The Material that extraction canopies is made from is very important. Good extraction canopies should only use 405 to 430 grade stainless steel. The reason for this is that cheaper stainless steel stains easier and discolours. This also means cleaning becomes difficult and the extraction canopies will deteriorate faster than normal.
Good extraction canopies should have drain taps on the bottom edge; so that the excess oil that can get trapped in the filters can drain away properly and does not just build up within the bottom of extraction canopies. Extraction canopies should feel solid, especially around the filter banks with drain holes at the bottom of the filter bank.

As most filters are aluminium or stainless steel you can easily remove and clean with warm soapy water. Cleaning and maintenance of extraction canopies and extraction systems is vital.
