Best smart Air Purifier 2023: Let’s clear the air

According to the World Health Organisation, indoor air pollution was responsible for around 3.2 million deaths in 2020. Whilst the majority of these deaths were due to cooking on open fires or inefficient stoves, air pollution is a problem in all almost every household on the planet, with common househould items such as cleaning products or paint omitting volatile organic compounds (VOCs) that are harmful to health.


Thankfully, it’s possible to remove the vast majority of the pollutants in your home using an air purifier. These clever devices can suck in polluted air, trap the pollutants, and release clean air back into your home. Smart air purifiers take things a step further, allowing you to monitor your indoor air quality on your phone, even when you’re away from home, and ensure that the air in your home is always as clean as possible.

If you’re looking to improve the air quality in your own home, then here are some of the best smart air purifiers that you can get your hands on right now.

That means you control your SmartMi Air Purifier P1 with Siri on your iPhone, Apple Watch, or HomePod. Using the app, you can see the current air quality, pollen, and PM2.5 levels, and can set a schedule for when the device is active.

It’s intended for smaller rooms up to 320 square feet, but its smaller size means it won’t take up too much space, fitting easily on a side table. It’s also easy to move around, with a handle for easy relocation. The SmartMi P1 uses an H13 HEPA filter and can detect and filter PM2.5 and PM10 particles, but there’s no VOC monitoring.

The Dyson Pure Hot + Cool Air Purifier is compatible with Alexa, Google Assistant, and Siri, allowing you to control purification and cooling with your voice using your favourite voice assistant.

The Blueair Protect 7770i electrostatically charges particles as they enter the device, which ensures that even more of them are captured. It can even help to stop the spread of COVID-19.

7. Best smart air purifier for low noise

A wall-mountable smart air purifier that’s whisper quiet.

If you need a smart air purifier that won’t take up too much of your living space, then the wall-mountable Rabbit Air A3 could be a good option. It’s got a six-stage filtration system to capture everything from dust to VOCs, and is compatible with Alexa for voice control. It’s also incredibly quiet, especially on the lowest settings.

Pros

Even on its highest setting, it will only go as high as 51 dBA, so you’ll still be able to watch TV in the same room. It’s ideal for rooms up to 1,070 square feet, and uses a six-stage filtration system, including a BioGS HEPA filter and an activated carbon filter.

Using the app you can monitor the air quality, control the fan speed, or change the modes. You can even change the colours of the indicator light that provides quick visual feedback about the current air quality.

It’s a stylish design that can handle even larger rooms, and the triple filter is capable capturing even the smallest particles, including pollen, bacteria, viruses, odours, and VOCs.

How I chose the best smart air purifiers

When choosing air purifiers for this list, there were a number of considerations. First off, they all had to offer excellent air purification that would remove the vast majority of contaminants. They also had to have smart capabilities that were genuinely useful, such as voice control and the ability to remotely control your air purifier.

I also aimed to include options to cover a range of difference room sizes, from smaller rooms to much larger ones, as well as providing options that covered a wide range of budgets.

How to choose the best smart air purifier

When you’re looking for a smart air purifier, there are a number of important questions you should ask. The answers to these questions will help to inform your final decision.

Which smart home ecosystems are compatible with my smart air purifier?

If you’re looking for a smart air purifier, then you’ll want to be sure that it works with other smart home kit in your home. One of the most important factors is the smart home ecosystems that it supports. All the options on this list support Alexa, with most supporting Google Assistant too. However, Apple HomeKit support is less common. If you’re an Apple user, and you want to control your air purifier with Siri, then you’ll need to look for an option that’s HomeKit compatible.

Is the air purifier big enough for my room?

Another key factor in choosing an air purifier is the size of room that you intend to use it in. All air purifiers will give information about the area, usually in square feet, that they can effectively purify. If you’ve got a smaller room, a large air purifier will be overkill and may dominate your room. For large rooms, a smaller device won’t be able to purify the entire room effectively.

How effective is the filtration on my air purifier?

Not all air purifiers are created equal. Most will include a pre-filter to block larger particles, and most good ones will include a HEPA filter to trap smaller particles such as pollen and bacteria. Some will also include an activated carbon filter that can trap odours and volatile organic compounds (VOCs) which are chemical substances that can be harmful to your health. The more effective the purification, the more you’re likely to have to pay.
