Our Top Picks

TOP Choice #1 Germ Guardian Air Purifier
Our Score:

This air purifier is in the shape of a tower, and it will ensure that the surrounding air is clean and healthy. Your comfort level at home can be adjusted to reflect your preferences thanks to a top panel that features three distinct speed settings, an ultra-quiet mode that activates when the fan is set to its slowest speed setting, and an optional UV-C light. This air purifier is ideal for use in rooms that range in size from medium to large, such as dormitory rooms, bedrooms, and other living areas. Because it can recirculate the air in a room at a rate of 4.8 times per hour, it is ideally suited for use in medium to large spaces. 

The level of power and efficiency that your cleaner possesses will be directly proportional to the filter that you choose to install in it. To keep the product's functionality at the highest level that is at possible, you must use the original GermGuardian replacement components. However, it isn't included in this purchase, so you need to buy it separately. In general, it is the best option for supplying clean air and getting rid of viruses

TOP Choice #2 LEVOIT Air Purifiers for Home
Our Score:

This air purifier has three different speed settings—low, medium, and high—to accommodate varying air quality levels and individual requirements. It cleans the air at a low level while producing only 25 decibels of noise, making it appropriate for a relaxing setting and the hours spent sleeping. The air in the room is circulated more than four times an hour to achieve quick purification. However, it would be best if you closed the windows so that the purifier can more effectively remove the dust from the air.

The Levoit air purifier has a contemporary design and a size that makes it ideal for use in medium or smaller rooms, such as offices and dormitories. Thanks to the included Built-in Replacement Indicator; you will not forget to replace your filter. It is recommended that you return your filter every six to eight months, depending on how often it is used and the air quality. In the evening, you can turn the light off entirely, switching between two different brightness settings that will assist you in seeing in the dark or choosing one of the brightness settings to help you see in the evening.

TOP Choice #3 Coway Airmega AP-1512HH True HEPA Air Purifier
Our Score:

Using a pre-filter, a deodorization filter, and a True HEPA Filter together can reduce the number of particles with a size of 0.01 micron by 99.999%, including pollen and other allergens. It can also reduce odor and volatile organic compounds by 99%. The fan automatically adjusts to purify your space most effectively as required, providing a new level of cleanliness in real time as it continually monitors the air quality to determine what is needed. In Eco Mode, the fan will turn off to save energy after the air quality in the room has remained clean for at least 30 minutes while the mode is active. The fan will turn back on when it detects pollution in the air.

A vividly colored LED displays an instantaneous reading of the cleanliness or filthiness of the air in your home at any given moment during the day. To facilitate sleeping, the light can be turned off. The air filter indicator will tell you when the filters need to be replaced and the pre-filter needs to be cleaned to function at their highest efficiency level. The only thing that may be improved is the positioning of the light; since it is on top, sleeping in it could be a little uncomfortable.

4 OION Technologies B-1000  Air Purifier
Our Score:
OION Technologies

The 3-in-1 filtration system captures up to 99.97% of particles in the air for a clean and fresh environment in any room. Germs, mold, and mildew can all be eradicated with the help of internal UV light. Smoke and pet odors are reduced thanks to an internal carbon filter's ability to absorb them. The cost of replacement carbon filters is reasonable, and their lifespans, which vary depending on how often they are used, average between 6 and 12 months.

The purifier is economical for you and the environment due to its low energy consumption (just 7.5W) and the absence of large filters that need to be replaced. It sanitizes without causing any disturbance to either you or the people around you. The electrostatically charged metal filter does not become clogged and can be easily cleaned with a wipe to restore its previous efficiency level. The only drawback is that it cannot be cleaned with water, and the filter needs to be replaced regularly to keep being used.

5 LEVOIT Air Purifiers
Our Score:

The sleep mode maintains the operation of the Core 400S throughout the night and will use the lowest fan speed possible (24 dB) to create an environment that is conducive to restful sleep and is as quiet as falling leaves. You will be able to monitor the progress of your home's air quality by consulting the graphs generated by the VeSync app as a result of the laser dust sensor's examination of the surrounding air for traces of airborne particles.

Handless control with Amazon Alexa and Google Assistant enables you to adjust the settings when your hands are full with other tasks, such as preparing food, caring for infants and children, or interacting with pets. You can plan your week by programming the air purifier to switch between different operating modes and fan speeds at specific times of the day. With the help of scheduling, you won't ever have to stress about forgetting to adjust your preferences. The downside is that if you put it into a timed outlet to turn it off automatically at night, switching the power back on does not restore to the settings you chose.

6 MSA3 Air Purifier
Our Score:
Membrane Solutions

With this product, rooms of up to 840 square feet can be cleaned in as little as one hour, and spaces of up to 500 square feet can be cleaned in just 36 minutes.

On the other hand, the volume is relatively high when it's turned up to the "turbo" setting. Despite this, it is an excellent product to use in every way.

7 AZEUS True HEPA Air Purifier
Our Score:

The design of the centrifugal wheel generates a more powerful airflow, which can clean an area of up to 1080 square feet in just forty-five minutes. When combined with ultraviolet light and an ionic generator, you will experience fresh air in minutes.

Tips and strategies for selecting the best air filter on the market

People are always attempting to make the best decisions for themselves and their families. Whether they're shopping for new shoes or a new automobile, knowing which best air filter to buy on the market might be difficult. Fortunately, this article gives some amazing keyword selection tips and tactics, so you don't have to worry about making a bad option!


An air purifier can be quite heavy - it can weigh up to 10 kg. Before you move the device between rooms, ensure that its weight is within your ability. You can move the unit more easily with wheels or carrying handles.

Sensors And Timers

Many air purifiers include sensors which can measure the amount of pollutants in the air and other parameters such as temperature and humidity. These sensors will display information usually on the unit, and (for Wi-Fi models) in an accompanying app. This may include a complete particle count or simple indicators such as green for healthy air or red for highly polluted.
One can program the purifiers to turn on automatically when the pollution level reaches a set point. This can come in handy for those who want the purifiers to work continuously.
If there is no way to program the sensor to automatically turn on or off, you can use a timer function to tell the unit when to start.

Remote Control

The remote control makes it easy to use, although not all models come with them. You can also connect your air purifier to your WiFi network. Some models can also be controlled by a smartphone or tablet app. Dyson Pure Cool's Pure Hot + Cool model, but not the Pure Cool Me, allows for access to data from an air purifier that can be accessed from your smartphone. You will then have information about what type of pollutants were removed.


An air purifier should have a range of speeds. When you have to quickly clean an area's air, you want to get powerful air flow. However, you can use a more gentle fan for nighttime cleaning in your bedroom. Oscillating is a good option to cover more room.
You can try using an ordinary fan, like a ceiling or pedestal fan. The purifier should have adequate air circulation. If it doesn't, then it could end up cleaning air all around the unit, which can leave pollutants behind.
You should be aware that your air purifier may become quite loud at its maximum settings.

Alternatives To Air Purifiers

You can also clean up your home without buying an air purifier by regularly wiping down your furniture and thoroughly vacuuming your floors. You can use HEPA filters on your vacuum to ensure you're not just blowing dust around the room. You can remove even more pollutants and dust by regularly mopping hard floors. Finally, make sure to air-condition the home when outside air is clean.

Room Size

The recommended room size for most air purifiers is usually listed on the product label. Consider buying an air purifier that can be used in larger rooms than your home. You might find that the purifier clears the room more rapidly on the fastest setting. However, it will still keep the room clean on the slowest and most comfortable speed. This is good for when you are sleeping.


Do Air Purifiers Remove Smells?

Air purifiers using activated carbon filter will eliminate volatile organic compound (VOCs) which can cause unpleasant smells. It could also be the particulates of scented candles or aerosols that cause a musty scent.

Do Air Purifiers Increase Or Decrease Oxygen In The Room?

They don't. The majority of air purifiers use fans to circulate the air through an interior filter chamber that captures any particles. This does not alter the original composition of the air. It can add or remove oxygen, or any other gases.

How Long Does It Take For An Air Purifier To Clean A Room?

This depends on how large the room is and not only the type of air purifier. Take measurements of your space to find a machine capable of cleaning the air in an area that is five times as large. It filters the entire room one time every twelve minutes. Although machines can purport to clean big spaces, they only have the ability to do so several times each hour.

Do Air Purifiers Work?

Yes. You should read the customer reviews to see which machines are more effective. They can remove dust and fine particles quietly and invisible from the air. If you don't live near a congested street, opening doors or windows to let in air can help improve the indoor air quality. An air purifier can be used in the colder months.

Where Is The Best Place To Put An Air Purifier?

An air purifier should be placed in an area that is equal or less than the CADR rating. A device that can effectively purify air in rooms less than 250 sq. feet should not be placed in the heart of large houses. You should ensure that the purifier isn't blocked from either its intake or output by placing it in a room with a large number of people. This means that the purifier should be out in open and in an area with consistent airflow.

Are Air Purifiers Effective?

Anyone can benefit from improving indoor air quality. If you had to choose between walking along a main street polluted or next to a park, the former would be your choice. Indoor air quality can be threatened by polluting substances, allergens and dust particles as well as candles, open fires, volatile organic compounds (VOCs), cleaning products and "off gassing." Here VOCs can be released for many years from plastics and paints. An air purifier can be described as "taking the green side" of the road. If someone in your family suffers from allergies or asthma, they can help.


Choosing the best air filter for your purposes might be a difficult challenge. It is critical to remember what you want to achieve with the purchase as well as any factors that may influence your selection. 
Whether it's as basic as reading reviews before purchasing or inspecting images of best air filter on the market from numerous perspectives. When you wish to locate another one, you may also look at the Alen FIT50 Air Purifier. Now, let’s pick one for you!
