Brand Names & Products We Suggest

Swimming Pool Filters

Pool Filters

The pool filter is used in conjunction with your pump to keep your pool clear of oils, debris, dirt, and algae spores. Together, this is called the filtration system.

You’ll have several filter choices for your pool, including sand, cartridge, or diatomaceous earth (DE.) Each type of filter has its own unique pros and cons that make them less or more ideal for certain types of pools. Generally speaking, cartridges offer a finer filter medium than sand, but they’re not really designed to accommodate the needs of a larger pool and have to be replaced at least every three years. Sand filters typically have the lowest overall cost considering they last up to seven years, but they’re also a lot of work in that they require frequent backwashing that can easily alter your pool’s chemistry.

For most in-ground pools, we recommend a DE filter for the best overall value and cleanliness. These use a white powder made from crumbled sedimentary rock. It filters much like sand, but they provide a finer and more effective medium. While DE filters still require backwashing, they offer a superior filtration that can cut debris down to just five microns verses sand’s 20 microns and a cartridge’s 10 microns.

Swimming Pool Pumps

Pool Pumps

Just as an engine is the heart of a vehicle, your pump is the lungs of your pool. It’s the key component of the filtration system that keeps your pool’s water clean. It’s crucial that your pump is the right size for your pool and in good working order. Otherwise, your pool can quickly fill with debris and turn a slimy, green mess.

For most standard pools, we recommend the Jandy FloPro pump for its combination of stellar design and price point. It’s a single speed pump with enough power to accommodate most any sized pool. Yet, it’s very easy to maintain and service.

One feature pool owners particularly enjoy is the clear plastic trap lid, which makes it easy to identify when the trap basket needs to be cleaned. The intake and discharge have union plumbing, which makes maintenance a snap. As one of the quietest pumps on the market, you’ll likely not even hear it running as you swim. Affordable innovation makes the Jandy FloPro pump a real standout and our top recommendation in this category.

Swimming Pool Heaters

Pool Heaters

If you’d like to heat your pool for comfort and use throughout cooler seasons, you’ll want to look at pool heaters. You’ll have two options: gas-fired heaters or heat pumps. Again, you’ll find pros and cons of both in regard to your needs and pool specifics.

Overall, heat pumps are the most affordable option for day-to-day use. Their heating ability is very limited, though. In geographical regions with colder Spring and Fall seasonal temperatures, you’ll likely find a heat pump all but ineffective. This is why we recommend most pool owners look at propane or natural gas-fired heaters as the most comprehensive and reliable heating source.

Our favorite pool heater is the dependable and simple design of the Raypak RP digital heater. Raypack is a division of Rheem that’s almost entirely focused on heaters, which is a testament in of itself to the quality of their heaters. Programming with the Raypack RP digital heater is straightforward with the digital display, and the display also makes troubleshooting problems and maintenance needs easier and quicker. It’s design can accommodate most any pool size through reasonably cooler temperatures.
