The Pentair Quad DE 100 sq ft In-Ground Pool Filter 188594 provides the highest level of filtration out of all the filtration types available. The Quad DE 100 sq ft is capable of filtering out particulate as small as 5 microns. That's the same size as a human red blood cell. The 188594 Quad DE 100 uses a set of 4 cartridges coated in pool grade diatomaceous earth to provide filtration.The cartridge dimensions are 32.75" x 6.25" x 6.25" with a 3" center hole. The Quad DE tank is made with fiberglass-reinforced polypropylene that enhances durability and product life. It uses a hi-flow manual air relief valve that eliminates air buildup in the tank rather than having it force back through the system. A 1-1/2" drain is used for quick drainage, and a steel tension control clamp rests securely around the tank, a brass barrel nut securely fastens each half tightly together. To remove the 188594 Quad DE lid it requires a minimum of 74" vertical clearance. Before removing the dome lid, it is suggested to backwash the filter to discharge the contaminated DE powder.
What are the dimensions of the tank?
Tank Dimensions: (DxH) 21.5" x 55"

What is the max GPM flow rate?

What does 188594 Quad DE 100 sq ft come with?
The 188594 Quad DE 100 sq ft comes with the tank, steel clamp, air relief valve, and threaded bulkheads.
D.E. Filter systems cut energy costs by using lower pump pressure and speeds. If properly taken care of and rinsed regularly, they can significantly reduce water use. In addition to cost savings, lower pump pressure can help prolong the life of your pool pump!
D.E. is a natural substance that captures dust, dirt and debris as small as 5 microns. A D.E. filter system removes body oils, suntan lotions, pollens, dust, and even some bacteria, making your swimming pool a healthier environment.
A D.E. Filter maximizes the useful filtration area. A larger filtration area means longer periods between each cleaning, saving you time on pool maintenance and giving you more time to relax and enjoy your pool.

Replaced sand filter
Review by Brad G. on 21 Apr 2020review stating Replaced sand filter
My water is clearer then ever. Became crystal clear after the first day of filtering. My pool is 16k gallons, only needed the 60 ft^2 but bought 100 ft^2 to minimize maintenance. I’m happy about my purchase.

Are you running a sand filter currently? GET THIS FILTER
Review by Logan M. on 17 Jul 2018review stating Are you running a sand filter currently? GET THIS FILTER
My pool was built in 1964. It has had 5 different sand filters since it was built. I am the grandson of the first owner and I simply became tired of not having truly polished, sparkling water. I started using a robotic cleaner about four years ago which greatly improved the quality of the water as it was able to filter even finer particles than the sand. Two weeks ago, I ordered this filter from the same company that built the pool in 1964. (That fact is a blessing in and of itself) I am their first client to have one of these filters installed. In 14 hours, my 54 year-old, 38,000 gallon gunite pool became CRYSTAL Clear. I have seen this phenomenon occur only a handful of times in my life with this pool and I can assure you, its been a freak accident up until this point with a sand filter. By the time a sand filter becomes really great at filtering, it is practically clogged. You then backwash and start back over with a filter that works about as well as a kitchen strainer. This filter amazes me. The inherent cloudiness left by my sand filter (with perfectly balanced water) is GONE. I am running a chlorine system, not salt, but my chemical consumption has cut in half. Why did I choose this over over a traditional cartridge or DE Filter? Because I love the ability to backwash and then simply recharge without having to take the entire unit apart to clean it. I typically leave the installation of these types of items to professionals and I did so with this filter. It took about 2.5 hours start-to-finish, including draining and removing the existing sand filter that it replaced. Bottom line: It is my opinion that that this is an exceptional filter and I have been taking care of pools (as an owner, not a professional) since I learned to walk.

Worth the money
Review by Mike on 25 Jul 2015review stating Worth the money
Just purchased to replace an old Hayward 60sq DE filter. Filters with less restrictions from my old filter, and within one day of running a variable speed pump for a day cleaned up a 33000 gallon pool. Very happy with this filter

Review by Miller, A. on 29 Jun 2015review stating Works Great
32000K pool with 3HP Variable speed pump. Keeps pool crystal clear w/ one backwash and DE recharge during swimming season. Quickly turns a cloudy pool clear after chlorine negligence. Highly recommend over any sand filter. DE hybrid filters aren't anymore work than a sand filter. Furthermore, they filter to a much higher degree. Previous review of 1 star is having other issues I don't care to comment on.
