It can be a tough task, finding a perfect solution to remove sediment and other contaminants from your water.

Well Water has levels of sediments, iron, and other dissolved solids that can cause harmful effects to your health. City Water, though treated, still contains some sediments.

With different products in the market, it can be quite tricky to figure out the best sediment filter.

We curated a list of 5 of the best water sediments filters in the market and a buying guide that outlines features to consider when deciding on one.

Features To Consider When Buying The Best Water Sediment Filter

a) Water Source

Checking your water source is one of the first things you should do before deciding on a water sediment filter.

Water sources have different levels of concentration. For example, well water has higher levels of contaminants compared to municipal water.

Whether you have well water or city water, you're likely to arrive at these two sediment filter solutions:

  • Flushable spin down sediment filter
  • Water filter housing + sediment filter cartridge (PP filter, multi-gradient filter, or pleated filter)

A flushable spin-down sediment filter allows the flushing of collected sediments through the filter's bottom when clogged to maintain its performance and can last for 1 to 2 years with regular cleaning.

Families with high water usage often use the reusable spin-down filter.

Water filter housing and sediment filter cartridges - These can be used for many years. All that needs to be done is for the sediment filter to be replaced every 3 to 12 months, depending on filter capacity, water quality, and usage.

If your main source is city water, you're best suited with a filter with a smaller micron rating. This could either be a spin-down sediment filter or a large capacity-based filter.

b) Type of Sediment

Sediments come in various forms ranging from silt, sand, rocks to remains of plants and animals.

To ensure that you're selecting the best sediment filter, it's important to know the type of sediments present in your water.

This is essential as some filters are designed to deal with certain sediments.

c) Micron Size

Micron rating refers to the size of a filter's pores. To know and select the ideal micron size, it's key to check the sediment type in your water.

Once this is done, pick a filter with a micron size that is bigger than the sediment. This will ensure that the deposits will pass through and will be filtered out.

A micron is a unit of length that is equivalent to one micrometer (1μm). A 1-micron particle means it has 1 micrometer (1μm) in diameter.

Smaller Micron rating (or higher Mesh size) = Stronger filtration = Shorter filter lifespan

Larger Micron rating (or smaller Mesh size) = Weaker filtration = Longer filter lifespan

The smaller the filtration size, the more sediments it will accumulate over time, hence the more often you need to flush or replace it.

A filter with a smaller pore size is better in sediment removal, but the downside is that it gets clogged faster, while filters with a larger pore size filter fewer sediments but last longer.

The frequency of your water filter is dependent on your micron rating. If you prefer a filter with a higher micron rating, this will reduce the frequency of maintenance. A lower micron rating means frequent maintenance.

The best option is to get multiple sediment filters with different filtration sizes and functions that are in line to achieve the best result and filtration efficiency.

Filtration Strength vs. Water Flow Rate

Smaller Micron rating (or higher Mesh size) = Stronger filtration = Slower water flow rate

It's important to keep in mind that you shouldn't install a 1-micron sediment filter as the pre-filter for the whole house as it's inefficient and may need to be replaced every 1 to 2 months.

It will also impact your water flow rate.

It's better to install a sediment filter with a larger micron size on the front line, which is around 10 to 500 micron depending on your water quality, and gradually reduce the micron rating toward your inner house.

Essentially, you're better off using a large micron sediment filter for point-of-entry filtration and a small micron rating for point-of-use filtration.

d) Flushable

Many sediment filters include a flushable feature. The best filter should ideally fit your needs and, if possible, have a back-flushing or spin-down element.

Flushing refers to the process of cleaning your filter and removing the built-up sediment, dirt particles, and rust that your filter has removed from your water.

Various filters can be cleaned by hand; however, this is a messy job that can occasionally lead to breakage if mishandled.

Having a flushable filter means that you ‘rinse’ the filter off every so often to ensure it operates at maximum capacity.

e) Type of Sediment Filter

Reusable Spin-Down Filters

This type of sediment filter is best suited for medium- to large-sized sediments. They are usually used in the pre-filtration stage in multi-staged filtration models.

Reusable spin-down filters feature a filter medium spun around in the middle. The multi-layered design effectively removes and filters out different particles' sizes, ranging from 25 to 1,000 microns.

During the sediment filtration, some of the finer ones are bound to slip in. However, this is not an issue as they will be filtered in the end with the multi-staged filtration model.

Spin-down filters tend to be more durable and long-lasting. They are also easy to clean and maintain. Some models of reusable spin-down filters have their auto-flush valve systems.

Reusable spin-down filters can also support up to 150 PSI in terms of operating pressure and flow rates up to 90 GPM.

Cartridge Filters

Cartridge filters are ideal for filtering out the finer particles that spin-down filters couldn’t tackle. They come into two categories:

1. Pleated Cartridge Filters

These cartridge filters feature a pleated filter medium. The kind of medium varies; however it is usually made from paper, cloth, woven wire, etc. Depending on the model, it can even filter sediments as small as .10 microns.

They are designed to target a large surface area; hence, most people use them either as a pre-filter or stand-alone filtration solution.

Pleated cartridge filters allow for higher flow rates and pressures. Some models come with protection features, thus enabling them to withstand and last for a long time.

2. Spun Cartridge Filters

The difference between pleated and spun cartridge filters lies in depth. Spun cartridge filters come with a filter medium wrapped around the base.

Hence you have a multi-layer that can target various particles of various sizes. They are more effective and versatile. They are also more common, cheaper, easier to use and maintain.

Frequently Asked Questions (FAQ)

What Is A Sediment Filter Used For?

a) Reverse Osmosis

Reverse osmosis (RO) systems require a sediment pre-filter. Reverse osmosis purifies water by filtering it through a semipermeable membrane that removes salts, dissolved solids, and metals.

The sediment filter functions as pretreatment and protection for the Reverse Osmosis system. 

b) Protecting Carbon Filter Lifespans

Carbon filters are known for their ability to restore water’s fresh taste by removing chlorine and chloramines.

Though carbon can filter out sediment, dirt particles can clog up the carbon and quickly exhaust the filter media.

If carbon filters are forced to filter out large quantities of sediment, their filter life is reduced.

Sediment filters are cheaper to replace than carbon filters. Hence, to prolong your carbon blocks' life, it is better to install a sediment pre-filter.

c) Whole House Sediment Filtration

A whole house sediment filtration application can save you a ton of money.

Sediment flowing through your home pipes can cause an absolute detriment to your household appliances.

Your pipes will eventually clog, which will slow down the water pressure and flow in your home.

Appliances like dishwashers and washing machines can experience shorter lifespans.

Sediment filters provide those who depend on well water with the necessary purification and water supply for their household.
