A:Answer Yes. I have mine in my kitchen, which is 12’x15’ probably greater than 200 soft, but defiantly larger than 129sqft. I think the 129sqft is a recommendation, not an absolute, but I tihnnk having it strategically placed also helps; mine is place near the ceiling fan which helps to ensure that air is moving through the entire kitchen, but if I’m cooking something that tends to smoke up then I’ll move the purifier next to the stove, and it sucks up the smoke and produces clean air. I hope this helps.
