If you install your filter in the wrong direction, air will have a hard time flowing through the filter's material and your air handler will have to work overtime to make up for the loss of airflow.
Place the new engine air filter in the filter box. Insert it with the rubber rim facing up. Ensure that it is seated correctly. Put the top of the housing back on and put the fasteners back on.
When installing the air filter in the HVAC unit, ensure the arrow should always point towards the blower. This direction ensures that the air flows through the filter material correctly, thereby effectively trapping the particles.
The air filter has two sides, one more porous than the other. It is designed in such a way for the efficient functioning of the system. Putting the Air Filter backward can cause a lot of harm, not only to your air filter but to the whole HVAC system.
If you install your filter in the wrong direction, air will have a hard time flowing through the filter's material and your air handler will have to work overtime to make up for the loss of airflow. This is not only a waste of energy, but it can also possibly damage your air conditioner or heating system.
Your Engine Air Filter is Designed for Your Vehicle
When properly installed it only allows filtered air through to the engine. If debris sneaks by the wrong filter, it can pit and scratch your cylinders, which lowers horsepower and can lead down the path to overheating the block, cracking or even seizing.
If the filter is placed in the wrong direction, the finer pores on the other side of the filter will make it difficult for air to pass through the system. When that happens, there will also be a decrease in the cooling performance of the AC.
They should always be installed with the arrow pointing toward the furnace or air handler and away from the return duct. This orientation ensures that the filter can effectively trap dust and debris before the air reaches the furnace. Install the new filter in the same direction as the old filter when replacing it.
If your filter uses air flow direction arrows, make sure these arrows point toward the cabin, aligning with the air movement from the outside into your vehicle. If your filter uses UP and DOWN arrows, the UP arrow should face upwards, which typically means the air flows downward into the cabin.
The most common problem you will face with a backwards facing filter is simple inefficiency. If your furnace is forced to blow air through the non-porous end of a filter, it will take more energy to do so. The blower will be overworked and you will pay more money for your heating.
The arrow on your air filter should point towards the blower in your HVAC unit. This ensures that the filter catches particles and debris before they enter the system, protecting the internal components from damage. Air filters are designed with different levels of filtration capabilities.
Installing an air filter backward can damage your furnace or HVAC system, as the airflow will be decreased dramatically. A backwards filter prevents air from flowing into the furnace, which prevents air from flowing out of the furnace.
Incorrect filter installation or installing the wrong filter can leave your engine open to dirt and debris. When the engine's air intake is not completely covered by a filtering element, extensive damage can occur.
A dirty air filter can certainly impede your air conditioner's ability to cool and after time could cause unnecessary strain on the entire system. Another common potential reason is that your compressor has failed.
Place your air purifier in a central area of the room to allow for efficient airflow and circulation. This means you should keep your device away from walls, corners, and other obstructions (more on why in a second).
Position the airflow arrow so that it points in the direction the air is flowing. In addition to clean air, filters also protect your HVAC system from debris and dirt buildup. The airflow arrow should point towards the furnace/blower motor to collect harmful particles before it reaches the furnace's equipment.
