Coway AP-1512HH White HEPA Air Purifier

The Coway AP air purifier generates sound levels ranging from 25 to 54 dB, thus ensuring sound sleep even at the highest settings. For the price you are paying, you get an amazing product with a true HEPA filter, impressive CADR, and Eco mode feature. The Eco mode feature of this Hepa purifier is one of the best features of this product. It consumes such low amounts of energy, that you can be certain it won’t create even a small dent in the monthly electricity bills. The air purification system of the Coway air purifier is also superb, it does the job perfectly and you can be certain that all the germs and pollutants will most certainly get eliminated. It has a 4-stage air purification system, it comes with 3 additional filters for any odor, pet dander, and gasses in the air. It also has an adjustable timer, with options of 1,4, or 8 hours setting. However, it does have a few negatives as well. It uses an ionizer, therefore it does generate a bit of ozone, however through consistent cleaning and maintenance, it won’t cause much of an issue. Also, the air purifier is small in size, thus if you have a large bedroom, then it won’t fit perfectly.


  • Excellent energy saver
  • Really quiet
  • Superb performance


  • Uses an ionizer, thus it does emit a small amount of ozone
  • The size is small, thus not perfect for large rooms

LEVOIT Air Purifier Vital 100

The Levoit Vital 100, is the perfect blend of power, noise level, and energy efficiency. It has a True HEPA filter, and by now you would be aware that the true HEPA filter is one of the best. It catches 99.97% of airborne particles, and it’s strong enough to purify 500 square feet. At night if you keep it on low, it will generate a maximum of 23dB, and if you place it across the room, you will barely hear it. Even though the energy consumption is not the best, it is not that bad, assuming you use it on a low or a medium, it won’t cause much damage to your pockets. The Levoit vital is also great for pet owners, it has a washable pre-filter that captures pet hair and lint. However, the negatives of this product are that it does not have that many features as some of the other products, the model does not have a pet-child lock feature which could be useful to many. Also, it can’t be controlled by a remote, you will have to go to the machine and press all the buttons, to activate its features.

Oransi mod Air Purifier

The Oransi MOD is one of the most powerful air purifiers you can find in the market today, the way it works is that it uses the filter to take in the dirt air, remove the particles, and shoot it back into the room using the fan. So while most of the smaller models don’t have the speed or size or power to keep up with all the air coming in from a large space, the Oransi has the capabilities to do so. The Oransi, even though sounds complicated is plain and very simple to use, it doesnt not have many complications to it. However, the downside to the Oransi is that, is does make much more noise than the other air purifiers on this list, which can be a negative to many, and also it is a bit expensive.


  • Touch Control panel
  • Large room coverage
  • Variable fan speed settings


  • Lacks n air quality sensor
  • Expensive

Blueair Blue Pure 411+ Air Purifier

The Blue Pure is one of the smallest and most compact air purifiers you can find in the market, and due to its small size, it’s also one of the quietest. It generates up to 17 dB at its lowest settings and 46 dB at its highest setting. It is definitely one of the quietest air purifiers you can find in the market, and also it has an Energy Star rating with a power consumption of only 1.5 Watts. The Blue Pure 411, uses a 3-stage filtration process, starting from the pre-filter for dust and pet air, particle filter for allergens, mold spores, smoke, and an activated carbon filter for volatile compounds. The Blue Pure 411, also has an ACH (Air Changes per Hour) rating of 5x, meaning you can expect your room to be purified every 12 minutes. The air purifier is very easy to operate, you can easily switch between three fan settings and turn the unit on/off with just one button. The disadvantage of this is that the light of the air purifier stays on all the time, and can be distracting for some. Also, as mentioned, the air purifier is small. Therefore if your room is large, it won’t be that effective.


  • Great ACH rating
  • Ultra-quiet with a 17 dB noise level in the lowest setting
  • Energy star rating
  • Cost-saver


  • The light stays on all the time
  • Is effective only if the room is small

Dyson Pure Cool Link Desk Air Purifier

The Dyson Pure Cool Air Purifier is one of the trendiest and coolest looking air purifiers you can find in the market and also, it is no ordinary air purifier since it also works as a fan with a 10 fan speed setting, how cool is that? The Dyson air purifier has a real-time air quality sensor, which allows you to track the number of indoor air pollutants, gasses, VOCs and even temperature and humidity in real life. Dyson has also added a reverse airflow feature to push air backward instead of in the front end and a night-time mode setting ideal for light sleepers. The last feature, which is one of the coles features, in my opinion, is that the air purifier can be voice-controlled. You can use your voice to control all the actions of the air purifier, except for changing the fan speed, oscillation, and airflow. The Dyson air purifier also has a 350- degrees oscillation and is easily adjustable to preferred area coverage. In terms of cons, as you can expect, for a product with this many features, the price tag is for sure going to be expensive, but if you look at all the cool and unique features it offers, the heavy price tag is justifiable.

  • Solid air purification
  • Dual functions, as an air purifier and as a regular fan

The Winix air purifier offers a 3-stage air purification system with its Plasma Wave Technology which is perfect for airborne bacteria and germs. The Winix air purifier also has a true HEPA filter and also has an activated carbon filter. The Winix air purifier works very similarly to an ionizer, but it does not release any ozone gasses, and also the ACH of the Winix air purifier is 4x, so it cleans your room every 15 minutes. The drawbacks of the Winix air purifier are that its filter replacement cost is high and also it has a high power consumption of 70 W. Some other cool features of this product are, it has smart sensors, and monitors air quality, and automatically adjusts fan speed settings.

Moreover, both the charcoal pre-filter and HEPA filters make the WP500 a highly efficient air purifier in trapping 99.99% of air particles although the filters are quite pricey. As mentioned, the Whirlpool air purifier does not have that many features, but it does come with a sleep mode function for the quietest operation with an 8-hour timer and also a child lock function.

  • All-in-one button control decreases usability rating

Okaysou Air Purifier

If you have a lot of pets, then the Okaysou is the perfect choice for you. The Okaysou zaps stubborn pet hair from the air with ease. Also, it only generates about 20-50 dB, which is really impressive. The dual pet hair filtration system catches hair, pollen, and dust that other models might miss.

Things to keep in mind


Choosing the right filtration technology is probably the most important part of buying an air purifier. Different types of filters can tackle different types of indoor air pollution. So make sure you purchase one that fits your specific needs.

The different types of filters are:

  • TRUE HEPA FILTERS: True HEPA Filters are rated to capture 99.97% of particles. They are the most efficient and tend to provide the best performance.
  • CARBON FILTERS: The Carbon Filters are perfect for capturing gaseous pollutants, such as VOC’S in the air through a process called adsorption. As these filters become more saturated, they become less effective. Activated carbon filters cannot remove particle pollution from the air.
  • PECO-FILTER: The patented Molekule technology destroys pollutants like VOCs at the molecular level.
  • IONIZERS: Ionizers work in a very interesting way, they release charged ions into the air. These ions then attach to airborne particles, giving them a charge that makes them either attach to surfaces in your home or fall to the ground. The technology used in some ionizers can create ozone as a byproduct, which may cause a long list of harmful health effects according to the California Air Resources Board (CARB).

As tech is improving day by day, more and more cool features are being added to the air purifiers. Depending on your needs and your room size, get an air purifier that is easy for you to use and also matches your decor.

Some questions to consider before making the big step are:

  • What are the dimensions of the air purifier?
  • What is the size of the room?
  • How complicated is the user interface?
  • How many settings options does the unit have?
  • Can the air purifier be controlled by a phone app or remote?
  • Will the air purifier notify you when it is time to replace the filters?

This has to be one of the most important factors to consider. We all would want a bit of silence, so having the constant whirring noise of the air purifier’s fans, will not provide us with that much-loved quietness. The quietest air purifiers in the market will have a dB rating of 20-40 at the lowest fan speed, while the loudest ones will be rated 50 to 70 dB and above.


You have to know how much energy your air purifier is consuming, otherwise at the end of the month, when you see your electricity bill, you may receive a mini shock. To keep energy costs low, try looking for units that use below 100 watts on their highest settings. The majority of modern air purifiers tend to use less energy, but even then it is best to confirm it before you purchase it.


Once you purchase an air purifier, you will most definitely need to replace the filters. Filter life can range from a few months to a year, depending on the pollutant levels in your home and the type of filtration technology in the unit. When considering the cost of an air purifier, make sure you add in the cost of replacing the filters. Also, remember this, some air purifiers have more than one filter to change. While these are the important factors or features that you should keep in your mind before purchasing an air purifier, there are some factors or features that you should avoid completely as well.

These factors/features include:

  • OZONE EMISSIONS AND IONIZING FUNCTIONS: Some air purifiers tend to emit ozone as a by-product of their operations, if that’s the case then, avoid it at all costs. Even a small child knows how harmful ozone is to the human body, therefore avoid such air purifiers at all cost. An easy way to check for this is to see whether the unit has been certified by the CARB.
  • PRIMARY UV-C LIGHT TECHNOLOGY: Like the ionizers, the air purifiers that primarily use ultraviolet UV-C light may also emit ozone. Again, to ensure that it doesnt, make sure it is certified by the CARB.
  • FANLESS AIR PURIFICATION: Fanless operation sounds like a good idea, as they would tend to make a lot less noise than a regular air purifier, but the issue without a fanless air purification is that it cannot get enough airflow to replace the air in the room, these types of air pollutants can only remove a small fraction of the pollutants removed by an air purifier with a fan.

We hope we were able to provide the best advice and guidance out there. Hope this article helps!
