As a pool owner or manager, keeping your pool sparkly clean is important for the hygiene and safety of everyone that will be swimming in it. Swimming pool filters are an important part of your pool maintenance gear, and separate impurities like oil, dust, debris, and algae from the water as it is being pumped into the pool. The ideal swimming pool filter should be well sized to handle the flow rate of your pump, should be fine enough to handle very tiny impurities, and should be easy to replace.

Swimming Pool Filter Buying Guide

Swimming pool filters ensure the water coming into your pool is clean and free of impurities that may otherwise discolor the pool and be unhealthy to you. They are the first stage in pool sanitization before a more thorough microscopic-level sanitization is done with chlorination and algaecides.

Our buying guide reviews the best swimming pool filters on the market based on their specified features and customer feedback to give you the best options to choose from. We then take it a step further and guide you through your purchase as we outline the factors you should consider before you commit your money to a product.

Pool Filter Type

Pool filters generally come in three major types – sand filters, Diatomaceous Earth filters, and cartridge filters. Cartridge filters are generally the most common types of filters in home-size pools and are very easy to use. The filtering cartridge is often replaced after a week or two of use and they are very affordable. Sand filters are generally used for finer cleaning and use sand to sieve out impurities. They are cheap, reusable, but are the least effective in filtering. Diatomaceous Earth filters are the most top-rated filters and are the most expensive of the bunch. They also filter out water to the highest degree and are highly durable.

Pump and Pool Size (Flow rate)

Choosing your swimming pool filter will depend directly on the size of your pool, and consequently the size of the pump. The larger the pool, the larger the pump for faster filling, and thus the larger the swimming pool filter should. In general, it should large enough to handle the flow rate from the pump without lagging behind and causing pressure to build in the pre-filtration stage.

Filtering Medium Fineness

Hoe efficiently you want the filter to separate solid particles is another consideration to make. As stated above, sand filters filter out particles to about 20 microns, cartridge filters up to 10 microns, while DE filters can filter particles as small as 5 microns in size.

Easy Maintenance

The ease of maintenance is another important factor to consider. If you want the most hands-free operation, then cartridge filters are the way to go and will just need you to replace the cartridges once dirty. Sand and DE filters, on the other hand, will require you to often backwash them before they can be reused but save you the cost of having to buy any extra filtering media like cartridge filters.
