In the past two years, the heavy smog in the northern region has come earlier than in previous years! The topic of healthy breathing has become the focus of everyone’s heated discussion.
Severely polluted weather, even if the doors and windows are closed, the indoor PM2.5 cannot be effectively reduced.
Therefore, in order to avoid respiratory diseases and pollution, air purification devices have become a necessity for many families.
Everyone has the experience of traveling on business and staying in hotels and guesthouses. May wish to recall, is there any traces of yellowing or even blackening around the air outlet of the central air conditioner of the hotel? This is the reason why the ventilation ducts have not been cleaned for a long time! We all know that the air conditioner in the home must be cleaned before using the filter and special cleaning Clean the inside of the hanging machine. Air purifiers also need regular maintenance!
While calling for the use of indoor air purifiers, experts made it clear that the results of inadequate maintenance and long-term non-replacement of the filter can cause the indoor PM2.5 concentration to exceed that of the outdoor nearly twice!
Air purifier body cleaning
Frequency: weekly or on demand
Tool: clean soft cloth
Note: When power off, do not pour water into the machine to cause the circuit to burn out.
1. Wring out the damp clean cloth, and wipe the body, air outlet window, and control panel as a whole
2. Open the front panel to clean, dry and reinstall
3. Take out the filter, pat it in a ventilated place, and place it in the sun for 4-8 hours. Do not wash with water
4. The clean brush cleans the odor sensing area to restore the sensor sensitivity.
Air purifier negative ion emitter cleaning and maintenance
Frequency: weekly or on demand
Tools: 2# oil paint brush or cotton swab
Note: Power off operation, check whether the oil brush head is firm, and avoid falling into the body.
Purpose: When the purifier is used daily, the positively charged dust, iron filings and other impurities in the air are easily adsorbed on the surface by the negative ion emitter, which produces a squeaky noise like an electric current, and reduces the noise after cleaning.
1. After power off, go through the air outlet and find the negative ion emitters on the left and right sides. The left transmitter head is located near the third row of holes just below the screws.
2. Deepen the oil paint brush into the air outlet, clean the negative ion emitters on both sides before and after taking it out.
Do not exceed the service life of the air purifier filter!
In addition to regular maintenance of the purifier, the air filter has its own rated service life (or according to the use environment and frequency), and it must be replaced when it expires!
Regular maintenance of the purifier is just like brushing your teeth every day. Dirt hidden in the teeth is not easy to see, and it is easy to breed bacteria. Regularly wash and brush to eliminate hidden dangers. However, don’t look at your teeth brushing twice a day. After a long period of time, there will be tartar and tartar. If you drink tea and coffee for a long time, you will easily turn black, so you need to wash your teeth.
This is like the saturation of the filter. Some problems can’t be solved by just washing and brushing. The teeth cannot be replaced with new ones, but the air purifier can be replaced with filters to ensure the highest efficiency of filtering indoor pollutants. What’s more, not changing the filter when it expires is comparable to chronic suicide!
The filter type purification method adopted by the air purifier. Since the filter uses a HEPA filter for filtering, the HEPA filter will gradually become saturated with the increase of adsorbed particles, and the dust holding rate will gradually decrease, resulting in a reduction in the efficiency of the purifier and energy consumption. Increase. At the same time, the particulate matter adsorbed on the filter is also a hotbed of virus and bacteria, which will multiply and breed bacteria. If the filter is not replaced in time, when the load of the filter reaches saturation, the original adsorbed harmful substances will be released, not only will it not rise. When the purification effect is reached, secondary pollution will also form. At this time, they are no longer guards of health protection, and become invisible killers that damage health!
How to judge whether the air purifier filter needs to be replaced?
The filters need to be replaced regularly, and the service period is generally about 8-14 months. The use environment will be different. In addition to the rated service life, it can also be judged by the filter status:
Filter combination screen 1: The surface of the screen is dirty and discolored, there are many debris in the small holes of the cold catalyst, and the internal activated carbon is obviously discolored;
Filter combination screen 2: Obvious discoloration or moldy, yellowing, and blackening on the surface. When the filter becomes dirty, discolored, yellow, or even moldy, the filter needs to be replaced in time.
It is recommended to replace the filter combination screen 1 and the filter combination screen 2 at the same time to maintain the best purification effect
