Pool filter types

Currently, there are three types of pool filters available in the market. There exist some other type also, but these three are being massively used in pools all over the world.

These three types have different abilities. I meant, different strong zones of filtration. So, which suits you the most? To determine that, you should have a basic overview of these three types in possession.

Know which type you want already? You can click on your desired pool filter type, to jump to corresponding sections.

  1. Sand pool filters
  2. Cartridge pool filters
  3. DE pool filters

These are the three types I mentioned above. These three have their strong zone, let’s be apprised about them.

Sand pool filters
use sands as the filtration media. As sands are inexpensive, the maintenance cost of these filters is on the lower side. The more bright side is the filters themselves are inexpensive too. So a basic pool filter seeker should try sand pool filters for their personal pool.

Moreover, there are various alternatives to sands you can use in the same filter machine. So you can diversify your filtration quality if you want.

Cartridge pool filters
use some cartridges inside the filter machine. These cartridges are made of a substance called Polypropylene. These filters are pretty inexpensive too, cheaper than the sand filters actually.

So, personal pool owners who want the cost at a minimal side, cartridge pool filters are a good choice to start. The maintenance of these filters is a lot of work though. I will tell more about this at the end of this article.

DE pool filters
use very tiny algae-like organisms. These are called diatomaceous earth, in short D.E. These filters are capable of doing the most efficient filtration. So, commercial pool owners should look into these.

N:B: D.E powders are kind of corrosive. Make sure that you are allowed to use these filters in your area. To know more about this, you may check here

Best pool filters

Now, I will be saying about some pool filters worth checking. These are handpicked regarding durability, performance and ease of finding accessories and warranty.

I have suggested three pool filters for each type.


N:B: – Do not go for less-known filters because finding accessories like O-ring, clamps, etc will be difficult then.
Hassle-free warranty is a must because this ensures that your purchased filter is designed to survive throughout the warranty period even with the very extensive usage.

Sand filter for pool

Sand filters are ideal for moderate filtration with easy maintenance, where the price is on your side.

Pentair Triton II Side Mount Filter TR100 Fiberglass Sand Filter without Valve

This is the most sophisticated sand pool filter currently available and the best you can get. In this model, Pentair has used its patent-protected ClearPro technology. Usually, I do not fall for this kind of verbose names manufacturers give. But here, the ClearPro is the real deal. And visibly, it provides cleaner water than the usual.
Usually, it is said that sand filters can filter particles down to 20 microns. But the truth is it is 50 micron and in some filters, this number can be up to 100 microns.
Anyway, here, the Triton II with its ClearPro Tech – is capable of filtering particles down to 5-10 microns truly.

Wondering what this ClearPro Technology is? There is a proprietary porous tube inside the filter. Water passes through this before re-entering the pool. This proprietary component creates blockades for that smallest debris which snuck through the filtration provided by sands.
This filter provides the same clarity as a regular DE filter would.Pentair Triton II clear pro technology

De powder for pools

Let’s get notified about some DE powder for DE pool filters. In case you do not know yet, you will have to add DE powder at the end of every time you clean your DE pool filter.

How to choose a pool filter?

If you are still wondering that which would be wise considering your pool, you should check my suggestions below before buying.

There are some important aspects you should consider before buying your pool filter.

  1. The size of your pool
  2. Expense
  3. Ease of maintenance
  4. Filtering capability
  5. Lifespan

Swimming pool size

Buying a pool filter syncing your pool size is a must. Always try to buy at least one step bigger filter because a bit big filter means it can handle more water than your pool holds. If it is smaller than it should, it cannot handle the water properly and the final result? A dirty pool.

People often ask me,

“What size sand filter do I need for my pool?”
So now, let’s figure out what sized filter you should buy. Anyway, this procedure is not only confined to sand pool filters. You can purchase your desired type of pool filter using the instructions given below.
Determining the size of your pool correctly is your very first task. And it is important. You just simply measure the volume of your pool. Usually, pool filters have a volume declared on their packaging. That points out to the volume of the pool where this filter should be used.
If the volume is not declared anywhere, the flow rate would be declared must. You’ll have to measure the flow rate of your pool then.
Measuring the flow rate is simple. You’ll have to measure the turnover rate first. It is the total time required to circulate the water to your pool. Then simply divide your pool’s volume with the turnover rate.
Another question I get is
“what size cartridge filter for 20000 gallon pool?”
To answer the question simply, you will have to install a cartridge pool filter over 300 sq.Ft at least.
About cartridge filter sizing, try to use the largest filter possible. Filter filled with large cartridge means bigger dirt holding capacity, means longer period you can go without cleaning the cartridge(s).
This theorem is the same for DE filters, go as big as possible. If the budget does not support, then do all sort of maths and buy one size bigger.

Cheap pool filters

Next comes the expenses. Here I have counted both the price of filters and their maintenance cost in expenses.

Cartridge pool filters are the cheapest option. Cartridge filters themselves are low-priced. And if you clean the cartridges when you should, the filter will last for at least 2-3 years.

In term of being cheap, sand pool filters come next. In my opinion, sand pool filters are the most balanced pool filter than a cartridge filter while you have the price in your mind.

Although, cartridge filters are cheaper than the sand filters. But cleaning the cartridges regularly is really hard work. On the other hand, cleaning sand pool filters are a walk in the park comparing to the cleaning of cartridge pool filters.

DE pool filters are the most expensive pool filters, but they have the most efficient filtering capability.

Pool filter maintenance

This is a very important factor to consider before purchasing a new pool filter. Cartridge pool filters are the hardest to maintain cause cleaning the cartridges are a real pain in the ass. Comparing to it, sand pool filters are easier to clean. Moreover, sand filters last long; almost five years.

The cleaning procedure of DE pool filters is almost identical with the sand pool filter cleaning procedure. But you’ll have to add additional DE powders each time you clean the filter. Since DE powders are a bit hazardous, proper caution should be taken while cleaning a DE filter.

Pool filtering efficiency

Usually, sand filters can filter 20-40 micron where cartridge filters can filter particles above 10 microns. DE filters are the winner in this segment because they are capable of doing the most effective filtration. Particles above 5 microns are filtered by a DE filter system.

Recently, however, filterglasses are used as a sand alternative in sand pool filters. And using such, you can filter 5 microns with your sand pool filter. If you want less work with more efficiency, sand filters filled with filterglasses is your option.

Pool filter lifespan

Sand pool filters are known to be the most long-lasting. 5 years on an average. Cartridges and the DE filters usually serve for two-three years.

Anyway, this does not mean that your pool filters will be completely destroyed by the above mentioned time period passes. If cleaned regularly, these filters will serve you more than you anticipate.

Eco-friendly pool filter

DE powders, which are used in DE pool filters are hazardous and corrosive.

A lot of water is wasted during the procedure of cleaning both DE and sand pool filters.

If you do not want this, cartridge pool filters are your best option.

That’s it. I think you’ve already decided which pool filters will be the wise choice for you. Let me get you back to the filter choices. Please go with what describes you the most.

Looking for easy maintenances?


Special Segment: Pool filter hack

Here, I will talk about some pool filter usage hack. Well, I am not going to discuss how you should maintain your pool filter or how you keep your kids away from polluting the water.
If you are looking for a pool filter which requires little to no work at all, you will find this segment useful.
Say, you are fond of sand pool filters. I mean, why not? Sand pool filters are placed at the top in term of longevity, cleaning sand pool filters is easy. Moreover, sand filters can be mounted on top or side of something. But you are not quite happy with the filtration performance of it. You can use filterglasses instead of sand.
Filterglasses are very finely cut tiny glasses. This enables your sand pool filter to filter about 5 microns, almost the same as DE pool filters. Filterglasses are a bit expensive but it is required only 20% of the amount of sand needed. So, at the end of the day, it is not so expensive.

Cleaning and maintaining pool filters time to time is arduous work. If you want to purchase the reduction of work, you can do that.
Cartridge pool filters are your bet here. Though, cleaning cartridges are serious work; you can simply change the old dirty cartridge with a newly bought one. Voila! Your pool filter has now the newest condition. If you do not want to change the cartridges often. Buy a bigger cartridge filter than what your pool requires. Bigger cartridges can hold a bigger amount of dirt.
So? Get your recommendation? Let me get you back to some best cartridge pool filters then, just click here.
