Knowing when the Filter should be Replaced


There are good reasons for changing your furnace filters on a regular basis. If you do not change them regularly, you may be losing some of the protection that they provide. Filters can become full of dust and other particles and then they will not trap the new particles that come through. This means they will be released into the air and you will be breathing them in. It will also make your furnace system less efficient because of extra wear and tear that it might have.

Dust is something that can affect the performance of your filter. If you get a lot of dust in your home then you will want to change more often. Dust can wear on the parts and components of the furnace when it operates. If you have no dust and no other factors then you change your filter every three months. You can also contact us and we can advise you on when it should be changed.

Animals are one thing that will affect when your filter needs to be changed. If you have more than one pet, then you will need to change the furnace filters more often than if you have none. Generally those with multiple animals will change a one or two inch filter every month. If you only have one pet then you can change that and change the filters every two, four and six months depending on the size of your filter.

Smoke can be detrimental to the filter and will make you have to change it sooner. Multiple smokers mean that one to two inch furnace filters should be changed monthly. Since this lets a lot of dust and dirt inside, it can impact how often a filter should be changed.

If you are not sure how often to change the filter, make sure to contact us. We can advise you on the correct schedule, and recommend what type of filter is right for your home.
