Poor quality filters are dangerous, so be careful when you buy them!

The authenticity of auto parts is not easy for non-auto repair industry people. Now the market is flooded with counterfeit and inferior goods, and the appearance of inferior products is almost the same as the genuine ones. It is impossible to distinguish between genuine and fake products. Many people, in order to save costs, have damaged other parts and caused unnecessary losses.

Dangers of poor quality oil filters

Poor quality oil filter hazards
1. Poor quality oil filter filter paper is of poor material quality, it is difficult to achieve the filtering effect required by automobile engines, and the filter area is smaller than the original oil filter, which has poor filtering efficiency and short service life.
2. Inferior oil filters often do not have bypass valves. Once the filter is blocked, the engine will not be able to obtain sufficient oil lubrication, which will cause the engine to jump teeth, burn out, or even be scrapped.
3. The inferior oil filter does not have the function of suppressing oil backflow after flameout, and the mechanical wear during cold start of the engine is increased, which reduces the life of the engine.
4. Poor quality oil filter rubber seals are of poor quality. The seals are deformed under high temperature and pressure, resulting in ineffective sealing and leakage of oil.

Dangers of inferior gasoline filters

Harm of inferior gasoline filters:
1. The filter element used for inferior gasoline filters is of poor material quality and poor filtering effect. Impurities in gasoline can easily block the fuel injection nozzles, resulting in increased fuel consumption, engine jitter, and severe fuel injection nozzle damage.
2. Inferior gasoline filter will make the fuel supply pressure unstable, the oil pressure is too low or too high. If the oil pressure is too low, the engine is difficult to start and the vehicle power is insufficient. If the oil pressure is too high, gasoline will not burn completely, the fuel consumption is high, and the three-way catalyst and oxygen sensor are easily damaged.
3. The filter element of inferior gasoline filter is not resistant to gasoline corrosion, and the oil path will be blocked after falling off, which will cause the engine to fail to start and the vehicle to break down, thus causing damage to the engine.

Hazards of Poor Air Conditioning Filters

Hazards of Poor Air Conditioning Filters

1. The inferior air-conditioning filter has a hard filter material, and often uses a single-layer filter, which is easy to block and has poor air permeability.

2. Inferior air-conditioning filters use poor bonding materials, are prone to cracking and damage, and have a short service life;
The distribution of activated carbon is not uniform, which cannot effectively filter toxic gases.
3. Poor quality air-conditioning filters have a poor effect in filtering dust and removing odors. Harmful gases in the air enter the car, causing damage to the human respiratory system and affecting physical health.
4. Poor quality air-conditioning filters can easily cause dust and foreign matter to accumulate on the evaporator, which can cause odors in the car.
