🧾 Sediment Filter for Well Water Buyer’s Guide

A sediment filter is a type of filter that’s specially designed for removing large suspended particles in water, including sand, dirt, dust, and rust. Read on to learn more about sediment filters and why you may need one for your own well water supply.

🤔 Why Do I Need a Sediment Filter for Well Water?

If you’re at all knowledgeable about water treatment solutions, you may have heard of sediment filters before. Sediment filters are commonly known as pre-filters when they’re included in whole home systems such as reverse osmosis filters. They remove the large particles found in water that can clog up a carbon filter or RO membrane and reduce its inefficiency.

If your home uses a city water supply, you can definitely still benefit from a water sediment filter. But well water typically tests a lot higher for sediment than city water, and that’s because of where it comes from.

While city water is treated and sent on its way through pipes into our homes, well water essentially just comes from a big hole in the earth, which means it’s more likely to contain small particles of that earth in it. Well water with a high level of sediment may be affected taste-wise. These particles may also damage your main water supply line and affect flow rate and water pressure over time.

🔠 Types of Sediment Filters

There are two types of well water sediment filters that you’re most likely to come across today: spin-down and cartridge, both of which can be used at the home’s point of entry.


A spin-down sediment filter is a less common sediment filter that’s particularly effective in well water sediment removal. This filter for well water is installed as a first stage filter, usually before another filter cartridge that’s designed for removing specific contaminants from water, like chlorine or lead. You may hear it referred to as a pre-filter.

You’re most likely to find a spin-down sediment water filter in a whole house filtration system, especially when it comes to treating well water. You want to treat the water as close to its entry point into your home as possible, which will ensure that the main water supply throughout your entire house is clean and sediment-free.

How does it work?

This type of filter is a little different in design than a typical filter cartridge. It looks a bit like a large pipette, and typically has a clear exterior so you can see the build-up of sediment inside.

Spin-down filters are unique in that you can they come with a flush valve, which allows you to quickly and easily remove the collected sediment without having to take the filter out of its filter housing or remove it from your water line.

An advantage of spin-down filters is that they’re easy to install and don’t affect water pressure as noticeably as some other types of sediment well water filter, They come in multiple pipe sizes and can handle water flow from 20 GPM to 80 GPM.

Cartridge Filters

A cartridge filter is probably the sediment filter you’re most familiar with. Cartridge filters are either installed at a water line in their own filter housing, or they share the housing of a much larger multiple-stage filter.

Either way, you’ll usually come across a cartridge filter that acts as a first stage pre-filter before other stages of filtration, whether there are separate cartridges involved or just one big tank.

There are two popular types of cartridge filters to be aware of: spun cartridge and pleated cartridge filters.

How do they work?


Spun-cartridge filters get their name because of their design. They’re cylindrical shaped and are typically made from multiple layers of spun, melted polypropylene. When water passes into a spun-cartridge filter, it encounters a more thorough filtration because of the multiple stages of media it has to travel through.

The very outside later of a spun-cartridge filter is the most porous. It has the highest micron level, which means it can trap the largest particles first, such as grains of sand and dirt. As water continues to travel deeper into the filter, each layer has a lower micron level, making this type of filter capable of removing sediment of all sizes.

You can use a spun-cartridge filter with any filter system, making it one of the best whole house sediment filters in terms of convenience.


Like spun-cartridge filters, pleated cartridge filters get their name because of their design. The media used inside the filter has a pleated, folded design with a high micron rating, enabling the filter to trap the greatest quantity of large particles, like dust, sand, silt and rust.

Pleated cartridge filters don’t tend to be as effective as spun-cartridge filters because they only consist of a single high-micron design throughout. This means they’re pretty useless at removing smaller contaminants from water – but they’re a worthy addition to any whole home water filtration system as a pre-filter.

While it traps large, suspended particles, a pleated filter lets smaller particles pass through. These can then be filtered out by filters with a smaller micron rating, such as activated carbon filters.

⚖️ Which Type of Sediment Filter Should I Use?

Considering both cartridge and spin-down sediment filters have their benefits, how do you know which one is best suited for you?

This all comes down to the quality of your water source. You can find out exactly which contaminants your well water contains, and to what level, by using a basic testing kit. You can then look for filters that are particularly effective at targeting the sediment issues you’re facing.

I also recommend reading over the following considerations and making sure to keep them in mind when it comes to buying your own sediment filter for well water.

💭 Considerations When Buying a Well Water Sediment Filter

Water Source

If you’re on the hunt for a well water filter, I’m going to assume that your home’s main water supply comes from your well. But “well water” is a pretty generic term used to describe a body of water that could be vastly different from one house to the next.

Your location plays a big part in the quality of your water. Different types and quantities of sediment are found in different parts of the world. That’s why it’s wise to test your water before you rush into buying any old sediment filter.

A test will tell you exactly which contaminants are in your water, which will help you to decide on the best sediment filter for well water in your own home.

Type of Sediment

Not all sediment is the same. There are various types of sediment that can make its way into your well water, and you can’t rely on all of the best sediment filters to remove all types of sediment entirely. While benefit from a sediment filter as the first line of defense, using it alongside a whole house well water filter will remove the highest level of all large particles found in your water.

If you’re not sure what the best sediment filter for well water is based on your particular well sediment content, your best bet is to buy a whole house water filtration system that features a sediment filter with a high micron rating, with additional stages following up.

Your Water Pressure

The normal water pressure of a medium family home is between 40 and 60 PSI. You can measure your water pressure using a pressure gauge, which you can buy online.

It’s important to check that your water pressure is suitable for installing a sediment water filter before you actually do so. Many water filters can’t handle high pressure, for instance, which could cause damage to the inside of the system. Low pressure, on the other hand, can affect your home’s water flow rate, because the water is further slowed by the friction it encounters from passing through the filters.

If your water pressure is higher than 60 PSI, it doesn’t necessarily mean you need to figure out a way to decrease it. Some sediment filters are designed to handle a PSI of up to 150. Just be sure to check before you buy if you have specific requirements.

Filter Capacity

Filter capacity is one of the most important deciders when looking for sediment filters for well water. The capacity of a water filtration system lets you know the maximum gallon output of a system, or how many months or years you can expect a filter to last.

It’s important that you change a filter when it hits its maximin filtering capacity, as a filter that’s completely clogged will sediment will slow down your water flow rate massively. This is because water can only pass through the filter at a stunted rate, as the majority of the filter pores are blocked with sediment. To keep water flow rate high in your home with minimum maintenance required, look for a sediment filter with at least a 6-month lifespan.

Micron Rating

The thing to usually in mind with the micron rating of a filter is “the lower, the better”. Microns refer to the size of the filter pores – so the lower the micron rating, the smaller the pores. For instance, a filter that has a 1-micron rating will be capable of removing much smaller sediment than a 5-micron filter could.

But is low really the best for a sediment water filter for well supplies? Yes – but only to some extent. Most sediment filters don’t have a micron rating any lower than 5, and that’s because their goal is to filter out larger sediment. It’s down to the filters that follow on from a well water sediment filter to remove these smaller particles.

Typically, you’ll find the best sediment filter options for well water have micron ratings of 5 to 30. If your goal is to remove sediment and smaller contaminants from water, your best bet is to buy a whole home filtration system, of which a sediment filter is the first stage.

Installation & Maintenance

Installing a sediment filter at your main water line can prove to be something of a challenge. However, most manufacturers design their sediment filters to be easy enough to install by the average homeowner.

Sediment filters alone come with very few parts to worry about. If you’re installing a sediment filter as the first stage of a bigger water filtration system, and you don’t rate your plumbing or DIY skills, you may need to consider hiring a plumber for the job.

In terms of maintenance, there’s usually nothing you’ll have to remember aside from filter changes. Check your filter’s user manual to see how often it needs to be changed, and make sure you keep a stock of replacement filters for when the time comes.

You may also need to flush your filter every now and then, so make sure to check whether you need to do this to keep the filter in good shape.

Additional features

Some of the best sediment filters for well water come with additional features that help to improve their performance and lengthen their lifespan. The flushable sediment filter feature is one of the most beneficial to have.

When a filter has backwashing or spin-down capabilities, it’ll clean out any build-up sediment, preventing it from clogging the filter and ensuring that the water can pass through effectively. Note that most filters with no backflushing element usually can’t be cleaned by hand as an alternative, as this can cause damage to the media.


If your sediment filter comes with a warranty, it’s not only a sign that the manufacturer is confident in the quality of their filter, but it’s also reassurance on your part that you’re covered in the event of a manufacturing fault or accident. Most manufacturers offer multi-year warranties for whole house sediment water filter systems. Make sure to read the fine print of a warranty carefully, as not all are equal.

❔ Frequently Asked Questions

Is well water sediment bad for your health?

It depends what type and how much. Certain types of sediment can be harmful if you ingest a high level of them at once. That’s why it’s important to remove sediment with a sediment water filter, making it safe for yourself and your family to drink.

Are sediment filters capable of removing iron?

Some are, yes. But you can rarely rely on a sediment filter alone if you have high iron levels. While sediment filters are effective at reducing suspended rust particles in water, they can’t remove soluble iron particles. If you’re keen to eliminate iron from your well water, you’re best off using a sediment water filter alongside a whole house filter that is specifically designed for iron removal.

How do you know that a sediment filter is working?

The quickest and easiest way to know if you’re seeing results is to test your tap water for sediment beforehand (which you can do with a test kit purchased online), then test it again after installing the filter.

Is it better to get a 1 micron or 5 micron size sediment water filter?

It depends on what you’re looking for. Generally speaking, when it comes to activated carbon filters and similar, the lower the micron rating, the better. But the whole point of a sediment filter is to remove large particles, which means a 5 micron filter is actually more beneficial. The best solution is to combine a 5 micron size sediment filter with a filtration system that uses filters with a lower micron rating.

When should I opt for a spin-down sediment filter instead of a fine micron sediment filter?

If you have a pretty heavy load of sediment in your well water, you’ll benefit most from using a spin-down filter. That’s because spin-down filters can trap large particles of sediment and sand that could otherwise clog a typical filter and render it ineffective almost immediately. A spin-down filter uses centrifugal force to push dirt and debris into the bottom of the system, which you can release by opening the valve.

What’s the average lifespan of a sediment filter?

This totally depends upon the quality of your water and how much sediment you’re dealing with. Every 3, 000 gallons of water, or 6 months, is the most common period between filter changes. But some sediment filters can last much longer than this, up to 6, 000 gallons of water (every 12 months) or more. You’ll usually be able to tell when a filter needs changing because your home’s water flow will slow right down.

How Often Should I Change My Sediment Filter?

You’ll usually need to change a whole house sediment filter once every 6 to 9 months. Some filters are even better than this, and can last up to a year or longer. The best way to know for sure when your sediment water filter needs changing is to monitor your water pressure. If the pressure drops, it’s a likely sign that you need to change your filter.
