Repair Air Purifier How To Do?


You can improve your air quality with an air purifier. There are numerous types created for different kinds of pollutants. Once you have an air purifier, there are ways to check to be certain your unit is performing correctly and effectively.


We recommend purchasing an air purifier with a filter indicator light. Every type of air filter will become less effective with age. This means the contaminants are not being removed from your indoor air. You will eventually need to replace your filter or your air purifier will not work.

When you purchase a unit with a filter indicator, the performance of your filter is measured. When your filter is no longer effective, a light will come on. This is the easiest way to know when to replace your filter. If your air quality does not improve, your air purifier needs to be repaired.


Whether or not you have a filter indicator, we also recommend manually checking your air filter. It is possible your unit can be giving you a false read. You should manually check your filter on a regular basis. This is even more important if you believe your air purifier is not performing at optimal efficiency.

Take a good look at your filter for any dust, hair or debris. If your filter is not clogged or is extremely dirty, you will not need to replace it. This method can only be used if you have a HEAP purifier. You will not be able to determine if a carbon filter is dirty or clogged.


There are smart air purifiers available with numerous advantages including HEPA filters, apps and sensors. You will be provided with air quality reports every minute, stats, alerts and graphs. If your air purifier reports are poor, there is a good chance you need to replace your filter.


Pay attention to any allergy symptoms you are experiencing inside of your home. Symptoms such as headaches, itchy or watery eyes and a stuffy nose can indicate your air purifier is not working properly. When the air in your home is correctly purified, most if not all of your symptoms should be eliminated. Whether your allergies occur seasonally or throughout the year, they can be triggered by pet dander and dust.

An air purifier is effective because even extremely small particles are removed from your indoor air. This will improve your comfort level during the day or when you are sleeping, and it can eliminate your allergy symptoms when you are at home. If your air purifier is not performing correctly, we recommend having your unit repaired.


To determine if your air purifier is working correctly, we recommend checking the airflow coming out of your unit. There is a fan in your air purifier responsible for pulling in the air inside your home. Harmful pollutants are trapped in your filter, enabling the device to blow clean air into your home. If you do not feel any air coming out, there is an issue with your unit.

The fan inside of your air purifier should be running smoothly and fairly quietly. If you hear loud noises, either you need to replace your filter, or your unit requires repair. Your device should not be completely silent. If this happens, the amount of air being pulled in will not be enough to improve the quality of your air. If your fan is not moving at all or is moving extremely slowly or roughly, your device needs to be repaired.


One of the best benefits of an air purifier is the elimination of distasteful odors, including smoke, trash and dirty diapers. If you can smell odors in your home, there is an issue with your air purifier.

The air purifier is mainly composed of a motor, a fan, an air filter and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine to remove various pollutants. Or adsorption, some models of air purifiers will also be equipped with a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), which continuously ionizes the air to generate a large number of negative ions, which are sent out by the micro fan. The formation of negative ion airflow achieves the purpose of cleaning and purifying the air.

The power indicator is off, and the fan does not rotate. First check the power transformer and fuse. Use a universal meter to measure the resistance to see if the coil or fuse is burned out. If it is short-circuited, replace the similar transformer or fuse in time.

Fire between the two poles of the negative ion generator. The positive and negative plates are bent and deformed and rubbed, or the air humidity in the operating environment is too high, which will easily cause the negative ion generator to ignite. You can use pliers to check and correct the pole piece. If there is no response, you can move the air purifier to a place with dry air for a short period of time, which can usually be solved.

The power indicator light is on, but the fan does not rotate. The power indicator light is on to indicate that the high-voltage circuit is normally energized, and it may be that the fan is malfunctioning. First check whether the bearings are severely worn and whether there are foreign objects in the fan blades. If there is no problem, use a multimeter to measure whether there is a circuit break in the circuit of the motor. If there is a circuit break in the motor unit, replace the fan motor of the same specification.

The negative ion output concentration is low, and the purification effect is reduced. There are many factors for the low concentration of negative ion output of the air purifier, which may be excessive dust and dirt on the electrode and filter, bending and deformation of the positive and negative plates, or the high voltage is too low. First, clean up the dirt on the electrode and filter, check and correct the positive and negative plates, if there is no effect, then check the high-voltage circuit. Use a multimeter to check the rectifier tube, step-up transformer, capacitor, etc.

Although our living standards have been greatly improved, the problem of air pollution is very serious. Long-term exposure to a polluted environment will also threaten our health. Therefore, more and more people use air purifiers. Too much, the purification effect of the air purifier is ideal, and it can be used in many places. When the air purifier fails, we should not blindly repair it. First, we must troubleshoot the failure to find the cause of the air purifier failure. Then repair the air purifier in a targeted manner so that the air purifier can be repaired quickly and the air purifier can return to normal operation.
