Review on 🌬️ Future Lab N7S Air Ionizer - Portable Air Deodorizer with O3 for Home and Travel. Stackable with N7 to Eliminate Pm2.5, Odor, Cigarette Smoke, and Particles. Travel Deodorizer for Car, Office, Refrigerator, USB-Battery Powered. by Christie Santos

Laboratory of the future. N7S AIR PURIFIER, PORTABLE O3 AIR STERILIZER FOR HOME/TRAVEL Stackable: The laboratory of the future N7S is a small USB-charged portable ozone generator with a very quiet fan that circulates air through the device. According to Future Lab, N7S can produce 50 mg of ozone per hour and also [electrostatically] precipitate PM 2.5 from the air. You can stack several of these to cover larger areas or produce more ozone and ions, etc. Future Lab says they have other types of air filters that can be stacked. The N7S has two modes: Standalone and USB powered. If the device is charging when activated with USB connected, it will produce ozone and negative ions every 15 minutes (15 minutes on, 15 minutes off, continuous). The device is not connected to USB, while charging, it produces ozone and negative ions for 15 minutes and then turns off. The Future Lab says the N7S is effective up to 16.5m - 28m and is also moisture resistant and can be used to deodorize/sanitize enclosed spaces like a refrigerator. our large fridge as described by Future Lab and it worked great, the fridge smelled very fresh so we now use N7S in the fridge twice a week. We also use it regularly in large rooms, seems to work very well on its own and even better when we activate the N7S on a large round HEPA filter machine ('Bulex' sold by Revain) every few hours. In the photo I've attached you can see the Future Lab N7S in action on a working HEPA filter machine. I don't currently own an ozone meter, but I've done a lot of work in the field of electrostatics, and in my opinion the machine is clearly producing electrostatically high-quality O3 (ozone) in amounts approaching those claimed by Future Lab, you can smell the ozone, but it's moderate to light, not overpowering, smells very "fresh". I have a high quality Japanese Ion. a meter that measures both positive and negative ions per cubic centimeter of air (pcs/cm^3). left of the ion counter, the negative ion counter on the right. The N7S draws in air from all sides closer to the top, expelling ozonated and ionized air through the gap in the top (green glowing circle). CONCLUSION: Price/performance/quality is excellent, the Future Laboratories, O3 [Ozone] N7S portable air sterilizer does what it is supposed to and does it well. Superb quality construction (beautiful aluminum body). Logical and universal functionality. This machine works and is affordable, seems durable, highly recommend!
