If someone in your home has asthma or allergies change your filter every

6 Weeks

to ensure indoor air quality is at its best.

to avoid shedding and odor buildup.

If you have young children change your filter every

as having clean air is even more important with children in your home.

These filters are thicker than my prior filters. I am sure they will catch more impurities than the last ones

The filter looked to be of good construction; it wasn't build with flimsy metal. It was made to the correct dimension and fit the air handler perfectly. I would definitely re-order from discount filters, given the competitive pricing and quality of the filter.
