Which Air Purifier is the Best?

The best air purifiers are designed to eliminate irritants, dander and other pollutants from your home's air. Not only that, but they can also improve health by relieving allergies and asthma symptoms.

No matter your lifestyle, budget or space requirements, an air purifier will fit the bill. These devices should be energy efficient and offer various settings to regulate indoor air quality in your home.

1. Blueair Blue Pure 211+ Auto

The Blue Pure 211+ Auto is a powerful air purifier that will clean your air quickly and effectively. It can eliminate common allergens such as pet dander, mold, dust mites, smoke - making it perfect for large rooms like living rooms or family rooms. With its high CADR rating of 98%, this air cleaner can clean large areas quickly such as bedrooms or living rooms alike.

The 211+ is equipped with a 3-stage filtration system consisting of fabric pre-filter, particle filter and carbon filter. It boasts HEPASilent technology which makes it quieter than many other purifiers on the market.

It also features an LED display that indicates the air quality in a room. The cycle changes through three colors - blue for good, yellow for moderate, and red for bad - depending on air quality.

The Blue Pure 211+ stands out among air purifiers due to its fabric pre-filter that sits before the intake grille. This design makes cleaning and maintaining it a breeze, which helps ensure its long-lasting performance.

Our tests revealed that the 211+ efficiently removed airborne particles of size smaller than 0.3 microns and 2.5 microns within 30 minutes - significantly faster than either IQAir Healthpro Plus or Alen BreatheSmart 75i which both took 24 minutes.

The Blue Pure 211+ purifier gets the job done much faster than most of its rivals, which is an advantage. Furthermore, this model is highly efficient and requires little energy consumption to run.

It features an easy-to-use Auto mode with a particle sensor to automatically adjust fan speed according to your requirements. Plus, its 360-degree air intake makes it suitable for placement anywhere in the room.

The 211+ Auto's patented 3-stage filtration is capable of eliminating a wide range of airborne pollutants, including pet dander, pollen, mold spores and smoke. Plus its HEPASilent technology keeps it quiet on its lowest setting at 23 dB averaging noise levels.

The 211+ Auto is highly effective at eliminating gaseous pollutants like smoke and gas from the air, though it lacks a True HEPA filter. For some users this may be disappointing as Coway AirMega and Winix 5500-2 are both better options in this category.

2. Dyson Purifier Cool TP09

The Dyson Purifier Cool TP09 is an impressive all-in-one fan/heater/purifier that will look great in any room. It's quiet and efficient, plus it boasts some smart features like Bluetooth remote and continuous monitoring via the Dyson Link app.

The Cool TP09 is not the cheapest option and owners of the original Dyson Pure Hot+Cool may not think it's worth upgrading. But for anyone seeking a fan/heater that also acts as an air purifier, this model is one of the best all-in-one fan/heater/purifiers we've reviewed - definitely worth considering if you're in search of a new one!

One of its primary capabilities is its capacity to eliminate formaldehyde and other airborne toxins. This is made possible through a solid-state sensor that can detect molecules as small as 500 times smaller than 0.1 microns, giving rise to formaldehyde levels up to 500 times lower than previously recorded values.

That means it can eliminate mold, pollen, dust and even airborne viruses such as H1N1 influenza. Furthermore, its catalyst filter helps neutralize any pollutants left behind after it's taken away.

In addition, the TP07 features an auto mode that automatically adjusts settings and monitors air quality in the room. It also has a night mode which dims the screen and sets the machine to its quietest settings. Furthermore, an inbuilt sleep timer can be set to turn off the device at a specified time.

There's an adjustable oscillation angle from 45 degrees to 350 degrees and manual tilt that lets you raise the fan head. Its display can be dimmed for convenience, plus it's magnetic so it can be stored on top when not in use.

The Dyson Link app for Android and iOS lets users control their purifier, monitor air quality in their room and set up purifying schedules. It also displays air quality ratings from green to purple based on the density of microscopic particles and volatile organic compounds (VOCs) detected by the purifier's sensors in your home.

3. Coway Airmega 150

Coway air purifiers have long been a trusted brand in the industry, and this model lives up to that reputation. Equipped with automatic speed control and a sensor to monitor air quality in your room, this machine can clean up to 214 square feet of space at once.

This compact model is an ideal fit for dorm rooms and other small areas due to its narrow 13.3-inch width, 18-inch height, and 6.5-inch depth. With such a small profile, you'll have no trouble maneuvering it around your house with ease.

The Coway Airmega 150 is an ideal choice for those who want to keep their home's air clean without breaking the bank. Its three-stage filtration system uses a washable pre-filter, deodorizer and True HEPA filter - all at an affordable price point.

The Airmega 150 filters feature indicators atop them that alert you when it is time for replacement. Deodorizing and True HEPA filters should be replaced every six months, while the pre-filter needs cleaning or replacement as necessary.

Replacing filters in an AC unit is as easy as taking them out and placing them back where they belong. To do this, take off the front panel, pull off any plastic covering the filters, then reattach them in their intended positions.

Another appealing aspect of the Airmega 150 is its top button that permits you to adjust the speed of the air purifier. This is beneficial as different speeds affect how quickly air moves through its filter and is cleaned.

This can be especially helpful in an environment with a lot of smoke. The button can be held down for maximum cleaning power and then pulled down when not in use.

The Coway Airmega 150 air purifier can clean up to 214 square feet of space at once, making it a great option for mid-sized rooms or small apartments. It also has a sensor which alerts you when air quality is poor and LEDs that change colors based on how clean the air is.

4. Alen Air Purifier

If you're in search of an energy-saving and user-friendly air purifier, the Alen BreatheSmart FLEX is an ideal option. Its compact size and light weight make it portable so that it can be moved from room to room for efficient air purification in different spaces. Furthermore, its impressive Energy Star rating means running costs will remain low in the long run.

This Alen air purifier boasts an impressive filtration system and has been tested to remove up to 99.9% of harmful particles down to 0.3 microns in size, making it a great option for people suffering from asthma or allergies, since they can reduce exposure to allergens in the air and improve their overall wellbeing.

Additionally, it can help reduce odors from pets, cooking fumes and other indoor sources. Furthermore, it removes dust particles, pollen and pet dander from the air.

With this unit, you have the option to choose between 4 True HEPA air filter types to meet your air quality requirements. For instance, you can get either a Pure (allergies) or Silver (asthma) filter to improve indoor air quality in rooms where people with allergies or asthma symptoms reside.

Furthermore, this purifier comes with a lifetime warranty - providing peace of mind in case the unit does not perform as promised. This is an advantageous feature that offers assurance in case something goes awry with your purifier.

The Alen 75i is an advanced air purifier designed to remove up to 99.9% of harmful toxins from the air. It can be used for treating asthma and allergy symptoms as well as other respiratory problems like colds and flu, while also helping reduce pet odors and cooking fumes.

This unit is incredibly quiet, which makes it ideal for people with breathing problems or other sensitive to noise. With only 39dB on the first speed and up to 55dB on turbo mode, this model offers a noise level of only 39 dB. Furthermore, there's a timer that alerts you when filter changes should be done as well as a safety lock that prevents children from playing with the device.
