In addition to complying with the basic elements and regulations of the vacuum cleaner, the car vacuum cleaner also needs to have the uniqueness of the car configuration.

1. Tightness

Sealing is more critical than suction. No matter how large the suction is, if the dust collector compartment is not well sealed, not only will it cause secondary pollution, the dust will continue to be sucked into the lungs. The key is to solve the tightness between the filter element and the server.

The edge is deliberately made into a curved surface, which enlarges the total contact area and bearing capacity of the sealing ring and the chamber body, and at the same time prevents the embrittlement of the vulcanized rubber. It should be understood that the service life of vulcanized rubber is shorter in the high-temperature natural environment of the car.

2. Filter quality

In addition to good airtightness, we also need to look at the quality of the filter. At this stage, popular car vacuum cleaners all use HEPA filters, which can filter out floating dust. However, with the increase in cleaning frequency, the actual effect of the filter will be reduced. Fortunately, it is removed. The replacement cost is not high.

3. Suction

If the car vacuum cleaner is not plugged into the car cigarette lighter to get electricity, or the built-in rechargeable battery is not used, the output power is not easy to be very large.
