An air purifier provides cleaner, healthier air in your home, ideal if you suffer from allergies or have pets. A smart version can be controlled via an app (also remotely) and gives you real-time insight into air quality. In this article, you’ll read all about how a smart air purifier works, how it differs from a regular air purifier, and what all the pros and cons are.

How does a smart air purifier work?

A smart air purifier basically works the same way as a regular air purifier: it draws in air, filters it with one or more filters (for example HEPA filters for dust, pollen and mould) and blows the cleaned air back into the room.

The difference lies mainly in the control and extra features. A smart air purifier:

  • connects to your Wi‑Fi network
  • can be operated via an app on your smartphone or tablet
  • can measure the air quality in your home and show it live in the app
  • automatically adjusts the fan speed based on the measured air quality
  • sends notifications, for example when the filter needs to be replaced.

This means you get the same purification functions as with a regular air purifier, but with more control, automation and insight via an app.

A smart air purifier mainly offers more convenience, control and insight than a regular air purifier. The key benefits are:

  • You get an overview of the air quality in your home.
  • You can control the air purifier remotely via an app.
  • You receive a notification when the filter needs to be replaced.

Overview of your home’s air quality

A smart air purifier continuously measures the air quality in the room and displays this data in the app. At a glance, you can see levels of dust, pollen or other pollutants in the space. In many cases, you can also see when the air quality gets worse, for example while cooking or during pollen season. This way, you know when and why the air in your home is less clean, and you can adjust your ventilation and air purifier use accordingly.

Control your air purifier remotely via the app

With a smart air purifier, you can manage everything from the app, even when you’re not at home. You can switch the device on or off, adjust the mode (for example, quiet at night or turbo when there’s a lot of pollution) and set schedules. This way, you can start purifying the air before you get home or automatically have the air purifier run more quietly when you go to sleep. You no longer need to use the buttons on the device itself to operate it.

Filter replacement notification

A smart air purifier keeps track of how long and how intensively the filter has been used and shows in the app when the filter is almost full. You then receive a notification that it’s time to replace the filter. This way, you don’t replace the filter too early or too late, and you ensure that its performance remains optimal.

What are the cons of a smart air purifier?

In addition to the benefits, there are also a few things to consider and potential drawbacks:

  • Privacy and security risks
  • Dependence on software and Wi‑Fi connectivity

Privacy and security risks

Because a smart air purifier is connected to the internet and exchanges data with the app and the manufacturer’s servers, privacy and security come into play. This means that information about your usage, location or air-quality measurements may be stored. If security is poor or passwords are weak, this can create risks, for example if someone abuses your network or account. It’s therefore important to use a strong Wi‑Fi password, install updates, and carefully check in the app which data you are sharing.

Software and Wi-Fi problems

A smart air purifier depends on stable software and a Wi‑Fi connection for full functionality. If the Wi‑Fi goes down or there is an issue with the app, some smart features may temporarily stop working. You can usually still operate the device using the buttons, but you lose functions such as remote control via the app or automations. A failed update can also cause problems. For that reason, check whether the air purifier is easy to use without the app as well, and try to install updates at a time when you don’t really need the device. Bovenkant formulier

A smart air purifier draws in air, filters it with filters (such as HEPA filters) and blows clean air back into the room. On top of that, it offers extra advantages compared with a regular air purifier, such as:

  • You can control it remotely via an app.
  • You can monitor your home’s air quality.
  • You can set up automations and adjust modes in the app.
  • You can integrate it into your smart home.
  • You receive in‑app notifications as soon as the filter needs to be replaced.
