In terms of performance, the Levoit 200S is efficient, clearing out particulates quickly. It significantly outpaced competitors like the Dyson Purifier Cool Gen 1 in air purification speed. However, this model is on the pricier side and weighs 13 pounds, making it a bit cumbersome. Additionally, replacing the filter can be a bit of a hassle.
Overall, the Levoit Vital 200S-P Air Purifier offers a balance of smart features and strong performance, making it a top choice for those seeking a reliable air purifier.
In terms of sound levels, the “night mode” option on the Blue Pure 311i Max is the quietest setting available. This air purifier features an integrated RealTrack auto sensor that adjusts fan speed based on air quality. The unit also includes touch-sensitive buttons on top and can be controlled remotely via an app (available on Android and iOS) which notifies you when it’s time to clean or replace filters.

However, it may be considered expensive and its tall design could be a drawback for some users.
Moving on to the review of the Winix 5500-2 Air Purifier, this model is one of the tallest and heaviest units tested, standing at nearly 24 inches and weighing 17.5 pounds. Designed for small-to-medium rooms up to 360 square feet, it features a True HEPA filter, carbon pellet prefilter, and “PlasmaWave” filter technology that effectively cleans 99.97% of airborne pollutants as small as 0.3 microns. The integrated sensors monitor air quality and adjust fan speed automatically in Auto mode. Additionally, it offers a quieter Slee mode, a timer function, and an LED light that changes color based on air quality levels. While the Winix 5500-2 is a decent air purifier with real-time air quality monitoring and a washable prefilter, its tall stature, heavyweight, and limited effectiveness compared to the WINIX 5510 model may not suit everyone’s needs.
Lastly, the Coway Airmega 200M is recommended for larger spaces, covering up to 1,748 square feet in an hour or 874 square feet in just 30 minutes. Although it is ideal for small-to-medium rooms like bedrooms or home offices, this model excels in larger areas. The setup involves removing the faceplate to access three filters: a thin prefilter, secondary carbon filter for deodorizing, and the primary HEPA filter. While the process is manageable, it may pose a challenge for those with limited dexterity due to the intricacies of filter insertion. The mesh prefilter is washable for easy maintenance. Operating slightly noisier than other models on higher speeds, the Airmega 200M effectively reduces pollutants, odors, and volatile compounds, making it suitable for various environments.
The air purifier features a three-part filter system that effectively cleans the air, leaving very little odor behind within minutes. In Auto mode, the fan adjusts in real-time based on air quality, while Eco mode conserves energy by turning off the fan after 30 minutes of purified air (restarting if pollution is detected). An LED indicator shows air quality: blue for good, purple for moderate, and red for unhealthy, with an option to turn it off for use in bedrooms. Despite the lack of smart features, the purifier includes a filter replacement alert, timer function, and is available in white or black. Although it is a bit pricey and can be loud, the Airmega 200M is suitable for medium to large rooms. Other tested air purifiers include the Dyson Purifier Cool Gen1, known for its stylish design and quiet operation, and the Levoit Core 300-P, a budget-friendly option with efficient air purification.
Looking for an efficient air purifier that can handle clean air effectively? The Levoit Core 300 proves its worth by swiftly reducing PM2.5 levels in a small room, from 253 micrograms per cubic meter to four in just 15 minutes on its max setting. While it lacks an Auto setting or air quality sensor, this compact unit gets the job done when placed on high. The touch panel on the top, featuring large symbols for easy control, allows for quick adjustments. One downside is that it can get dirty quickly when used in the kitchen, but the filter is easily replaceable with a simple twist of the bottom panel. If you’re seeking a small yet powerful air purifier that requires occasional attention, the Core 300 is a solid choice. On the other hand, the Coway Airmega AP-1512HH offers a funkier design compared to its predecessor, the Airmega 200M, at a more affordable price. Equipped with multiple filters and an ionizer, this purifier effectively cleans air in rooms up to 361 square feet. It features a real-time sensor for monitoring indoor air quality and offers both Auto and Eco modes for energy efficiency. While slightly less powerful than the Airmega 200M, the AP-1512HH is still a reliable option for medium-sized rooms. Just keep in mind that replacing the filters may require some effort. For those in need of an air purifier for small to medium-sized rooms, the sleek Coway Airmega 100 presents a quiet and stylish solution. With the ability to purify up to 810 square feet, this cylindrical purifier combines performance with aesthetics.
The compact Airmega 100 air purifier proved to be efficient and effective in purifying the air in a closed room, achieving an impressive air quality improvement of 97% with a reading of 1.0 μg/m3 after just 30 minutes of operation. Its replaceable HEPA filter, featuring an integrated prefilter, only needs to be changed annually, although this frequency may vary based on air quality conditions. While it excelled in most aspects, it lacked the ability to remove airborne gases and odors due to the absence of carbon pellets. The cylindrical design with 360-degree air intake was both space-saving and efficient. An innovative feature of the Airmega 100 is its color-coded top, which changes based on the real-time Air Quality Indicator (AQI) readings, signaling good quality with blue, moderate with green, bad with orange, and very bad with purple. Despite lacking app support and a remote control, the Airmega 100 offers multiple speeds, a sleep mode, and a filter alert system for easy maintenance. Priced affordably at $83 on Amazon, this air purifier is a solid choice for its value, offering compactness, ease of use, and quiet operation.
The HPA090 air purifier is equipped with a True HEPA filter and carbon prefilter that can capture particles as small as 0.3 microns, effectively eliminating pollutants and odors. Despite its plasticky appearance, the device operates efficiently with four cleaning levels and an adjustable auto shutoff feature. While it lacks automatic air quality assessment, it offers a simple “set it and forget it” option. Additional features include a filter replacement reminder, dimmer option, and CADR Ratings of 100 for smoke, 106 for dust, and 100 for pollen. However, during testing, it did not perform as well as other units in removing smoke or cooking smells, indicating that there are better and more affordable options available.
Pros:
– Includes remote control
– Real-time air quality monitoring with light indicators
– Washable prefilter
Cons:
– Tall and heavy design
– Did not perform as well as other units tested

The odors originated from routine activities such as cooking and smoking cigars. Like the particulate test, we operated the air purifiers for a minimum of 30 minutes and then conducted a literal smell assessment.
Importance of Value:
Performance and user experience are crucial factors, but we believe they should not compromise the value. Our evaluation included overall pricing, filter replacement costs, and the clean air delivery rate, an industry benchmark representing the volume of clean air produced by a purifier in a minute.
Types of Air Purifiers:
HEPA Filters: HEPA filters are highly efficient in removing particulates, certified to eliminate at least 99.97% of particles that are 0.3 microns in diameter. They are made of tightly woven fibrous material like plastic or fiberglass and are effective against pollen, dust, and large bacteria but not viruses.
HEPA-like Filters: These filters have a similar structure to HEPA filters but do not meet the same standards. They mimic the filtration levels of lower-end HEPA filters.
Activated Carbon Filters: Activated carbon filters, created by introducing hot gas or acid to charcoal, are effective in reducing odors by trapping odor-causing chemicals. They are best paired with another filter type for particulate removal.
Electrostatic Filters: These filters charge particulate matter as it passes through, causing dust and pollen to adhere to the filter. They require regular cleaning and are suitable for particulates but not effective in removing odors. They can produce ozone, potentially irritating individuals with respiratory conditions.
Shopping Considerations:
Filter Types: Different filters target different pollutants. Pre-filters are ideal for pet hair, carbon filters for odors, and HEPA filters for fine particulates.
Size: Consider the square footage the purifier can cover, where it will be placed, and whether you need portability.
Features: Choose purifiers with features that suit your preferences. Some models offer essential oil diffusers or air quality updates to your phone.
Air purifiers are an important investment to ensure you are getting the most out of what you pay for. In addition to the initial cost of the unit, you must factor in the expense of replacing filters, which can vary from affordable to costly, especially for units with multiple types of filters. Consider the size of the air purifier when shopping, as they come in compact or large sizes depending on where you plan to place it in your home.
FAQs
Why should you get an air purifier?
An air purifier cleans the air you breathe by removing small particles, pollutants, and contaminants that can pose health risks. They are particularly beneficial for reducing allergens like pollen, pet dander, dust, and mold spores, as well as filtering out pollution, smoke, and chemical fumes. Air purifiers can also help with eliminating bad odors caused by cooking or pets, and may be effective against viruses and bacteria. Individuals with asthma, allergies, or respiratory sensitivities can greatly benefit from using an air purifier.
Do I need an air purifier with an app?
Having an air purifier that can be controlled via a remote or app on your smartphone or tablet offers convenience and allows for easy adjustment without touching the unit directly. Some models can send notifications about air quality levels or when it’s time to replace the filter. Certain WiFi-enabled air purifiers can even be controlled using smart speakers like Google Nest or Amazon Echo.
Do I need an ionizer with my air purifier?
The benefits of an air purifier with an ionizer are debatable. While an ionizer can help sanitize the air by producing ozone gas to combat harmful particles like bacteria and viruses, it may also irritate the respiratory system, especially for those with asthma. Compared to HEPA filters, ionizers are less effective at removing larger particles like dust and pollen.
What size/strength of air purifier do I need?
The size of the air purifier required depends on the dimensions of the room it will be placed in. Larger rooms with higher ceilings will need a more powerful purifier. Look for features like automatic air quality detection, easy filter replacement, app support, timer functions, and quiet modes when selecting an air purifier.
How much maintenance do air purifiers need? How often should filters be replaced/cleaned?
Air purifiers generally require minimal maintenance, primarily involving filter replacement and occasional cleaning. HEPA filters should be replaced regularly, and the frequency of cleaning or changing filters will depend on the specific model and usage.
Filters in air purifiers typically need to be replaced every 6 to 12 months, depending on various factors such as usage frequency, environmental conditions, and filter quality. The air purifier itself or a connected app will often notify you when it’s time to replace the filter. Additionally, carbon pre-filters should be replaced every 3 to 6 months, while mesh pre-filters can be cleaned approximately once a month. Some air purifiers come with permanent filters that require regular cleaning rather than replacement.
