Q:What is the relationship between the life of the filter bag and the dust collector?
High-temperature filter bag filter efficiency through the life of T0 bag is added to the established multiple is equal to the initial resistance according to the rated Q0 final resistance (usually 2 times) by the time, the quantity of dust at high-temperature filter bag filter, air filter has reached the maximum (also known as the standard amount of dust P0), so it can be considered the life of T0 high-temperature filter bag filter is the amount of dust HEPA filter to achieve the standard amount of dust P0 time. When the filter runs under low air volume Q1, at this time Q1 < Q0, so the filter life can be extended to T1, at this time T1 > T0.
Q:How can you remove the filter bags from Haier's little prodigy XQBM30-22 hand twisting automatic washing machine?

When the gas temperature is below 130 DEG C, the filter bag is selected at normal temperature, and the filter bag is used at high temperature between 130 and -260 degrees centigrade.2, gas humidity. Dust gas is divided into three states according to relative humidity: dry gas (relative humidity below 30%), general state (relative humidity between 30%-80%) and high humidity gas (relative humidity above 80%). When the gas humidity high should choose waterproof film bag.
