Our top cartridge pool filter is the Intex 28633EG Krystal Clear Cartridge Filer for the above ground pool owner. There are many reasons why this pool filter steals the number one spot, price being one of them. If you are looking for an affordable option to get your pool up and running, you have found it.
That particular filter is designed for pool sizes greater than 4,000 gallons and less than 15,000 gallons. The pump flow rate on this filter is 2,500 gallons per hour, with a system flow rate of 1,900 gallons per hour. With a cartridge filter, you are in for a treat when it comes to maintenance. This cartridge needs to be rinsed with your weekly pool maintenance and replaced every few weeks. It’s rather simple.
This Intex filter has a built-in timer so you can set this to run as often as you need to keep your pool looking clean and bright. This filter uses Hydro Aeration technology to add air to the pool, which will break up large clumps of particles and send them to the bottom. Once on the bottom, the filter and vacuum system can do their job to keep the pool looking great. The installation of this pump is speedy, and you will be up and swimming in no time. With the 110-120V electrical hookup, this is not a filter that would need a professional to install.
The Intex 28643EG Krystal Clear Sand Filter is the best sand filter we can find for an above ground pool. This filter will work for pool sizes starting at 5,000 gallons and going all the way to 19,600 gallons. Indeed, this would fit the need for most above ground pool owners.
If you are not a fan of a cartridge filter and can’t be trusted to change it every few weeks, the sand filter could be a much better option. Sand filters should last about 5-6 years before having to be replaced. Sand filters are the most common type of pool filter available because of their fair cost and ease of use.
In addition to being affordable and easy to use, sand filters are quite effective as well. They are outstanding, picking up algae and dirt. Just as our favorite option for a cartridge filter, the best sand pool filter also has a built-in timer and a safety shut off.
The pump flow rate on the Krystal Clear Sand Filter is 3,000 gallons per hour, and the system flow rate is 2,450 gallons per hour. Priced quite a bit higher than the cartridge filter, keep in mind that you pay upfront for a sand filter, but you will own an option that will keep your pool looking crystal clear for several years.
If you are partial to a D.E. Pool filter, we have a perfect option for you. This Hayward model is designed to clean a 20 square-foot area. If your pool is larger than this, there are other models of this particular filter that may suit you better.
Some consider D.E. to be the most effective filter media. One of the best things about D.E. is not having to backwash the pool like you do with the sand and cartridge filter. The Hayward model as an exclusive flex tube design to help reduce the D.E. powder.
This filter requires 4 pounds of D.E., which you will need to replace at times. Installing this filter is not difficult with the easy access clamp that comes included. A D.E. filter costs more than a cartridge, but the difference in water clarity can be seen almost immediately.
Although a few of our other top choices work for above-ground pools, this is the one that we consider the overall best. The good news with this filter is that if you like it, it also works well in small in-ground pools and pond/aquariums as well.
This Hayward ProSeries is a sand filter. The majority of homeowners are still using sand filters. They are relatively simple to operate and not tricky to install. The weekly backwashing is easy with this Pro Series Sand Filter because of a self-cleaning system featured in this unit. This system provides fast flow and a balanced backwash. The valve is also quite a bit bigger making backwashing and closing the pool for the winter quick and easy.
The Hayward ProSeries requires 150 pounds of sand that will not be included with your purchase. Keep that in mind, when calculating the total cost of this unit. The exterior of this unit was built with double corrosion-proof material to ensure that it will hold up in all weather conditions. If you want a solid traditional filter for a fair value, this is the one.
Fifth on our list of best pool filters is another sand option. This SUNCOO sand filter is slightly smaller than the Hayward ProSeries that we discussed in our previous review. Where the Hayward holds 150 pounds of sand, this SUNCOO holds up to 45 pounds.
This pool filter works best for pools of less than 10,000 gallons, and the pricing reflects that. This is another corrosion-proof model that is capable of being left outside in various weather conditions.
SUNCOO paid particular attention to the sound on this unit, making it one of the quieter sand filter options available. The four-way valve makes this filter easy to backwash. Just like the other models we chose for our list, the SUNCOO is easy to install and quite effective at cleaning your smaller pool.
Another sand filter for you. Have you caught on that sand filters have quite a few benefits to them?
This XtremepowerUS 75141 Pool Sand Filter is a perfect option if you have a more substantial above ground or inground pool. This is a sturdy unit that is accustomed to dealing with flow rates and cleaning responsibilities of a large pool. Unlike the smaller SUNCOO model we just discussed, this XtremepowerUS has a 7-way multi-port valve.
An easy to use and durable valve is essential on a sand filter because of the frequent backwashing required. If it is difficult to use and causes you leaks and other headaches, you are much better off going with a high-quality machine that has better parts. This XtremepowerUS Pool Sand Filter has a seven-way valve.
The seven different settings include filter, backwash, winter, re-circulate, closed, rinse, and waste. If you are the one handling your pool maintenance, this filter makes it rather simple.
The tank is a bit of a beast. It holds three hundred pounds of sand and is over thirty-five inches high. Make sure you have ample space before purchasing this filter. This filter works well with and accepts most pumps, making for a quick and easy installation process.
The R.X. Clear Radiant Complete Sand Filter System is an option for above ground pool owners. This package includes a pool pump, tank, hose, and fittings. Although this is a sand filter system, it has everything you need to keep your pool looking perfect.
Priced slightly higher because of all that it includes; this package deal does not come with a variable speed pump; it is just a single-speed pump. This filter is easy to install, and many homeowners can do it without the help of a professional. The filter unit has a six-position valve to help with maintenance and winterization procedures. Like any sand filter backwashing is necessary, any time that is made easy by the features on the filter unit that is a plus.
The see-through screen on this filter is a nice benefit. When you do your daily pool checks, it takes a glance to look in and make sure there is not large debris or clogs that are stopping the filter from working correctly. It’s an excellent benefit for a homeowner that is doing their pool maintenance.
If you have been waiting for the inground pool filter that will hurt your wallet but clean your pool, you have found it. The Pentair 145201 Tagelus Sand Pool Filter is built for an inground pool but would work on larger above ground pools. This is a sand filter option that does not come with the sand needed to get you up and running.
Similar to the R.X. Clear model for above ground pools this filter comes with a see-through glass to make filter inspection easy. That, combined with the 6-position valve, will make this filter easy to care for. If you plan on installing this filter yourself, keep in mind that it will require 600 pounds of sand. It’s a project that you may want to recruit the help of a friend!
Part of being an in-ground pool owner is acknowledging and accepting that it is going to be more expensive. Although this filter costs more than some other options, it is big enough and strong enough to get the job done. One of the things to watch out for on this filter, and any filter you purchase is to do a thorough inspection of the product when it is received. Look for small cracks and imperfections and make sure to contact the manufacturer immediately; you do not want to get to the last step of installation and find these issues.
Now that we have given you some top options for a new filter, you need to narrow down what works best for you. Here are a few things that we think you should consider before pulling that trigger.
When it comes time to purchase a pool filter, you will be left to choose between three different options.
The three options are sand, D.E., and cartridge. Some people swear by the cartridge, while others would never change from a sand filter. There is a little bit of personal preference involved, but you should at least know the difference between each type before making your decision.
When you are choosing a filter, you want to be very sure of the size of your pool. If you select a filter that is not big enough for your pool, you will never have a clean pool. If you can afford a larger filter, you should go for it. You will come across less issues, and the pool filter itself will be under less pressure to perform. If you have a 10,000-gallon pool and you go for a machine that will clean up to 10,000 gallons, know that the strength of this filter will be borderline for your needs. If you can afford it, choose something that will clean from 10,000-20,000 gallons, and you will see a big difference in your water clarity.
Most filters come with a timer and an emergency shut off valve. These are both excellent features to look for should you run into a problem at some point. Keeping your filter on a schedule using the timer is the only effective way to know that your pool is getting the filtration that it needs to stay clean and clear. Don’t try and remember to put your filter on, or use it when you think the pool needs it. Set a schedule and stick to it; you will encounter very few problems doing it this way.
Like anything else, pool filter buying is a “you get what you pay for” type situation. The best possible thing you can do for yourself is to make sure you are buying the right filter size for your pool. If you can save a little money and get something for a smaller pool, don’t do it!
When it comes to cost, try to keep in mind that there will be additional costs associated with each filter type. With a cartridge filter, you will need to replace cartridges. With a sand filter, the sand will need to be replaced every three to five years, depending on how often you are using your pool. The D.E. filter will need D.E. powder, and if a screen on the filter has an issue, it can be expensive to replace.
If you need a low-cost filter to get you through a season, there are plenty of options on our list that will do the trick.
Depending on which of the three filter types you choose, there will be varying levels of maintenance involved. When purchasing the filter that you think is the best fit for you, do a quick read-through of the manufacturer’s maintenance recommendations. If they are suggesting a bi-weekly cleaning/backwash, make sure this is something you will be willing and capable of doing. Regardless of what filter you go with, there will be weekly, monthly, and annual maintenance that needs to take place.
When you choose the model that you know is the perfect fit for your pool, be sure to read what is included with the purchase. Some filters come with hoses and fittings that you will need, and others will come with nothing, and you will be responsible for figuring this out when you get your unit. If you are not good at playing with plumbing and valves, make sure you are getting something that will easily fit into or replace what you currently have.
When it comes to choices, you have to make in life; this pool filter one can be kind of a pain.
Whatever decision you make, you will be living with for the next five to ten years. Choose something that will work with your schedule, the individual needs of your pool, and your budget. Get the most powerful machine you can within your price range, to keep algae and other issues away. We gave you reliable options for cartridge, sand, and D.E. filter replacements. Now it is up to you to decide which one to go with!
