Sand filters
- HaywardHayward ProSeries Sand FilterHayward's above-ground sand filter — which size your pump needs, how much sand the 18-inch takes, when to backwash, and what the W3 prefix does to the warranty.
- HaywardHayward ProSeries Side-Mount Sand FilterHayward's side-mount ProSeries sand filter, S244S and S310S: the valve each one takes, why it backwashes at 6 to 8 psi, and the parts that changed in 2024.
- JandyJandy SFSM Sand FilterJandy's side-mount sand filter in four sizes: how much sand each takes, the backwash valve it can't run without, and a weight limit its own sand table breaks.
- JandyJandy SFTM Sand FilterJandy's top-mount sand filter in its two sizes: how much sand each takes, the pressure that means backwash, and why one bought online has no Jandy warranty.
- PentairPentair Sand Dollar Sand FilterPentair's Sand Dollar top mount filters, SD 35 to SD 80 and the ClearPro: area, flow and sand by size, when to backwash, and three parts lists that disagree.
- PentairPentair Tagelus Sand FilterPentair's Tagelus top mount sand filter, TA 40D to TA 100D: flow and freeboard by size, the valve clamp, and why its sand weights don't agree.
- PentairPentair Triton II Sand FilterPentair's Triton II side mount sand filter in three sizes: why the TR 100 barely out-flows the TR 60, the valve you buy separately, and sand or gravel by size.
Cartridge filters
- HaywardHayward StarClear Plus Cartridge FilterHayward's older one-cartridge filter: the 2-inch models that replaced the C900 and C1200, why the 175 isn't faster, and the knob that can end it.
- HaywardHayward SwimClearThe four-cartridge Hayward filter, which model fits your pump, the cartridge number for each one, and why the C7030 takes eight elements rather than four.
- HaywardHayward SwimClear Single-Element Cartridge FilterHayward's one-cartridge SwimClear in three sizes: the C275S that replaced the C200S, why its 200 GPM rating runs past Hayward's flow limit, and clearances.
- JandyJandy CS Cartridge FilterJandy's single-cartridge filter in four sizes: why three of them share a 125 GPM limit, when to clean it, and the breather tube that matters for safety.
- JandyJandy CV and CLJandy's four-cartridge filters: how the CV and CL differ, the clamp that closes to a gap rather than a torque, and why no store link appears here.
- PentairPentair Clean & Clear Cartridge FilterPentair's single-cartridge filter in five sizes: the flow rate Pentair actually recommends, the lock ring and restart steps, and the headroom each size needs.
- PentairPentair Clean & Clear PlusThe four-cartridge Pentair filter, which size actually fits your pump, the cartridge numbers for each model, and the clamp Pentair changed in August 2025.
D.E. filters
- HaywardHayward Perflex D.E. FilterHayward's Perflex bump D.E. filter, EC40AC to EC75A: how much D.E. each size takes, when to bump and when to clean, and what lets D.E. into the pool.
- HaywardHayward ProGridHayward's vertical grid D.E. filter: how much powder each size takes, the two flow ratings, the clamp torque in inch-pounds, and why D.E. gets back in the pool.
- JandyJandy DEV D.E. FilterJandy's vertical grid D.E. filter: the powder each size takes, two maximum flows depending which document you read, and the clamp gap that decides if it's safe.
- PentairPentair FNS PlusPentair's D.E. filter — how much powder each size takes, the two flow ratings Pentair publishes, when to backwash, and the clamp that changed in August 2025.
- PentairPentair Quad D.E.Pentair's four-cartridge D.E. filter: why the Quad 100 flows no more than the 80, the clamp that changed in 2025, and what puts powder back in the pool.
Compare filters side by side
Pick two or three models. Every figure is the one on its product page, which links the manufacturer’s documents. Where a page gives a figure under its own label, such as design flow rather than maximum flow, that label is shown with it, and a figure the page gives for a whole range of models says so. Not sure what size you need? The sizing calculator works it out from your pool and pipes.
Pick two filters to see them side by side. The table fills in as you choose.
