Pool filters come with a price range of $250 to $2,000, and this guide aims to assist you in finding the perfect match. Achieving a crystal-clear blue pool requires effort, and proper maintenance includes investing in key equipment. Among these, your pool filter stands out as a crucial element, ensuring contaminants are kept at bay from your water.

Pool Type

Understanding the selection process for the right pool filter can initially seem overwhelming due to the abundance of choices. However, breaking down the information will provide a clearer picture of what you can anticipate.

-Above Ground Pool

Above-ground pool filters range in price from $250 to $1,100. Due to the generally simpler plumbing systems and smaller size of above-ground pools compared to inground pools, the cost of these filters is typically lower.

-Inground Pool

In the case of inground pools, the installation costs are generally higher compared to above-ground pool installations, and this holds true for filters as well. Inground pools come with more extensive plumbing, with some of the piping located underground.

To maintain water cleanliness, these pools necessitate more powerful pumps and larger, more efficient filters. Budget between $250 and $2,000 for the installation or replacement of inground pool filters.

-Salt Water Pool

Maintaining a saltwater pool differs significantly from maintaining chlorinated pools, but when it comes to filters, there's no need for a special type. This allows you the flexibility to choose from the available options on the market that are compatible with your pool type and pump. The cost for saltwater pool filters typically ranges from $250 to $2,000.

Filter Type

The prices of pool filters fluctuate based on their type and size. Options include pocket filters, cartridges, sand, DE (diatomaceous earth), and glass filters. While most filters typically range from $250 to $2,000, disposable pocket filters can be as affordable as $30. Cartridge filters generally fall on the lower end of the price spectrum, whereas DE filters are positioned at the higher end.

The least expensive pocket filters are disposable, while higher-end varieties are machine washable. Despite being budget-friendly, pocket filters are less efficient compared to cartridge, glass, or DE filters.

-Pool Filter Cartridge

Cartridge filters, a widely used type, come with a price range of $200 to $1,600. They can filter out debris as tiny as 10 microns, making them less efficient than glass and DE filters. With proper maintenance involving regular cleaning, cartridges typically last two to three years.

-Pool Sand Filter

Sand filters, using #20 silica sand, are designed to filter out debris 20 microns or larger. Priced between $300 and $1,200, these filters have a sand lifespan of three to five years, provided the system is backwashed weekly as part of do-it-yourself pool maintenance.

Alternative sands, such as Zeolite, offer increased efficiency and a longer lifespan of five years, requiring less frequent backwashing than silica sand. Filter glass, capable of capturing debris 5 microns and larger, lasts three times longer than silica sand.

Glass filters utilize a glass media with an electrical charge to capture contaminants. With a cost ranging from $500 to $1,500, they are effective on particles 9 microns or larger. These filters need replacement every eight to 10 years and require backwashing approximately every three months.

-Diatomaceous Earth (DE)

DE filters are the most effective, capturing contaminants as small as 3 microns. The cost for a DE filter ranges from $520 to $2,000. Despite a higher initial price, these filters prove cost-effective over time due to their extended lifespan of 10 years. Additionally, their high efficiency can contribute to savings on electric bills by reducing pump and filter run time.

Maintenance

If you prefer to delegate maintenance responsibilities, consider enrolling in a pool service maintenance package, which typically costs $1,800 annually and may encompass various services, including filter cleaning.

On the other hand, if you enjoy handling maintenance tasks yourself:

-Cartridge Filter

Monitor the pressure gauge on your cartridge filter and initiate cleaning whenever it reaches 8 PSI above the normal range. In addition to routine cleaning two to three times a year, deep cleaning is required one to two times annually.

Unlike sand filters, there's no need for backwashing; instead, use a hose or filter cleaner to spray down the cartridge and soak it in a solution of diluted muriatic acid ($12) or a pool filter cleaning solution ($20).

-Sand Filter

Perform weekly backwashing for sand filters and replace the sand every three to five years. The cost for a 50-pound bag of #20 silica sand ranges from $15 to $40. The quantity of sand required depends on the filter size.

-Glass Filter

To maintain the integrity of glass filters, consider cleaning the glass components on a weekly basis, or increase the frequency to twice a week during the peak summer months. Backwashing the filter every three months is also recommended.

Unlike sand and DE filters, there's no need to replenish anything to ensure the filter's functionality.

-DE Filter

For DE filters, it's essential to backwash them monthly during the swimming season, but it's advisable to check local regulations to ensure there are no specific requirements in your area.

Following backwashing, add back 80% of the required DE for a new filter. As a point of reference, a new filter typically needs 1 pound of powder for every 10 square feet. A 25-pound package of DE filter powder is priced at $30, so depending on your filter size, a package may last around a month or slightly longer.

DE filters also call for a thorough annual cleaning to maintain optimal condition. This involves disassembling the unit for a comprehensive cleaning. Unless you possess experience in this task, it's often best to enlist the assistance of a professional for cleaning DE filters. Additionally, it's recommended to clean the grids every two to three years.

Filter Size

Selecting an appropriately sized filter is crucial for optimal compatibility with your pump. If the filter is too small, it can lead to overworking the pump, potentially causing premature wear on the pump motor.

Conversely, a filter that is too large is generally acceptable. While larger filters may come with a higher upfront cost, many individuals opt for a size that aligns with their specific needs. Larger filters often require less frequent cleaning and can contribute to extending the lifespan of your pump.

To determine the recommended filter size based on your pool's volume, consult the table below. Each filter type is rated in square feet, although the calculations may vary.

For instance, for a 10,000-gallon pool, a sand filter should be rated for at least 3 square feet, whereas cartridge filters should range between 100 to 200 square feet. This discrepancy arises because a sand filter typically requires a minimum of 1 square foot per 10,000 gallons of water, while cartridge filters necessitate 100 square feet per 10,000 gallons of water.

Installation Labor

The labor cost for replacing a pool filter typically ranges from $110 to $140. It's important to note that these expenses do not cover potential plumbing or electrical requirements. If plumbing services are necessary, plumbers charge between $45 and $200 per hour, while electricians typically have hourly rates ranging from $40 to $100.

Alternatively, some pool technicians offer comprehensive installation services, encompassing electrical and plumbing aspects, at rates ranging from $75 to $100 per hour. This option provides a convenient solution for addressing all your installation needs with a single professional.

The overall expenditure for a pool filter is primarily determined by the type you select. When evaluating your choices, it's beneficial to pay attention to the filter's micron rating, as a lower micron value indicates greater effectiveness in capturing contaminants.

Pocket Filter

Pocket filters, also known as filter bags, are the most economical option, ranging from $30 to $100. Their straightforward do-it-yourself installation eliminates the need for labor expenses. These filters can effectively capture contaminants as small as 15 to 20 microns.

Pool Pump Replacement

If you find yourself in need of a pool pump replacement, it often coincides with the timing of a filter replacement. The cost for this replacement can range from $500 to $2,820, contingent on the type of pump you choose.

Skimmer Box Installation

The skimmer box, designed to capture large debris before it reaches the filter, may require replacement if the basket becomes cracked or damaged over time. Acquiring a new skimmer box typically ranges from $5 to $35.

Service Fees

Typically, pool maintenance packages encompass the cost of pool filter maintenance within an average monthly fee ranging from $95 to $260. Your pool technician will handle filter cleaning, including regular backwashing for sand, DE, and glass filters.

For those inclined to handle regular filter maintenance on their own but occasionally seek professional assistance, expect to pay between $60 and $125 per visit. The cost varies depending on whether you require a basic clean or a deep clean.

Cost of DIY Pool Filter Replacement

If you opt for a do-it-yourself approach, the pool filter replacement cost is limited to the unit itself, ranging from $250 to $2,000. While replacing a pocket filter is relatively straightforward, other filter types may demand some manual effort. When dealing with high-value pool filters, ensure you possess the necessary expertise to avoid inadvertently breaking or damaging the filter during installation—a costly mistake best avoided.

DIY Costs vs. Hiring a Professional

Choosing the DIY route allows you to save on labor costs, typically ranging from $110 to $140 for a like-for-like filter replacement. Additionally, you will need to cover material costs, including replacement DE and sand filters. However, cartridge and glass filters only necessitate a cleaning solution.

For those contemplating a switch in pool filter types, it's advisable to engage the services of a local pool professional. This ensures comprehensive assistance, from the removal of the old filter to updates in electrical and plumbing systems.

How to Save on Pool Filter Costs

One way you can potentially save on your pool filter costs is by bundling it with your pump installation. Since the two components work together, this can be advantageous so you can make sure everything runs smoothly.

Secondly, you might consider putting in the extra upfront costs for a longer-lasting filter. For example, a DE filter is more costly than a cartridge filter, but the DE filter lasts 10 years, while the cartridge filter is only good for two to three years.
