TOSHIBA AIR PURIFIER CAF-Y33SG(W)
HEPA + ionizing function
less than $130, good for small living room or masterbed room.

works as well as many private-label $500 sets.

Check expiry dates before buying. Those with less than 1 years to expiry could be mouldy, even if they are from the hospital/MOH reserves.

N95 has at least 4-5 years expiry for most models. Eg. you pay the regular prices, can get 2027-2028 expiry. This is why don't consider those from shopee or lazada, many are old or counterfeits.
