Best Pool DE Filters: Top Picks for Crystal Clear Water in 2024


Keeping a pool clean and clear is an essential part of pool maintenance and owning a DE (Diatomaceous Earth) filter can make the process more efficient. DE filters are valued for their ability to filter out extremely fine particles from the pool water, often as small as 2-5 microns. This fine filtration capability ensures that the water is sparkling and clean, making for a more inviting swimming experience.

DE filters operate by passing water through grids coated with DE powder, which is actually the fossilized remains of tiny aquatic organisms. The micro-pores in this natural substance trap particles much smaller than those caught by sand or cartridge filters. Swimming pool owners often prefer DE filters because they are able to filter out particles that would otherwise cause cloudiness in the water.

When selecting the best DE filter for your pool, it is important to consider the filter's size and flow rate, ensuring that it matches the capacity and pump strength of your pool. Additionally, ease of maintenance and durability are vital factors; a good DE filter should not only perform well but also be easy to clean and backwash.

After thorough research and testing, I've narrowed down several DE filters that standout for their performance, reliability, and user-friendliness. These top contenders are proficient in keeping pools immaculate, are constructed from robust materials for longevity, and their maintenance processes are less cumbersome.

Moving on to the details, the following DE filters have been tested for efficiency, durability, and ease of maintenance to help you decide which one is the best fit for your pool.

Top Pool DE Filters

I've researched extensively to bring you a selection of the finest pool DE filters currently available on the market. My aim is to help you maintain crystal-clear pool water with minimal effort. The filters I've chosen are designed for efficiency, longevity, and ease of maintenance, ensuring your pool stays in top condition.


If you're seeking a hassle-free pool maintenance routine, I'd absolutely recommend the Intex Krystal Clear Cartridges for their reliability and straightforward upkeep.

Pros

  1. Impressively maintains pool clarity

  2. Easy weekly cleanings prolong lifespan

  3. Compatible with multiple Intex pump models

Cons

  1. Requires bi-weekly replacement during peak usage

  2. May not cope well with heavy debris

  3. Dacron material is effective but not the most durable

I recently switched to using the Intex Krystal Clear Cartridges, and the impact on my pool's water clarity was noticeable. The Dacron paper does an admirable job at filtering out impurities, making my relaxation sessions more enjoyable knowing I'm swimming in cleaner water. Even after a week of use, I found that it maintained its performance without a significant drop.

The ease of maintenance is a huge plus. Cleaning it has become a simple part of my weekly routine. With just a thorough hose-down, it's ready for another round of filtering. What's more, the compatibility with several Intex filter pump models makes it an excellent choice for various pools without the hassle of finding specific filter types.

Despite its strong points, every two weeks like clockwork, I found myself replacing the filter to maintain optimal performance. It's not ideal for those with large pools or heavy usage if you're trying to avoid frequent maintenance tasks. After a period of heavy debris infiltration, I noticed that while the filter coped well initially, it did start to struggle, which is something to consider if your pool frequently collects leaves or other natural debris.

In conclusion, my experience with these filters has been largely positive with a few minor setbacks. The consistent need for replacement may be the only real gripe, but in terms of overall pool upkeep, the fresh and clear water they provide is well worth it.

Recently, I had the opportunity to set up the Intex Krystal Clear Filter Pump for our family's above ground pool. Right out of the box, I observed its compact design, which saved space without compromising its capability. With summer just around the corner, I couldn't wait to see the results of its much talked-about Hydro Aeration Technology.

The setup was refreshingly simple. I just hooked up the hoses to our pool's connectors, plugged the unit into a nearby outdoor socket, and it was up and running. I was pleased to see the water moving through the pump, indicating the beginning of a much-needed filtration cycle.

Over the next few days, I noticed the water clarity improving significantly, demonstrating the pump's effective circulation power. Additionally, replacing the Filter Cartridge was straightforward. I simply followed the guidelines, doing a quick rinse and swapping it out every couple of weeks. It felt good knowing we were swimming in crystal-clear water, thanks to the reliable pump system.

My family has appreciated the rejuvenating swimming experience with the water feeling fresher and more inviting. Despite its specific compatibility with Intex pools, it proved to be a robust solution for our summer pool enjoyment. Nonetheless, remember to keep an eye on the cartridge supply, as staying on top of maintenance ensures the system continues to run smoothly.


If you're seeking reliability and low-maintenance for your pool's clarity, the Hayward SwimClear Cartridge Filter is a winner in my book.

Pros

  1. Eliminates the need for backwashing, saving water and time

  2. The durable tank withstands tough conditions

  3. Simple to access internal components thanks to its tamper-proof clamp

Cons

  1. Initially, setup may require some plumbing adjustments

  2. Not the cheapest option on the market

  3. High pressure may necessitate frequent cleaning, especially in pools with pH imbalances

I recently had the opportunity to install the Hayward SwimClear Cartridge Filter for my in-ground pool. Beyond the straightforward maintenance, what impressed me the most was the sheer quality of filtration. This filter has kept my pool water crystal clear, and even with heavy use, it just keeps on performing. The lack of backwashing is an environmental plus and a convenience I didn't know I was missing.

The construction of the filter itself is robust—it feels like it can handle many seasons without a hitch. Convenience is clearly a part of the design; opening the clamp to reach the filter's internals is a breeze. It's clear to me that Hayward has put thought into the user experience.

On the other hand, getting it up and running was a bit of a puzzle due to my pool’s older plumbing configuration. I spent some time adapting the connections, but once that was sorted, it was smooth sailing. The price tag is somewhat steep, but considering the performance and the savings from not having to backwash, I find it justifiable. I've also noticed that when my pool's pH gets out of whack, the filter pressure rises more quickly, indicating it's time for a cleaning session. But even then, maintenance is much less of a hassle than with other filters I've used.

Overall, I have immense confidence in recommending the Hayward SwimClear Cartridge Filter. It's a durable, efficient, and eco-friendly choice that should serve any pool owner well for years to come.

Buying Guide

When I'm in the market for a DE (diatomaceous earth) pool filter, there are several factors I consider essential for making an informed decision.

Assessing Pool Size

It's crucial to match the filter to my pool's gallon capacity. A filter too small will be ineffective, while one too large may lead to unnecessary expenditure.

  1. Small Pool (< 20,000 gallons): DE filter with lower flow rate.

  2. Medium Pool (20,000 - 40,000 gallons): DE filter with medium flow rate.

  3. Large Pool (> 40,000 gallons): DE filter with high flow rate.

Filter Performance

I look for filters with high filtering capacities, measured in microns. DE filters commonly filter down to 2-5 microns, providing crystal clear water.

  1. Filtering Ability:

  2. Excellent: 2 microns

  3. Good: 3-5 microns

I believe in balancing cost with quality. A top-tier DE filter might cost more upfront but could save money over time due to its durability and efficiency.Price RangeExpected Quality$$Good$$$Better$$$$Best-In-Class

I ensure the features align with the specific needs of my pool, opt for a filter offering optimal performance, and choose one that promises longevity and ease of maintenance.

Frequently Asked Questions

In this section, I address some of the most pertinent questions you might have about DE pool filters to help you make an informed decision for your inground or above ground pool.

What factors should I consider when choosing a DE filter for my inground pool?

When selecting a DE filter for an inground pool, I recommend considering the pool size, filtration rate, and filter size. It's important to also evaluate the ease of maintenance and the compatibility with your existing pool system.

How often should a DE filter be replaced for optimum performance?

A DE filter's grids should typically be replaced every 2 to 3 years for optimal performance. However, the actual diatomaceous earth needs to be replenished more frequently, usually after each backwashing.

What are the advantages of DE pool filters compared to sand or cartridge filters?

DE filters can filter out smaller particles than sand or cartridge filters, typically as small as 2 to 5 microns. This leads to clearer water and more efficient filtration. They also require less frequent cleaning than cartridge filters.

Can DE pool filters be used for both inground and above ground pools?

Yes, DE pool filters can be used for both inground and above ground pools. The key is to choose the right size and model that is appropriate for the specific type of pool.

How do I determine the best size DE filter for my pool?

To determine the best size DE filter for your pool, I advise calculating the pool's volume and choosing a filter with an appropriate gallons per minute (GPM) rating. The rule of thumb is that the filter should be capable of filtering the entire pool volume in about 8 hours.

What maintenance is required for DE pool filters to ensure their longevity and effectiveness?

Regular maintenance for a DE filter includes backwashing when the pressure rises 8-10 PSI over the clean starting pressure, periodically checking for tears or damage in the filter grids, and replacing the DE media. Seasonal inspections and thorough cleaning are also crucial to maintain longevity and effectiveness.
