The O2+ Source utilizes a mesh pre-filter, activated carbon filter, and a True HEPA filter for its three-stage filtration process. To start with, its washable mesh pre-filter captures large airborne particles and helps to improve the lifespan of the activated carbon filter and the True HEPA filter.

Its activated carbon filter reduces odors, smoke, and harmful VOCs to ensure that the air in your room is fresh and free from bad smell. Lastly, the True HEPA filter removes airborne particles and allergens such as pet dander, dust, and mold spores to mention a few.

If you are looking for an easy to use air purifier, then you should consider the O2+ Source. It features intuitive controls and four different operating modes. In addition, the O2+ Source has an air quality indicator that adjusts the settings of the machine automatically to match the air quality of your room.

Furthermore, this unit has a filter change indicator that alerts the user to replace a worn out filter with a new one. This helps to enhance the effectiveness of the air purification process.

However, the sound produced is not irritating. In case you are looking for an air purifier that you can use in your office or bedroom, then the O2+ Source is a suitable solution for your air purification needs.

Users' feedback

Users quotes on Amazon.comI bought this air purifier because of my allergies first and foremost. It definitely does the trick. Good-bye hay fever. I also noticed that it has cut down on the amount of dust as well. Added bonus! Love the look of the machine and the convenience of the remote."

Users quotes on Amazon.comFirst, let me say that their customer service is terrific. The remote that came with the original package didn't work and they replaced it immediately after one phone call. Got the replacement in a couple of days. Now, as to whether the unit does what it is supposed to, I have to defer to my wife's experience. She says she sleeps better when the purifier is clearing the air, that it reduces nasal congestion, and she sleeps better. I'll verify she sleeps better. Does the unit actually reduce airborne particles? Hard to prove, due to variations in weather here in New England. Every day is a different day and often a different season. I'd give it a 5 if I could prove that it did clear the air. :) YMMV."
