How to know when to change the vacuum cleaner filter

November 15, 2022

The dust collectors and industrial dust collection systems after some time need to be replaced with new filters. So how to know when to change the filter for the vacuum cleaner? Find out below.

When to change the dust collector filter

The dust filter of the vacuum cleaner, and the dust extraction system should be replaced when there are signs of overload or corrosion. Through the following signs:

– Corrosion of the dust filter will show loose folds, and visible dust particles accumulated on the filter. The structure of the filter appears as holes, tears, or signs that are no longer the same. Looks like it’s time for a new filter.

– Poor filtration efficiency: Measure excess filter pressure, if there is an excessive difference in pressure between the dirty and clean air inlet of the filter, the clean air inlet pressure decreases. there is a possibility that the filtration is not effective, the air is no longer flowing freely through the filter media. This leads to clogged filters and inefficient operation.

– Dirty exhaust gas: The exhaust gas stream after the filtration process still has a large amount of dirt. Because the filter is worn or has holes, the filter is not clean. Instead of dust particles being trapped, they followed the gas stream out.

So if you notice the above signs, replace the new filter for the vacuum cleaner immediately.

How often should the vacuum cleaner filter be changed?

Filter replacement is an important part of any dust collection system. However, depending on the type of dust collection system, the filter replacement time is different. Because filter life varies depending on your system. Dust filters have a lifespan that lasts from 1 to several years and some types need to be changed every 3 months.

Factors affecting the time to change the filter for a vacuum cleaner

– Volume and nature of dust collecting: As more dust is collected, the filter loads faster. The filter life is also reduced. For example, collecting wet dirt, wet dust particles, and greasy … can quickly clog the filter. And need earlier filter replacement time than dry dust. Or if collecting dust from welding fumes, high-temperature dust… will need to change the filter more often than factories that collect low-volume dust, dust from manual processes.

– Filter media type: The quality of filter media also affects their lifespan. You can refer to the information about the filter media that you are using.

– System air-to-fabric ratio: The higher the particle load, the more filter media is required (low air-to-fabric ratio). If the air-to-fabric ratio is too high, the filter should be changed frequently.

– Excess dust removal device: Filter pulse systems use compressed air to remove excess dust on the filter, preventing dust from being entrained in the filter media. Take care of the filter pulse system regularly to maximize filter life.

Thus, it is easy to recognize when it is time to change the filter for the vacuum cleaner. Answering the question of how often to change the dust filter, you should learn about the type of dust and dust load. As well as refer to the information from the filter supply to know more.
