Use a dedicated air purifier to reduce the amount of pollutants, odors, mold, dust and pet dander circulating in the home.

Whether you suffer from seasonal allergies, need to remove smoke and peculiar smells from your home, or just want to make sure that you do not inhale unnecessary pollutants, an air purifier is a good investment. An effective air purifier can remove large amounts of these particulates from your home—some as high as 99.97%—and make you confident that the air you breathe is as close to pure as the air you might get. These machines come in a variety of sizes and usually have digital reading capabilities, so you can accurately monitor their operating efficiency.

To ensure that your purifier works as efficiently as possible, make sure it uses a reliable filtration system. Look for models equipped with HEP​​A (High Efficiency Particulate Air) filters. They are designed to allow air to pass through relatively easily, while high-density filter systems can capture pollutants and particles in the air, some as small as 0.3 microns.

It is worth noting that one of the models we included, Blueair Blue Pure 211, does not technically have a HEPA filter, but uses an electrostatic filtration system to remove particulate matter. Although it uses different filters, tests from Wirecutter and Consumer Reports show that its effectiveness is comparable to the HEPA model.

To ensure that you accurately understand the future cost of the air purifier, please note how often the filter needs to be replaced and the cost of these replacements. In the long run, some models with higher initial costs will actually end up being more affordable than cheaper models that require more frequent filter changes.

If you plan to fix the air purifier in your home, please pay close attention to its appearance and style. It may be worth spending a little extra for a unit that matches your home decor or a unit with multiple colors to choose from. In order to make your purifier disappear more in the background of your room, please look for a purifier with manual display shutdown function, which will temporarily disable any bright LED display.

This Coway purifier offers a black or white color scheme with a simple and modern design. It will be a good choice for those who want a device that can be integrated into the existing home decoration. 

Its four-stage filtration process can capture up to 99.97% of allergens and can even remove unpleasant odors in the surrounding air. It can also continuously monitor the air quality in your home and provide you with real-time updates through the top-mounted control panel and easy-to-read color coding system. 

Using its automatic mode, the machine will even automatically adjust its fans based on these updates.

If you are a tech-savvy homeowner and already own a smart device like Alexa, then this Winix purifier and its Wi-Fi connection may be a convenient choice. You can easily monitor air quality and control device settings and airflow using voice commands, and you can even order additional filters by connecting to the Winix Smart app and using Amazon Dash. 

Its HEPA filter can capture pollutants as small as 0.3 microns, and the device itself is powerful enough to cover 360 square feet of space. However, it is one of the larger models we have included, so if you don’t have enough space, you may want to consider a more compact option.

If you don't need a humidifier to cover a large area, this low-cost, compact option may be just what you need. Although it may lack the power of larger models, this Levoit purifier is equally effective, equipped with a pure HEPA filter, pet allergy filter, and operating noise level as low as 24 dB. 

Its cylindrical design and 360-degree air intake make it an efficient and efficient machine capable of purifying air five times per hour in a space of 219 square feet. Its low weight of 8.8 pounds also makes it easy to move from room to room.

If you want to use a purifier in a large room up to 540 square feet, this Blueair model and its 3-step filtration system may be the perfect choice. 

In addition to a washable fabric pre-filter that captures large particles before they enter the device, this option also uses an activated carbon filter to filter out smells from pets, cooking, and smoking. The operation is also very simple, just a button can be turned on, and switch between different fan modes. 

Although this model is louder than most models, its wide coverage and powerful fan can make it worth a little extra noise. 

The compact size and detachable handle of this model make it ideal for looking for a portable purifier. Whether you plan to move it from one room to another, or take it with you on vacation, its 0.6-pound weight and 2.7-inch footprint allow you to move it almost effortlessly. 

The rechargeable battery makes it more portable, and the USB-C port provides considerable flexibility when charging is required. A single charge can last up to 2.5 hours in high places, but the small size is only suitable for a maximum space of 54 square feet.

This Shark model uses six micro fans to process the air passing through its filter, allowing it to capture 99.98% of dust, allergens and particles in an area of ​​up to 1,200 square feet. 

Although this model is larger than most of the options on our list, it is still relatively narrow at only 8.9 inches, so if it is placed near a wall or furniture, it will be less intrusive. However, if you have small children or noisy pets, this slim footprint combined with its 32-inch height may pose a tipping hazard, so keep this in mind. 

If you need to deal with a large space with serious purification needs, this Medify machine may be your choice. It is designed with maximum productivity in mind. It can clean a 3,700 square foot room in 1 hour, or a 2,500 square foot space in just 30 minutes.
