Frequently Asked Questions
Which Dahle shredders does the 20710 filter fit?
All DAHLE CleanTEC models: 41334, 41434 and 41534 in the high-security range, the oil-free 51314, 51414, 51464, 51514 and 51564, and the automatic-oiler 51322, 51422, 51472, 51522 and 51572. Dahle lists the 20710 as the single replacement air filter across the CleanTEC family, so you do not need to match a sub-variant to your model. It will not fit PaperSAFE, ShredMATIC, PowerTEC or the non-CleanTEC 4-series machines, none of which have a filter housing.
How often should the filter be replaced?
Dahle does not publish a service interval for this part, so we cannot quote one. In practice it is a condition-based change: inspect the cartridge face and replace it when it is visibly loaded with dust or when the machine starts throwing visible particulate again. A shredder run near-continuously will consume filters far faster than one used for a few minutes a day, so a single calendar figure would be misleading.
Can the filter be vacuumed out and reused?
No. Dahle sells the 20710 as a replacement cartridge, not a washable or serviceable element, and there is no published cleaning procedure for it. Vacuuming the face may dislodge surface debris but will not restore the media, and aggressive cleaning can damage it. Replace it rather than attempt to recondition it.
Does a new filter come with the shredder?
Yes, a CleanTEC machine ships with its filter already installed. The 20710 is a consumable ordered separately once that original cartridge is loaded. If you are buying a new CleanTEC you do not need one on day one, though most facilities buy a spare at the same time so the change-out is not delayed by a purchase order.
Is 98% dust removal an independently certified figure?
It is Dahle's own stated performance for the CleanTEC filtration system, quoted as trapping up to 98% of fine shredding dust. We have not seen an independent third-party test report behind it, and there is no HEPA class or ISO 16890 rating published for this cartridge. Treat it as a manufacturer specification rather than a certified laboratory result.
