How Often Should You Check Your 20x20x1 Air Filter?

They usually need to be changed every 30 days or less. Pleated air filters are more expensive at first, but they are also more efficient at trapping dust and particles from the air. Fiberglass air filters are the more affordable of the two, but less efficient at capturing airborne contaminants. In general, most air filter manufacturers and HVAC companies recommend changing the filter every 90 days or 3 months. That can change depending on the location of your home (e.g.

Ej. Dry and dusty climates), if you have pets and the age of your system and equipment. If you have pets at home, you should consider changing the filter every 60 days or 2 months, and in the case of homes with several pets or people with allergies or respiratory conditions, we recommend changing the filter every 20 to 45 days. Usually, vacation homes or empty houses that aren't used much can wait to change the filters every 9 to 12 months. The general consensus is that the more you use your home, the more you'll need to change the air filter.

However, experts suggest replacing it every 30 days if the air filter is made of fiberglass filters, which are of relatively poor quality. On the other hand, expensive pleated filters can work well if replaced once every three to six months. The most important thing to remember about air filters is to change them regularly. It is generally recommended to change residential air filters every 30 days if regular fiberglass filters are used. When air filters don't change, dust, pollen, dirt, and other contaminants accumulate and decrease filter efficiency.

The usual recommendations range from every 30 days for cheaper fiberglass filters (which often don't work to filter well) to up to 6 months for high-end pleated filters. Therefore, there is no clear answer as to how long the air filter can work efficiently before needing a replacement. If you have young children in your home, you'll need to change the air filter more often, once every 2 to 3 months. If you have an asthmatic or allergic person at home, change the filter every 6 weeks to ensure optimal indoor air quality. However, if it's impossible to replace the air filter for an extended period of time, spending more than 90 days isn't going to cause irreparable damage to your air conditioning system.

You'll find it easier to remember this important task if, first of all, you know how often you should change the air filter. According to the American Allergy and Asthma Foundation (AAFA), “indoor air quality is just as important as outdoor air quality”. The term air conditioner simply refers to air conditioning, while HVAC refers to heating, ventilation, and air conditioning. However, it will put unwanted pressure on your climate system, leading to poor air quality and poor air circulation. If you answer yes to this question, you'll want to change the filter every 6 weeks to maintain the best indoor air quality. When you buy a new air filter, you'll find the manufacturer's recommendations for the replacement program.

A general rule of thumb for pleated air filters (such as those made by FilterBuy) is to change them every 90 days. It is not used to purify the air you breathe, but to protect the sensitive components of your air conditioning system. 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 changing them before they get too clogged and dirty. Your home's air filters should be changed regularly in order to keep your system running smoothly and maintain optimal indoor air quality.
