Buying Guides To Choosing Best Smart Air Purifiers in 2021

Size and range

First and foremost, you need to measure the size of your room or house in order to choose a smart air purifier that fits perfectly in your room. There are large and small models of smart air purifier that you can choose from. Normally, a larger or more advanced model requires a bigger space to fit in. While at the same time, the smaller models only need a less big space to accommodate. But if you’re looking for a much larger one, a whole-house smart air purifier would be ideal for you. Aside from size, you should also consider portability, handles, weight, and wheels. Because these features help ease and fasten the air cleaning process, it’s also important to look for them when buying an air purifier. 

Filtering technology 

Having read the 10 best smart air purifiers above, you may have some ideas about different filters. Therefore, let us tell you once again about each type of filter used in a smart air purifier. First off, HEPA filters are the most common filters. This type of filter exists in almost every air purifier. This filter is made of cotton, foam, or fiberglass. Moreover, it can capture 0.3-micron particles very effectively. Next is Carbon filters. Typically, manufacturers use this filter along with other filters since it is excellent at absorbing fumes, odors, VOCs, and gas. Lastly, pre-filters are used alongside other filters too due to their ability in catching larger pollutants and improving the air quality. 

Noise level 

Generally, when shopping for a smart air purifier, you’ll see that most of them have 3 fan speed settings. And this setting determines the noise level of the smart air purifier. In fact, most air purifiers have 3 speeds (low, medium, and high), while some have 5 speeds. Henceforth, you need to be mindful of the fan speeds. Furthermore, you can adjust the speeds to match how much noise you don’t want to hear. However, please keep in mind that the faster the fan is, the louder the noise the level. 

Energy consumption

Home appliances consume energy since they need electricity to operate. Likewise, smart air purifiers consume so much energy. As a result, you might want to take into account the amount of energy a smart air purifier consumes before actually purchasing it. Typically, the energy most air purifiers use is between 5-200 watts. Most importantly, we strongly advise you to find a unit that is verified by Energy Star since it is cheap and energy-efficient. 

Maintenance

A smart air purifier is already so expensive. Consequently, you need to ensure that you know how much it will cost you in order for it to run smoothly. Since air purifiers require high maintenance in order to be long-lasting, replacing filters regularly is a must for all users. Thus, it’s necessary to think about the cost of maintaining your air purifier. 

Warranty 

To avoid unexpected or expected issues in the future, look for a smart air purifier with a warranty. Since products like air purifier is a long-term machine, you have to find the one with an appropriate period of warranty. In case some parts of the machine become defective, just contact the manufacturer.  Thus, you don’t need to purchase a new one.
