How to prevent dust from outside the window from entering the house

Preventing dust from entering the home through window screens can be achieved by installing screens, using air purifiers, regularly cleaning window frames, placing green plants, adjusting window opening times, and other methods.

1. Installing a screen can effectively block large particles of dust and flying insects from entering the room. It is recommended to choose a high-density dust-proof mesh. For residential buildings facing the street or near construction sites, double-layer screen windows can be installed in a stacked manner. The screen window needs to be disassembled and cleaned once a month to avoid dust accumulation affecting breathability. If the screen window is damaged, it should be replaced in a timely manner to ensure the filtering effect.

2. Use an air purifier [SEP]. Place the air purifier near the window to absorb the fine dust that enters through the gaps. Choosing a model with HEPA filter has better PM2.5 filtering effect, and it is important to regularly replace the filter when using it. It is recommended to keep it on during sandstorms or hazy days, and daily use can be combined with humidification function to reduce dust suspension.

3. Cleaning the window frame

The groove of the window frame is prone to accumulating dust and forming a secondary source of pollution. Wipe the window frame track with a damp cloth every week, and stubborn stains can be cleaned with a small brush. The pulley part of the sliding window can be coated with lubricating grease to reduce the debris generated by friction. Before and after the rainy season, it is important to check whether the sealing strip is aging and replace any hard or deformed rubber strips in a timely manner.

4. Place green plants

Place plants with wide leaves such as tiger skin orchid and green ivy on the windowsill, and their surface hairs can absorb some dust. The transpiration of plants can also increase air humidity and cause dust particles to settle. Pay attention to regularly wiping plant leaves with wet wipes to avoid dust accumulation that affects photosynthesis. People with allergies are advised to choose succulent plants with less pollen.

5. Adjust the window opening time

Avoid opening windows during rush hour or windy weather in the morning and evening, when the outdoor dust concentration is high. You can choose to ventilate when the air is fresh after rain, and open the window for no more than 30 minutes each time. Install adjustable angle windproof window hooks to achieve small angle ventilation. When going out for a long time, door and window sealing strips can be used to temporarily seal the gaps.

In addition to the above methods, it is recommended to clean the windowsill and nearby ground with an electrostatic precipitator mop every week, and remove and wash the curtains once a quarter. Newly renovated houses may consider installing a fresh air system to achieve filtered ventilation. Street facing residents can install dust-proof louvers outside their windows and cultivate habits such as changing shoes and placing clothes in different areas when entering, reducing dust from multiple dimensions. If there are people with respiratory sensitivity at home, professional indoor dust removal services can be provided regularly.
