air filter Haier HVC500

air filter for the Haier HVC500 vacuum cleaner.factory filter did not last long.decided to look for what to buy ,the price was not small and it was decided to do it yourself.as a filter paper was found air filter fine from the truck equipment.the height of the corner of the crest 10-11 mm.on the laser cutter cut circles and a strip long on the inner circumference of the filter and glued it all together.after drying this paper filter was glued into a plastic housing on the car sealant.I really liked the test results.
