Why do I need to replace my Honda air filter?

Just like your car it is important to regularly service your construction machinery, otherwise you run the risk of damaging or destroying your machine.

A simple way to extend the life and improve the performance of your Honda engine is to replace the air filter.

The whole purpose of an air filter is to stop dust particles from the air entering your engine. It doesn’t take a rocket scientist to figure out that on a construction site, these machines are constantly doing hard yakka, long hours, and are exposed to extreme elements of dust and debris. So if you don’t service your small engines, which includes replacement of your air filter you are going to be without your machine sooner rather than later.

Our airfilters are especially designed to :

– extend the life of your engine

– improve the reliability of your engine

– increase the fuel efficiency of your engine (by up to 10%)

– reduce smoke and emissions making it a safer and more comfortable environment to work in.

– be cost efficient. The small price you pay for an air filter can save you from hundreds of dollars having to pay for an engine rebuild or new machine altogether.

Should I clean my Honda air filter?

Well that is really up to you. We recommend replacing air filters over cleaning them.

The problem with cleaning an air filter is that if it is not done correctly it can harm your small engine.

If you cleaning your air filter, instead of replacing it, you may only get the surface dust and grime from the filter. This can expose your engine to entrenched dust a grime. If dust gets in your engine it is going to cost you A LOT more than the couple of dollars spent on a new air filter. On top of this you also need to check all seals an ensure there are no cracks.  We are big supporter of people doing things more efficiently. It is easily cheaper for you to buy a new air filter if you consider the cost of your time, fiddling about trying to ensure it is thoroughly clean, and the consequences if you don’t clean it properly.

Overall, you will get much more peace of mind with a new replacement air filter installed.
