Best Smart Air Purifiers [UK Guide]

The indoor air around us can easily become dirty, contaminated with volatile organic compounds and vaporous chemicals that make their way inside our homes through windows and ventilation systems. Not to forget, the indoor furniture, plastics, paint, and floor – they all emit off-gas noxious fumes that choke our lungs and degrade our health.

Air purifiers provide a much needed solution to this, sanitising the air by removing these particles to provide fresh, breathable air. In this guide, we’ll share our recommended smart air purifiers, those that use a WiFi connection to enhance their feature set and integrate with the other tech in our homes.

What is a Smart Air Purifier?

Basics first, a smart air purifier works the same way as a normal air purifier. It purifies the indoor around you to help you breathe fresh air, free from any toxic gases. It can provide you with real-time feedback and lets you exercise better control over your indoor environment.

But a smart air purifier goes that one step further, utilizing a WiFi connection to provides you with accurate data on your room’s air quality and adding the ability to integrate it with schedules and routines that you have set up for your smart home.

Information is delivered to you via app in real-time, so you can detect the pattern of when the air quality index in your home is worst or better and plan accordingly, and often you can do all of this using just your voice thanks to voice assistant integrations.

Smart Air Purifier Buying Guide

To make sure that you choose the best smart purifier for your office and home, here are a few features to look out for:

Type of Filter

There are a variety of ways to clean the air in your home, so knowing what technology is used inside can make a difference. Here is a summary of the main filters:

• Activated carbon filter: This filter helps you eliminate airborne odors, chemicals, and gases. Being extremely porous, this filter is effective in trapping the odor and vapor molecules.
• HEPA filter: A true HEPA filter is capable of capturing microscopic features. It can trap 99.97% of particles that are 0.3 microns in size. So, if your home has visible smoke, allergens, dust, bacteria, mold spores, and pet dander – this filter will work its best to provide you with a breath of fresh air.
• Pre-filter: Having a pre-filter installed in your air purifier is necessary to keep its internal components protected. A mesh filter also extends the life of the activated carbon filter and True HEPA filter.

Square Footage Coverage

The number of square units that an air purifier can handle is called the square footage coverage. So, if you are placing an air purifier in your 6m x 6m living room, you should buy a smart air purifier with a square footage coverage of 42m².

Other important features that you can look for include – smartphone app support, Alexa or Google Home voice control, CADR rating (how well an air purifier can filter out smoke, pollen, and dust from the air), and so on.
