If you don't suffer from allergies, it's recommended to replace your air conditioner filters every 90 days. However, air conditioning professionals usually suggest changing them every 45 days for maximum efficiency. Make sure to use the correct size and type of air filter when replacing them. If your air conditioner is working properly, you can remove the filter and buy one that is identical.
Generally, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months. This may vary depending on the location of your home (e.g., dusty and dry weather), 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 households with several pets or people with allergies or respiratory conditions, we recommend that you change the filter every 20 to 45 days. Vacation homes or empty houses that aren't used much can wait to change filters every 9 to 12 months.
The more you use your home, the more often you'll need to change your air filter. The ideal is to change your air filter every three months, however, there are certain factors to consider when determining when to replace an old filter. If you don't have allergies, it's a good idea to change your air filters every 30 to 45 days. Changing the air filter on your HVAC system is a simple and easy step to take to keep your system running smoothly and promote superior indoor air quality.
As a general rule, it's a good idea to replace your HVAC system air filter every month. The air conditioner air filter is responsible for removing most of the particles from the air, which can affect indoor air quality and the efficiency of the entire system. 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. Much of that hair is carried through the air and passes through the air conditioner filters, clogging it up quickly.
As mentioned above, there is no set lifespan for an air filter, but it requires an evaluation of many different aspects. If someone in your household has a condition that affects their lungs and breathing, change the filters more often. However, many homeowners are unaware of how often air filters need to be replaced, making their system vulnerable to damage. However, the smaller the appliance used to cool the small space, they often come with smaller filters, so you may have to change the filter as often as a filter in a larger house.
