One such recently launched model is the Alen T300 air purifier. Built to clean rooms up to 300 sq. ft. in area, this air purifier is particularly effective against mold spores, pollen and pet dander. So basically it is successful in removing all the major particulates in the air. The added feature of this air purifier is that it comes with a UV light. So the problem of bacteria and viruses is also taken care of. It also comes with activated carbon filter to remove any odor that is present in the air.

The filters that come along with the purifier are pretty reasonably priced so it wouldn't burn a hole in your pocket if you have to buy one for replacement. The process of replacing is also hassle free and you wouldn't need to touch the pollutants that your previous filter has trapped.

The looks are also very appealing especially with the sleek design. While the most important thing about an air purifier is its performance it is also true that the looks matter. You have to keep it in a room and you can't cover it, so it should blend in wit the decor of the room and not stand out as one huge piece of mechanical junk.

The fan can run in four levels of speed and there is also an in-built twelve hour timer with it. The different fan speeds not only help you to conserve power and save on electricity bills but also lower the fan speed the less will be the sound produced by the unit.

There are also great value added features with this unit. It comes with filter replacement indicator, so you don't have to guess when you will need to replace the filters. It also comes with a digital display with touch button control. There is also a safety feature built into in by which the power will automatically be switched off if the cover is removed.

The unit comes with a life time warranty if you replace the filters regularly.

Although the Alen T300 works in a 300 sq. ft. area, it will be at its optimal efficiency level if the area of the room is 225 sq. ft.
