Buying Guide: Smart Air Purifier
There are a lot of benefits to living in a big city, but polluted air is not one of them. The smoke from cars alone is enough to make most cities’ air harmful to breathe, and some effects of this pollution are immediate, like throat irritation, while others, like increased risk of asthma, take more time to surface. You can minimize these effects by wearing a quality face mask when going out, but that’s not a permanent solution. A better way to benefit from clean air is by buying a smart air purifier for your home.These purifiers not only rid the air in your home of harmful chemicals, but also remove unwanted odors, reduce dust, and make it more refreshing. Smart ones do all this completely automatically, which is why we’ve put together a list of the leading smart air purifiers in 2023.

Purifier Efficiency
Purifier efficiency refers to the amount of air a smart air purifier can filter in a given time, and this is usually measured in sq. feet/cycles per hour. These measurements also only make sense in relation to one another and should not be looked at on their own. For example, a purifier advertising 1,500 sq. feet of range might sound great until you read further and learn that it takes four hours to do one cycle in this gigantic area. Similarly, a purifier claiming to do five cycles per hour would be amazing in your home if it filtered more than 100 sq. feet at a time. An ideal standard for purifier efficiency is 1,500 to 1,550 sq. feet in at least one hour. On the other end of the spectrum, the smart air purifier you buy should complete at least five cycles in a 150 sq. feet room. Any purifier slower or less powerful than this standard is usually not worth your consideration.Purification Performance
Purification performance can be calculated by the cleanliness of the air after each filtration cycle. Most high-quality smart air purifiers claim at least a 99% purification rate, which sounds great, but the real performance metrics are much more nuanced than that. For starters, you need to know exactly which substances are being filtered. Quality purifiers are usually equipped with multiple filters to clean out substances like harmful gasses, pollen, dust, pet hair, and even microbes. Make sure the smart air purifier you’re buying filters anything you’re allergic to. As a side note, purifiers with odor filtration are generally more expensive than ones without this feature, but they can be worth the extra cost for folks who smoke or have active pets.Smart Features
Being “smart” is a big part of smart air purifiers, but what does “smart” mean in this context? The first smart feature you should look for is a cleanliness sensor. These sensors measure the quality of air around the filter and control its speed accordingly — a purifier with such a sensor should ramp up when you’re smoking, but slow down to a halt at night. This saves energy, reduces unnecessary noise, and makes its filters last longer.Another essential smart feature that air purifiers should have is smartphone connectivity. Mobile apps for smart air purifiers are great for monitoring the air quality in your home and the purifier’s power status, and they can also be used to control the purifier, ramp it up, turn it off, set timers, and activate its night mode.Cost
Most quality smart air purifiers will cost anywhere between $50 and $200 depending on their size, range, and features — anything below $50 is generally not worth your hard-earned money. Smart air purifiers above $200 can be worth the extra cost, though, if they include features like odor removal and washable filters.LEVOIT Smart Air Purifier
