Plasma Ion Technology projects positive and negative ions into the air to target and neutralise airborne impurities and pollutants for cleaner air. Advanced 3-in-1 filtration system: HEPA-13 filter captures 99.97% of dust, dander, pollen, allergens and other ultrafine impurities in the air; carbon layer in the filter helps reduce odours; antimicrobial coating prevents bacterial growth on the filter and protects it against degradation. Instant air purifiers also employ Plasma Ion Technology which is an ionizer in a nutshell. It produces negative ions which attach themselves to particles, making them bigger and easier to capture. The Instant AP100 is a small air purifier, so nothing surprising here. Works great for small rooms ~100 square feet like bedrooms and bathrooms. Useless for spaces over 200 sq. ft. Room Size for Large Instant Air Purifier Room size I have to be honest I never thought these things worked until I get this one. But I noticed a big difference in my allergies and my headaches since we have had it. It keeps the air at 99.9 until I open a door or window for a few minutes then I see how it really works. The air quality goes to 66.8 to around 77.5 with all the fires we are having right now.

Has an eco mode to save on energy– One of my favorite things about the Instant Air Purifier is that it has an eco mode to save on energy. When the air quality reaches it’s goal, it lowers the fan speed and adjusts how much energy it uses! To tell you the truth, Instant air purifiers is definitely far away from being quiet, especially at a higher speed levels. But here’s a good news: in Night mode the air purifier runs only at a speed one which produces white noise, but this white noise isn’t disturbing. I’ve put the small unit in my small bedroom and it didn’t bother me at night at all.
