Alen BreatheSmart FLEX Air Purifier

The BreatheSmart FLEX has one of the best sleep modes we have ever encountered. It produces a very soothing white noise that actually helps lull you to sleep while it purifies the air. This is a great purifier if you are prone to allergies caused by dust and pet dander. The true HEPA filter traps particles up to 0.3 microns in size and it is rated to purify air for up to 700 square feet of space. There are 4 fan speeds and the top-mounted handle makes it easy to move from room to room.

  • Great customer service from Alen
  • Consumes a maximum of 36 watts
  • You can actually choose from different Alen filters depending on your filtration needs
RabbitAir MinusA2 Air Purifier

This is a very quiet machine which makes it perfect for the 700 square foot rooms that it is rated for. It features a “pollen” mode that will automatically detect when there is too much pollen in the air and turn itself on. We thought it was really cool that you could mount this unit to the wall and that you can choose different artistic designs for the faceplate. We put it in our living room and we noticed that we were sneezing less and couldn’t smell any of the kitchen odors that usually waft into the living room.

  • Comes with wall mounts
  • The “pollen” mode is very accurate, intuitive and reactive
  • You can run it all day without much energy consumption
Alen BreatheSmart 45i Air Purifier

While this Alen model is very powerful and rated for rooms up to 800 square feet, it makes our list because it is surprisingly affordable. And after all, it’s better to have too much power than too little…so long as you don’t have to pay extra for it. This unit features side mounted air intakes and a fresh air distributor on the top so it can be tucked up against walls. We found this model to be especially useful for getting rid of allergens and musty odors in rooms that were prone to moisture buildup. It also runs very quiet in sleep mode and works well in auto mode.

  • Just over 2 feet high and 8 inches wide
  • Filters can be switched for specific needs
  • Ample power for an affordable price

Features to Look for in a Medium Room Size Air Purifier

Again, rooms around 600 square feet can be tricky. By and large though, you should look for the following features when selecting an air purifier for 600 square foot rooms:

  • An auto mode

  • Various timer settings

Benefits of an Air Purifier for 600 Sq. Ft.
