Benefits of owning a smart air purifier

Having an air purifier in your home gives you clean air to breathe. Adding in smart technology enhances its use, giving you more options. An app allows you to monitor the air quality in your home at all times, even when you’re away. Then you can adjust the settings as needed from anywhere. Some of the best smart home air purifier models are also able to link to an external device, like Amazon Alexa, which adds voice control to the functions. If you’re cooking, cleaning, or anything else, you can still manage your air purifier’s settings and speeds, even from another room.

Features to consider while choosing a smart air purifier

When in the market for a new smart air purifier, there are a few features you may want to check out before you buy one. Many of these are similar to regular non-smart models, with a few technological extras that add to their convenience.

Cleaning levels

Though you may see some dust particles floating around in the sun streaming in your window, most airborne particles are far too small to be seen by the naked eye. In fact, most of them are 0.3 microns or smaller, so a good air purifier must have a cleaning level to trap these unwanted nasties. All of the products we’ve reviewed above do trap those particles that are 0.3 microns or larger, so the dust, pet dander, and other allergens will be removed from the air.

Type of filters

When it comes to filters, there are three main types to choose from. High Efficiency Particulate Air, or HEPA, filters are the most sought after since they work the best. They are capable of removing 99.97% of the airborne particles that are 0.3 microns or larger. This includes particles like dust mites, pet dander, mold, or pollen.

The best air purifier for smoke removal should definitely contain a carbon filter. Activated carbon filters trap those unwanted odors and chemicals, such as smoke, cooking odors, volatile organic compounds (VOC) like paint fumes, or even pet odors. When the odors are removed, the air smells much fresher.

Many air purifiers also add in a pre-filter, which are the first filter the air passes through when pulled into the machine. They trap larger particles, keeping them off the other filters, prolonging their life and reducing replacement times. Many pre-filters are washable as well, so they also save you even more money in the long run.

Some air purifier models have one or two of these filters, but on smart models, you’ll usually find all three or even more. The Winix HR1000, for instance, boasts a pre-filter, a Coated Deodorization carbon filter, and a true HEPA filter for ultimate purification performance.

Fan speeds

Most of the air purifiers on the market come with at least three fan speeds. This helps you choose the speed at which the air is cleaned in your home. The higher speeds circulate the air faster, cleaning it at a much higher rate. This also raises the noise level, though, so high speeds are best used when you aren’t at home or in a different area of the house.

Low speeds are much quieter but don’t clean the air as quickly, so should be used to maintain air quality once the higher speeds have done all the work, or when you’re sleeping.

CADR

Clean Air Delivery Rate, or CADR, refers to the amount of air that can be filtered by an air purifier. There are three measurements that show the CADR. Tobacco smoke has a range of 10 to 450 CADR, dust has a range of 10 to 400 CADR, and pollen ranges from 25 to 450 CADR. If an air purifier has a rating of 100 CADR for dust, this means that the machine cleans the dust out of the air at a rate of 100 cubic feet per minute. The higher the CADR, the faster and more efficiently the air purifier can clean the air in that room.

Coverage area

The higher the coverage area, the larger the room you can use the air purifier in. For instance, the AIRMEGA 400S has a coverage area of 1560 square feet, so it will clean the air as it’s supposed to in a room of this size or smaller. If you tried to use it in a room that is 1800 square feet, though, it wouldn’t be able to perform as well since it would be forced to clean the air in a room that exceeds its capacity. Be sure to check out the size of the room you intend to use an air purifier in before choosing one.

Smartphone apps/Alexa compatibility

What makes a smart air purifier so smart is the technology used to run it. Most of the models above include an app you can use to link the machine to your phone, allowing you to track the air quality levels, change the fan speeds, choose a mode, or set a timer. Some of them also include compatibility to external devices, like Amazon Alexa. This gives you the ability to use voice control, telling Alexa to change the settings for hands-free use.

Dimensions

The dimensions of any smart air purifier don`t affect its usage, but it does affect where you can put it in your room. The larger it is, the more space it takes up, so a big unit won’t fit well in a small room full of furniture.

Be sure to measure the space you have available, then find an air purifier that will fit in there. It will need to be a few feet away from a wall, too, so be sure to take this into account.

Warranty

If your machine has defective parts or isn’t working the way it’s supposed to, repairs or a replacement will be a necessity. In order not to have to pay the costs for these issues, you should make sure your smart air purifier has a decent warranty covering any of these repairs. Most models do have warranties that cover any type of manufacturer or product defects, giving you free repairs or a replacement model if repairs aren’t possible.

Extra features

Though the main purpose of the air purifier is to clean the air, there are a few features that make them even better. A timer, like that seen in the Blueair Classic 605, lets you set it for a certain time period, so it will turn on even when you aren’t around. Remote controllers allow you to change the settings from across the room. Energy efficient certification ensures the machine won’t add too much to your energy bill each month. Sleep mode turns down the fan and dims the lights for a better night’s sleep. A filter indicator light tells you when it’s time to change them out. Child locks (like the one the Crane USA Smart Wifi Air Purifier features) hold the settings, even if little fingers start pushing random buttons.
