How to choose a cabin filter

The cabin filter is a special element, designed to clean the air entering the cabin from dust, mechanical impurities, as well as all kinds of gases and odors. Right matched filter plays an important role not only in providing passenger comfort, but also in the correct the functioning of air conditioning and climate control.

We recommend reading an article from an expert on the choice of air filter and secrets of choosing an oil filter for the engine.

Top manufacturers

Preference should be given to well-known European brands, producing quality models whose products are installed in famous car brands at the factory:

  1. Mann;

  2. Knecht;

  3. Filtron;

  4. Hegnst;

  5. Mahle;

In order to select the optimal model for a particular car, you need to study the range of the catalog of interest manufacturer, as well as read thematic reviews users at specialized automotive sites. Exactly in the last you can find a lot of practical advice on how extend service life and maximize efficiency filter.

Types of cabin filters

Despite the apparent simplicity of the cabin filter design, models of this class can significantly vary in functionality plan. This is primarily due to the type material, as well as with the technology used in its manufacture. In this regard, the following types of “salons” are distinguished.

Barrier filters (paper)

Barrier filters

Simple and inexpensive models, the manufacture of which is used cellulose with the addition of synthetic materials. Is used for protect passengers from dust, exhaust fumes, poplar fluff and other irritants. Visibly extinguish odors and do not contribute moisture absorption.

Advantages

  • Inexpensive

  • Smells are stolen;

  • Protect from dust, poplar fluff, exhaust gases;

disadvantages

  • Are subject to burning;

  • They quickly become worthless;

Carbon filters

Carbon

Made of synthetic filter material with the addition of fine activated carbon. Prevent penetration of dust and debris into the cabin, as well as excellent adsorb unpleasant odors and harmful substances. Longer service life than similar models of barrier filters.

Advantages

  • Protect from dust and debris;

  • Do not support combustion;

  • Long service life;

  • Adsorb harmful substances and unpleasant odors, preventing them to the salon;

  • Do not absorb moisture;

disadvantages

  • More expensive than barrier analogues;

  • They require careful monitoring of the condition;

Cabin filter selection options

Despite the fact that the criteria for a quality cabin filter less than oil or fuel analogues, pay attention is required to the following technical features and nuances:

  1. Workmanship. Properly selected cabin filter must have maximum workmanship, uniformity distribution of filter material and be devoid of tearing places and other defects. Every nuance of the design is a potential weak link that contributes to the deterioration of functionality, and therefore external inspection is the first thing the choice should begin with filter.

  2. Filter weight. It is known for certain that the heavier the coal cabin filter – the more fine-grained activated carbon. This, in turn, allows us to talk about More functionality and better cleaning of the interior air;

  3. The quality of the frame and the fit of the car seat. Inadequate filters are installed loosely, forming along the perimeter of the gap and hole. They will let dust pass through dirt and unpleasant odors inside the passenger compartment. In order not to occurred, the filter should be inserted with force into the seat and precisely repeat its contours;

  4. The presence of a laminated layer on the back. In view of that the filter material is a dense, fleecy structure, mechanical elements of the heater motor are necessary protect from blown pile. It is for this purpose that it is used lamination coating on the inside;

  5. Dust transmittance. Percentage dust to volume ratio of air passing through the filter. According to European quality standards, should not be more than 8-10 percent;

  6. Drag coefficient. Shows how well does the filter pass air mass and how much it impedes passage. Measured in millimeters of water pillar. The value of this coefficient for the new filter is 40-50 mm. water art., worn out after operation the element passes air several times worse, about 150-200 mm. water Art.
