Buyer’s Guide

When looking to purchase a smart air purifier, there are several important factors to consider to ensure you pick the right device for your needs. These factors include:

Room size and coverage area

It is important to choose a smart air purifier designed to handle the size of the room where it will be used. Some devices are designed for small rooms, while others can handle larger spaces. You can check the manufacturer’s recommendations for room size before making a purchase.

Filter type

Smart air purifiers use different types of filters to capture airborne particles. The most common filter options are HEPA filters, which are designed to capture particles as small as 0.3 microns, and activated carbon filters, which can neutralize odors and gaseous pollutants.

Some devices also use UV-C light to kill bacteria and viruses. Consider your specific air purification needs when choosing a filter type.

Noise level

Some models can be quite loud, which can be disruptive if you plan to set it up in your bedroom or home office. As such, you’ll want to look for a model with a low noise level or one that has a quiet mode for nighttime use.

Smart features

The term “smart air purifier” typically refers to devices that can be controlled and monitored using a smartphone app or voice commands.

When looking at the device’s specs, consider the specific smart features you want, such as integration with Amazon Alexa or Google Assistant, an automatic mode based on air quality readings, and filter replacement reminders.

Energy efficiency

Smart air purifiers can use a significant amount of energy, so it is important to choose a device that is energy-efficient. Look for a model with an Energy Star rating, which indicates that it meets strict energy efficiency guidelines.


Smart air purifiers can vary in price from around $50 to several hundred dollars. While you must consider your budget when choosing a model, you must also keep in mind that a more expensive air purifier may have more advanced features and better performance.

As much as possible, look for a device with a warranty that will protect you against defects or malfunctions. Be sure to read the warranty carefully to understand what is covered and for how long.

Brand reputation

Look for a brand with a strong reputation for producing high-quality air purifiers. To do this, you may want to check customer reviews and ratings to get an idea of how well the device performs in real-world use.

Operating costs

Remember to take into account the cost and frequency of filter replacements. Some models require filter replacements every few months, which can be expensive over time. You’ll also want to look for a device with a filter replacement indicator, which will alert you when it is time to replace the filter.


Smart air purifiers come in a variety of designs, from sleek and modern to more traditional. Look at the aesthetic of the device and imagine how it will fit into your home decor.

Smart Air Purifier FAQs

1. Are smart air purifiers a waste of money?

As a health coach, I would say that smart air purifiers are not a waste of money, especially if you are concerned about your indoor air quality. They can help reduce indoor air pollution and provide a healthy living environment for you and your family.

Ultimately, the decision to invest in a smart air purifier depends on your personal needs and budget. But in terms of health benefits, there’s no doubt that a good air purifier can be a valuable addition to your home.

2. Does every smart air purifier work with HomeKit?

HomeKit is a smart home platform developed by Apple, and not all manufacturers choose to integrate this technology into their devices. However, many models are compatible with other popular smart home platforms, such as Amazon Alexa or Google Home.

Check the manufacturer’s specifications before purchasing a smart air purifier to determine its compatibility with your preferred smart home platform.

It is also important to note that while compatibility with smart home platforms can provide added convenience, it is not essential for the basic function of the air purifier. Smart air purifiers can still operate effectively and provide cleaner air without integration with smart home platforms.

3. Where is the best place to put an air purifier?

I would recommend placing the air purifier in the room where you spend the most time. This is typically the bedroom or living room, which tends to have the most pollutants.

As mentioned, you must also consider the size of the room. Make sure the air purifier is powerful enough to handle the square footage of the room.

Placing the air purifier in a central location within the room can help ensure maximum coverage. Avoid placing it in a corner or against a wall, as this can restrict airflow and reduce its effectiveness.

Additionally, it’s best to avoid placing it near sources of pollution, such as near an open window or near a smoking area.

4. How do air purifiers and HEPA filters work?

Air purifiers and HEPA filters work by trapping and removing airborne particles from the air. These particles can include allergens, dust, smoke, and other pollutants that can negatively impact indoor air quality and overall health.

HEPA filters work by using a dense mat of fine fibers to trap and remove particles from the air. These filters can capture particles as small as 0.3 microns, including most airborne allergens and pollutants.

Basically, the device uses a fan to pull air through the HEPA filter, where the particles are trapped and removed from the air. Some models also use additional filters or technologies, such as activated carbon filters or UV-C lights, to remove even more pollutants.

As a health coach, I recommend using air purifiers and HEPA filters in conjunction with other healthy habits, such as proper ventilation and regular cleaning. This will ensure the best possible indoor air quality and promote overall health and wellness.

Which Is the Best Smart Air Purifier for You?

Investing in a smart air purifier can have a significant impact on your overall health. By choosing a purifier with advanced features, such as HEPA filters, air quality monitoring, and app connectivity, you can ensure that you are breathing clean, healthy air at all times.

Of the five smart air purifiers here, two stand out as the best options: the Govee Life H7123 and the LEVOIT Smart Core 300S.
