How to Change Air Conditioner Filter

There are various applications that require good quality air for effective functioning. So, such machines and devices have air filters, so that the air taken in is filtered to prevent the entry of dust and other impurities. You might have seen air filters in car engines and air conditioners, which are the most common examples of the use of air filters in day-to-day life. However, once the air filter gets clogged, it affects the effective functioning of the machine. Hence, replacing such air filters are very necessary. Replacing air filters is not a difficult task and you can do it yourself, if you have a basic idea about the right technique.

Why and When to Change Your Air Conditioner Filter

In case of air conditioners, clogged air filters can reduce air flow into the building, reduce the cooling effects, let in the dust and other particles to the device and indoors, and can eventually damage other parts, like blowing fan. This causes the machine to use more power for working and results in soaring power bills. Apart from that, you get a supply of air with impurities and allergens. All these factors make it necessary to replace air conditioner filter periodically. It can also happen that the air filter in your air conditioner is meant for cleaning and refitting after a stipulated period. You can replace such filters also, if they are in a really bad shape. In general, it is recommended that air filters in air conditioners have to be changed every 30 to 60 days, if they are in regular use. You may also refer to the manufacturer's instructions for changing air conditioner filter. Replacing the filter is not a daunting task, if you know the right way.

How to Change Your Air Conditioner Filter

• Shut off the air conditioning system and try to locate the filter. In case of a furnace system, the air filter can be found attached to the AC unit itself, but, in a forced air system, air filter is usually located over a vent, through which the air is taken in. Mostly, the filter will be covered by a metal grill.
• Once you locate the air filter, check its size, which may be noted on the side of the device, or else call up the manufacturer for the details of the air filter installed in your air conditioning system.
• As you get the dimensions of the air filter in the system, purchase a new one of the same size. There are many types of air conditioner filters and you can choose the one best suited for you. Those who live in warm and dusty climates may go for more efficient filters.
• Before removing the old filter from the system, you have to note how the filter is attached to the system and make sure to mark the direction of airflow (look for similar markings on the old filter). Such details may be needed when you have to fix the new filter.
• Remove the old filter from the system and clean the grill with a vacuum cleaner. Now, fix the new air filter, in the same way as the old one was attached to the system. Take care of the right airflow direction, while fitting the new air filter. Once the new air filter is fixed, close the covering of the filter carefully.

Air conditioner filters are quite inexpensive and are easy to replace. You can do it yourselves, if you have a little know how of the technique. Replacing air filters can be done at stipulated intervals or as per the instructions of the manufacturer.
