Queues for N95 masks were still spotted outside pharmacies even as Singaporeans breathe easier in lighter haze conditions on Sunday.

At NTUC Unity pharmacy in the Tampines One mall, a queue of about 30 had formed by 1pm as customers jostled for stocks that had just been replenished in the morning.

"I had been trying to buy masks since last Thursday when the PSI crossed 300," housewife Madam Janet Soh, 49, said. "We only have one at home for my child and I'm buying for my elderly folk," she said, adding that she had left her name on the waiting list of several pharmacies.

About 15 people were spotted queuing for N95 masks at Watsons in Tampines Mall.

The Guardian Pharmacy branch near Toa Payoh HDB Hub still had stocks of N95 masks when The Straits Times visited at 11am. There was hardly a queue then.

A counter staff member at Unity Plaza Singapura said that stocks of N95 had run out and she was not sure when they would be replenished. Long queues at the outlet were spotted yesterday. Guardian Pharmacy at Tampines Mall also said that they ran out of N95 masks.
