One, can anti-dust screens prevent dust?
Nowadays, the mesh fabrics available on the market are made of polyester mesh and core membrane. Polyester mesh is a filtering material used for medical examinations, while core membrane is a new type of microporous filter membrane that was developed in the 1970s in foreign countries. Therefore, dust-proof windows can effectively block atmospheric pollution and PM2.5, thus maintaining fresh indoor air.
However, consumers should not blindly trust the dustproof effectiveness of the mesh, as some merchants may exaggerate the facts to attract customers. For example, claiming a filtration rate greater than 98% or a ventilation volume of 0.9 cubic meters are often misleading.
Two. What mesh size is suitable for dust-proof windows?
Due to the different materials and technical specifications used in the production of various dustproof window screens, there is no definitive standard for the mesh size of window screens. However, generally speaking, the larger the mesh size, the smaller the holes, and the better the dustproof performance, while the breathability will be poorer.
Three, Key points for selecting dust-proof windows
1、Inspect the mesh
Common types of dust-proof windows currently available on the market include those made from chemical fibers, glass fibers, and plastics. When selecting, it is advisable to choose windows made from chemical fiber material, as they can withstand thousands of opening and closing cycles without deformation. Additionally, check the uniformity of the mesh and ensure that the fabric has a slightly rough texture when touched.
2、Construction of screens
Actually, the construction of window screens directly affects the product price. I suggest that friends use aluminum alloy-based panels because they are prone to deformation and have a short lifespan when exposed to direct sunlight. When selecting, it is also advisable to manually press or shake the window screen to assess the hardness of the profile; it should be firm.
3、Window sash bearings
The quality of this component directly affects the operational efficiency. It is recommended to use fully enclosed, silent bearings, as open bearings are prone to dust accumulation. Additionally, check if it includes guide rails and locking pins. Without these, the material can be easily blown away by strong winds, allowing insects to enter.
