Filtrete Air Filters

Filtrete air filters.
Because they do not need the size that I can, I cut one side of the filter so that it fits?
Is it dangerous? he is told not to board the departure. Does it make a difference?

Of course, everything at the end of news as strong as the original. Better still, for about $ 20 you can buy a tunable filter that lasts a lifetime.

The problem is that the board supports the media in the middle. If you remove the cardboard, then the filter can be sucked into the fan and you have to go and dig it up. In addition, you do not seal around the edges so that air bypasses the filter and does not make you good.
Buy another brand or see if you can put two filters together with tape. I also discovered that you can order filters to adapt to Lowe's or Home Depot probably their catalog. They stock only the most used formats. I bought a box and they worked great.

Do not cut the wrong size filter, it wont work properly and can damage your furnace. I'm not sure what size you want, but 3M manufactures a wide range of sizes. Perhaps the shop you visit does not simply make the size you need? Try the command line to find a larger selection.
