HomeKit Weekly: Meross Air Filter Can Keep Your Room Air Clean With HomeKit Automations


Air filters are something that I believe should be in every home. Even in my hometown of Chattanooga, Tennessee, where the air is generally clean, there is a lot of pollen in the air at different times of the year. If you live in an area that has experienced constant forest fires, you need a healthy supply of air filters even more than I do. However, there haven’t been many options for HomeKit-compatible air filters. Until recently, the only option was the VOCOlinc air filter. Although I like this product, it has a large footprint so it is not practical for apartments or small bedrooms. I recently purchased the Meross HomeKit air filter for our bedroom, and it’s a great option if you need to filter the air in a smaller area.

HomeWeekly Kit is a series focused on smart home accessories, automation tips and tricks, and everything related to Apple’s smart home framework.

The VOCOLinc option is designed to clean the air in a 645 square foot area, while the Meross is designed to clean a 207 square foot area, so you can see that it will cover a much smaller space. Therefore, I recommend the VOCOlinc option for a larger bonus living room / room where the Meross will be perfect for a bedroom or the living room / central area of ​​an apartment.

HomeKit integration

Adding the Meross air filter to HomeKit was a snap, as it is with all of the Meross products that I have reviewed in the past. There is a HomeKit code on the side, so once you scan it, it will allow you to add it to a room and activate some predefined automations.

The Meross option excels over the VOCOlinc is the data displayed in the Home app. With VOCOlinc, you will only have basic product information. With Meross, you will see the status / life of the filter in the Home app so you can monitor the need for replacement.

We usually run the air filters at night to create white noise in our rooms, so I have set the automations to turn on at 11 p.m. around the time we usually retire for the evening, but we do a manual shutdown in the morning.

Material quality

The size of the Meross air filter is perfect for a bedroom, and it would easily fit next to / under a bedside table. My desk is in our bedroom, so I slide it under.

The metal case is solid and I also appreciate the child lock option to prevent our kids from accidentally turning it on. The air filter includes a replaceable filter and new ones should be purchased every three to six months (depending on your air quality).

Suggested HomeKit automations

Light up in the bedroom

To activate a light up in the bedroom automation: launch the Home application> Automations. Choose what you want to trigger automation. For this example, choose a time of day. Select your time and days of the week. If you want to use a different bedtime on weekends than on weekdays, you will need to do this process twice.

Find the Meross air filter and then activate it. I configured it to turn off after four hours in my automation to save filter life.

Using Siri

If you have a HomePod or HomePod mini, you can use Siri to activate the air filter on demand. For example, say, “Hey Siri, turn on my master bedroom air filter.” Change the name of the room depending on where you are using it.

Based on movement

If you have a HomeKit motion detector, you can trigger the air filter based on someone entering the room. In the Automations section, choose A sensor detects something to choose whether to activate something when it detects motion, find your motion sensor, and then set your options. In this situation, it may be a good idea to turn it on for 30 minutes whenever it detects movement.


The Meross Air Filter with HomeKit is a great addition to your smart home with its small footprint, manageable cost, and ease of use. The quality of the air you breathe is important, and running air filters throughout the day is an easy way to improve the quality. Having everything run through HomeKit makes it even easier to use.
