Preparing Your Home for Tet: Clean Air for a Healthier New Beginning

As Tet approaches, households become busy with cleaning, decorating, and preparing meals for family reunions. It is a time of renewal, togetherness, and fresh starts. However, what many people don’t realize is that this period of preparation can also increase indoor air pollution, quietly affecting the air we breathe at home.

When holiday traffic brings outdoor pollution indoors

In the days leading up to Tet, traffic volumes rise significantly as people travel and return to their hometowns for the holiday. Increased vehicle emissions led to higher levels of fine particulate matter (PM2.5) and other airborne pollutants in outdoor air. These microscopic particles don’t just stay outside. They can enter homes through windows, doors, small gaps, and ventilation systems, even when doors are closed. As a result, indoor air quality may deteriorate without any obvious signs, as fine particles and harmful gases are invisible and often odorless.

House cleaning – when invisible fine dust is stirred up

Deep cleaning is an essential part of Tet preparation. Activities such as sweeping, wiping surfaces, washing carpets, and rearranging furniture help create a fresh and welcoming home. However, these actions can also disturb settled dust and fine particles, causing them to become airborne and remain suspended for hours after cleaning. During the days before Tet, cleaning often happens more frequently and over longer periods. Without proper air quality control, indoor PM2.5 levels can rise above normal, increasing exposure to airborne pollutants for everyone at home.

Tet cooking – an often-overlooked source of indoor air pollution

Alongside cleaning, increased cooking activity is another major factor affecting indoor air quality during Tet. Preparing holiday dishes often involves frying, grilling, simmering, and long hours in the kitchen, all of which can generate smoke, odors, and ultrafine particles. In enclosed kitchens, these pollutants can accumulate in the air, leading to discomfort and respiratory irritation. This is especially important for households with children, older adults, or individuals sensitive to smoke and strong odors.

Take control of your indoor air with AirVisual Pro

Protecting your home during Tet starts with understanding your air quality. AirVisual Pro allows you to monitor indoor and outdoor air quality in real time, clearly displaying key indicators such as AQI and PM2.5 concentrations. With this information, you can easily identify:

• When outdoor air pollution increases due to heavy holiday traffic
• When indoor PM2.5 levels rise during cleaning activities
• The impact of smoke generated during cooking

Access to real-time air quality data empowers you to adjust daily habits and activate air purification at the right moments, rather than reacting only after discomfort appears.

Effective air purification with the HealthPro 250 XE

Monitoring air quality is only part of the solution. Effective air purification is essential during the Tet preparation period. The IQAir HealthPro 250 XE is designed to efficiently remove PM2.5, viruses, bacteria, and common allergens, helping maintain clean indoor air even when outdoor pollution levels are high. With its advanced filtration performance, indoor air is continuously purified, allowing every family member to breathe comfortably and fully enjoy the Tet season.
