Why companies opt to invest in self-cleaning filters

The reach of self-cleaning filters spans across many sectors, but what exactly is it about these parts that are so beneficial that they are producing such a high growth rate?

Warrington’s rich industrial history has been pivotal to the town’s success.

In recent years, self-cleaning filters are becoming more popular and more widespread.

And it’s not just to do with the fact that technology is becoming more prevalent in industry – it’s to do with more business owners realising the increasing befit of using parts such as these.

A recent report revealed that the global self-cleaning filter industry has grown from being worth just over £4 billion in 2017 to a predicted £6 billion in 2022 – a compound annual growth rate of 7.4%.

The reach of self-cleaning filters spans across many sectors, but what exactly is it about these parts that are so beneficial that they are producing such a high growth rate?

This article is all about the benefits of self-cleaning filters, and why now is the time to invest.


It’s natural for every business leader to want to save costs for their company. Though the challenge is that many companies still fail to differentiate between short-term and long-term savings.

A self-cleaning filter can seem like an unnecessary cost – “why would we invest in this machine when we can have our employees clean the filters themselves?” and this attitude is particularly common in smaller companies with a corresponding reduced turnover. It can seem like an easy cost-cutting decision to come to when you’re thinking about the initial cost, that you would avoid more costly filters.

Yet a long term view reveals that costs would be saved over time.


Automation now dominates our lives, and one area where it is enjoying growing attention is in the supply chain and industrial sectors.

The increased demand for automation in the supply chain shows no signs of slowing down, and self-cleaning filters are an essential part of a fully automated supply chain. The growth of specific sectors can be attributed to self-cleaning filters. The wastewater treatment industry, for example, has been able to increase operations with ease thanks to self-cleaning filters reducing Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS).

Another industry which is growing as a result of self-cleaning filters is pharmaceuticals. Companies which previously used conventional filters are now able to run production lines continuously – 24/7 if needed, to process solvents and chemicals associated with the production of pharmaceuticals.

These automated systems reduce costs associated with waste and labour and can be run non-stop without an operator once the initial set-up is complete.


Automation is required to free up employees to undertake more challenging or creative tasks, to reduce production costs and save money and to save energy.

Self-cleaning filters save on costs by minimising the energy used, and they create continuous water flow, eradicating the stop-start nature of non-self cleaning filter parts.

Not only does saving energy reduce the overall costs of your business, but it also helps the environment by reducing unnecessary energy being spent in larger-scale cleaning of regular filters once they have built-up.

A streamlined continuous cleaning of filters is naturally then more green all-round. Streamlining your process should be at the top of every business owner’s list of priorities. The rapid increase in the self-cleaning filter market can be attributed to companies taking advantage of this relatively novel type of machinery for the various benefits I have outlined here.

Development and research are continually carried out to improve the quality of self-cleaning filters.

Stainless steel self-cleaning filters, in particular, are becoming more common, the growth of which is attributed to the excellent properties such as corrosion resistance in aerated water, durability and reliability in high-pressure and chemical environments. And as we enter into a post-pandemic world, saving costs is going to be a top priority of many businesses. That’s why now is the right time for you to bring your assembly line into the 21st century and get serious about automating your business.
