Questions about Mila?

We have answers here to help you out, or contact us.

  • How many Mila units do I need for my home?

    Air purifiers are like air conditioners: most rooms deserve both (eg., living rooms, bedrooms, studies). Each Mila covers up to 45m2 of space, so we recommend that you put more than one Mila in rooms significantly larger than 45m2.

  • I already have an air purifier – why do I need Mila?

    Unless your home only has one room, we recommend more than one air purifier. For instance, if you have a 2-bedroom home and one purifier in the living room already, sign up for a Mila Small Plan to filter the air in your bedrooms.
    You may also want to compare how much you’re paying in filter costs now with a larger Mila Plan :)

  • Where should I place my Mila purifiers in my home?

    We recommend leaving at least 20cm of space between your Milas and walls or objects that may impact air flow to and from Mila.

  • How can I pay for my Mila plan?

    We accept all major credit cards and debit cards. Our payment page shows the full list. We accept all major international credit cards for those with foreign passports; and we accept domestic payment methods (via UnionPay) for those with Chinese IDs.

  • What happens after my two year Mila plan ends?

    We show our appreciation for your continued support by giving you a discount! Your monthly fees after 2 years would be:
    Small: ¥150 | Medium: ¥225 | Large: ¥300

  • Is there a warranty?

    Yes. If you are having trouble with any of your Milas within two years, simply let us know and we will either repair or replace them. Email us at

  • Can I change my Mila plan?

    Yes! Adjust your plan anytime by going to your Account Page. Please note that reducing the size of your plan results in a cancellation fee of ¥20 per purifier per outstanding month (out of 2 years).

  • What do I do if I move to another address?

    Just send us your new address and we'll take care of it!

  • Can I order more Mila purifiers beyond your Large plan?

    Yes! Email us at and we will provide you with custom pricing options.

  • How do I cancel my plan? What is your cancellation policy?

    You may cancel your plan anytime and send your Milas back. Please check our Terms of Use for more details.

  • What’s your return policy?

    You may return your Milas within 14 days for a refund. Please send them back to us undamaged and in the original packaging. You will need to pay a small shipping and handling fee of ¥50 per Mila.

  • What countries do you ship to?

    Currently, we offer Mila air purifiers in Mainland China. Want Milas for your home market? Email us at

  • How do I set up my Mila purifiers and sync with my Mila mobile app?

    Please see our setup instructions.

  • Do I sync my Mila purifiers to my Mila mobile app one-by-one or all at the same time?

    You can do both. Once you download your Mila mobile app and connect to your WiFi network, the app will automatically detect all Milas connected to the same network.

  • How do I sync additional Mila purifiers to my existing Mila network?

    To add a new Mila, plug it in and go to Settings > Manage Units and tap the unit you wish to connect.

  • How much electricity does Mila consume daily?

    Keeping Mila on to monitor and optimize your home’s air quality costs less than ¥0.45 per Mila per day, about the same as a 30-watt lightbulb.

  • I’m having issues with my Mila mobile app. What do I do?

    Generally, we’d recommend you delete and reinstall your Mila app. That seems to do the trick in most instances. If you’re still having trouble, email us at and we’ll figure it out for you.
