There are some detailed factors may you don't know when seeing the table:
- Coverage Area (sq. ft.): The area that the air purifier can effectively clean in square feet.
- CADR (CFM): The Clean Air Delivery Rate measures the air purifier's ability to remove pollutants from the air. A higher CADR means the air purifier can clean the air more effectively.
- Filters: The number and type of filters used by the air purifier.
- Noise Level (dB): The noise level of the air purifier in decibels. A lower number means the air purifier is quieter.
- Energy Consumption (W): The amount of energy the air purifier uses in watts. A lower number means the air purifier is more energy-efficient.
Do Air Purifiers Really Work?
The effectiveness of air purifiers is a topic of much debate, but the answer is a resounding yes. After years of testing and using various air purifiers, it has been proven that they do indeed work. The first signs of improvement in air quality can be noticed within a few days of use, and after 1-2 weeks, the pre-filter will show visible dust deposits. This is a clear indication that the air purifier is doing its job and removing pollutants from the air.
How We Tested the Air Purifiers
As testers at RetailCoupons, my team and I take a comprehensive approach to evaluating air purifiers. We use a variety of methods to assess the quality of each device, intending to provide potential customers with the most detailed and accurate information possible.
First, we conduct performance tests on each air purifier using a laser particle meter. This allows us to measure the device's effectiveness in removing airborne particles, which is an essential aspect of its performance. We also conduct noise tests on each speed setting to ensure that the device operates quietly and won't disrupt your daily routines.
In addition to performance and noise tests, we also assess the energy consumption of each air purifier. This is an important factor to consider, as it can impact the device's overall efficiency and cost-effectiveness. We use a specialized meter to measure the device's power consumption and evaluate its eco-friendliness.
To get a more realistic picture of each air purifier's performance, we also conduct real-life tests under normal usage conditions. We use the device for an extended period, typically during allergy season or while cooking, to see how well it performs in real-world scenarios. This helps us evaluate the device's effectiveness in removing allergens, odors, and other airborne pollutants.
Finally, we have developed a unique smoke test that allows us to evaluate the air purifier's ability to clean the air quickly and effectively. This test gives us a clear picture of how fast the device can remove smoke and other airborne pollutants, which is essential for maintaining a healthy and safe indoor environment.
Our testing process is designed to provide potential customers with a comprehensive understanding of each air purifier's strengths and weaknesses. By considering multiple factors, including performance, noise, energy consumption, real-life usage, and smoke testing, we can help you make an informed decision when choosing an air purifier for your home or office.
What to Look for in an Air Purifier
When it comes to choosing the right air purifier, there are several key factors to consider to ensure you get the best device for your needs.
Filtration Technology
The first and most important thing to look out for is the filtration technology used by the device. True HEPA filters are the most efficient and effective, able to remove 99.97% of airborne particles that are 0.3 microns or larger. However, there are also other filter types available, such as HEPA-type and similar filters, which are less efficient than true HEPA filters. It's essential to distinguish between these different types of filters when making your decision.
CADR (Clean Air Delivery Rate)
In addition to filtration technology, room coverage is also a crucial factor to consider. Make sure to choose an air purifier that is designed for a room of your size, as the device's performance may be impacted if it's not suitable for the space. Check the Clean Air Delivery Rate (CADR) to determine how quickly the air purifier can clean the air in the room. A higher CADR means the device can clean the air faster.
Smart Feature
Other features to consider include smart apps, air quality sensors, auto modes, and more. While these features don't directly impact the filtration quality, they can still affect the device's efficiency and performance. For example, a smart air purifier can be set up to automatically adjust its settings based on the air quality in the room, ensuring that the air is always clean and healthy to breathe.
Final Thought
Our list of the best air purifiers we've had the opportunity to test so far aims to provide a comprehensive guide for individuals looking to improve the air quality in their homes or offices. By comparing the capacity, volume, energy consumption, and reliability of various air purifiers, we hope to help you make an informed decision and find the best air purifier for your specific needs. Whether you're looking for a device that can handle large spaces or one that operates quietly, our top picks - the Coway AP-1512HH, Levoit Core 300, and Winix 5500-2 - offer a range of features and benefits that make them excellent choices. Remember, the best air purifier for you will depend on your unique circumstances, so be sure to consider your needs and preferences carefully. With the right air purifier, you can breathe easily and enjoy the benefits of clean, healthy air.
FAQs
What features should I look for?
When selecting an air purifier, there are several important features to consider. One of the top things to look for is a true HEPA filter rated to capture at least 99.97% of fine particles. An activated carbon filter that removes gases and odors is also beneficial. Make sure to evaluate the CADR or clean air delivery rate, as it indicates how fast the unit can clean the air. Sensors that detect pollution levels and adjust speeds automatically are useful too. Pre-filters that trap larger particles extending the lifespan of main filters are a nice plus. Opt for a model with timer functions and connectivity for convenience.
What size purifier do I need?
The appropriate size air purifier depends on the room. For spaces up to 150 square feet, a purifier with a CADR between 110-149 is suitable. Rooms measuring 150-300 square feet do well with a CADR rating of 250-400. If cleaning a large open concept area over 300 square feet, you'll want one with a higher CADR of over 400-500 for best effectiveness. Be sure to consider clearances around the unit too.
What brands are best?
Top-rated brands like Blueair, Molekule, Coway, Honeywell, and IQAir consistently perform well in side-by-side lab tests and user reviews. Independent analyses show they remove particles efficiently. Dysons and others offer premium features and styles as well. Choosing from a trusted brand provides quality and peace of mind.
How often do filters need changing?
True HEPA filters maintain performance for around 6-12 months with typical use before replacing. Activated carbon filters need swapping every 3-6 months. Washing any pre-filters monthly keeps them working properly. Regular maintenance like this keeps the air purifier running optimally.
