Best aquarium filters: what to look for before you buy
A buying checklist for aquarium filters, with what eBay buyers actually paid. We do not stock this type, so the advice is not steering you to our own product.
Size the filter to the tank volume with room to spare, then choose the type by how much you want to maintain it. Flow you can adjust matters more than the biggest number on the box.

What to look for: 6 checks
These are the points that separate a good aquarium filters from a poor one, in the order they usually matter.
- Rated tank volumepick a filter rated for a tank larger than yours, since the rating assumes a lightly stocked tank. A 100 litre tank wants a filter rated for 150 litres or more.
- Flow rate and adjustmentturnover of about four to six tank volumes per hour is a common target. A dial to turn the flow down helps with small or slow-swimming residents.
- Typehang-on-back units are easy to service, internal filters suit small tanks, canister filters handle large tanks and hold more media but take longer to open up and clean.
- Media spacea filter with room for sponge, ceramic rings and carbon in separate trays lets you rinse one layer without wiping out the rest.
- Intake guarda fine sponge or slotted cover on the intake stops small fry and shrimp being pulled in.
- Cartridge supplya filter that only takes sealed cartridges means buying them forever. Look for one that accepts loose media you can rinse and reuse.
The mistake to avoid
- Many hang-on units list a flow figure measured with the cartridge removed. Once media is packed in, real flow drops, so size up one step.

On 2026-11-01, eBay buyers paid a median of $29.99 for aquarium filters (search "aquarium filter"), across 6,400 sold listings. That is real money changing hands on eBay, which makes it a useful anchor when you compare asking prices elsewhere.
How to read it: the count is the sold-result total eBay shows for a search of sold and completed listings, and the median is from the first page of prices (about 60 listings, new and used mixed). It is not an Amazon price, it ignores shipping and condition, and it does not say what a given product is worth. A different spec will sit well above or below it.

Questions
Can I run a filter that is too big?
Yes, as long as the flow can be turned down or baffled. Oversized filtration is easier to live with than undersized.
How often should I rinse the media?
Rinse sponge in old tank water, never under the tap, and only when flow visibly slows. Rinsing everything at once wipes out the layer that does the biological work.
