Thank you for shopping a 100% women owned and Texas-based small business!
The PERMANENT GRID is a simple installation which is placed into the air returns one time. It is attached to the 1/2 inch lip in the opening where the filter sits and stay there permanently. Once they are installed, it is ONLY necessary to replace the Blue Screen.
Our best value, the Blue Screen cost $4 less than the Green Screen MERV 10. The Blue Screen 1" Starter Pack includes everything you need to get started cleaning the air you breathe. It includes one permanent grid and 3 of our BLUE SCREEN air filters, and printed installation instructions. Comparable to MERV 7.
The Blue Screen is often used for Commercial applications. They are also for Residence that do not have allergies and have to change their filter often because of the # pets in the home.
We also HIGHLY RECOMMEND you use them during remodeling. You should change these more often, sometimes every week, and they are $4 less cost than the Green Screen MERV 10! Don't get trapped in the thought of buying the least expensive store-bought filters and change them often because they WILL let a LOT of the construction dust through. No need to pay for duct cleaning and unit coil cleaning after all the expense of the remodel.
