The Swirl Universal Air Filters are customizable and can therefore be used in almost any vacuum cleaner with an exhaust filter. The Swirl Universal Air Filter is responsible for cleaning the vacuum cleaner's exhaust air. This air may contain particles that have been worn off due to the rotation of the motor. This is a completely normal condition and nothing unusual. The Swirl Universal Air Filter thus ensures healthier cleanliness in the room. It is suitable for all vacuum cleaners for which there is no specific microfilter available and can be individually trimmed.
