People spend most of their time living indoors, especially during the epidemic, when many office workers work from home. Indoor air quality is particularly important.PM2.5 sensors and formaldehyde sensors are used in air purifiers to help you solve indoor air pollution.
Classification of indoor air pollution
There are many sources of biological pollutants in the air, such as allergen substances, such as pollen, dust mites and animal dander.Hair and dander from us or our pets can easily show up on seemingly clean carpets, sofas and bedding in our homes.If not cleaned promptly, it will breed dust mites that feed on it.
Bacteria are also typical of biological contamination.We all know that moist environments breed bacteria.Bathrooms, kitchens, and shaded balconies in your home are actually where bacteria like to grow.Not only do these bacteria stick to surfaces, but as indoor air moves, some of them spread throughout the room.
Physical pollution in the air of a home usually refers to dust pollution, such as dust, smog and droplets, the most well known of which are PM 2.5 fine particles.Although we advocate not going too far in particular times.But when we have to go outside, our masks, clothes, soles and used mobile phones can bring all kinds of bacterial dust indoors and release it into the home.
Formaldehyde is the main volatile gas in indoor air pollution.Formaldehyde isn't limited to new homes.In addition to decoration, it is widely used in our daily life.Formaldehyde is used in many everyday cleaning chemicals, cosmetics, sofa fabrics, textiles and even food preservatives.Even if it is not a new house, many wood-based panels will slowly release formaldehyde within 3 to 15 years after decoration.Especially in a heated or air-conditioned room, formaldehyde tends to evaporate more easily as the temperature in the room rises.If we don't open the window often, the indoor air environment at this time is very unfavorable to us.
So even though we have a lot of air pollutants in our homes, we hardly see them.But being invisible doesn't mean you can rest assured that the hazards of air pollutants can't be ignored.Air pollutants such as dust mites, formaldehyde and PM 2.5 not only affect our respiratory health, but also contribute to bronchitis and other lung diseases.
How to solve indoor air pollution
In addition to daily ventilation, try not to smoke indoors, preferably with an air purifier.When choosing an air purifier, the filtering capacity of particulate matter and formaldehyde are two hard indicators to check.In the air purifier, PM2.5 particulate matter sensors and formaldehyde sensors are mainly used to monitor the concentration of particulate matter and formaldehyde in the room. Once the concentration changes are detected, air purification is required.
For the selection of PM2.5 sensors in air purifiers, LUFTMY recommends the use of LD13 laser PM2.5 dust sensor, which can measure tiny particles above 0.1 micron, can sense the smoke and pollen produced by tobacco, house dust, etc.Small size, light weight, easy to install, widely used in air purifiers.
