Best Air Purifiers

Have you ever stopped and considered what kinds of particles and bacteria you are breathing in inside your own home? The thought can be quite horrific, to be very honest. As you clearly can’t see them as they are invisible to the naked eye, you may need to look into a remedy to not only live in a cleaner home but also potentially enhance your health. This so-called “remedy” is an air purifier.

But, what makes them so great? Speaking for the ten that made their way on this list, they have impeccable efficiency rates and nine times out of ten, a HEPA filter integrated. Most also are designed with a multiple step filtering processes to eliminate nearly 100 percent of all allergens and particles in the air. Simply put, they are worth the money.

Expand to see more
Efficiency
Both the charcoal filter and HEPA filter work together to remove common odors from smoking and cooking and 99.97 percent of dust and allergens, respectively. Plus, this unit is certified by Intertek.

Functionality
Designed into this unit is a UV-C control and this can destroy harmful micro-organisms floating around in the air. Additionally, there are three-speed controls and a filter-change indicator.

Size and Coverage
Unlike other air purifiers, this is actually a speed tower; thus, making it a highly compact and portable machine. It is best used for medium-sized rooms, though, as it is not efficient enough to handle larger scales.

Noise Factor
About the only time users seemed to even notice the noise outputted from this tower was on its highest setting. As the seller points out, though, during initial setup you may notice a mechanical noise but that should subside.

Maintenance
Overall, it is very simple to remove and replace the filters on this machine. According to the manufacturer, you can expect them to last anywhere from six to eight months (depending on usage).

Overall
If pure power and square-foot coverage are not your priorities and you would rather go with a compact and portable unit, this is ideal. It is still highly capable of a high performance; so, do not be confused about that.
Pros
  • Uses a three-step filtering process
  • Includes a filter change indicator
  • Has integrated UV-C light technology to kill various bacteria
Cons
  • In a dark room, the illuminating blue light is very distracting

Expand to see more
Efficiency
Utilizing a three-step cleaning process, Winix is able to achieve optimal results with their 5300-2 design. This is highlighted by the true HEPA filter.

Functionality
You can manually set the speed of this unit thanks to the four different settings. On top of this, the integrated Auto mode adjusts the fan speed accordingly and the smart sensor gauges the air quality.

Size and Coverage
This is rated to handle square footages of 360. While it may not be able to handle extremely large rooms, it should do quite well for medium-sized and slightly larger rooms.

Noise Factor
Another design mode integrated into this machine is a sleep mode. This enabled a small amount of noise for a suitable night-time environment.

Maintenance
On the control panel, an LED indicator light will be displayed when you need to change the filter/filters and will not disappear until you have done so. Typically, the HEPA filter will last a year and the carbon pre-filter six months.

Expand to see more
Efficiency
Much like the endless amount of elite air purifiers in the world, the Blueair Classic 205 sports a HEPA filter that promises to capture up to 99.97 percent of airborne particles in the air.

Functionality
Not only can this be operated via the Blueair Friend app, it is also compatible with Amazon Alexa for even further convenience. Past this, there are three different fan speeds.

Size and Coverage
As this is rated to handle areas up to 279 square feet, it is not the best option for larger rooms and should be demoted for only small and medium-sized rooms.

Noise Factor
The claim is that this unit is whisper quiet in operation as it requires less air pressure than other models. Yet, various feedback has contradicted this statement a bit as some feel it is too noisy.

Maintenance
Replacing the filter when it is necessary is about as easy as it gets with this machine. Simply remove the HEPA filter from inside and slide in a new one in its place.

Overall
Look, some people will not see the need for an air purifier with built-in Wi-Fi functionality. That is a fair assessment but truth be told, it is quite convenient to control this from an application or Alexa.
Pros
  • It is Wi-Fi enabled and the Blueair Friend app is free
  • Certified by the California Air Resources Board
  • Features a very simple setup process

Coway Mighty

Coway Mighty
This is another air purifier that has been raved by fans and users. Its extremely compact design is convenient for those looking for a portable purifier and its performance is solid enough to deliver clean air to your home.
Expand to see more
Efficiency
Despite the fact that Coway implemented a HEPA filter with a 99.97 efficiency rate and a four-step filtration process, some testers have claimed that the clean air performance of this purifier is merely average.

Functionality
The true sensation with this design lies within its particle sensing technology. Because of this, the unit detects the current air quality of the room and adjusts accordingly. In addition, when it detects clean air after 30 minutes it will shut off.

Size and Coverage
Even though this is one of the most compact units on the market, it still delivers an impressive amount of coverage. It will lose its effectiveness in larger spaces; but, it can handle up to 360 square feet.

Noise Factor
For the most part, it seems that the noise is not a concern for Coway’s air purifier no matter which speed level it is on.

Maintenance
What is nice about the ideology that went into this design process is the pre-filter is washable. As such, replacing the filters does not need to be done as frequently.

Overall
It is a little bittersweet that the performance of this air purifier does not stack up to the higher-end models as its combination of size and functionality is superb. Still, it has been well-received by the vast majority of consumers.
Pros
  • One of the smallest air purifiers on the market
  • The pre-filter is washable
  • Indicates the current air condition of the room it is in
Cons
  • The carbon filter does not remove strong odors quickly
  • Not the most impressive cleaning efficiency

Levoit LV-H132

One rather convenient feature is this is designed to be either operated horizontally or vertically, making it highly versatile. In terms of its coverage, it is rated for rooms up to 160 square feet.

Noise Factor
Both the fan and the motor are efficiently designed to operate at low frequencies.

Maintenance
Per the recommendations of Hamilton Beach, you should plan to vacuum the permanent filter once every three to six months. Once again, this is an easy process so do not get hung up on that.

Overall
All in all, this is a very versatile unit that can be easily traveled from room to room and stood in different orientations. Ultimately, however, it can’t ascend any higher because of its limited performance.

  • The overall cleaning performance has been questioned

 

The Main Points We Focused On

Overall Efficiency

Air purifiers are going to live and die by their performance for a majority of consumers. They are all designed, in some shape or form, to clean the air and provide a healthier environment. Yet, some do so more efficiently than others. For instance, some air purifiers will perform a multiple step filtration process. Say an air purifier had a carbon filter, HEPA filter and UV light. Firstly, the air would enter through the unit and activate the first filter. Then, once the first filter has done its job, the air would enter in the second filter and then the UV light.

Most of the time, the key to determining the performance of air purifiers is to assess the filters. Firstly, you always want to look for a HEPA filter as this is used to rid the air of all allergens and particles. Well, almost all of them. If it is a true HEPA filter, it will have a 99.97 percent efficiency while a HEPA-grade filter will only have a 99 percent efficiency. Additionally, look for other filters such as a carbon filter or charcoal filter. These can eliminate certain odors, VOCs and smoke.

Design Features and Overall Functionality

It is actually quite surprising how many features are included on a typical air purifier, to be very honest. At their core, they are a unit designed to purify the air but they are so much more than that. For instance, several of them implement smart technology to take some of the guesswork out of play. As an example, some air purifiers will integrate an air quality sensor that will display the current air quality of your room in real-time. On top of this, some will take it to the next level and adjust the fan speed accordingly.

Speaking of adjusting the fan, it is important to note that air purifiers will be designed with multiple speed settings and modes. Most will feature standard speed settings from low to high, but other models will have modes for turbo or “auto” additionally. Another feature that may interest you is if you can program it to run for a certain amount of time. Lest ye forget, also, a handful of air purifiers may also sport Wi-Fi technology. This can be convenient when you need to operate the air purifier from a different location.

How Much Area Is Covered

Before you even begin searching for an air purifier, there are two important questions you need to ask yourself. Firstly, how many rooms do you want to use an air purifier in? Secondly, how big are said rooms? Why are these questions so important to you? It is quite simple, actually. It boils down to the fact that air purifiers are rated to cover a certain amount of square footage. If you have wanted to use a purifier in your living room that is over 500 square feet, a model rated to handle 200 to 300 square feet is not going to cut it.

Overall, if you need to cover a large amount of space then your options are a bit more limited. Remember, large air purifiers will still work for smaller rooms but not the other way around. Be sure to know the square footage of your intended rooms before you begin. In terms of the size itself for air purifiers, this goes hand-in-hand with the square footage. Generally speaking, the more compact and portable models will not be ideal for larger rooms.

How Much Noise They Output

Believe it or not, this is actually quite a critical assessment point for you. That is if the noise is going to be an issue for you. If you honestly could care less how noisy or quiet your air purifier is, then you can leap beyond this section. For the majority of you, though, this is going to matter. Whether you prefer sleeping with no noise or simply do not want to hear the air purifier while it is running, you need to assess the noise level. Clearly, this is where the speed control comes into play as the higher performance modes will output more noise. But, if your house is loaded with allergens and pollutants, you may need to run it on the highest setting for optimal results. Ensuring it is tolerable is key.

Specific models will also be designed to detect dark environments and trigger the unit’s sleep mode which will reduce the overall noise from the machine.

Overall Maintenance

It would be nice if the base price was all you needed to worry about when buying an air purifier. However, because they all use filters you are eventually going to need to replace them. But, from one unit to the next the filters can last a variable amount of time. In fact, some units are designed with filters that can last a few years; while others will need to be replaced every three to six months. Overall, this timeframe is going to depend on how much you use the machine and how hard you work it. As such, when you need to change the filters can vary.

This makes it ideal when designers integrate an indicator light on their unit that alerts you when it is time to change the filter. This way, you know exactly when it is time.

 

FAQs

Q: How Does Poor Air Quality Happen in the First Place?

Poor air quality outdoors is quite obvious as pollutants and allergens are constantly floating around the world every second. However, you may be wondering why you need an air purifier because you may believe your home is free from these types of airborne particles. Well, you should think again about that. Ironically, one of the leading factors to indoor air pollutants is that homes are so expertly sealed that they are not allowed to let any air in or out. Put two and two together and you will realize that when these airborne particles enter your home, there is no place for them to escape.

It is nearly impossible to prevent airborne pollutants, such as smoke, dust, and pollen, from entering your home as they are everywhere and you can’t see most of them.

Q: What Are UV Lamps For?

UVC lamps have been alluded to a few times in this guide. Yet, it has not been discussed in-depth and you still may be scratching your head to what they are and do for air purifiers. What happens is these types of lamps emit a UV-C light and it will kill microbes that are in the air. In addition, they will also kill all sorts of bacteria and viruses. But, UV lamps are not all butterflies and rainbows that is for sure.

One of the biggest issues with them is they can emit ozone which is a big no-no for people. Several people are aware of this and they will go out of their way to ensure their air purifier does not integrate them. As long as the lamp is a UV-C type and certified by the California Air Resources Board, though, you should have little to worry about.

Q: What Happens if You Do Not Change the Filter/Filters?

As you know, it is critical to ensure you stay up to speed with the condition of the filters inside of your air purifier. They will work their tails off and will need to be cleaned frequently and changed regularly. But, what would happen if you forgot to change them or clean them, or simply blatantly ignored them? At this point, you are doing yourself a huge disservice as the performance and efficiency of the air purifier will be astronomically decreased with a dirty or old filter.

Not only this but you also increase your risk of respiratory illness the longer you go without changing or cleaning the filter. You are basically running the unit for no reason and are merely wasting energy. Note, it is not hard to clean or replace the filters so there is no reason why you should be avoiding it.

Q: Where Should Your Air Purifier Go?

Clearly, air purifiers are made for indoor use so let’s just get the obvious out of the way. That does beg the question that several consumers have and that is; what is the best location to place an air purifier? Should it be placed in your bedroom, the living room or even in the bathroom? You will see this question on a plethora of different media sources and websites and the answer will remain mostly the same. It is only natural for you to place the air purifier in the room that you are present in the most.

For most people, this will be their bedrooms as they sleep there. But, if you can no longer breathe in your living room thanks to your pets then that may be the ideal place for it. Only you can answer this question as it really is dependent on you.

Q: How Long Should an Air Purifier Be Run For?

Not most people are made of money and must be meticulous with their spending and energy-saving habits. This can lead to a potential roadblock for some people as to get the most out of an air purifier, it needs to be run continuously. As soon as you shut down the unit, the indoor air particles and pollution will re-surface and the nasty cycle will repeat itself. Air purifiers are not going to prevent new airborne particles from surfacing; so be aware of that.

But, won’t this rack up the energy bill? Generally speaking, an air purifier will consume around 30 to 250 watts per hour. Obviously, this range is dependent on the size and model of the air purifier. The bottom line, though, it is not going to be too immense to the point where you can’t afford your Consumers bill any longer.

Q: Can You Tell if an Air Purifier is Working?

So, a majority of the pollutants and particles floating in the air are going to be invisible to the naked eye. As such, it is not as if you can merely assess the performance of the unit by looking around. Thus, the question remains; how exactly can you tell it is working and functioning properly? Within a few days of running it continuously, you should be able to detect a noticeable difference in the air. It should feel less stuffy and heavier and you should be able to breathe easier.

Truth be told, if you have a clean filter and are not noticing much of a difference, your current room may just be very healthy. Again, this is where it is nice when there is a real-time smart-sensor on your unit that will inform you of the current air quality of your room (which is another easy way to tell if it is functioning admirably).

 

Final Thoughts

Even though you may believe your home is perfectly clean and you have no need for an air purifier, think again. Yes, they can be an expensive unit and this serves as a convenient excuse for people to avoid them. But, can you really put a price tag on your health?
