Just like the false truths about yetis and sea monsters, there are also a number of persistent myths about filters. We are now taking it upon ourselves to tackle the worst of these old wives’ tales.

In our new brochure, we clarify the 10 most common filter myths and dispel the misconceptions by providing hard facts and clear examples.  10 Mythus

The idea came from our Russian colleagues whose brochure on 10 myths about filters is already on the market in its third edition. It was precisely these arguments that we needed in many of the markets that I look after. We therefore revised the brochure and gave it a brand new design. The new version is a world away from a boring document full of never-ending blocks of text. It speaks to our customers in their language and the text is interspersed with appealing images. Ultimately, we want to dispel the myths about filters in a friendly and approachable way. Here are a few examples:

Myth No. 1: “The same paper is often used in both cheap and high-quality filters. After all, there are only a handful of filter paper manufacturers in the world.”

Wrong! While it is true that the number of manufacturers of filter materials is limited, the origin of the paper doesn’t really give us any clues about its quality and certainly doesn’t tell us anything about the performance capability of the filter. In short, the filter paper found in some cheap products is about as much good as a tissue made of sandpaper – and all that would give you is a bloodied nose.

Myth No. 7: “Instead of buying a new cabin filter, you can just brush the old one down.” 

Wrong! By using water and a brush, all you actually do is make your cabin filter look cleaner. Tiny particles, such as pollen, fungi and mould spores, however, cannot just be brushed away. In short, it’s never a good idea to experiment with your health. You should prioritise changing your cabin filter regularly, either once a year or every 15,000 km, for the sake of your health and safety when driving.

Myth No. 8: “As long as the size and thread match, oil filters are interchangeable. So there is no need to worry about finding a filter with the correct item number.”

Wrong! Even if a filter has the correct dimensions, that doesn’t automatically make it the right choice. The black casing may look reliable from the outside, but only a high-quality oil filter guarantees optimum protection. In short, it’s what’s on the inside that counts! Would you pick up any old packet of tablets just because it looked the same? Or would it depend on what was inside?

Globally persistent claims

I was astonished at how the same myths about filters seem to persist across the world. This is why we have initially produced the brochure in 12 languages, and have plans to roll out more world languages in future. I have been delighted with the positive response and would like to take this opportunity to thank all of my colleagues for their hard work. This publication from MANN-FILTER provides practical assistance for daily communications with customers and is also an entertaining read at the same time. Why not read it yourself? Many more myths are explained in the brochure ’10 myths about filters’ and  the website.
