I became aware of Mila air purifiers in 2020, but the company was founded in 2015 in San Francisco. They certainly have top-end marketing skills, but their air purifier was only available directly through their website for many years. So, I got excited when I discovered it was available on Amazon a few months ago.
They use the simple filter technologies we care about here at HouseFresh with HEPA and activated charcoal, both of which have decades of science to back up their air-cleaning capabilities. Mila also allows you to customize your filter choice for specific situations like allergies, baby diapers and even VOCs from a home move.
Most air purifiers are simple devices, with smarter models allowing the device to turn on if it detects problems. The Mila takes this further, using its onboard computer to analyze your home air in real time. You can then enable the air purifier to work harder when you are not in the room to avoid higher speeds when you are close to it.
It even tracks your bedtime! You can enable a “turn down” that switches the air purifier on one hour before so the air is cleaned just before you go to sleep.
The downside is that they don’t come cheap, with the most affordable package costing upwards of $400 – for half the price, you will get better air cleaning performance with something like a Levoit Core 400S or even three Taotronics AP003, but I do think that the Mila comes with many quality of life upgrades and that some customers will prefer to pay a little more initially.
What’s refreshing about Mila is that they only have one model and recommend that customers buy extra units for more rooms or bigger spaces. Mila suggests one unit for any room you spend a lot of time in.
We updated our Mila air purifier review and posted it on YouTube, which has several updates over this current review.
The Lowdown on the Mila
If you only want the choice cuts and don’t want to read my full review (how dare you), then here are the key things from this review:
What we really like
What we think could be better
The specifications
This unit has a similar cleaning power as the Coway Airmega 150 or the Levoit Core 300S and can run fairly quietly at 37.5 dB at its very lowest. Electricity costs are optimal for a unit with this performance, but filter costs are slightly higher.

Stylish air purifier with Google Nest Thermostat bibes
The Mila is a good-sized air purifier that looks stylish.
Many top-performing air purifiers are large and hard to live with, with most of them needing wheels to be moved around the house due to how heavy they are.
No, that is not the case with Mila. We’re talking here about an air purifier with a low-height profile designed to be looked at.
Similarly to the Smart Air S, the Mila was one of the very few air purifiers I brought home that my wife liked the look of. With its wooden legs and its dotted body, this air purifier blends into our home décor in a way that most units don’t. You won’t mind keeping this air purifier on show like a smart thermostat or smart speaker.
The control panel sits nicely at the top of the unit, making it easy to control the different functions without the need to move the unit around. The touch screen is easy to use, with just three buttons: a Mode button in the center (o) and the fan speed controls on each side (- and +).
Even though you can select a Manual mode when tapping the Mode button (o), the Mila is a smart air purifier designed to get to work automatically without the need to make adjustments on the control panel or the app.
The moment you turn on the unit, the Mila will go into Calibration Mode before switching to Automagic Mode automatically. When in Automagic Mode, the air purifier will choose the fan speed automatically based on the air quality level detected inside the room:
But that doesn’t mean you can’t make further adjustments inside Automagic mode. There are seven unique settings housed under Mila’s Automagic mode:
As I mentioned above, there is also a Manual Mode available, which you will be able to choose by tapping the Mode (o) button and then tapping the (+) button to change from Automagic Mode (the default mode) to Manual Mode. You will need to tap the Mode (o) button one last time in order to confirm your selection.
When running your Mila in Manual Mode, you will be able to adjust the fan speeds manually by touching the (-) and (+) buttons. You will notice that each time you change the fan speed, the timer will also change according to the new calculations your Mila has made to figure out the estimated time it will take to clean the air based on fan speed and room size. Another thing that will change is the value for the “Target AQI” (the projected air quality index score under the new conditions you have set).
Personally, I would recommend you let the Mila decide what to do, as it is more than capable of figuring out what is needed based on its calculations. Plus, this smart brain comes at a hefty price tag, so you will want to use it if you have paid extra.
You will also be able to pair your Mila to your phone by using the Mila app. The process is simple and painless: you tap and hold the Mode (o) button for 5 seconds, open the app on your phone and connect to the network called “Mila Air Purifier” so you can follow further instructions.
This is where I feel in love with the Mila: I got the app to connect to my Android smartphone straight away, which is a rarity for other air purifier brands:
You can enable eight modes, each focusing on things like energy efficiency or sound levels and specific usage routines.
My favorite was a mode called “Bubble Boy Mode”, which is just a mode that instructs your Mila to keep the air as clean as possible at all times. Another mode I found myself using regularly was the “Housekeeping Mode”, which turns on the Mila automatically one hour before your bedtime to keep the air as clean as possible before sleep.
I liked that Mila shared the functionality issues of their device and app, from device pairing issues to device connections. They regularly update these issues at status.milacares.com. The fact that they share this publicly makes me feel confident that this is a core focus for them as a company.
Seven HEPA filter choices
When you buy a Mila air purifier, you will have seven filter options that use different HEPA types, from H12-H13.
Something I appreciated is that you can also choose the amount of activated carbon you want so you can tailor it based on the gasses and odors you need to tackle.
This way of using filters aligns with how we see the science of air cleaning with mechanical filters. Far too many brands like to make it sound like rocket science, but keeping the air clean is as simple as pushing it through two filters.
Here is a breakdown of the characteristics, use cases and prices for all seven Mila filters:
| Mila Filter | CADR | Filter Type | Good For | Filter Cost |
|---|---|---|---|---|
| The Basic Breather | 447 | H12 HEPA | 🚕 Pollution 🧹 Dust 🚬 Smoke | $74.00 |
| The Big Sneeze | 416 | H13 HEPA | 🌻 Pollen 🐈 Dander 🤧 Dust allergies | $84.00 |
| The Rookie Parent | 365 | H12 HEPA + 0.70 lb Activated Carbon | 🚕 Pollution 🧹 Dust 🚬 Smoke 👃 Odors 🧪 VOCs | $84.00 |
| The Critter Cuddler | 350 | H13 HEPA + 0.84 lb Activated Carbon | 🌻 Pollen 🐈 Dander 🤧 Dust allergies 👃 Odors 🧪 VOCs | $94.00 |
| The Home Wrecker | 300 | H12 HEPA + 1.96 Activated Carbon | 🚕 Pollution 🧹 Dust 🚬 Smoke 🐈 Dander 👃 Odors 🧪 VOCs ☠ Formaldehyde | $94.00 |
| The Mama-to-Be | 254 | H14 HEPA + 0.70 lb Activated Carbon | 🚕 Pollution 🐈 Dander 🌻 Pollen 🧹 Dust 🚬 Smoke 👃 Odors 🧪 VOCs 🔬 Ultrafine particulate (PM2.5) 🦠 Viruses and bacteria | $94.00 |
| The Overreactor | 254 | H14 HEPA + 1.25 lb Activated Carbon | 🚕 Pollution 🐈 Dander 🌻 Pollen 🧹 Dust 🚬 Smoke 👃 Odors 🧪 VOCs ☠ Formaldehyde 🔬 Ultrafine particulate (PM2.5) 🦠 Viruses and bacteria | $104.00 |
You can get filters that don’t have any activated charcoal. Still, I recommend that most people get at least some; otherwise, you cannot remove odors or gasses from the air.
The activated charcoal filter costs a little more, but I recommend it if you choose to use a Mila as your air purifier.
When it comes to replacing the filter in your Mila air purifier, the process is super simple and straightforward. Check out the video below to see how to do it:
As with all good HEPA-based filters, the filter is supplied in a sealed plastic bag, so you need to make sure that you remove these before you start the unit. Mila does an excellent job of explaining this common error that people make by making it clear with stickers on the outside.
The Mila cleared our test room in 35 minutes
We tested the ability of the Mila air purifier to remove particles from the air in the same room (our 728 cubic ft home lab) where we evaluate the performance of all our air purifiers. Our indoor sensor from Purpleair updates on PM1.0ug/m3, PM2.5ug/m3 and PM10.0 ug/m3.
We visualized the data from the Purpleair sensor so you can see how smoke pollutants were cleaned from the air from the moment we turned on the Mila inside our test room:
Air cleaning performance test results
With a CADR score of 146 CFM for dust, we expected similar results to the Levoit Core 300S, which cleaned our test room in 32 minutes. The final time for the Mila air purifier was 35 minutes, matching our expectations of the lab CADR scores.
The Mila can clean much quicker than a unit like the Levoit Core 200S, which has a CADR of 109 CFM (200.6 m³/h), and it took 61 minutes to clean our test room. So overall, even though it wasn’t the fastest unit to clear the incense smoke out of the air of our testing room, it performed better than the average across all units we tested.
Noise levels test results
On higher speeds, the Mila will go up to 59.2dB, which is not intrusive, but even so, in everyday usage, we found it rarely used this high power unless we were out of the room in automatic mode.
That said, we know that what we consider a comfortable noise level might be uncomfortable for someone else. Have a listen for yourself in the video below, where we show the different level of noise associated with running the Mila air purifier across each of its fan speed levels (when on Manual Mode):
The cost to run the Mila: $208.45 per year
1. Electricity costs = $58.45
Energy costs are rising worldwide and are certainly something to consider as many older units used to be 100W or more. Thankfully, the Mila air purifier has a 38.3 W max of around $60 a year, assuming it runs at full speed, which would be pretty unlikely unless you lived in a location with terrible outdoor air pollution. So, efficiency-wise, the Mila is good.
2. Filter costs = $150
The filters are replaced every six months and can be around $150-$200 a year, depending on your chosen filter. This is higher than average but not in the same realms as the IQAir Healthpro Plus, which has filters that cost $250 for just the HEPA element.
Bottom line
Overall, this is the first true “Smart Home” air purifier that does a great job of cleaning the air in your home. You have to know that it will mean paying more both in the long and short term, but it does come with many more features than your average air purifier.
At this price point, you could get a Coway Airmega 300S with higher air-cleaning performance, but it lacks many of the smart features you find with the Mila. Suppose you want smart features and a decent air purifier. In that case, the Mila is currently the top unit I recommend.
SOURCES
We calculated yearly costs associated with running the Mila Air Purifier 24 hours a day, 365 days per year utilizing the latest average energy prices as reported by the Bureau of Labor Statistics of $0.174/kWh as of May 2024.
