Black Mold
Everybody is allergic to Black Mold, because it is toxic. I don''t believe you can filter out that, no matter how great a filter is....it needs to be removed by a professional if you have it in your home. Aside from that...why does Filtrete not assign a Merv rating?

Black Mold
I'm very allergic to Black Mold. These 4" filters suck up and trap the nasty little spores like a sponge. Living in a Condo unit that is partially underground, humidity control and constant filtration are very important. This filter is being used 24/7 and must be changed sooner than 1 year but I won't use anything else. AchooAllergy.com has great prices and super fast shipping. I was very pleased to find the filter packaged well and damage free when it arrived.

Product Questions

How often do these filters have to be changed? If I use a media filter, does that eliminate the need for other thinner furnace filters?

My furnace can accomodate either a 4in. filter or a 1 in. Could I use two filters or would this harm the unit by overly restricting airflow? If I can&#39t, which is better the 4in with a 1550 MPR or a 1 inch with a 1900? I noticed the 1inch only captured 93% while the 4inch said 97%. Being allergy free is more important than cost.
