Although it lacks a timer setting that would have allowed you to choose for how long the unit operates and a standby mode, it does come with other features that make it one of the best models on the market. The amazing Auto mode that this air purifier comes with keeps the air indoors contaminant-free without requiring you to change the operating settings as it detects the quality of the air by itself and adjusts the fan speed accordingly. Also, it features an air quality indicator light that changes colors according to the quality of the indoor air. This model comes with 4 different operating modes that you can choose from, more precisely Night, Silent, Fan, and Auto. Therefore, you get the chance to customize the air purifying experience in order for it to suit your needs and preferences.


The amazing Green Air Encore KH-H201 doesn’t only perform excellently, but it boasts a modern design that makes it a perfect fit for any decor. It comes in a single color option for the housing, the one that you can see in the picture above. The unit weighs only 16 pounds, and it measures 25 inches in height, 14 inches in width, and 7.5 inches in depth. Therefore, it won’t occupy a lot of space in the room where you place it, and it won’t be too hard to move from one location to another either as it doesn’t weigh much. Unfortunately, it does lack a certain design element that would have made it a more appealing option to go with, more precisely rolling casters. Nonetheless, this isn’t a major downfall because, as we have already said, it’s not too heavy so it won’t be hard to change its location whenever you want. Also, this model features a minimalistic design that makes it a dream come true for those who are looking for an easy-to-operate system. What makes it so great is the fact that it features a single on/off button, and it allows you to choose the fan operating mode that you prefer with a simple push of a button. Another design element that caught our eye is the fact that the light that it features changes colors according to the quality of the air in the room.
