Terrible product. I followed the instructions and ran it at full blast for a full 48 hours to get rid of the supposed VOCs "from packaging and shipping". Still the machine smells every time it is turned on and my whole room stinks. It gives me a sore throat and I wake up just as stuffed up as if there was no filter in the room. My existing cheap HEPA outperforms this device and actually detects particles/gases in space after using the Molekule! I am afraid for my health. i give it back It's flawed because instead of reducing odors and making me feel better, it did the opposite!
