The SmartMi 2 air air purifier has HomeKit smarts, UV sterilization, and good protection. If not for a messy setup course of, this could be an excellent air purifier so as to add to your own home.

Let’s break down the promised specs and evaluate them towards the smaller SmartMi P1.

For pollen, the SmartMi 2 has a clear air supply price (CADR) of 208 cubic ft per minute (CFM) versus 150 CFM on the P1. Smoke and dirt have the identical 196 CFM versus 130 CFM on the P1.

The SmartMi 2 is rated for rooms 279 to 484 sq. ft versus 180 to 320 sq. ft of protection on the P1. That offers some overlap in room sizes. When you’ve got a 300 sq. foot room you could possibly snug select both air purifier, although the SmartMi 2 has some benefits, different than simply being sooner.

Probably the most interesting advantages is the built-in UV mild. The ultraviolet mild is designed to kill viruses and micro organism within the air that’s trapped by the filter.

We cannot be testing this ourselves, however there are many research which have proven UV mild’s propensity for lowering micro organism and viruses — together with COVID. We do not have the instruments to successfully measure this ourselves but when all issues equal, we might desire a air purifier with UV sterilization versus one with out.

Design, filter, and setup

The SmartMi 2 air air purifier is only a hair over 22 inches tall, in comparison with the 14-inch top of the SmartMi P1. It has a good-looking darkish, metallic blue-grey physique that sits on a slightly-reflective mild gold base.

Don’t fret, we aren’t large into gold however the yellow hue is minimal, reflecting extra of the colours of the room round it. There are perforations across the backside two thirds permitting air consumption from all instructions which is then expelled from the highest.


On prime is a useful show that brings related info to mild. There’s a ring that encircles the data and modifications coloration based mostly on the air high quality, making it simply glanceable from throughout the room.

This ring combines the values from the TVOC and PM2.5 readings right into a generalized coloration worth. The ring can be ring if glorious, yellow if good, orange of reasonable, and pink if unhealthy.

There may be additionally what look so to be a model emblem of some type. It is not a emblem although, however as a substitute a pollen icon. This icon modifications coloration simply as the outside ring does, however is consultant of the PM2.5 and PM10 values which incorporates air born pollen.

Beneath the pollen icon is a readout of the present PM2.5 values. That is numerical for those who’d desire that over the color-coded ring. For TVOC, a single-bar bar chart graphically shows the info.

There are two capacitive contact buttons on the highest of the system, one for energy the opposite to cycle by way of the modes. With the button, you may cycle by way of sleep mode — lowest fan possibility for bedtime, guide mode for what you’ve got set within the app, and auto mode that throttles the fan up or down based mostly on the air high quality.

With the smaller SmartMi P1, you additionally had the power to cycle by way of the fan speeds which is one thing we might have most popular to see right here. If you wish to management the velocity in any respect by your self, you want to take action by way of HomeKit or the SmartMi Hyperlink app.


Upon receiving the SmartMi 2, you may be up and working in a couple of minutes. There may be numerous items of plastic and tape overlaying the completely different components it is advisable to take away.

That features the filter situated within the again panel. The filter is a cylinder that sucks air in from all 360 levels. The again panel has a deal with that you simply squeeze, letting it come free and pivot away from the physique.

When the filter is eliminated, a sensor mechanically shuts the air purifier off, stopping unfiltered air from working by way of the system or the fan spinning along with your hand inside.

As soon as the plastic is all eliminated, you may plug within the energy cable. It’s a customary polarized C7 AC energy cable. When plugged in, your present filter lifespan is displayed on-screen earlier than it begins filtering the air.

HomeKit management

With the addition of HomeKit, the SmartMi 2 integrates and performs good with all different HomeKit equipment. You’ll be able to embody it in scenes that automate it based mostly on quite a lot of elements or conditions.

Listed here are just a few examples of artistic HomeKit automations:

  • it could actually flip up or down relying on readings from different air high quality sensors in a room.
  • The air purifier can activate or off if you arrive residence or if you depart.
  • When the air purifier’s sensor detects poor air high quality, you may flip in your ceiling fan.
  • Sync a number of air purifiers in giant rooms collectively based mostly on their particular person readings.
  • Flip the air purifier down along with your goodnight scene so it is not as loud if you’re making an attempt to sleep.

The air purifier provides to HomeKit the way in which some other system does, no matter producer. You’ll be able to the HomeKit pairing code situated inside the filter cowl and it’s immediately recognized by the Dwelling app.

It then walks you thru the standardized strategy of including it to the community, assigning the system to a room, giving it a reputation, and toggling on any instructed automations. We added ours to our manufacturing studio the place we spend most of our sunlight hours.

Once you faucet on the accent, you may flip it on or off in addition to modify the velocity of the fan. When the fan was all the way in which up, the system would get noticeably loud.

Swipe up extra and also you get to all the system settings. Change the room or identify, add automations, and different preferences.

Technically, the SmartMi 2 provides as two equipment paired collectively. You’ve gotten the air purifier facet in addition to an air high quality monitor. The monitor gives you an outline of the air high quality — glorious, good, poor, et cetera — and the PM2.5 density.

You’ll be able to cut up these two gadgets to point out as particular person equipment within the Dwelling app, or depart them paired collectively.

Wonky integration

On the onset, our intention was to make use of the SmartMi 2 as a completely HomeKit system. That’s, to not depend on the third-party app for any further management.

A part of this ideology was for the sake of simplicity. Sticking to solely the Dwelling app was simpler than having to maneuver between two separate apps and is a perk of HomeKit equipment within the first place.

We plugged within the air air purifier and scanned the HomeKit pairing code moments later. The air purifier was added to the Dwelling app with out challenge.

However as the info started populating within the Dwelling app, the air high quality wasn’t listed. It merely learn “unknown” with out giving us a studying.

We knew the sensor and the air air purifier was fantastic as the present air high quality was displayed proper atop the system. There was the chance it simply wanted time to precisely measure the air so we let the machine run for per week earlier than making time to show again to testing.

Even after per week of working, the air high quality nonetheless was not displayed throughout the Dwelling app. Except for a full reset, we felt the subsequent possibility was to attempt the producer’s SmartMi Hyperlink app.

Once we launched the app, it required us to create an account. Thankfully, the app helps Signal In With Apple which does assist with privateness and reduces the necessity for yet one more password.

After creating an account and signing in, the air purifier didn’t mechanically present, regardless of already being on the community. After some fiddling and force-quitting the app, we had so as to add the air purifier manually. In doing so, we needed to reset the Wi-Fi.

We held the 2 buttons on prime of the system till the Wi-Fi icon began blinking and it shortly appeared within the SmartMi Hyperlink app. Then, the app requested us to re-enter Wi-Fi credentials.

This was a bumbling expertise and repeated the Wi-Fi course of that HomeKit had already facilitated within the background throughout the first pairing. As soon as this was performed, the air purifier profitable confirmed within the SmartMi Hyperlink app however appeared as “unresponsive” within the Dwelling app.

Now we have been left resetting the Wi-Fi as soon as extra, including it on to the Dwelling app for a second time. This time nevertheless, the air purifier was found as a HomeKit system and may very well be added to the SmartMi Hyperlink app with out the trouble of resetting.

At this level we had the air purifier in each purposes as we needed, and reflecting on the method it appears we might have had the perfect success initially if we might created a SmartMi account, added to HomeKit, then returned to the SmartMi Hyperlink app. A brand new firmware replace we put in may even have mounted a few of these odd onboarding bugs.

We do not go into these particulars for the mundanity of it, however reasonably to focus on the cumbersome processes that customers must undergo in troubleshooting connectivity points.

In any case this, we did efficiently get the air high quality to point out within the Dwelling app, for what it is value.

Residing with the SmartMi 2 air air purifier

Since we have been utilizing the SmartMi Hyperlink app, we bought to take a look at a lot of its further options, together with these not supported by HomeKit.

The Dwelling Display of the app exhibits the air high quality readings and visualizes the air and air pollution coming into the air purifier. A slider lets you shortly change modes.

Once you swipe up, you may see the filter age, display screen brightness, timer, and sleep timer. It’s also possible to allow or show sounds, little one lock, and the UV mild.

Within the app is the place you may view a graphical interpretation of the air high quality over time. You’ll be able to see it over the course of a day, week, or month.

As I discussed, we arrange our SmartMi 2 air air purifier in our studio, a roughly 400 sq. foot area. It would not be large enough to wash a complete basement, however rooms of twenty-two ft by 22 ft ought to be acceptable.

In comparison with the litany of different purifiers we now have in our residence, at max velocity, the SmartMi 2 is sort of loud. We actually would not have it working in our studio, bed room, or lounge whereas we’re there on the prime velocity.

As a substitute, we saved it at decrease speeds and solely ramped it up whereas we have been away from the home or there was some type of small or air challenge that required it to show up.

We have been very pleased with cleansing the air purifier as the skin can simply be vacuumed off and the highest of the air purifier is detachable, letting us wipe down the blades. This is likely one of the most user-friendly designs we have tried.

The filter it makes use of is a four-stage filter that features an lively carbon layer. This activated carbon may help alleviate smells within the air which is one in every of our largest considerations with so many animals.

HomeKit automations and routines labored completely, making this a stable air purifying answer — at the least as soon as we bought handed the awkward setup course of. We would love if SmartMi would permit firmware updates to be carried out by way of the Dwelling app, additional lowering the necessity for the SmartMi Hyperlink app.

Do you have to purchase the SmartMi 2

If this was a yr or two in the past, we might nonetheless most likely extremely suggest the SmartMi 2 because the variety of obtainable fashions was minimal. The VOCOlinc PureFlow by no means had substitute filters obtainable and the Molekule was small and costly.

At this level although, there are different decisions which might be seemingly higher choices. SmartMi has the smaller mannequin that we had no points with in any respect and its high-end Jya Fjord fashions. There are alternatives from Sensibo, Meross, and others to select from too, making it tougher to suggest the SmartMi 2.

The air high quality and setup points aren’t essentially the norm and we have seen a number of different reviewers don’t have any setup qualms. It may very well be fully one-off and never emblematic of different person’s experiences.

On a constructive word, as soon as all the things was linked there have been no different connectivity points and it was responsive every time we despatched a command by way of HomeKit. The UV sterilization is a singular impact that is much more necessary as folks start to assume extra about their well being.

Between the glossy design, HomeKit assist, inexpensive worth, and UV mild, it is value contemplating. The market is simply extra crowded than it was previously.

SmartMi Air Air purifier 2 professionals

  • Nice design with glossy, fashionable look
