
  2. Remote Control: Convenient control without needing to physically access the purifier.
  3. Filter Change Indicator: Alerts when it’s time to replace the filter.
  4. Air Quality Indicators: Provides real-time information on your home’s air quality.
  5. Multi-Function Air Purifiers: Combination devices that offer additional functions like humidifying or heating.

Certifications: Ensuring Quality and Safety

Certifications validate an air purifier’s performance, energy efficiency, and compliance with safety standards. Look for:

  1. Energy Star Certification: Meets energy-efficient specifications set by the Environmental Protection Agency.
  2. AHAM Verified Label: Indicates independent testing of CADR and claimed room size by the Association of Home Appliance Manufacturers.
  3. ETL Listed Mark: Confirms compliance with North American safety standards by Intertek’s Electrical Testing Laboratories.
  4. UL Listed Mark: Indicates compliance with safety standards by Underwriters Laboratory.
  5. Asthma & Allergy Friendly Certification: Ensures allergen reduction in the air, backed by the Asthma and Allergy Foundation of America (AAFA) and Allergy Standards Limited (ASL).

How We Tested the Purifiers?

Below let’s check how we’ve tested the air purifiers 

Testing Methodology

To ensure accurate and thorough results, we employed a comprehensive testing methodology that encompassed multiple factors.

Air Quality Testing Chambers

Creating controlled environments, we set up five indoor greenhouses referred to as “air quality testing chambers.” These chambers allowed us to evaluate each purifier’s effectiveness at cleaning the air.

Noise Levels

  • We used a decibel meter to measure the noise levels produced by each air purifier.
  • Measurements were taken in both the lowest and highest operating modes.

Setup Evaluation

  • We timed how long it took to set up each model and get it running out of the box.
  • Clearness of instructions played a significant role in our evaluation.

Design and Features

  • We assessed the design of each product, considering its placement in a home and its compatibility with typical home decor.
  • Additional features, such as smart capabilities, were taken into account when determining overall appeal.

Value Assessment

  • Our final evaluation involved assessing whether the results justified the price tag of each air purifier.
  • We considered the overall value based on a combination of performance and cost.

Testing Process

During our testing process, we systematically gathered reliable and accurate data on each air purifier’s performance.

Baseline Measurements

  • Prior to turning on each air purifier, we recorded baseline readings of air quality in the testing chambers.
  • Measurements included PM 2.5 (particulate matter less than or equal to 2.5 microns) and VOC (volatile organic compounds) levels.

Contaminant Release

  • To test air purification effectiveness, we released pet hair and lit an incense match in the zipped-up testing chambers.
  • The pet hair and incense allowed us to simulate common airborne pollutants.

Monitoring PM 2.5 Levels

  • At specific time intervals (5 and 10 minutes), we measured and recorded the PM 2.5 levels using both the air purifier (where applicable) and an air quality monitor.
  • This process was repeated for both the lowest and highest operating modes of each air purifier.

VOC Testing

  • For air purifiers designed to tackle VOCs, we placed mothballs in the testing chambers for 15 minutes.
  • Using an air quality monitor, we measured and recorded the VOC gas levels.
  • Similarly to PM 2.5 testing, we ran the air purifier for 10 minutes and recorded VOC levels at corresponding time intervals.

Extended Home Testing

After the initial controlled lab testing of 38 air purifiers, we conducted an extended home testing phase. This involved using each purifier in our own homes for six months to assess their performance in real-life settings. We paid close attention to their impact on day-to-day living and observed any long-term effects.

Refined Lab Testing

In our second iteration of lab testing, we introduced nine new air purifier models. This allowed us to dedicate more time to an even more sophisticated testing process. We continued to evaluate each model based on the same attributes highlighted earlier, while also introducing additional simulated air pollutants such as scented room spray and a mixture of sawdust, dirt, and flour.

Conclusion

That’s all about the best air purifiers in 2023

By understanding filter types, considering room size, evaluating effectiveness and noise levels, exploring extra features, and recognizing certifications, you can shop for air purifiers like a pro. Armed with this knowledge, you can find the perfect air purifier to create a healthier indoor environment for you and your loved ones.
