hello po! so far based on medical experts, di naman recommended yung air purifier at hindi pa nasuri if talaga may beneficial effects po sya sa loob ng bahay. pero we don't know baka somehow it helps. just remember, pinakaimportante sa lahat, handwashing, physical distancing, vaccination, healthy lifestyle po.
we dont use one ( thankfully we live in a well ventilated area) i think its beneficial if may history ng asthma or allergic rhinitis sa family since it lessens allergens and pollutants in air.
