UNS Blitz Stainless Steel Filter
A tiny canister filter with a brushed stainless steel body and matching steel pipes. It is made for nano tanks where a plastic canister would look out of place, and it runs quietly on low wattage.

Will it suit my tank?
litres
Best for
Nano and desktop tanks where the filter sits on show next to the aquarium.
Worth knowing
Media capacity is small, especially on the 6 oz, so expect to clean it more often than a bigger canister.
What stands out
- Two sizes: 6 oz (tanks up to about 10 L) and 32 oz (up to about 45 L)
- Stainless steel canister with matching inflow and outflow pipes
- 6 oz runs from USB; 32 oz uses a 12 V supply
- Only 2 W and 5 W

Frequently asked questions
Quick answers about the UNS Blitz Stainless Steel Filter, drawn from its specs.
What size tank is the UNS Blitz Stainless Steel Filter good for?
