You can improve the maintenance and longevity of your system by changing your filters regularly. It should be done at least with the change of the heating and cooling seasons or more often than that depending on your conditions.
One item that you do need when you’re changing the filter going into your handler is a filter lock , which is a new item. It’s magnetically applied and comes in 2 strips so that you can add this and adjust to the height of your filter. The filter lock seals over the outside of the filter itself to prevent allergens and pollutants from entering into the filter, extending the life of your filter and the efficiency of it inexpensively.
