Intex Hot Tub Pump Parts and Filters Explained

Intex is best known for inflatable hot tubs and above ground pools that you can set up yourself in a weekend, and nearly all of them rely on a small pump and a paper filter cartridge to keep water moving and clean. When the water turns cloudy or the pump starts buzzing, most owners do not need a new tub. They need the right filter or the right replacement part, and the hardest part is matching letters and model numbers.
The six products below cover that whole journey: a replacement impeller from another company made for one Intex PureSpa pump, a complete SimpleSpa tub, two packs of Type S1 spa filters, and two pool products (a sand filter pump and Type H cartridges) that are often confused with spa parts but are made for above ground pools.

for Intex Pump Model SSP-H-10-2 SSPH102
Best for: PureSpa owners with a noisy or seized pump
Pros
- Stainless steel shaft
- Ceramic thrust washers included
- Two rubber caps and bushings
Cons
- Third-party part, not made by Intex
- Fits one pump model only
This replacement part, sold as for Intex Pump Model SSP-H-10-2 SSPH102, is made by a company called ZCLYHT, not by Intex. It is an impeller, sometimes called a rotor: the small magnetic spinning piece inside the pump that pushes water through the heater and filter. When an impeller wears out or gets clogged with debris, a spa pump often hums without moving water or becomes noisy.
The listing says it includes one impeller with a stainless steel shaft, two rubber caps, bushings and ceramic thrust washers (the small discs that let the shaft spin smoothly). It is meant for the Intex PureSpa pump SSP-H-10-2, also written SSPH102 or 403M. It weighs 2.24 ounces and measures 3.15 by 2 by 1.69 inches. The listing calls it “OEM replacement,” but since it comes from a third-party seller, treat that as meaning it is designed to match the original rather than being an Intex-made part.
This suits a handy PureSpa owner who has confirmed the pump model number on the unit’s label. If your Intex spa pump has a different model number, this part is not listed for it, so check before ordering.
INTEX SimpleSpa 4 Person Inflatable Hot for Complete Beginners
Intex
INTEX SimpleSpa 4 Person Inflatable Hot Tub, Portable Spa with 100 Jets
Price and specifications are read from the Amazon product page and can change.
INTEX SimpleSpa 4 Person Inflatable Hot
Best for: First-time spa owners wanting a complete tub
Pros
- 100 bubble jets, seats four
- Insulated cover and ground cloth
- Hard water treatment built in
- Two S1 filters included
Cons
- Bubble massage, not water jets
- Heater details not listed
The INTEX SimpleSpa 4 Person Inflatable Hot tub is the only complete spa in this list. It holds 210 gallons, seats four, measures 77 by 77 by 28 inches and has 100 jets. The listing describes heated air bubble technology, which means warm air bubbles rise through the water for massage, rather than the powered water jets found on some tubs.
It comes with an insulated spa cover and insulated ground cloth to hold heat, a horizontal beam and mesh construction to resist punctures, and a built-in hard water treatment system that reduces mineral buildup. Filter changes happen at an integrated control box, and it includes two Type S1 filter cartridges, which is a useful clue: this Intex SimpleSpa uses the same S1 filters as the packs below. The listing does not specify heating speed, maximum temperature or pump wattage.
This tub suits a first-time buyer or a gift for a family wanting a simple backyard spa. For bigger groups, see our guide to the Intex 6 person hot tub options.
Intex 29011E PureSpa Type S1 Heavy for Stocking Up on Filters
Intex
Intex 29011E PureSpa Type S1 Heavy Duty Easy Set Dacron Paper Hot Tub Spa Filter Replacement Cartridge for Various PureSpa Models, 6 Pack
Price and specifications are read from the Amazon product page and can change.
Intex 29011E PureSpa Type S1 Heavy
Best for: PureSpa owners stocking up on S1 filters
Pros
- Six-pack of S1 cartridges
- Heavy-duty Dacron paper
- Genuine Intex part
Cons
- Needs monthly replacement
- No applicable warranty
The Intex 29011E PureSpa Type S1 Heavy duty pack contains six Type S1 cartridges. A filter cartridge is a pleated paper cylinder that traps dirt, hair and debris as the pump circulates water. These are made from heavy-duty Dacron paper, a durable polyester material that can be rinsed and reused for a while.
Intex recommends cleaning cartridges every week and replacing them once a month or sooner. The listing describes them as for various PureSpa models and the PureSpa Jet Massage, and gives a size of 4.25 by 4.25 by 2.75 inches for the pack. It does not name individual PureSpa model numbers, and there is no applicable warranty.
A six-pack suits owners who use the tub regularly and want half a year of monthly swaps on hand. If you want the model numbers spelled out, the next listing names them.
INTEX Type S1 Spa Filter Cartridge for Matching Your PureSpa Model
Intex
INTEX Type S1 Spa Filter Cartridge for PureSpa Inflatable Hot Tubs, 3-Pack
Price and specifications are read from the Amazon product page and can change.
INTEX Type S1 Spa Filter Cartridge
Best for: Owners of listed PureSpa model numbers
Pros
- Lists compatible PureSpa models
- Washable Dacron paper
- 25-inch diameter stated
Cons
- Title says 3-pack, text says 6
- No applicable warranty
The INTEX Type S1 Spa Filter Cartridge listing is the most specific about compatibility. It says it works with all Intex PureSpa models, naming 28403E, 28407E, 28443E, 28453E, 28421E, 28423E and 28413E. The cartridges are made of the same easy-to-clean Dacron paper, measure 4.25 inches across and come with the same weekly clean, monthly replace advice.
There is a clear mismatch in this listing. The title calls it a 3-pack, but the features and specs say six cartridges are included. Check the pack count on the product page before you buy, especially if you are planning months ahead. Like the other filter pack, there is no applicable warranty.
Choose this one if your tub’s model number is on that list and you want written confirmation it fits. Either S1 pack does the same job; the 29011E is simpler if you just need six.
INTEX Krystal Clear 925 GPH Sand for Above Ground Pools Only
Best for: Above ground pools, not hot tubs
Pros
- 6-function valve
- 24-hour timer, 2-12 hour cycles
- Sand lasts up to 5 years
- 2-year limited warranty
Cons
- Pool pump, not for spas
- Needs regular backwashing
The INTEX Krystal Clear 925 GPH Sand filter pump (model 26641EG) is a pool pump, not a hot tub pump. We include it because many people search for an Intex sand filter pump while shopping for spa parts. It is listed for above ground pools from 232 to 4,440 gallons.
A sand filter pushes water through a tank of sand that traps dirt, and you clean it by “backwashing,” which reverses the flow to flush debris out. Its 6-function valve lets you filter, backwash, rinse, re-circulate, drain and close. The listing names a built-in 24-hour timer with 2 to 12 hour cycles, a flow rate of 925 gallons per hour (550 in-pool), an 8-inch tank holding 14.3 pounds of sand, HydroAeration for better circulation, and sand that can last up to 5 years with regular backwashing. It weighs 16 pounds and has a 2-year limited warranty.
Buy this only if you also own an above ground pool. It will not replace the built-in pump of an inflatable spa. Our overview of every Intex hot tub explains what each spa’s own pump does.
INTEX Type H Pool Filter Cartridge for Small Pool Pumps
Best for: Owners of Intex 330 GPH cartridge pumps
Pros
- Six cartridges per pack
- Easy-to-clean Dacron
- Lists compatible pumps and pools
Cons
- Pool filter, not for spas
- Replace every two weeks
The INTEX Type H Pool Filter Cartridge six-pack is another pool product. Type H cartridges fit Intex Krystal Clear cartridge filter pumps rated at 330 gallons per hour, with models 28601 and 28602 named in the description, used on pools such as the 28125EH, 28111EH, 28121EH and 28201EH.
They are made of Dacron paper and Intex recommends replacing them every two weeks, more often than the monthly advice for spa filters. The listing mentions HydroAeration Technology when used with Intex filtration systems.
This suits a small above ground pool owner with a 330 GPH pump. Type H is not interchangeable with the S1 filters used in PureSpa and SimpleSpa tubs, so do not order it for a hot tub.
How to Choose the Right Intex Hot Tub Pump Part
Start with the label. Every Intex spa and pump has a model number printed on it. Write it down before shopping; it answers the question of which Intex part you need faster than any photo.
Filters by letter. PureSpa and SimpleSpa tubs in this list use Type S1 cartridges. Type H cartridges belong to small pool pumps. The letters are not interchangeable.
Impeller or whole pump. If your spa pump hums but water does not move, a worn or blocked impeller is a common cause. The ZCLYHT impeller fits only the SSP-H-10-2 pump and is a third-party part.
Spa or pool. The Krystal Clear sand filter pump and Type H cartridges are pool equipment. For an inflatable spa, stick with S1 filters and parts made for your spa pump. Our Intex inflatable hot tub guide lists tubs alongside their filter types.
FAQ
What filter does the Intex SimpleSpa use?
The SimpleSpa listing says it includes two Type S1 filter cartridges, so replacement S1 packs like the 29011E suit it.
How often should I change an Intex S1 filter?
Intex recommends cleaning S1 cartridges weekly and replacing them once a month or sooner.
Is the SSP-H-10-2 impeller made by Intex?
No. It is sold by ZCLYHT as a replacement designed for the Intex PureSpa pump SSP-H-10-2 (SSPH102, 403M).
Can I use the Intex sand filter pump on my hot tub?
No. The Krystal Clear 925 GPH sand filter pump is listed for above ground pools from 232 to 4,440 gallons, not spas.
Is the Intex Type S1 pack a 3-pack or a 6-pack?
The listing conflicts: its title says 3-pack while the details say six cartridges. Confirm on the product page before ordering.
What is the difference between Type S1 and Type H filters?
Type S1 fits Intex PureSpa and SimpleSpa hot tubs. Type H fits 330 GPH Krystal Clear pool cartridge pumps and should be replaced every two weeks.
