How to Check if Your Air Filter is Installed Correctly

HVAC systems are responsible for circulating air throughout the house, and it is important to make sure that the air filter is installed correctly. The direction in which you place the filter in the frame is essential, as the arrow should point towards the fan. If it is not, then the air filters are not doing their job. Fortunately, checking the air filter on most cars is quite easy.

You'll need a screwdriver and you may also need to disconnect one or two electrical connectors. Refer to your owner's manual for location and removal procedure. Basically, you open the air box, remove the air filter and look at it. There is no real test procedure, only a purely visual inspection.

The filters are designed so that air flows in only one direction through them. Most filters have arrows printed on the side that indicate the correct direction in which the filter should be installed. A filter facing the wrong side will not capture dust particles very well and they will end up floating in the air in the house instead of being trapped by the filter. When properly installed, the arrows on the filter should point towards the oven. When your car is idling or stopped, you should feel and hear the gentle vibrations of an efficient engine.

If you notice unusual noises, in particular a coughing, clicking or spitting noise, this suggests that the engine is not getting enough airflow, which means that the air filter needs to be replaced. Some older vehicles have permanent air filters and some off-road vehicles have more complex filters with wet and dry elements. For more information on how to check and replace a dirty air filter, talk to an expert expert at your local NAPA AUTO PARTS store. This is because a dirty and clogged air filter will significantly impair the efficiency of the boiler and air conditioner. Inadequate air supply can cause carbon deposits to build up in the engine, eventually triggering the engine check light.

If it smells like gasoline when starting the car, it is because not enough air enters the fuel injection system and the excess unburned fuel leaves the car through the exhaust pipe (hence the smell). The engine air filter prevents this material from damaging the engine, and a dirty air filter is a sign that it is actually doing its job. Buy the correct filter for your vehicle's year, make, model and engine size, and compare the old and new side-by-side to confirm that they fit correctly. Your engine compensates for this by consuming more fuel to produce enough power to move the same distance or speed as you could with a clean filter. A visual inspection of the air filter under bright light will show a lot of dirt, but not all tiny particles can be easily seen.

An air purifier or air filter is a device that can be used with the HVAC system that helps remove contaminants from indoor air. To ensure that your air filter is installed correctly, make sure that all arrows printed on it point towards your oven. If you have any questions about how to check or replace a dirty air filter, talk to an expert at your local NAPA AUTO PARTS store or contact Hyde's, your Coachella Valley air conditioning contractor.
