I've had my Clear Vue for about 12 years. About 6 years ago while contemplating purchasing replacement filters, I called Mr. Wynn of Wynn Environmental, maker of the filters used in the CV, to ask him how to clean the filters. He gave me an idea I've used over the years. It requires two leaf blowers. I stick one leaf blower in the end of the filter and turn it on. Then I used the other leaf blower to blow the dust from the outside in (very important according to Mr. Wynn). As the dust is forced back inside the filter, the other leaf blower carries it away. My collector uses two stacked filters, I just leave them attached to each other for the cleaning operation. I also use my hand to tap the filters as I clean, this also removes considerable dust. Warning: this process generates an EXTREME amount of dust out the end of the filter. Be sure it's cleaned outside on a windy day, and be sure the wind is blowing in a favorable direction.
Mr. Wynn explained that the filters could be damaged by air pressure from a compressor hose, especially if the nozzle is placed too close to the filter while cleaning it. The pressure is far less from a leaf blower and non-damaging to the filters. That said, I have replaced my filters as there comes a time when cleaning is no longer particularly effective.
