|The Type Of Filter My Vacuum Uses|
When emptying the dust bin on the vacuum cleaner I use a rubber scrub brush to clean out the dust and bird feathers from the filter. By tapping the filter briskly with the scrub brush more dust will come loose. I like the rubber brush as it doesn't rough up the surface of the filter, but it does grab all of the dirt.
Once a month I hose the filter clean (you can also use a mild dish soap) and let it dry thoroughly before putting it back in the vacuum cleaner. I have used the same filter for a couple of years without any loss of function. As long as the filter material remains in good condition is can be reused.
My rubber scrub brush is from the FlyLady and I really like it. It is also very good at getting hair and dirt off of upholstery. But, I am sure there are other rubber brushes out there.
In this case a little labor can save a great deal of money. Which can be said about many things about the house.
