10 Best Smart Air Purifiers (2022)

Do you know that there are more impurities in your indoor air than the outdoor air? This is because indoor ventilation circulates the same air over and over re-introducing the same impurities into the air. If you have a potted plant in the house, that can be beneficial for the purification of the air. But the best smart air purifiers not only cleans the  air in your house  but also removes harmful particles like allergens.

Air purifiers suck the air into the unit which has a series of fans. The fans push the air through filters that clean out the air as it passes through them. The cleaned air is released back into the room and the unit repeats the same process after a few hours maintaining clean air throughout. The best thing about modern air purifiers is that they are quiet enough and dark so that you can use them in your bedroom as you sleep and they are also efficient enough to clean volumes of air consistently.

Frequently Asked Questions

a) What impurities can be found in your house?

The chemicals that man-made materials emit in the form of off-gases when one is building or even insulating a home. Some of the toxins released into the household include benzene, carbon dioxide, formaldehyde, and trichloroethylene. These are responsible diseases like cancers and liver disease among others. Unfortunately, no plant can eliminate tobacco smoke and other fumes. Plus, you need one plant for every 100 square feet of space. A rough estimate shows that you need 18 plants for 1800 square footage.

The good news is that air purifiers help to get rid of tobacco smoke, smoke from cooking, perfumes, hairsprays and pollen among other particles. They also prevent contamination of the air when you open the windows. Space, where you have created a conducive environment for clean air, gives you peace of mind and a definite healthy body.

b) How often should I run my air purifier?

Air purifiers will need to be run constantly and for those who prefer it they can be run continuously. An hourly schedule programming of the unit allows it to run automatically. We recommend a constant and consistent schedule because the impurities in the air get re-introduced back when you switch the unit off. For people with large spaces, you can consider an air-purifying system that can clean the whole house. But for smaller spaces, a portable unit in key rooms will work just fine.

c) Why do I need an air purifier?

The air purifier offers users many benefits including removing harmful particles from the air they breathe like seasonal pathogens, neutralizing smoke which stinks up space and keeping the air fresh at all times. Overall, an air purifier contributes to your good health by providing you with clean, healthy air.

What to Consider When Shopping for an Air Purifier

i) Size

There are two sizes to consider here: the size of your space and the size of the purifier. You will generally find air purifiers to cater for different spaces depending on the square footage of the space. The smallest air purifier you will find is made for a space of up to only 299 square feet.

The next size caters to a space of between 300 and 699 square feet. This is followed by a unit that caters to space between 700 and 1900 square feet. The final size is more of a system than a unit and this cleans the whole space regardless of the size.

ii) Features

The basic features on most air purifiers include the fan speeds, filter change indicators, and programmability. However, you can look for special features to make using the unit more convenient for you. For example, look for features like remote programmability and using a WiFi signal. These features allow you to adjust the purifier remotely.

Other features to consider include real-time updates from the air purifier on the state of the air quality in your space. This ensures that you know exactly how healthy the air you are breathing in is at all times. We recommend buying a unit that is Energy Star rated to keep your energy costs down. A few added bells and whistles like wheels, remote controls and handles for portability are also worth considering.

iii) Maintenance

Look for units that are low maintenance meaning they need fewer replacement parts. But the truth is that with air purifiers there are many replacement parts. Just find a unit with parts that can go for longer before they need replacement. Parts like the filter can be washable giving them a longer service life, or you can consider HEPA filters that last up to five years.

Other options use ultraviolet light or heat to purify the air. This guarantees even better chances of killing off the germs and pathogens in the air.

iv) Ease of use and cost

Look for units that are easy to use. Since this is a daily use device, a complicated model will take time to set up and time to get it up and running daily. When it comes to cost the more expensive the model is no guarantee that it is the best option. Opt for something within your budget range as long as it is effective and provides you with the results you are looking for. Most air purifiers offer decent service and are adequately efficient.


An air purifier is an effective way to get clean fresh air in your space. You can live in a germ-free environment as long as you choose the right air purifier for your needs. Here is to clean, healthy air!
