Vacuum cleaners will pick up more dust and work more effectively if their filters are cleaned for 10 minutes once a month. A clogged filter weakens suction and can overheat the motor, leaving floors dusty no matter how often the appliance is used.
Why filter cleaning matters
Homes tend to become dustier in October as colder weather leads to closed windows and heating being turned on. This causes dust to build up quickly, making vacuum filters more likely to become blocked at this time of year.
Vacuum filters usually only need clearing once a month. If left uncleaned, accumulated dust can cause the filter to overheat, wearing it out and shortening the vacuum's lifespan. Regular cleaning can save money in the long run.
Signs your filter needs cleaning
Leslie Murray from vacuum manufacturer My Heny said it “only takes a few minutes” to clean a filter. Murray added: “More loose dust escaping, louder motor sounds, or weaker suction can all indicate that your filter needs to be cleaned. They’re often caused by dirt buildups blocking airflow. Thoroughly cleaning the filters should restore your vacuum’s performance to its original state.”
How to clean a vacuum filter
To begin, unplug the vacuum and ensure it is completely switched off before disassembling the filter. After carefully removing it, gently tap it over a bin or use a soft cloth to remove loose dust.
The filter looks like a small cover near the container. On cordless vacuums it is usually inside the container, while on older models it is typically on top of or underneath it.
Running the filter under lukewarm water can help remove smaller dust particles, but check the vacuum instructions or look online first, as some filters are not washable. If the filter can be exposed to water, leave it somewhere safe for at least 24 hours after washing to ensure it is completely dry before putting it back.
Cleaning a filter is easy and should take 10 minutes at most, but it is one of the most effective ways to ensure the vacuum works better and makes cleaning a lot easier.
