Waterpool filters are like strainers to strain all the dirt from pool water.
Install a pool filter and remove all dirt particles, keeping the pool crystal clear.
In this post, you’ll learn what are the three types of waterpool filters to keep your pool clean. Specifically:

- Need of a pool filter;
- 3 types of pool filters to make your pool bacteria-free;

What is a pool filter?
Sand Filter
How does sand filtration work?
How do you clean a sand filter?
You need to backwash your sand filter when the pressure gauge reading is more than 8 to 10 psi starting pressure. siliceous
First, turn off your pool pump, and then set the control valve in the backwash position and connect the backwash hose to your draining location.
Turn on the pump, the water flow is now reversed through the filter to the bottom of the tank, and the trapped dirt is out of the waste line.
You need to run the pump for 2-3 minutes or until the backwash water becomes clear. Then turn the pump off again and set the valve to its original filter position.
Pros
- Least Expensive
- Simple to upgrade
- Easy to Maintain
Cons
- Constant backwashing can imbalance the chemical level of water
- Needs a sand change every 5-8 years
- It doesn’t filter the smallest particles like a cartridge filter
Cartridge Filter
A cartridge filter is one of the effective filtration devices to filter pool water. Cartridge filters use a replaceable, pleated fabric cartridge to trap wastes and contaminants.
There are two types of cartridge filters to clean your pool water:
- Surface filters
- Depth filters
a ) Surface Filters
Surface filters are the type of filtration system used to capture dirt particles on the surface of the filter. These filters restrict particles on the surface through its thin layers.
How Surface Filters Function:
Surface filters work by allowing water to pass through a porous material. The material may be a fine mesh, fabric, or a thin membrane with tiny openings.
As the water passes through, particles larger than the pore size of the filter are blocked and piled up on the surface of the filter. The trapped contaminants can be washed off from time to time or increased until the filter is replaced.
Surface filters are cheaper than depth filters and have a short shelf life.
b) Depth Filters
Depth filters trap all the dirt elements throughout the entire depth of the filter material, not just on its surface.
These types of filters have multiple layers of filtration media, with different pore sizes. The outer layers capture bigger particles because of larger pores, whereas the inner layers smaller particles because of smaller pores. One of the greatest advantages of a depth filter is that it can hold a large amount of dirt.
These filters last long, filtering performance is great and remove effectively both fine and coarse particles.
Pros of Cartridge Filter
- Remove smaller particles easily as compared to sand filters
- It uses lower pressure, so low power consumption
- Less impact on water chemistry
- No backwashing. Easy maintenance schedule.
Cons of Cartridge Filter
- Expensive to purchase and maintenance costs are also higher.
- Not suitable for larger commercial pools
- Need to replace cartridges every 2-4 years
- Need to open filter and wash cartridges
Diatomaceous Earth Filter
How does a diatomaceous earth filter work?
Pros
- DE filters capture small particles ensuring clean and bacteria-free water.
Cons
- The maintenance costs of DE filters are higher than other types of filters.
- Inhalation of DE dust is harmful. Extra care needs to be taken while handling DE filters.
Which type of pool filter is best?
DE filter is the best because it can catch particles smaller than 5 microns. These types of filters keep your pool water transparent and hygienic. But from the maintenance point of view, they are expensive.
So, it depends on you which one you should buy. There are other filters like sand and cartridge filters. Sand filter is the most inexpensive filter. The cartridge filter is less expensive than the DE filter. Depending on the water quality, filter capability and affordability, choose your pool filter options.
