Although sediments are not known to alter the taste of your tap water or the taste of water pulled from a private water well, they do affect the appearance of water, but most importantly, sediments can cause damage in boilers, washing machines and kitchen appliances. Depending on where you get your tap water from, you may have large or fine sediments in your water, an aspect which can be a factor in determining the type of sediment filter you need.

choosing sediment water filter

In this article, we’ll examine the factors you need to consider when choosing a sediment water filter. These are: the purpose of a sediment filter, the micron size and the type of sediment filter.

Why you need a sediment filter?

Before you jump on the bandwagon of purchasing a sediment filter, you need to consider whether you actually need one. If you notice that your tap water contains visually identifiable sand granules or rust, or you have an UV water filter or a reverse osmosis installed in your home and you need a sediment pre-filter to protect the reverse osmosis membrane or to make sure your UV water purifier’s performance is not hindered by suspended solids, a sediment filter can help you to efficiently deal with all these issues.

Hard water problems are often mistaken for sediment problems. If you’re looking to deal with hard water issues, a sediment filter will not help. Instead, you’ll need a scale inhibiting filter. While scale manifests itself through deposits you notice on your kitchen taps, bathroom tiles or other surface due to water’s high mineral content, sediments are silt, sand and rust particles that find their way into your water and cause damages to home appliances.

Sediment filter micron size

In principle, the smaller the micron size of the filter, the smaller the sediments it can filter out. However, if your tap water contains larger sediments, a sediment filter with a small micron size will clog very easily and you’ll need to change it often. If you choose a sediment filter with a higher micron size and your water contains fine sediments, then these will pass right through the filter continuing to wreak havoc in your appliances. If you own an UV water filter, a 5 micron sediment filter would be a good option to make sure that even finer sediments will be removed so nothing can absorb or shield bacteria from the effects of UV lights. 5 micron sediments are also suitable for reverse osmosis systems, where you need to protect the reverse osmosis membrane from damage or clogging. A 20 micron sediment filter would qualify as a general purpose sediment filter for the protection of your washing machine or bathroom faucet.

Type of sediment filter – polypropylene vs pleated sediment filters

Pleated sediment filters have a slight advantage over polypropylene ones in the sense that once a polypropylene sediment filter is clogged it cannot be reused. A pleated filter may offer a slightly longer service life, as most of these filters are cleanable, offering you a slightly better filter life.

Here at, you can choose from a varied line of pleated, polypropylene, or wound string sediment filters from world-class water filter manufacturers such as Puricom, Watts, Spectrum and Pentair.
