A pleated air filter should be changed every 30-60 days, while a filter with two folds should be replaced every 3 months. A three-fold air filter should be changed every 120 days, and a four-fold air filter should be changed every 6 months. Fiberglass air filters are the more affordable option, but they are less efficient at capturing dust and particles from the air. These filters usually need to be changed every 30 days or less.
Different types of ovens or air conditioning filters have different specifications for when they should be replaced. Pleated air filters are more expensive than fiberglass filters, but they are made of higher quality materials. These filters can last 3 to 6 months, depending on several factors. Low-cost fiberglass filters need to be changed every 30 days, while pleated air filters are slightly more expensive but can last up to 6 months. A good rule of thumb is to replace pleated filters every 90 days. If you have electrostatic or washable filters, you should wash, dry, and reinstall them once a month.
Washable filters are more environmentally friendly and, if properly cleaned and reused, can last 5 to 10 years. If you live in a “smaller” house, your air conditioners and ovens must pump less air with the same temperature change, which could mean fewer filter changes. If you have allergies, you can reduce symptoms by using a high-quality air filter and adopting a more frequent replacement program. Replace the air filter to restore airflow, improve heating and cooling efficiency, and increase air quality throughout the house. For example, a family of four will need to change their air filters more often than a single-person home. If you have poor air quality outside or if you have pets inside, you'll need to change your air filter more often. If the owner has changed the air filter and is still noticing these problems, it is advisable to call a professional to help you fix the problem at the root. The fewer occupants there are in a house, the less pollutants and debris will accumulate in the air filters.
You'll find it easier to remember this important task if you learn how often you should change your air filter in the first place. It could cause further damage to the system (freezing of the coils, accumulation of liquid in the air compressor or heat pump). When you remove the air filter from the air conditioner, if you bring it closer to a light source, you can see if the filter is dirty or clogged. If you can't see the light through the filter, it's time to change it. If you're installing the air filter in a vacation home, cabin, or other property that you don't normally use, you can usually wait a little longer to change it. Children are more sensitive than adults to indoor air pollutants, such as mold, dust mites, dandruff and pollen, so turn your home into an oasis by using quality air filters and change them before they get too clogged and dirty.
The manufacturer of an air filter usually explains how often the air filter should be replaced in its installation instructions. In addition, not replacing the air filter accordingly can cause the homeowner's energy bill to increase, since clogged filters make the system work harder to circulate air. By filtering these contaminants, an oven filter improves the quality of the air inside a home, making it easier to breathe.
