Air purifier has long become a modern family “breathing guardian”, but many people do not know is that this seemingly gentle machine once neglected to maintain, will be transformed into an invisible killer. Those adsorbed on the filter dust, bacteria, formaldehyde, if the long-term retention, like a time bomb, may be re-released into the air through the circulating airflow. Imagine, the family breathes every day, “clean air”, mixed with moldy activated carbon smell and breeding microorganisms, such a scene makes people shudder.
The essence of the filter is a cage of pollutants, but the cage also has a capacity limit. When the filter media adsorption saturation, the original PM2.5 particles will be intercepted like fugitives break through the line of defense, and humid environment breeding staphylococcus, Aspergillus will be more with the help of the filter hotbed crazy breeding. There has been a laboratory test shows that over half a year of service HEPA filter surface, the total number of bacteria can be up to 200 times more than the new filter. These microorganisms form bioaerosols under the impetus of the fan, which are particularly fatal to asthma patients and infants.
The acid reflux phenomenon of activated carbon filters often confuses users, but this is actually a signal of a chemical reaction between adsorbed moisture and pollutants. When the activated carbon content of more than 30%, although enhanced formaldehyde adsorption capacity, but also exacerbated the water vapor retention, the southern rainy season is particularly prone to triggering the filter moldy and sour. And clip carbon cloth structure of the low-end filter will accelerate the carbon powder slate, three months may lose purification function. Choose the honeycomb activated carbon structure of the filter, not only to ensure the adsorption efficiency, but also extend the service life to 12 months.
You can't rely on the indicator light alone to determine the life of the filter. Although smart models can estimate the remaining life through algorithms, variables such as ambient humidity and pet hair can affect the actual rate of decay. There is a simple way: mark the initial weight of the new filter with a pencil, weigh it every month to compare, and when the weight gain exceeds 80% of the factory labeled dust capacity, it must be replaced. If it is an old model, you can observe the air outlet air volume, when the maximum gear wind speed down 30% that suggests that the filter is clogged.
Replacement of the filter is a delicate work, power off after 10 minutes of static dissipation is essential. When removing the filter, be as careful as an archaeologist, especially for the model with snap-on design, the plastic parts may be broken if too much force is exerted. When installing a new filter, pay attention to the airflow direction marking, reverse installation will lead to pollutants through the filter material. Here's a pro tip: Putting a layer of old stockings over the primary filter can trap large hair particles and extend the life of subsequent filters].
Special environments require special measures. In coastal areas with high humidity, it is recommended to take out the filter and dry it in the shade for 6 hours every month, and in dusty weather in the north, it is necessary to add a dust cover to the air inlet of the purifier. Families with smokers or pets can add a photocatalyst filter after the activated carbon layer to continuously break down organic pollutants using ultraviolet light]. Excitingly, Samsung's latest Bespoke series has achieved filter replacement-free technology, reducing maintenance costs by 70% through a combination of washable dusting mesh and UV regeneration deodorization module].
Recycling of filters also requires environmental awareness. Discarded HEPA filters need to be packaged in sealed bags and disposed of as hazardous waste, while activated carbon filters can be cracked and buried in the bottom of flower pots as a breathable material. Remember, regular maintenance is not only to protect the machine, but also to guard your family's health defense. The next time you hear the purifier noise becomes louder, do not simply lower the wind speed, that may be the filter issued a distress signal - timely replacement, in order to make every breath truly at ease.
