How to Connect Any Air Purifier to Alexa and Google Home/Nest Devices

Connect Air Purifier Alexa Featured

If you recently purchased a Philips, Levoit, Mi, Winix, Dyson, or any other modern air purifier, there is a good chance it can be connected to your phones and tablets. Here’s a basic guide that shows you how to do it for Amazon Alexa and Google Home apps on iOS and Android devices. Once you successfully pair the apps, you can further control the air purifier using your own voice on Echo, Google Home and Nest range of speakers.

Is My Air Purifier Compatible With Alexa or Google Home?

While browsing smart purifiers online, always look for “Works with Alexa” or “Hey Google” symbol in the product specs. If your HEPA filter-based air purifier is compatible to work with Amazon Alexa or Google Home, it would indicate high product quality with better functionality.

Air Purifier Connect Works With Alexa While Buying

You can check whether your air purifier supports either Alexa or Google Home from the manufacturer app mentioned in specs/instructions manual.

We will demonstrate the key steps common to connecting Alexa and Google Home to any generic smart air purifier model.

1. Power On Your Smart Air Purifier

The first step is to power on your air purifier by following the manufacturer instructions manual. It should directly connect to a wall socket or other plug point, but in some cases, you might require a Wi-Fi smart plug to enable “smartness.”

All air purifiers have a visible or hidden ceiling fan to accumulate the pollution particles such as PM 2.5, molds, and bacteria, trapping them inside the HEPA filter. After you power on the purifier, the fan starts its operation.

If you’re setting up the air purifier for the first time, you might find the Wi-Fi symbol disabled or missing. This is perfectly normal. The device doesn’t know there is Internet in its surroundings. That’s why we need a companion app to establish the Wi-Fi pairing.

No matter the air purifier brand, use a companion app provided by the manufacturer to insert the purifier into your network.

Frequently Asked Questions
