The Intex Krystal Clear cartridge filter pumps are produced for circulating and filtering the water of an Intex above ground storable swimming pool. It cannot be used for permanently installed above ground pools.
The Intex Krystal Clear cartridge filter pumps are available in different sizes with different pump flow rates. Our review considers the most popular pump size which has a pump flow rate of 1000 gallons per hour and a system flow rate of 750 GPH. Its model number is 28637EG, but it is also known by its component part number 637R.

- Cover seal
- Filter cartridge
- Hose seal x 2

The Intex 28637EG filter pump has 1-1/4-inch hoses. The Intex Krystal Clear cartridge filter pumps are shipped with all the hoses, clamps and connectors you need to attach it to the Intex above ground pool.
Which cartridge filter does it use?
Some owners say that it uses a size A or C cartridge filter. The Intex 637R filter pump manual mentions a filter cartridge with part number 29000. This is a type A filter. We saw an Intex type A filter cartridge with model number 29000E listed at Amazon.com. This is probably the the right filter cartridge for the Intex 1000 GPH filter pump.
Which pump for Intex Easy Set pools?
Look at the size (in feet) of the Easy Set above ground pool. We suspect this might be a very rough estimate of which GPH pool pump you need. However, let us see which pool pumps are included with the different Intex Easy Set pool sets.
- 8 feet by 30 inches pool set: includes the 330 GPH cartridge filter pump.
- 10 X 30: comes with the 530 gallon per hour filter pump.
- 12 X 30: includes the 530 GPH pump.
- 15 X 33: 530 gallon per hour filter pump is included.
- 18 X 48: shipped with the 1500 GPH cartridge filter pump.
So where does the 1000 GPH filter pump fit in? Well, we think it should fit in with the 10 to 12 feet Easy Set pools.
The 530 GPH filter pumps are probably best for pool sets under 10 feet. You might use the 1000 GPH for 10 to 12 feet pools. Use the 1500 GPH cartridge filter pumps for 15 feet pools. This is only our rough guide for Intex Easy Set pool and pump sizes.
Which pump for Intex metal frame pools?
The 12 feet by 30 inches metal frame pool set comes with the 530 GPH cartridge filter pump, which we think might be too small to effectively circulate the water. In our raw opinion, the 1000 GPH pump would circulate and filter the water better.
The 15 X 33 Intex metal frame pool also includes the 530 gallon per hour cartridge filter pump. We would recommend an upgrade to the 1500 GPH Intex pump for a fifteen feet above ground pool size.
The Intex 24 X 52 metal frame pool set uses the 2500 gallon per hour filter pump. This is the right pump for a 24 feet pool size.
When it comes to safety, it seems that the “EG” model pump comes with a GFCI plug. The older “E” model does not have this safety plug feature. The pump runs on 110-120V electrical current.
The cartridge filters can be removed and cleaned by spraying it with water. Clean the filter a few times each week, depending on the dirtiness of the pool water. This way you can use and clean the filters multiple times instead of replacing it every two weeks as the manufacturer suggests. You can save some money on filters. Nonetheless, the cartridge filter will eventually need replacement after cleaning it an unknown number of times.
The longevity of these Intex cartridge filter pumps are probably decreased due to the use of plastic parts. However, this is a cheap pump, so this is to be expected.
The Intex Krystal Clear cartridge filter pumps might last for a few years before something breaks. At an affordable price of less than 100 dollars, these Intex pumps are worth the investment.
You might also consider using an Intex Krystal Clear sand filter pump (read review). Sand filter pumps are more efficient and the sand only needs replacement after a few years of use. The sand is cleaned by backwashing and rinsing the sand filter with the pump valve positions.
