"For anyone who uses a portable air purifier correctly, a portable air purifier has the potential to improve indoor air quality. The longer the air purifier runs, the more air it filters." Tim Carroll, Environmental Protection Agency

An important feature to pay attention to when buying an air purifier for allergies is the High Efficiency Particulate Absorption (HEPA) filter, which uses very thin glass fiber threads to capture the very small particles in the air and trap pollutants. According to a report by the Environmental Protection Agency, this type of filter "in theory can remove at least 99.97% of dust, pollen, mold, bacteria, and 0.3 micron particles in the air." Speaking of choosing the perfect air purifier, Environmental Protection Agency representative Tim Carroll told Live Science: 

"Selecting the right air purifier will depend on the type of pollutants the user is targeting. Generally speaking, to filter particles, please choose a clean air delivery rate (CADR) portable air purifier that is large enough to accommodate the type of pollutant you will use. The size of the room or area."

Levoit 400S is our first choice of air purifier to prevent allergens in the home, and this is for good reason. 

Levoit 400S received an impressive 5 stars (out of 5 stars) on Amazon. Critics commented on its ability to purify the smell and dust in the air. The stylish appearance of the Levoit 400S has also received positive reviews, but some people think it is a bit bulky.

Not only did it perform well in all our tests, but it was also an affordable option, which meant that those with limited budgets did not have to sacrifice their air quality. Equipped with a HEPA H13 filter, this air purifier has passed our tests under various conditions and absorbed 99.9% of particles smaller than 0.3 microns at a specific time. 

Levoit 400S is not only a powerful air purifier, but also points for its stylish design, smooth edges and easy-to-operate handle. Thanks to the intuitive controls, the setup of this device is very simple, and the app connected to the purifier provides a lot of information, allowing you to count the history and current air quality in your home.

If you suffer from allergies and need a unit to cover a larger room in your home, then Blue Pure 211+ is your ideal choice. 

Blue Pure 211+ received 4.8 out of five stars on Home Depot. Those who left a positive review were impressed by the capabilities and stylish design of this air purifier. Some unimpressed users commented on the cost of replacing the filter.

Although it is a larger and heavier model, the result is that it can cover rooms up to 600 feet, which is impressive. However, this increase in coverage does not mean that running Blue Pure 211+ will go bankrupt. On the contrary, this air purifier is also very economical to operate, and there are a variety of colors to choose from, making it easier for you to pretend to be at home.

The performance of Blue Pure 211+ in our series of tests proved that it ranks among the best in its class of air purifiers; it can absorb particles in a variety of conditions in the most effective way we have seen. If you are a smart home enthusiast, the lack of functionality of Blue Pure 211+ may be a little lacking for you, but for simple and straightforward operation, this device should be very suitable.

Like any Dyson product, Dyson Purifier Cool has a stylish and well-designed design. 

Dyson Purifier Cool has an average score of 4.2 out of five stars in Home Depot. The unmoved reviewer cited sensor baseline readings and noise issues during use. On the other hand, positive reviews praise the purifier's ability to improve the symptoms of allergy sufferers and remove unpleasant odors. Of course, customers also particularly like the integration with smart devices, automatic settings, and the cutting-edge design of the purifier.

The device will definitely not disappoint in these aspects, and it also has practical advantages and can double as a cooling fan. In addition to its aesthetics, this purifier also performed exceptionally well in our test program. Our test concluded that when used at the highest setting for at least 30 minutes, it usually captures more than 95% of the monitored particles.

When assisting in cleaning allergens in the air, Dyson Purifier Cool is designed to remove tiny particles smaller than 2.5 microns, including smoke, bacteria and allergens-shown as PM 2.5. If you want your home to relieve allergy symptoms-especially during the pollen season-then another ingenious trick of Dyson Purifier Cool is that you can set the machine to start working remotely, all of which can be done through the machine's app. Although this air purifier may not be in everyone's price range, it has a lot to deliver, and the eye-catching design makes the deal even sweeter.

If you are struggling with allergies and are looking for an unremarkable air purifier to add to your home, then the Rabbit AirMinus A2 Spa-780a is designed for stylish and stylish homes. 

According to reviews collected on the Rabbit Air website, the Rabbit AirMinus A2 Spa-780a has an average score of 4.7 (out of five stars). Some unmoved reviewers complained that the setup was cumbersome, but many positive reviews praised the air purifier's ability to clean air in a large area.

This device can be wall-mounted or used as a portable purifier, and it is impressive in many ways. Its standard coverage area is 700 square feet, which is very suitable for larger spaces, and CADR can capture pollen, dust and smoke in a designated space of this size. When buying an air purifier for allergies, it is important to pay attention to the stable clean air delivery rate (CADR), and this air purifier claims to have a high delivery rate for all these allergens.

There are many practical features to consider when choosing an air purifier for your home. This Rabbit Air AirMinus A2 Spa-780a uses ultra-quiet design, which is definitely the primary consideration for light sleepers. The design of this air purifier means that you may not even notice its presence, but you will definitely feel its benefits in terms of air quality.

Coway AirMega 250 has become a popular air purifier because of its high-end design, and claims that it can filter 99.99% of the fine particles in the air. 

Among 92 reviews collected on Amazon, the Rabbit AirMinus A2 Spa-780a has an average score of 4.7 (out of 5 stars). Fans of this air purifier are impressed by the quiet operation of this air purifier, but others are a little confused about the setup process of this model.

It has a three-stage filtration system, which is ideal for allergy sufferers, and provides you with useful instructions on when to replace the filter and the easy-to-clean filter itself. Its performance is also very comprehensive, covering up to 930 square feet, which is one of the most impressive coverage we have seen. 

Although expensive, the Coway AirMega 250 does not have the smart features you might expect. Although it is not possible to control this device from a mobile phone, there are still some smart features, including an automatic mode that can change the mode and fan speed according to room conditions. This is an excellent choice for power and coverage, and has a completely stylish design.

Among the 34,876 reviews collected on Amazon, the Bacteria Guard AC4825E scored an average of 4.7 points (out of five stars). Many users say that this smaller air purifier is very suitable for daily use and helps relieve allergy symptoms. Other commenters who were not impressed stated that they felt they needed a more sophisticated filtering system.

The device is equipped with a HEPA filter and a charcoal filter to filter out odors, which can make your living space better. It is also super silent, which means it can run in the background without alerting you. 

As you would expect from a smaller unit, this air purifier does not cover as extensively as the bulky model. It is suitable for a single room, not a vast space, and is only 22 inches high, which means it will not cause much damage to the decoration of your room. There are also some other convenient features, including an indicator light to indicate the filter replacement time and three speeds including an ultra-quiet sleep mode, so that you can keep the machine running until late at night.

Once you get an air purifier for allergies, you must carefully maintain your equipment to produce the best results when alleviating these annoying symptoms. When cleaning, especially if you suffer from severe allergies, be sure to wear a mask and gloves to protect yourself and follow the manufacturer’s recommendations to avoid damaging your equipment. 

When disassembling, replacing or cleaning the filter in the air purifier, please handle it carefully to avoid moving the fine filter. Certain types of HEPA filters are washable, but be sure to check your personal equipment before taking action. Remember to also pay attention to the appearance of your device. Wipe clean and keep the entire air purifier clean.
