The particle filter is a quite recent technology that is designed to take out harmful particles from the exhaust gases of latest diesels. It has long been discovered as the miracle solution to these pollution problems. Nevertheless, it doesn’t work as well as intended and causes more problems than it resolves, which is why we will discover today when changing the particulate filter of a Lexus RX? . To get this done, to begin with, we will find out what the particle filter on your car is used for, and then when to change the particle filter on your Lexus RX.

What’s the point of a Lexus RX’s particulate filter?

So we begin our content page with the explanation to do this component recently built in into diesel automobiles. As we described quickly in the introduction, the goal of this filter was to resolve the problems of pollution and harmfulness of exhaust gases from Lexus RX automobiles. Its functioning principle is to store exhaust gases that are unburned or that still contain harmful particles, and when it is at a sufficiently high temperature to bring about a second combustion that will finish burning and eliminate all these carcinogenic particles. Sadly, to reach this very high engine unit temperature, you have to be on the highway or have your Lexus RX engine unit revving up. So we have discovered over time that vehicles that are specifically on short trips or in the city do not enable the particulate filter to burn these gases and we will discover in the next section that these problems can force you to change the particulate filter of your Lexus RX .

The second one, the one we are interested in today, works with precious metals that will produce a chemical reaction at high temperature and bring about the regeneration of the filter and the evacuation of the carcinogenic materials. Nevertheless, as described earlier, it requires very high temperatures, if these are not reached the filter will clog. If the filter is not regenerated manually, drive at high speed for about 20 minutes to reach this temperature and thus regenerate your filter, you will clog it and risk damaging your turbo, your EGR valve or your engine unit.
