You should replace your home air filter every 3 months, or 90 days, for maximum efficiency. This is the general consensus, but there are certain factors to consider when determining when to change an old filter. If you don't have allergies, you can replace them approximately every 90 days. If someone in your family has mild to moderate allergies, you can put a better air filter on them or change them more often.
In general, you should check your air filter once a month to see how dirty it is. If you or a family member has a history of allergies or asthma, plan to change your filter once a month. If you have a pet that loses hair and enjoys spending time outside, you should change the air conditioner filter more frequently. When it comes to changing the air filter in your home, there are several factors to consider. If you live in a temperate climate that only needs air conditioning for a few weeks in the summer, you may be able to go months without changing it.
However, if someone in your family has allergies or asthma, it's best to replace the filter once a month. Additionally, if you have pets that lose hair and spend time outdoors, you should also plan to change the filter more often. It's important to make sure that you replace your air filters with ones of the correct size and type. With the new filter in hand, all you need to do is remove the old one and replace it with the new one in the same position as before.
The air filter is not used to purify the air you breathe, but rather to protect sensitive components of the air conditioning system. Regardless of whether you like changing filters or not, it's a good idea to have your system checked twice a year by an HVAC contractor. This will help ensure that your system is running efficiently and that your filters are being changed regularly. In conclusion, it's important to remember that when it comes to changing your home's air filters, there are several factors to consider. If someone in your family has allergies or asthma, plan to change your filter once a month. Additionally, if you have pets that lose hair and spend time outdoors, be prepared to replace the filter a month earlier than you would in a pet-free home.
