A/C Maintenance: How To Replace Your Air Conditioner’s Air Filter

Air conditioners have always been popular, but they used to be expensive to buy and costly to operate. These days they are cheaper to buy. It is not so bad if you live somewhere where you need heating for three months and cooling for three months, but if you live somewhere where you have one unit or other running twenty-for hours a day, seven days a week, it is still costly.

That is, the actual moving parts, lubricants and other fluids have to be checked professionally every two years (or whatever it says in your instruction manual). There are other parts though that need to be checked more the air being cleaned properly.

The good news is that you can do this maintenance yourself. I am talking about the washable air filter. All good, modern air conditioning units come with an in-built filter. It depends on the sophistication of your air conditioner, what its filter can trap, but most will filter small particles such as pollen and traffic pollution out of the air it is circulating in the room.

These filters need to be cleaned or replaced fairly regularly and you will have to check your air conditioner’s manual to find out what you can do. Frequently, it will say that they can be cleaned two or three times with either soapy water and a tooth brush or vacuumed clean. After that they have to be replaced, in order for the unit to be completely effective.

If you need to replace your air filter, you may find the following advice useful.


The best place to start is either the main dealer for your brand of air conditioner, the people you bought it from or the firm who fitted it for you. At least, you know you can trust them, even if it is only a case of ‘better the devil you know’. Many of the stores that sell other brands of air conditioner may stock filters for your sort as a sideline too.

You are already making use of the Internet, so that is another good place to check for current prices and bargains, before you go traipsing around town. ‘Fore-warned is fore-armed’, as they say. You can utilize the price knowledge you acquire from your Internet surfing as a bargaining tool to get the best price locally.

If that does not work or you just cannot be bothered, order on line and your air conditioner filter will be with you in a few day anyway. By the way, like with vacuum cleaner bags, it is normally better to buy several at a time. For example, if you know that they will withstand three washes, then each filter will last four months. Why not buy three and be done with it for a year?

The Benefits of Using Washable Air Filters

air-filter-washableFilters used in the heating, ventilation, and air-conditioning systems are known as HVAC filters. Indoor air pollution is one of the most serious forms of pollution affecting every individual. Air filters help in reducing air pollutants like dust, smoke, and pollen in a particular area keeping the air clean.

Home air filters draw the air within the room which consists of various particles and pollutants like fabric, particles of human skin, pollen, insect droppings and so on. All these particles are caught in the filter as the air passes through. The air is then heated or cooled and then thrown back into the area of the house through some ducts in the system.

There is a filter even at the air exhaust to prevent any further pollutant from going back into the area. This way filters are the major barriers which help remove any pollutants. Since many kinds of pollutants get stuck to the filters during this process, they need to be cleaned and replaced regularly to maintain the efficiency of the system.

Types of Air Filters:

Deep Pleated: They are used in first heating and cooling systems and are 5″ to 6″ deep. They have a reusable frame, but the media should be replaced at least once a year.

Washable: They can be washed using water and reused every month. They are 1″ deep. They have a longer life and are more expensive.

Flat: They are made of cotton of 1″ deep size and are disposable. They can capture smaller particles. They need to be changed every two to three months.

Polyester or fiberglass: They are cheap and disposable. They capture larger particles and protect the heating and cooling system. They are available in 1″ deep size.

Electronic cleaner: They run on electricity and are permanently fixed in the heating and cooling system. They are very efficient and expensive as well.

Furnace filters and dust filters are also popular choices for home ventilation especially to keep away allergies and asthma caused by pollutants. Many people claim that they benefit from such filters although there is no scientific proof that the usage of an air filter can help keep away such diseases directly.

When the level of pollutants in the air is lesser, airborne diseases can be controlled to a great extent inside the house. Commercial air filters are also similar in function but much larger in the scale of application. Purolator filters are one of the popular choices for such applications. The most popular by far are the reusable air filters that can be washed.

Home air filters are quite effective in keeping pollutants away and efficiently clean the air. Their efficiency can be affected by the increasing level of pollutants during varying weather conditions. It is essential to maintain and clean them regularly and replace the filters whenever necessary.
