BANGKOK, THAILAND – Three years after Thailand ended all mask mandates in July 2022, nearly every local in the capital still wears one, citing pollution and public health rather than pandemic fear.
Official Policy vs. Public Practice
Thailand’s Ministry of Public Health confirmed that mask use has been voluntary since mid‑2022, recommending masks only for crowded or poorly ventilated places. Yet in early 2025, surveys in central Bangkok showed that more than 95% of residents continued to wear masks even outdoors and while driving.
Small businesses in areas such as Siam Square have adapted by selling decorated mask chains and designs costing between 5 and 200 baht each.
Air Pollution Crisis in January 2025
On 24 January 2025, the IQAir index measured PM2.5 levels of 108 micrograms per cubic meter, ranking the city the fourth most polluted worldwide. The Bangkok Metropolitan Administration reported that over 66,000 pollution‑related illnesses occurred between January and mid‑February 2025.
Government records show that since October 2024, 958,679 protective masks had been distributed to high‑risk residents across the capital, costing the state several million euros.
Infrastructure and Enforcement Measures
On 24 January 2025, Transport Minister officials announced the installation of 8 vehicle‑emission checkpoints across Bangkok. Public transport, including the BTS Skytrain and MRT Metro, was made free from 25 to 31 January 2025 at an estimated state cost of 140 million baht (about 3.5 million euros).
Cultural Context and Public Attitudes
Health researchers noted that a survey of 201 elderly Thais found 81.1% still wore masks outdoors due to perceived threats from COVID‑19 and dust pollution. In a country valuing collective responsibility, people often continue masking to protect others.
“Since I work in the service sector and deal with customers from many countries, I decided to keep wearing my mask even though it’s no longer mandatory.”

Foreign visitors often react with surprise. One travel writer observed:
“Years after the end of the pandemic, a large majority of Thais continue to wear masks almost everywhere they go.”

A tourist staying for two months in February 2024 described the same phenomenon:
“My husband and I are visiting Thailand for two months. There seem to be no restrictions, tourism feels normal, but many people still wear masks, especially in the metro or on ferries.”

Economic Consequences for Tourism
Before the pandemic, Thailand welcomed 40 million visitors annually, generating around 55 billion euros. Hotel industry representatives, including those from Sukosol Hotels, urged the government to enforce an air‑cleanliness law, fearing that images of masked crowds and smog could deter potential visitors.
Government Response and Funding
After criticism from opposition leader Natthaphong Ruengpanyawut, Prime Minister Shinawatra returned from the World Economic Forum in Davos on 25 January 2025 and promised budget allocations. The cabinet approved 620 million baht (16.5 million euros) for wildfire‑management programs at 1,800 sites in 14 provinces, plus an additional 1.1 million N95 masks for public use.
Chronic Pollution Sources
Data from the Pollution Control Department indicate that about 60% of Bangkok’s emissions come from traffic, followed by industrial and agricultural burning. During the dry season, from January to March, northern and central provinces experience dense smog as farmers burn fields.
Public Health Impact
The World Health Organization attributes up to 7 million premature deaths globally per year to fine‑particle pollution. Symptoms reported by Thai clinics include cough, shortness of breath, headache and eye irritation, particularly among the elderly and children.
Business of Permanent Protection
Thailand’s mask industry now produces millions monthly. Convenience chains like 7‑Eleven continue to display masks beside sweets and gum. N95 units, retailing for 30 to 150 baht, remain among the best‑selling protective goods.
Regional Comparison and Future Outlook
Neighboring countries such as Japan, South Korea, and Taiwan report continued mask use between 60 and 99 percent of citizens. With local pollution levels still above safe limits, officials from the Committee for Occupational and Environmental Diseases have designated Bangkok as a long‑term surveillance zone.
While mandates are gone, practical and cultural pressures maintain Thailand’s mask habit. For tourists arriving in Bangkok during the dry season, health authorities recommend checking air‑quality apps like Air4Thai or AirBKK and carrying N95 masks for safety.
