1.What to Look for in an Air Fryer

Before you land on a specific air fryer, you need to consider a number of factors, including;

The Main Pollutants in your Home

The form of pollutants varies from one place to the other. The form of pollutants may also vary depending on the pets you own. 
For instance, if you are a pet owner, you need to go for an air fryer that will not be tangled with the pet hair and with a large dust tank to accommodate the pet dander.

Filtration System Efficiency

The efficiency varies from one air purifier model to the other; some brands come with HEPA filtration system that has 99.97% filtration efficiency, effective in capturing micro air particles with a size of 0.3 microns. 
If the air in our home has a bad odor, then you can go for an air purifier that is able to capture and eliminate odors.


An air purifier is considered convenient depending on the special features it comes with. On this factor, make sure you check features like the noise of operation level, filter life alerts, and sensors too.
You can also consider other factors like your room size, the cost of buying an air fryer, and the maintenance cost.
