The best smart air purifiers of 2025

Why we like it: When testing this smart air purifier, I quickly noticed that just minutes after turning it on, I could feel the air becoming fresher and lighter. Aside from helping reduce my allergies, the Levoit Vital 200S is my go-to for whenever the air feels stuffy, or when we want to get rid of an odor, like after cooking a fragrant meal.

The Levoit Vital 200S is controlled by the VeSync app, which is intuitive and user-friendly, easy to navigate, and seamlessly compatible with Alexa and Google Home for voice control.

Review: Levoit Vital 200S

Who it's for: The Vital 200S is great for pet owners and allergy sufferers. Its front has a U-shaped inlet, which allows it to pull dust and particles as well as pet hair and dander more efficiently than other models. I keep it in my office, where I spend most of my time working alongside my dog. I appreciate how effective it is at getting rid of airborne particles and pet odors.

Who should look elsewhere: This air purifier, though smart, doesn't support Apple HomeKit. This means it's not a great choice for someone looking to integrate it with their Apple Home. It's also not made to be decorative or look like furniture, even if its functionality is quite solid. 

Levoit Vital 200S specs: Filtration: Three-stage filtration | Filter: H13 True HEPA filter | Connectivity: Wi-Fi | Noise: 24-54dB | Coverage: Large room; up to 1,900 square feet in about an hour | CADR: Not specified

• Easy to set up

Why we like it: While the Levoit Vital 200S is my go-to during the day, the Coway Airmega IconS is my favorite model for sleep. Aside from its sleek design, this smart air purifier is more successful at helping my allergies at night, even more so than the Levoit. 

I've taken medication daily for years due to dust and seasonal allergies, but I'm still congested and coughing during the night, no matter where I sleep. Being able to finally ditch my nasal spray and antihistamine has made my life easier. It's as simple as telling Alexa "good night" and knowing the Coway Airmega IconS will switch on to remove airborne particles. 

It also features a bonus wireless charger at the top, which I use to charge my iPhone and AirPods. Thus, it is a multipurpose device that can work in any room.

Review: Coway Airmega IconS

Who it's for: The Coway Airmega IconS has a fashionable design reminiscent of a modern piece of furniture. Its light, aspen-like color makes it blend in with any home decor, ditching the stoic and bulky design common with other air purifiers. It's perfect for those who value great air quality but don't want to sacrifice style.

Who should look elsewhere: Budget-conscious shoppers and people who don't care about what their air purifier looks like are probably better off with a simpler, more affordable air purifier.

Coway Airmega IconS specs: Filtration: Three-stage filtration | Filter: H13 True HEPA filter | Connectivity: Wi-Fi, Bluetooth | Noise: 21.7-49.3dB | Coverage: Large room; up to 649 square feet | CADR: 253

• Blends in with nearly all styles
• Bonus built-in Qi wireless charger
• Good for large areas

• Controls are not as intuitive as others
• Fabric cover can trap dust

Why we like it: This Morento air purifier has two high efficiency particulate air (HEPA) filters that quickly and thoroughly clean the air in a room. It's also one of the most affordable smart air purifiers available, selling for as little as $80. It has smart features to work with Amazon Alexa, Google Home, and the Havaworks app. It's also quiet, has a built-in display to show air quality, and is lightweight, at under eight pounds.

Review: Morento Air Purifier

Who it's for: The Morento air purifier is suitable for anyone dealing with allergies, pollen, or pets. It's easy to store and bring out during wildfire or allergy season because it's so light and compact. It also makes for a budget-friendly, quiet, smart air purifier for living areas and bedrooms. 

Who should look elsewhere: This is a pretty straightforward device, so it's not designed to blend into home decor and isn't multifunctional. Also, anyone looking for an air purifier to sit flush against the wall should look elsewhere, as this one has dual side-facing intakes, which means it sticks out awkwardly.

Morento specs: Filtration: Dual HEPA filters | Filter: HEPA filter | Connectivity: Wi-Fi, Bluetooth | Noise: 24dB | Coverage: Large areas; up to 1,076 square feet

• Great for large rooms and areas
• Inexpensive
• Affordable replacement filters

• Functional, but not stylish
• Can't be placed flush against wall

Why we like it: This compact Levoit Core 200S air purifier is perfect for small areas and lightweight enough to move from one room to another, weighing just over six pounds. Though small, it offers powerful filtration, cycling the air five times per hour in a 183-square-foot room at 360 degrees to tackle air pollution.

Just like the Vital 200S model, this Levoit smart air purifier can be controlled with the VeSync mobile app. The app allows you to set schedules and timers and connect to compatible voice assistants like Amazon Alexa.

Who it's for: This Core 200S air purifier is the perfect appliance for the nightstand in your bedroom or small living room. It helps you get rid of stale, stuffy air in favor of an odorless environment with improved air quality.

Who should look elsewhere: This air purifier is not for people who need filtration in larger rooms or spaces, offering only 183 square feet of coverage. If you're looking for an affordable smart air purifier for large spaces, this Morento model is perfect.

Why we like it: The multifunctional SwitchBot Air Purifier table is an air purifier, end table, nightlight, and wireless charger in a single device. As an air purifier, this one has my favorite feature: a washable pre-filter. You can wash off the mesh pre-filter every few weeks, which helps prolong the life of the HEPA filter, saving you money on replacements.

The Air Purifier Table also has a smart PM2.5 sensor to automatically adjust purification based on the room's air quality. 

Who it's for: The SwitchBot Air Purifier Table is perfect for people with limited space since it combines a table and an air purifier into one. It's also proven useful during my tests for pet owners who want to reduce dander and hair, as well as home cooks who want to combat lingering food odors.

Who should look elsewhere: The table surface is rather small, at 11.5 inches x 16.5 inches, so anyone who needs a larger surface area for their side table, as well as people who don't care for the extra features like the lights or wireless charging, should look elsewhere. A SwitchBot hub is required to connect the Air Purifier table to Wi-Fi.

SwitchBot Air Purifier Table specs: Filtration: Three-stage filtration | Filter:  Washable pre-filter, HEPA, and carbon filter | Connectivity: Wi-Fi, Bluetooth, Matter, Wi-Fi | Noise: 20dB | Coverage: Whole room; up to 3,620 square feet

What is the best air purifier?

The best smart air purifier is the Levoit Vital 200s since it combines all the best features for improved air quality at a great price. It features an H13 True HEPA filter as part of its three-stage filtration system. It can filter the air in a standard bedroom, up to 380 square feet, in only 12 minutes, and is quiet enough to stay on all night while you sleep. This smart air purifier is a breeze to set up, and the mobile app by VeSync is also quite easy to navigate. 

However, different preferences for price, coverage area, and noise level can affect which of the best air purifiers is ideal for your situation. Here's how the best air purifiers stack up:

Which is the right air purifier for you?

Choosing the right air purifier for you will depend on what your needs and priorities are, along with your budget. You may prefer a fashionable option or a quiet one, or you may not care what it looks like, just how well it does, or where you can install it. Either way, there's a choice out there for your needs.

In addition, sound can be an important factor. If you plan on running an air purifier in a bedroom, one with variable fan speeds and a low-decibel sleep mode can make it more convenient to operate at all hours.

How did we choose these air purifiers?

To choose the best air purifiers from the hundreds on the market, I looked at several important factors:

• Air change per hour (ACH): ACH determines how many times the air purifier can filter the air in a room in one hour.
• Power: I also considered how powerful the best air purifiers are, especially to determine what room size they're better suited for. Many air purifiers, like the Levoit models, can clean almost any room, and they'll just take longer to finish the work for larger rooms.
• HEPA filters: Besides size and ACH, the incorporation of HEPA filters was an important deciding factor. Short for high-efficiency particulate air, it's a pleated mechanical air filter that can remove airborne particles as small as 0.3 microns. This covers 99.97% of the particles found in the air, including pollen, mold, dust, and bacteria.
• Personal experience: As ZDNET's smart home expert, I tested and reviewed the top choices myself, as well as many others that didn't make the list. I gave our best choice overall, the Levoit Vital 200S, a 4- out of 5-star rating in my review.
• Customer reviews: For those I didn't have the opportunity to go hands-on with, I looked through a variety of customer reviews to get a well-rounded sense of real consumer experience.

FAQs on smart air purifiers

Do air purifiers help with dust?

While air purifiers cannot get rid of all the dust on the surfaces of your home, with frequent use, they can reduce the dust in the air, and you may notice dust less often. As a result, they can help prevent or reduce dust allergies.

In addition to air purifiers, using your vacuum cleaner at least once per week can help you remove dust from your home, especially if you have pets.

Can air purifiers prevent the spread of viruses?

The global pandemic we lived through just five years ago increased the demand for air purifiers. But do they actually work to stop the spread of viruses?

According to peer-reviewed medical studies, HEPA-filtered air cleaners can remove over 99.97% of airborne virus particles, especially when combined with other measures, even in school environments. 

Air purifiers alone aren't enough to stop the spread of illnesses like COVID-19, as they focus on removing potentially infectious aerosol particles from the air. Other measures, like masking and social distancing, must be followed in conjunction with air cleaners to make them effective at preventing the spread of illnesses.

Where to place an air purifier?

When shopping for an air purifier, remember where you'll be using it. There isn't a plug-in air purifier that can clean the air inside an entire household, unless it's a small living space. It's best to isolate areas, such as a bedroom, kitchen, or living room.

Once you know the size of the room you're working with, you can select an air purifier capable of efficiently circulating and cleaning the air in a room that size. A tabletop model is best for small spaces like a nursery or bathroom. A floor model can handle larger areas and may be portable enough to be moved from one room to another.

What is a HEPA filter?

A HEPA filter is short for high-efficiency particulate air filter. It's the finest type of filtration, able to capture particles as small as 0.3 microns. This includes bacteria, mold spores, pollen, dust, and nearly 99.97% of airborne particles.

HEPA filters are commonly used in the medical field due to their powerful filtration. Activated carbon filters are also common in air purifiers and are effective at removing odors from the air.

How often do I need to change the air purifier filter?

An important consideration for air purifiers is filter replacement. Some models require regular replacements of expensive filters, which could cost hundreds of dollars per year. 

Before you purchase a model, look into what type of replacement filters you'll need, how much they cost, and whether you can afford to replace them as required. Otherwise, choosing not to replace filters as recommended could reduce the air purifier's efficiency. After all, they capture and trap harmful particles, such as mold spores and bacteria. 

Some air purifiers feature washable filters, which make maintenance easier. However, the most effective air purifiers include HEPA filtration and carbon filters, which must be replaced. The manufacturer's requirements are in the manual.

Some modern purifiers have an indicator light that warns you when to replace the filters. As a rule of thumb, plan on replacing carbon air filters every three months and other filters every six months. 

What size air purifier do I need?

To determine the best air purifier based on the room size or area you're hoping to clean, look at a purifier's ACH rate and recommended room size. Most air purifiers will list the rate they circulate the entire volume of the room per hour by square footage.

And if you have an oddly shaped room, you might consider placing two smaller air purifiers to maximize air circulation.
