The Hayward Perflex pool filter on a blue patterned background

The Spruce

To determine what pool filter is best for you, consider the volume of water in your pool.

This filter provides top-of-the-line filtration, removing particles down to two microns.

Hayward makes no specific claims regarding pathogens, but many bacteria fall into that size range.

Of course, it also filters larger debris just as efficiently.

We like how easy this filter is to maintain, especially considering how well it filters.

However, its still a low-maintenance option compared to cartridge models that require cleaning every few weeks.

We like this all-in-one filtration solution because it has everything you need except the sand.

This filtration system works with most small to medium-sized pools, with a maximum coverage of 4,800 gallons.

Thats about the same as a 14-foot round pool with a depth of 4 feet.

However, it filters very well, and the filters are easy to clean.

This is a pump and filter combination, which makes it a much better deal.

We like the visible indicator that shows when the filter needs to be serviced and is easy to access.

The high-quality dacron filters can be washed off several times before they need to be replaced.

This filtration system uses sand in a reinforced, molded tank for efficient filtration and backwashing.

ThePentair EC-342001 SuperFlo VSis a very efficient option that works with many of our filter recommendations.

We like how easy this filter’s design makes it to jump into the diatomaceous grids for service.

If your pool is even bigger than that,Hayward makes one larger optionfor pools up to 86,400 gallons.

Youll also need to supply your own pump since this is just the filter.

It offers excellent filtration and creates chlorine from salt in one convenient package.

We love how easy this system is to set up and maintain.

The sand filter included with this system has a lower flow rate.

When looking at the capacity of a pool filter, the manufacturer may provide a handful of different numbers.

You may see a square footage rating for diatomaceous filters and some cartridge filters.

Then, select a pump with a flow rate that has an appropriate flow rate for that filter.
