I have a 24ft round, 52" high above ground. Which Hayward Cartrige Filter would be appropriate ? Thx

A  Answered on 10/13/2022 by InyoPools Product Specialist Craig C.

Hello John.  The volume of an above-ground pool with the dimensions of 24' round, 52" height is approx. 14,700 gallons.  The Star Clear Plus 120 Sq Ft. Filter 2" Ports - W3C12002 would be an appropriately sized cartridge filter.  Attached please find a brief tutorial How to Size an Above Ground Pool Filter

Is this pump suitable for a 25,000 gallon inground pool ?

A  Answered on 5/31/2021 by InyoPools Product Specialist Craig C.

Hello.  In order to make an appropriate recommendation additional information is necessary.  Your question refers to a pump but the attachment identifies a filter.  Are you looking for information concerning a Pool Pump or a Pool Filter?  If it is a question of filter sizing for a 25,000-gallon pool, then the Hayward Star Clear 50 sq ft is NOT an appropriate size for this pool.  Filter sizing is dependant upon a number of factors.  Please review the attached brief tutorial for some quick fundamentals.  As a rough estimate, solely based on the 25,000-gallon volume, a Hayward SwimClear Large Capacity Cartridge Filter model C3030 would seem more appropriate.    How To Size a Pool Filter   Hayward Swimclear Cart.

In a new installation, please recommend the appropriate filter type and details for an exercise pool 14x7x4. The temp will be around 85 degrees, indoor installation. Light bather load.

A  Answered on 10/27/2020 by InyoPools Product Specialist Joe S.

Hello JJ, we would recommend the ProClean Plus 100 sqft Pool Cartridge Filter - PCCF-100.

Do you carry a filter nut for my Proclean Plus PCCF-200 Waterway filter? The clear opening at the top is 11 inches. My Phone #: 239-450-7178

A  Answered on 1/13/2021 by InyoPools Product Specialist Megan C.

I am not certain which nut you are referring to for the Waterway Pro-Clean Plus 200 Sq Ft Filter - PCCF-200 to provide a specific part number. We offer the parts to the filter, you may view them here http://www.inyopools.com/parts_waterway_proclean_plus_cartridge_filter_.aspx

will this work with my existing 1 1/2 hp motor

A  Answered on 12/8/2020 by InyoPools Product Specialist Hector F.

Hi Jack, this filter will likely be too small however there are a number of variables to consider when sizing an filter. Here is a guide that we put together called "How To Size a Pool Filter" that should assist with that.

will the pl 1500 pump be compatible for this filter my pool is 18" round 52"height repriev ?

A  Answered on 6/30/2019 by InyoPools Product Specialist Lennox H.

Hi, Ramon. Using the PL1500 - 3/4 HP Pump with this size filter will not be efficient. The C900 model will be more efficient.

Hi I have a 12x24 rectangle pool. Shallowest is 4ft deepest is 6ft. I have the Hayward SP3210EE TriStar 1-HP Energy-Efficient Pool Pump. Will this filter work with my pump? Thank you.

A  Answered on 10/12/2017 by InyoPools Product Specialist Lennox H.

Hi, Jeff. This filter will work only if your pump water flow output is less than 50 GPM. I would recommend using our How To: Size a Pool Filter guide to find out what size filter you will need for your pool. You can also call us at 407-834-2200 if you have any questions.

I have a 33000 liter swimming pool and an Hayward C500 cartridge filter is this okay or not

A  Answered on 7/4/2017 by InyoPools Product Specialist Lennox H.

Hi, Ben. This filter can filter 33000 liters of water. However, the inlet flow rate must not exceed 50 GPM.

What is the width of the base on the c500 and c900

A  Answered on 7/2/2017 by InyoPools Product Specialist Lennox H.

Hi, Johnny. The C500 base is 9-1/2 inches and the C900 based is 13-1/2 inches.

Will this replace a Hayward ec45 . Looking to get away from de

A  Answered on 6/29/2017 by InyoPools Product Specialist Patrick P.

Hi Nick, This would replace an EC45 but if your pocket book can afford it I would suggest something a little larger like the Hayward C751 75 Sq. Ft. Filter as you will get longer life out of your cartridges, longer times between cleaning your cartridges and you will put less stress on your pump resulting in a longer pump life.

i have a HAYWARD DE2540 filter will this filter work in replacement ?

A  Answered on 5/18/2017 by InyoPools Product Specialist Lennox H.

Hi, James. This 50 sq. ft is not a suitable replacement for a DE filter. I would recommend the Hayward Swimclear C2030 or C3030 model.

I am making a portable filter for pool service. Is this an acceptable/recommended filter to be used with a 1hp pump motor? What are the dimensions of filter?

A  Answered on 3/23/2017 by InyoPools Product Specialist Lennox H.

Hi, Curtis. This filter is too small to be used with a 1HP pump for a portable filtration unit. The physical dimensions are 29-1/2"H x 10-1/2"W.

I have a 21 foot above ground pool with roughly 10300 gallons. My pump is a Hayward SP15932S Power-Flo Matrix 1-1/2-Horsepower 2-Speed Above-Ground Pool Pump which I keep mostly running on low. Would this C500 filter be adequate or not? If not, please propose adequate cartridge filter.

A  Answered on 7/26/2016 by InyoPools Product Specialist Scott W.

Could you give me an estimate of how from your pump is from your main drain. I'm just estimating the flow rate so I know if that filter is able to handle the flow rate from that pump.

?     Asked on 5/30/2016by BILL GRAHAM


A  Answered on 6/3/2016 by InyoPools Product Specialist Lennox H.

Hi Bill, This filter can filter up to 24,000 gallons in an 8 hour time frame.

I currently have a C 800 Filter and Cartridge, can i switch to a C 500? Pete

A  Answered on 5/9/2016 by InyoPools Product Specialist Lennox H.

Hi Pete, It's not worth going to a smaller filter, I would better if you switch to the C900.

I have a pool spa combo with 15000 gallons. What size cartiridge filter system do you recommend

A  Answered on 3/17/2016 by InyoPools Product Specialist Lennox H.

Hi John, We do not have the proper info to recommend what size filter is needed for your pool. You can follow the steps in our How To: Size a Pool Filter to find out what size filter is needed for your pool.

?     Asked on 6/24/2015by Inyo Visitor

What size pump is needed for this filter?

A  Answered on 6/24/2015 by InyoPools Product Specialist Brian M.

The filter is not intended to accommodate more than 50 Gallons Of  Water per minute.  A 1/2hp Hayward PowerFlo II Single Speed Pump would just be a little higher, but is the lowest I can find.

?     Asked on 10/1/2014by Guest

Are there specs on how many microns this filter is rated at? Is there available another filter that won't allow finer particles to pass through?

A  Answered on 10/1/2014 by InyoPools Product Specialist Patrick P.

As a rule, sand filters sift particles ranging from 20 to 40 microns in size.  Cartridge filters can sift particles as small as 10 to 20 microns in size.  DE filters can sift contaminants as small as 1 to 3 microns in size. This makes DE filtration at least five to six times more efficient than sand filtration systems.

?     Asked on 9/21/2006by Guest

Does this come with the filter cartridge and gauges?

A  Answered on 9/21/2006 by InyoPools Product Specialist Patrick P.

This filter comes direct from the manufacturer and includes the cartridge and gauges.
