Key Takeaways

  • Intex Type A three-pack: The 29003E cartridge set is the #1 bestseller in its slot and the cheapest way to stop nursing a gray, crusted filter through August.
  • Know your letter before you buy: Intex pumps take Type A or Type B, and Coleman SaluSpa units take Type VI. The letter is printed on the old cartridge.
  • Pool robots are the deepest cuts: The OUCAXIA Y10 and the zebary cordless vacuum are both at half off, which is where I start paying attention to this category.
  • Discount range this week: 38% to 56%, with the filter parts leading. Prices verified July 12, 2026.

There is a very specific July moment where you pull the cartridge out of the pool pump, hold it up, and realize it has gone from white to the color of weak coffee. You rinse it with the hose. It looks slightly less bad. You put it back in anyway, because the pool is full of kids and the water is fine, probably. That cartridge should have been replaced three weeks ago, and the reason your pump sounds like it is straining is that it is.

So that’s where the Berry Basket landed this week. Above ground pool filter cartridge replacement is not glamorous, but it is the single cheapest thing you can do for water clarity in the back half of summer, and the deals reflect a category that sellers know people are searching for right now. The Intex Type A three-pack is sitting at the top of its bestseller list, the Coleman SaluSpa Type VI two-pack is down by half, and there’s an Intex Type B fittings adapter in here for the people running a bigger pump than the hoses were built for.

Beyond the filter housing, Prime Day pricing has gotten aggressive on cordless pool robots, which is a category I’ve been tracking all season and finally see landing at prices that make sense. Also in here: a floating thermometer, a very large Intex pool for anyone going all in, and two trimmer spools, because a July lawn does not stop growing just because you’re in the water. Browse all deals if you want the wider garden sweep.

Which above ground pool filter cartridge replacement do you need?

Check the letter stamped on the cartridge you already have. Intex pumps use Type A or Type B, Coleman SaluSpa inflatable spas use Type VI, and the sizes are not interchangeable no matter how close they look on a shelf.

Rule of thumb on frequency: rinse weekly, replace roughly every two weeks in heavy swim season, sooner if the water has gone cloudy and the chemistry checks out fine. Buying a multipack is the whole game here, because single cartridges cost nearly as much as a three-pack on sale.

Intex Type A Filter Cartridge

This is the one most above ground pool owners are looking for. Type A fits the standard Intex filter pumps, the Dacron paper media rinses out easily between swaps, and a three-pack covers most of a season if you’re changing them on a sensible schedule. It’s the #1 bestseller in its category, and at 56% off it’s the deepest cut on this list.

  • Fits standard Intex filter pumps
  • Dacron paper media, easy to rinse
  • Three pack

Coleman SaluSpa Type VI Cartridge

If your water is a Coleman SaluSpa inflatable hot tub rather than a pool, this is your cartridge. Type VI, two per pack, and worth buying in quantity because spa filters clog faster than pool filters thanks to body oils and sunscreen. Cheap insurance against a pump that starts running loud.

  • Type VI for SaluSpa filter pumps
  • Two pack
  • Trusted brand replacement part

Intex Type B Fittings Adapter

Not a cartridge, an adapter. This is the Intex Type B clamp-on fittings pair that lets a larger filter system connect to pool ports it wasn’t originally sized for, which is the fix when you’ve upgraded the pump but kept the pool. Small part, annoying problem to have without it.

  • Clamp-on fittings adapter pair
  • Connects large filter systems
  • Gray, Intex Type B

Are cordless pool robots worth it for an above ground pool?

At half off, yes, with one condition: they handle floor debris, not walls. For a flat-bottom above ground pool that collects leaves and grit, a cordless robot saves you the manual vacuum hose ritual entirely. For a deep inground pool with a lot of waterline scum, you want a corded unit with wall climbing, and those cost considerably more.

Both of the cleaners below are at 53% and 50% off, which lines up with the pricing pattern I flagged in the cordless robotic pool cleaner roundup earlier this season. Runtime is the spec to check, not suction claims.

OUCAXIA Y10 Pool Cleaner

The Y10 is currently ranked #6 in its category and is the value pick between the two robots here. 150 minutes of runtime, dual suction, self-parking so it doesn’t die in the middle of the pool, and it’s rated for above ground and flat inground pools up to 1,300 sq ft. That coverage number covers most backyard above ground setups with room to spare.

  • 150 minute runtime, cordless
  • Dual suction, self-parking
  • Covers up to 1,300 sq ft

zebary Cordless Pool Vacuum

The zebary robot goes bigger on both fronts: 200 minutes of runtime and coverage up to 2,500 sq ft, so it’s the one for a larger pool or a pool that gets a lot of leaf fall. Same cordless, self-parking setup. You’re paying more for capacity, and if your pool is small you don’t need it.

  • 200 minute runtime
  • Coverage up to 2,500 sq ft
  • Above ground and inground

What else keeps the water in decent shape?

Water temperature and shade do more for a pool’s usability than most accessories. A thermometer tells you whether the water is actually as cold as the kids are claiming, and a shaded corner is what keeps small children in the yard instead of inside.

Sainlogic Floating Pool Thermometer

A floating wireless thermometer with an IP68 waterproof rating, which is the spec that matters when the thing lives in chlorinated water all summer. It reads to the display so you’re not squinting at a floating duck at dusk. Also works in a hot tub, pond, or cold plunge, which is a nice range for a small purchase.

  • Wireless with remote display
  • IP68 waterproof
  • Works in pools, hot tubs, ponds

Intex Ultra XTR Pool Set

Here’s the big swing. The Ultra XTR is a 26 foot round steel frame pool with a 2,800 GPH sand filter pump, ladder, cover, and ground cloth included, and it’s down 41% as a Prime Day deal. Worth noting for search purposes: a sand filter pump means no cartridges to replace, just sand backwashing, which is a real long term cost difference. Only sensible if you have the yard and the patience for the setup day.

  • 26 ft x 52 in steel frame pool
  • 2,800 GPH sand filter pump
  • Ladder, cover, and ground cloth included

Intex Sun Shade Kiddie Pool

A five foot inflatable kiddie pool with a canopy over it, rated for ages three and up. The canopy is the whole point in July, since a shadeless kiddie pool heats up to bathwater by noon and nobody wants to be in it. Ten gauge vinyl is thicker than the flimsy blow-up pools that puncture in a week.

  • 5 foot square inflatable pool
  • Canopy for shade
  • 10 gauge vinyl, ages 3+

One thing for the deck

Only one poolside pick made the cut this week, because the umbrella deals were mostly the same 40% off on interchangeable market umbrellas and I don’t need to show you four of them.

Christopher Knight Nataly Side Table

A 17.25 inch carved garden stool in lightweight concrete, which is the good version of this look. Real concrete garden stools are miserable to move and this one isn’t, but it still has enough weight to not skate around on a windy deck. Works as a side table next to a lounger or a plant stand once the pool comes down in fall. If you’re setting up the whole evening scene, the solar string light picks pair with it.

  • 17.25 inch carved garden stool
  • Lightweight concrete
  • Side table or plant stand

Which string trimmer spools are cheap right now?

Trimmer line is the consumable people forget to restock until the trimmer runs dry mid-edge. Both of these are trusted brand spools at 50% and 38% off, and both are sold and shipped by Amazon, which reduces the odds of a knockoff spool that doesn’t seat properly.

Match the line diameter to your trimmer, not to the price. The wrong gauge either won’t feed or will bog the motor. If you’re still shopping for the trimmer itself, our notes on cordless trimmers for small yards cover which battery platforms are worth committing to.

Greenworks 80V Trimmer Spool

The 0.080 inch replacement spool for Greenworks 80V front mount trimmers. If you’re on the 80V platform this is the correct part and there isn’t much to decide, other than buying it before you need it. Half off on a genuine spool is the right time.

  • 0.080 inch line
  • Fits 80V front mount trimmers
  • Genuine Greenworks part

BLACK+DECKER AF-100-3ZP Spool

The AF-100 is the single most common replacement spool in the yard tool world, fitting a long list of BLACK+DECKER trimmers. Thirty feet of 0.065 inch line, three spools to a pack. Buy the genuine one, because the third party AF-100 clones are the number one reason people think their auto-feed is broken.

  • 30 feet of 0.065 inch line
  • Three spools per pack
  • Fits most BLACK+DECKER trimmers

Frequently asked questions

How often should I replace an above ground pool filter cartridge?

Rinse it weekly and replace it roughly every two weeks during heavy swim season. If the pleats stay gray after a hose rinse, or the pump pressure stays high, the cartridge is done. Most people stretch them far longer than they should, which is why the water goes cloudy in August.

What size filter cartridge does my Intex pool pump take?

Intex pumps use either Type A or Type B, and the letter is printed directly on the cartridge you’re replacing. Type A is the smaller and by far the more common size for standard above ground Intex filter pumps. If you’ve lost the old one, check the model number on the pump housing before ordering.

Can I use a Coleman SaluSpa Type VI cartridge in an Intex pool?

No. Type VI is sized for SaluSpa inflatable spa pumps and won’t seat correctly in an Intex pool filter housing. A cartridge that doesn’t seat lets water bypass the filter entirely, so the pump runs and nothing gets cleaned.

Do cordless pool robots replace the filter cartridge?

They don’t. A robot picks up leaves and grit off the pool floor, but the pump and cartridge still handle the fine particulate and circulation. Think of the robot as a vacuum and the cartridge as the filter, and you still need both.

Is a sand filter pump cheaper than cartridges over time?

Usually yes, once you get past the higher up front cost. A sand filter like the 2,800 GPH pump on the Intex Ultra XTR set is backwashed rather than replaced, and the sand itself lasts years. Cartridge pumps are cheaper to buy and more expensive to keep running.

Discounts on this week’s garden pool selection ran from 38% to 56%, and the pattern is clean: the deepest cuts sat on the small replacement parts rather than the big hardware. The Intex Type A three-pack at 56% off and the Coleman Type VI two-pack at 52% off are the kind of markdowns you rarely see outside Prime Day week, because consumables normally hold their price all summer. Meanwhile the umbrella category was noisy and largely identical, four or five near-clone market umbrellas all sitting at 40% off, and I skipped most of them.

Honest take: this is a good week if you own a pool and a mediocre one if you don’t. The standout is the Intex Type A cartridge three-pack, not because it’s exciting but because it’s the highest return per dollar on this entire page, and it’s the part most people are running past its life. Second standout is the OUCAXIA Y10 at half off, which is the first time this season I’ve seen a cordless robot land at a price I’d call reasonable rather than aspirational. The Intex Ultra XTR pool set is a real discount on a real product, but a 26 foot pool is a project, not a purchase, and I’d want a level yard and a free weekend before I clicked. If your July spending is going toward the yard instead of the water, the Rain Bird sprinkler part markdowns and the pet safe mosquito repellents are better use of the money.

Looking ahead: cartridge pricing tends to hold through August and then fall off a cliff in September when nobody is swimming, so if you only need one more set to finish the season, waiting is a legitimate strategy. The robots are the opposite. Prime Day pricing on cordless cleaners will lift the week after and I don’t expect these numbers back until late fall clearance, when you’d be buying for next year. Filter first, robot if you’ve been circling one, and go rinse that cartridge.
